Non-motor associative learning in patients with isolated degenerative cerebellar disease. (1/486)

In recent decades it has become clear that the cerebellum is involved in associative motor learning, but its exact role in motor learning as such is still controversial. Recently, a contribution of the cerebellum to different cognitive abilities has also been considered, but it remains unclear whether the cerebellum contributes to cognitive associative learning. We compared nine patients with an isolated cerebellar degenerative disease in a cognitive associative learning task with 10 controls. Patients and controls were matched for age, sex, handedness, level of education, intelligence and capabilities of visual memory. The subjects were asked to learn the association between six pairs of colours and numerals by trial and error. Additionally, a simple reaction time and a visual scanning test were conducted in order to control for the influence of motor performance deficits in cerebellar patients. In comparison with the controls, it took the patients significantly longer to learn the correct associations between colours and numerals, and they were impaired in recognizing them later on. Two patients showed no associative learning effect at all. Neither the simple reaction time nor the visual scanning time correlated substantially with the results of associative learning. Therefore, motor-associated disabilities are unlikely to be the reason for the learning deficit in cerebellar patients. Our results suggest that the cerebellum might contribute to motor-independent processes that are generally involved in associative learning.  (+info)

Contralateral deafness following unilateral suboccipital brain tumor surgery in a patient with large vestibular aqueduct--case report. (2/486)

A 68-year-old female developed contralateral deafness following extirpation of a left cerebellopontine angle epidermoid cyst. Computed tomography showed that large vestibular aqueduct was present. This unusual complication may have been caused by an abrupt pressure change after cerebrospinal fluid release, which was transmitted through the large vestibular aqueduct and resulted in cochlear damage.  (+info)

Anticonvulsant-induced dyskinesias: a comparison with dyskinesias induced by neuroleptics. (3/486)

Anticonvulsants cause dyskinesias more commonly than has been appreciated. Diphenylhydantoin (DPH), carbamazepine, primidone, and phenobarbitone may cause asterixis. DPH, but not other anticonvulsants, may cause orofacial dyskinesias, limb chorea, and dystonia in intoxicated patients. These dyskinesias are similar to those caused by neuroleptic drugs and may be related to dopamine antagonistic properties possessed by DPH.  (+info)

Intrameatal aneurysm successfully treated by meatal loop trapping--case report. (4/486)

A 77-year-old female presented with a rare intrameatal aneurysm manifesting as sudden onset of headache, hearing loss, tinnitus, and vertigo associated with subarachnoid hemorrhage. Meatal loop trapping was performed. After surgery, the patient's functions recovered almost completely, probably because of the preservation of the 7th and 8th cranial nerves and the presence of effective collaterals in the area supplied by the anterior inferior cerebellar artery.  (+info)

Remote regional cerebral blood flow consequences of focused infarcts of the medulla, pons and cerebellum. (5/486)

The aim of this study was to evaluate regional and remote diaschisis of inferior brain stem or cerebellar infarcts in 25 patients presenting with relatively limited lesions. Patients presented with medullary, pontine or cerebellar infarction. METHODS: Lesions were evaluated on MRI (0.5 T). Regional cerebral blood flow (rCBF) was assessed by means of SPECT, after injection of 9rmTc-hexamethyl propyleneamine oxime (HMPAO) and, when possible, inhalation of 133Xe in the same session. For each method, asymmetry indices (Als), comparing contralateral to ipsilateral rCBF values, were calculated in four areas of each cerebral hemisphere and in the cerebellum and later compared with values obtained in healthy subjects (P = 0.05). RESULTS: Higher rCBF values were observed in the contralateral cerebellum in 2 of 7 patients with selective lateral medullary lesions, and cerebellar Als were significantly increased. When a cerebellar infarct was associated with a lateral medullary lesion, the cerebellar and contralateral hemispheric asymmetries were more severe. Unilateral paramedian pontine infarcts had more frequent consequences on the cerebellum (2 of 3 cases), with rCBF or tracer uptake being reduced in the ipsilateral or the contralateral lobe. Inverse cerebral hemispheric asymmetry could then be observed. Bilateral pontine lesions were difficult to evaluate. Using 99mTc-HMPAO, discrete cerebellar asymmetry was observed in 3 of 6 cases. Pure cerebellar infarcts in the posterior inferior cerebellar artery territory were always associated with a severe ipsilateral flow drop in the cerebellum, and contralateral hemispheric diaschisis was frequent (3 of 4 patients), predominating in the frontotemporal cortex and subcortical structures. This was also more obvious using 99mTC-HMPAO than 133Xe. Variance analysis showed that hemispheric diaschisis was more severe in mixed brain stem and cerebellar infarcts than in pure cerebellar or brain stem lesions. Furthermore, cerebellar and hemispheric AI values were not correlated with measurements of clinical deficits, disability or handicap. CONCLUSION: Unilateral and limited inferior brain stem lesions can have ipsi- or contralateral consequences on the cerebellum and cerebral hemispheres rCBF. These remote effects are related to lesions of the main pathways joining these structures, resulting in deactivation and, in some cases, overactivation. Contrary to what has been suggested, consequences on cerebral hemispheres are more severe in mixed cerebellar and brain stem infarcts than in pure cerebellar lesions.  (+info)

Multiple large and small cerebellar infarcts. (6/486)

To assess the clinical, topographical, and aetiological features of multiple cerebellar infarcts,18 patients (16.5% of patients with cerebellar infarction) were collected from a prospective acute stroke registry, using a standard investigation protocol including MRI and magnetic resonance angiography. Infarcts in the posterior inferior cerebellar artery (PICA)+superior cerebellar artery (SCA) territory were most common (9/18; 50%), followed by PICA+anterior inferior cerebellar artery (AICA)+SCA territory infarcts (6/18; 33%). One patient had bilateral AICA infarcts. No infarct involved the PICA+AICA combined territory. Other infarcts in the posterior circulation were present in half of the patients and the clinical presentation largely depended on them. Large artery disease was the main aetiology. Our findings emphasised the common occurrence of very small multiple cerebellar infarcts (<2 cm diameter). These very small multiple cerebellar infarcts may occur with (13 patients/18; 72%) or without (3/18; 22%) territorial cerebellar infarcts. Unlike previous series, they could not all be considered junctional infarcts (between two main cerebellar artery territories: 51/91), but also small territorial infarcts (40/91). It is suggested that these very small territorial infarcts may be endzone infarcts, due to the involvement of small distal arterial branches. It is possible that some very small territorial infarcts may be due to a microembolic process, but this hypothesis needs pathological confirmation.  (+info)

Failure of cerebellar patients to time finger opening precisely causes ball high-low inaccuracy in overarm throws. (7/486)

We investigated the idea that the cerebellum is required for precise timing of fast skilled arm movements by studying one situation where timing precision is required, namely finger opening in overarm throwing. Specifically, we tested the hypothesis that in overarm throws made by cerebellar patients, ball high-low inaccuracy is due to disordered timing of finger opening. Six cerebellar patients and six matched control subjects were instructed to throw tennis balls at three different speeds from a seated position while angular positions in three dimensions of five arm segments were recorded at 1,000 Hz with the search-coil technique. Cerebellar patients threw more slowly than controls, were markedly less accurate, had more variable hand trajectories, and showed increased variability in the timing, amplitude, and velocity of finger opening. Ball high-low inaccuracy was not related to variability in the height or direction of the hand trajectory or to variability in finger amplitude or velocity. Instead, the cause was variable timing of finger opening and thereby ball release occurring on a flattened arc hand trajectory. The ranges of finger opening times and ball release times (timing windows) for 95% of the throws were on average four to five times longer for cerebellar patients; e.g., across subjects mean ball release timing windows for throws made under the medium-speed instruction were 11 ms for controls and 55 ms for cerebellar patients. This increased timing variability could not be explained by disorder in control of force at the fingers. Because finger opening in throwing is likely controlled by a central command, the results implicate the cerebellum in timing the central command that initiates finger opening in this fast skilled multijoint arm movement.  (+info)

Preserved performance by cerebellar patients on tests of word generation, discrimination learning, and attention. (8/486)

Recent theories suggest that the human cerebellum may contribute to the performance of cognitive tasks. We tested a group of adult patients with cerebellar damage attributable to stroke, tumor, or atrophy on four experiments involving verbal learning or attention shifting. In experiment 1, a verb generation task, participants produced semantically related verbs when presented with a list of nouns. With successive blocks of practice responding to the same set of stimuli, both groups, including a subset of cerebellar patients with unilateral right hemisphere lesions, improved their response times. In experiment 2, a verbal discrimination task, participants learned by trial and error to pick the target words from a set of word pairs. When age was taken into account, there were no performance differences between cerebellar patients and control subjects. In experiment 3, measures of spatial attention shifting were obtained under both exogenous and endogenous cueing conditions. Cerebellar patients and control subjects showed similar costs and benefits in both cueing conditions and at all SOAs. In experiment 4, intra- and interdimensional shifts of nonspatial attention were elicited by presenting word cues before the appearance of a target. Performance was substantially similar for cerebellar patients and control subjects. These results are presented as a cautionary note. The experiments failed to provide support for current hypotheses regarding the role of the cerebellum in verbal learning or attention. Alternative interpretations of previous results are discussed.  (+info)

ataxia consist of gait impairment, unclear ("scanning") speech, visual blurring due to nystagmus, hand incoordination, and tremor with movement. These result from the involvement of the cerebellum and its afferent and efferent pathways, including the spinocerebellar pathways, and the frontopontocerebellar pathway originating in the rostral frontal lobe. True cerebellar ataxia must be distinguished from ataxia associated with vestibular nerve or labyrinthine disease, as the latter results in a disorder of gait associated with a significant degree of dizziness, light-headedness, or the perception of movement (Chap. 21). True cerebellar ataxia is devoid of these vertiginous complaints and is clearly an unsteady gait due to imbalance. Sensory disturbances can also on occasion simulate the imbalance of cerebellar disease; with sensory ataxia, imbalance dramatically worsens when visual input is removed (Romberg sign). Rarely, weakness of proximal leg muscles mimics cerebellar disease. In the patient ...

The cerebellum, principally a motor organ, is responsible for the coordination of movements, especially skilled voluntary ones, the control of posture and gait, and the regulation of muscular tone. In the last decade it has come to be appreciated that the cerebellum may play a role in the modulation of the emotional state and some aspects of cognition. The mechanisms by which these functions are accomplished have been the subject of intense investigation by anatomists and physiologists. Their studies have yielded a mass of data, testimony to the complexity of the organization of the cerebellum and its afferent and efferent connections. A coherent picture of cerebellar function is now emerging, although it is not yet possible, with a few notable exceptions, to relate each of the symptoms of cerebellar disease to a derangement of a discrete anatomic or functional unit of the cerebellum. ...

While gray matter volume increase was larger in cerebral areas in patients compared with controls, the opposite was found in the cerebellum, with a more pronounced increase in gray matter volume in controls compared with patients. This implies that motor improvements in patients with cerebellar degeneration appear to be driven by cerebral structures unaffected by the disease. In both cerebellar patients and controls, gray matter changes were found in supratentorial areas known to contribute to various aspects and stages of motor learning. In cerebellar patients, most changes were observed in the frontal cortex, whereas gray matter changes in occipitotemporal areas and basal ganglia prevailed in healthy controls.. We found no evidence to substantiate the claim that cerebellar patients increasingly recruit the basal ganglia circuits to compensate for their motor deficit (Wessel et al., 1995). In the patient group, the most compelling change in gray matter volume was seen in the dorsal premotor ...
The cerebellum: Once the movement of the arm is initiated, sensory information is needed to guide the finger to its precise destination. In addition to sight, the most important source of information comes from the "position sense" provided by the many sensory neurons located within the limbs (proprioception). Proprioception is what allows an individual to touch their nose with their finger even with the eyes closed. The balance organs in the ears provide important information about posture. Both postural and proprioceptive information are processed by a structure at the rear of the brain called the cerebellum. The cerebellum sends out electrical signals to modify movements as they progress, organizing the voluntary commands into a tightly controlled pattern. Cerebellar disorders cause ataxia (inability to control the force, fine positioning, and speed of movements). Disorders of the cerebellum may also impair the ability to judge distance so that a person under- or overreaches the target ...
Background and purpose Arterial spin-labeling (ASL) was recently introduced as a noninvasive method to evaluate cerebral hemodynamics. The purposes of this study were to assess the ability of ASL imaging to detect crossed cerebellar diaschisis (CCD) in patients with their first unilateral supratentorial hyperacute stroke and to identify imaging or clinical factors significantly associated with CCD. Materials and methods We reviewed 204 consecutive patients who underwent MRI less than 8 hours after the onset of stroke symptoms. The inclusion criteria were supratentorial abnormality in diffusion-weighted images in the absence of a cerebellar or brain stem lesion, bilateral supratentorial infarction, subacute or chronic infarction, and MR angiography showing vertebrobasilar system disease. For qualitative analysis, asymmetric cerebellar hypoperfusion in ASL images was categorized into 3 grades. Quantitative analysis was performed to calculate the asymmetric index (AI).

The item is aimed at finding evidence of a unilateral cerebellar lesion. Test with eyes open. In case of visual defect, ensure testing is done in intact visual field. The finger-nose-finger and heel-shin tests are performed on both sides, and ataxia is scored only if present out of proportion to weakness. Ataxia is absent in the patient who cannot understand or is paralyzed. Only in the case of amputation or joint fusion, the examiner should record the score as untestable (UN), and clearly write the explanation for this choice. In case of blindness, test by having the patient touch nose from extended arm position ...
We know that when the cerebellum is damaged, it causes movement disorders in both speech and non-speech actions," says UW-Madison Waisman Center investigator Ben Parrell. "What we dont understand is why cerebellar damage leads to these disorders.". So Parrell, who is a new assistant professor of communication sciences and disorders at UW-Madison, set out to investigate.. In a recent study, he and his colleagues discovered that damage to the cerebellum diminishes our ability to predict consequences of an action and issue specific motor commands to the body - what researchers call "feedforward control.". Diminished feedforward - or predictive - control could explain speech difficulties often faced by individuals with cerebellar damage.. "If you can correctly predict what will happen after an action - like trying to say a specific word, for example - you can do things more fluidly, more rapidly because you dont need to monitor outcomes in real time," says Parrell.. In contrast, without properly ...

The cerebellum has been considered only as a classical subcortical center for motor control. However, accumulating experimental and clinical evidences have revealed that the cerebellum also plays an important role in cognition, for instance, in learning and memory, as well as in emotional behavior and in nonsomatic activities, such as visceral and immunological responses. Although it is not yet clear through which pathways such cerebellar nonsomatic functions are mediated, the direct bidirectional connections between the cerebellum and the hypothalamus, a high autonomic center, have recently been demonstrated in a series of neuroanatomical investigations on a variety of mammals and indicated to be potential pathways underlying the cerebellar autonomic modulation. The direct hypothalamocerebellar projections originate from the widespread hypothalamic nuclei/areas and terminate in both the cerebellar cortex as multilayered fibers and the cerebellar nuclei. Immunohistochemistry studies have offered ...

The spinocerebellar ataxias (SCAs) are a genetically heterogeneous group of dominantly inherited progressive ataxia disorders. More than 30 different gene loci have been identified so far. The most common SCAs, which together account for more than half of all affected families, are SCA1, SCA2, SCA3, and SCA6. Each of these disorders is caused by a translated CAG repeat expansion mutation. SCA1, SCA2, and SCA3 usually have an onset between 30 and 40, and SCA6 usually begins at the age of 50 to 60. In addition to progressive ataxia, SCA1, SCA2, and SCA3 frequently present with additional non-ataxic symptoms, including parkinsonism. Carbidopa/levodopa was found to have a good therapeutic effect on parkinsonism.. The SCA6 used to be considered a pure cerebellar disorder. However, a recent large study on natural history of SCAs found that patients with SCA6 often had nonataxia symptoms, an observation that challenges the view that SCA6 is a purely cerebellar disorder. Parkinsonism in SCA6 was rarely ...

We present a 7-year-old boy with acute cerebellitis who required an emergency ventriculoperitoneal shunt for hydrocephalus caused by cerebellar swelling. This represents a very unusual, potentially life-threatening complication of a usually self-limiting condition. Early diagnosis of this complication is essential in view of the propensity to sudden and fatal deterioration. Magnetic resonance imaging (MRI) is useful in differentiating this unusual course of acute cerebellar ataxia from that of a posterior fossa tumor. In developing countries, however, computed tomography (CT) is often the only existing diagnostic modality and access to MRI, when available, is limited. Our case demonstrates that the shape of the fourth ventricle on CT can be helpful in differentiating between a tumor and edema of the cerebellum and thus can assist in management ...

Results There were 383 patients with Friedreichs ataxia (FRDA), 205 patients with SCA and 168 controls. In FRDA, 31% of the variance of cerebellar signs with the CCFS and 41% of that with SARA were explained by disease duration, age at onset and the shorter abnormal repeat in the FXN gene. Increases in CCFS and SARA scores per year were lower for FRDA than for SCA (CCFS index: 0.123±0.123 per year vs 0.163±0.179, P,0.001; SARA index: 1.5±1.2 vs 1.7±1.7, P,0.001), indicating slower cerebellar dysfunction indexes for FRDA than for SCA. Patients with SCA2 had higher CCFS scores than patients with SCA1 and SCA3, but similar SARA scores. ...

Joubert syndrome is a rare autosomal recessive genetic disorder that affects the cerebellum, an area of the brain that controls balance and coordination. Joubert syndrome is one of the many genetic syndromes associated with syndromic retinitis pigmentosa. The syndrome was first identified in 1969 by pediatric neurologist Marie Joubert in Montreal, Quebec, Canada, while working at the Montreal Neurological Institute and McGill University. Most of the signs and symptoms of the Joubert syndrome appear very early in infancy with most children showing delays in gross motor milestones. Although other signs and symptoms vary widely from individual to individual, they generally fall under the hallmark of cerebellum involvement or in this case, lack thereof. Consequently, the most common features include ataxia (lack of muscle control), hyperpnea (abnormal breathing patterns), sleep apnea, abnormal eye and tongue movements, and hypotonia in early childhood. Other malformations such as polydactyly (extra ...

The cerebellum and the motor thalamus, connected by cerebellothalamic pathways, are traditionally considered part of the motor-control system. Yet, functional imaging studies and clinical studies including patients with cerebellar disease suggest an involvement of the cerebellum in olfaction. Additionally, there are anecdotal clinical reports of olfactory disturbances elicited by electrical stimulation of the motor thalamus and its neighbouring subthalamic region. Deep brain stimulation (DBS) targeting the cerebellothalamic pathways is an effective treatment for essential tremor (ET), which also offers the possibility to explore the involvement of cerebellothalamic pathways in the sense of smell. This may be important for patient care given the increased use of DBS for the treatment of tremor disorders. Therefore, 21 none-medicated patients with ET treated with DBS (13 bilateral, 8 unilateral) were examined with "Sniffin Sticks," an established and reliable method for olfactory testing. ...
Cerebellar neurons are generated from two germinal neuroepithelia: the ventricular zone (VZ) and rhombic lip. Signaling mechanisms that maintain the proliferative capacity of VZ resident progenitors remain elusive. We reveal that Sonic hedgehog (Shh) signaling is active in the cerebellar VZ and essential to radial glial cell proliferation and expansion of GABAergic interneurons. We demonstrate that the cerebellum is not the source of Shh that signals to the early VZ, and suggest a transventricular path for Shh ligand delivery. In agreement, we detected the presence of Shh protein in the circulating embryonic cerebrospinal fluid. This study identifies Shh as an essential proliferative signal for the cerebellar ventricular germinal zone, underscoring the potential contribution of VZ progenitors in the pathogenesis of cerebellar diseases associated with deregulated Shh signaling, and reveals a transventricular source of Shh in regulating neural development.. ...
When I left Goroka I stopped in Port Moresby, where I had the opportunity to meet Jettie and Vin Zigas. Vin had been an Australian medical officer in the highlands and was the first physician to study kuru in some detail (figure 1b). In 1957, he was joined by Gajdusek and, together, they wrote two landmark papers on the disease (Gajdusek & Zigas 1957; Zigas & Gajdusek 1957). I chose not to discuss with Vin my clinical findings indicating that kuru patients did not show signs of parkinsonism as he and Gajdusek had thought when they first described kuru. I rapidly developed a warm friendship with Vin and Jettie.. When I returned to New Guinea in 1980, I had the pleasure of meeting Michael Alpers, which marked the beginning of a long friendship. As with my first trip, my guides were Anua and Auyana. Together we saw an additional seven patients whose clinical examinations confirmed my previous impressions. Kuru was a cerebellar disease that eventually progressed to involve other parts of the central ...

Cerebellar hypoplasia The cerebellum is the portion of the brain responsible for the control of motion. When a puppy or kitten is born with an underdeveloped cerebellum, the condition is known as congenital cerebellar hypoplasia. There are infectious causes of this condition in both cats (panleukopenia infection prior to birth) and dogs (herpes virus infection prior to birth). Improper development of the cerebellum may occur due to injury, poisoning or just from an accident in development in the uterus. It is generally possible to see signs of this condition almost as soon as the puppy or kitten is born. Affected animals have tremors and unusual jerky movements or may fall down when they try to move. The symptoms do not get worse as they age. As the kitten or puppy grows it will learn to compensate for its condition but there are usually lifelong signs of a decreased ability to coordinate movement. Almost all dogs and cats with congenital cerebellar hypoplasia can live happily as pets with a ...
The first aim of this thesis was to critically appraise and improve the classification of small cerebellar infarctions and to visualise arterial cerebellar perfusion territories. Although small cerebellar infarcts are traditionally classified into "watershed" or "border zone" perfusion territories, arterial perfusion territories and the border zones in between them are widely variable among subjects. Also, many infarcts do not fit into such a classification system, which hinders its use in clinical practice [1].. We proposed two answers to these limitations. The first was to omit the traditional classification and to classify small cerebellar infarctions according to anatomical location in the cerebellum instead of arterial perfusion territories [1]. The second and more challenging answer was to develop the first imaging technique to visualise cerebellar perfusion territories in vivo [2]. This way, cerebellar infarction may be directly linked with the responsible diseased artery, for instance, ...

Human interest in the cerebellum has persisted since even the early 1500s, where Galen, Vesalius and Varolio gave the first few attempts to fully describe the macroscopic anatomy of the cerebellum. However, it was not until the late 1700s that advances were made to gain experimental evidence for the function of the cerebellum. Luigi Rolando identified a specifically motor impact after cerebellar lesions developed, as opposed to an intellectual or sensory effect. This led to the conclusion that the cerebellum incited and managed movement. Pierre Flourens and Luigi Luciani were able to use this albeit crude experimentation to further define that the cerebellum coordinated movement instead of creating it, and also to differentiate between the short-term and long-term effects of cerebellar lesions, respectively. [53] Ernesto Lugaro first defined "plasticity" as we know it in neuroscience, and also discovered the specific cells in the cerebellum that are named after him. He also furthered research ...

The Science paper gave two bits of useful information on this subject. First, they actually measured the release of cytokines by their treatment and second they have demonstrated that giving high doses of steroids does not detract from the killing ability of the bispecific antibody. In fact patients were given methylprednisolone and low molecular weight heparin during the first treatment days as prophylaxis against cytokine release problems. The side effects of the treatment were mostly well managed. One patient with a history of near fatal sepsis died after developing an infection on this treatment. Another patient with hypogammaglobulinemia had treatment discontinued because of the development of pneumonia. One patient with a history of renal insufficiency had the drug stopped because of metabolic acidosis accompanied by a seizure. Five patients had the drug stopped because of CNS-related events; two with confusion, two with cerebellar symptoms and one with the seizure already alluded to. Al ...
The GluD2 protein, encoded by GRID2, is a member of the ionotropic glutamate receptor family that mediates excitatory synaptic transmission [17]. Studies on mice have revealed that Grid2 is expressed primarily in the Purkinje cells and it is essential for the formation and organization of synapses [23, 24]. Furthermore, mice with homozygous disruption of Grid2 show ataxia and mild cerebellar hypoplasia [25]. In humans, a few studies have recently reported on GRID2 gene variants in cerebellar syndrome with variable clinical expression. Characteristic features include slowly progressive SCA, ocular symptoms including upgaze and nystagmus, hypotonia, developmental delay with cognitive decline, and reduced volume of cerebellar vermis. The symptoms have been associated with both biallelic or monoallelic mutations indicating alternate patterns of inheritance [3-7].. Our combined data show that a novel and homozygous missense variant in the GRID2 gene is associated with the clinical features in our ...

The idea is interesting, though. The cerebellar cortex is the cytoarchitecturally the most well mapped out part of the brain, due to a very stereotyped pattern. Simulations of the cerebellum have been worked on for years (I remember making a crude model on a Purkinje cell in my Comp Neuro class back in 2000), and this seems like the next logical step. While ataxia is the most notable symptom of cerebellar damage, there are distinct cognitive deficits as well. Whether these are due to the influence of cerebellum on other parts of the brain, or appears as an epiphenomenon (I cant coordinate my reaching for objects, which makes me depressed and irritable) has yet to be completely worked out ...
Comparison of Vascular Densities of The Human Cerebellum - A Pilot Study. Vascular density corresponds to metabolic demands, which increase in highly active areas of the brain. The aim of this study was to determine the surface vascular density of three equal vertical divisions of the superior and inferior cerebellar hemispheres and to correlate with the function.. The dye Araldite was injected to the carotid and vertebral arteries of four fresh adult male human brains, maintaining a constant pressure of 93 mmHg. The cerebellums were examined, and a count was made, from the number of vessels entering each square on an overlying grid, using the light microscope and the camera Lucida. The vascular density of the three vertical columns were calculated and compared. The mean values of the vascular densities of the three vertical columns were, vessels per mm2 (from medial to lateral) left superior - 1.67, 1.89, 1.54, right superior - 1.52, 1.52, 1.28, left inferior - 1.17, 1.30, 1.19, right inferior ...

Despite the significant amount of adaptation in the saccades made by the cerebellar patients, their adapted response was missing a fundamental characteristic. The control subjects exhibited robust forgetting during each set break: the vertical endpoint of control saccades suddenly decreased (Fig. 5A, first arrow). This set structure was prominent when we plotted the changes in saccade parameters with respect to the last bin (last two saccades) of each set (Fig. 5C). On average, the vertical endpoint declined by 0.43° or 26% at set start (p , 0.005, set start vs previous set end) and the peak vertical velocity declined by 5.8°/s or 14.3% (p , 0.05). By the sixth saccade after set start the vertical endpoints and velocities had recovered to the magnitude of the previous set (Fig. 5C). That is, the short break produced forgetting, and the set restart produced rapid relearning. When viewed as a group, both the forgetting and the rapid relearning were absent in the saccades of the cerebellar ...

As of March 2016, 6.36 Mb of sequence (83 genes, 1557 exons) generated in our lab was compared between Sanger and NextGen methodologies. We detected no differences between the two methods. The comparison involved 6400 total sequence variants (differences from the reference sequences). Of these, 6144 were nucleotide substitutions and 256 were insertions or deletions. About 65% of the variants were heterozygous and 35% homozygous. The insertions and deletions ranged in length from 1 to over 100 nucleotides.. In silico validation of insertions and deletions in 20 replicates of 5 genes was also performed. The validation included insertions and deletions of lengths between 1 and 100 nucleotides. Insertions tested in silico: 2200 between 1 and 5 nucleotides, 625 between 6 and 10 nucleotides, 29 between 11 and 20 nucleotides, 25 between 21 and 49 nucleotides, and 23 at or greater than 50 nucleotides, with the largest at 98 nucleotides. All insertions were detected. Deletions tested in silico: 1813 ...

The prevalence of paraneoplastic cerebellar degeneration (PCD) associated with gynecological cancer is rare. Here, we reported the first case of ovarian cancer revealed by PCD in our institute. we describe a 80- year old Moroccan female presented with subacute vestibular and cerebellar syndromes, she had an inguinal lymphadenopathy,with high levels of Anti-YO. Rapid progression and absence of known etiologies point towards a probable paraneoplastic origin of the syndrome in this patient. The exact incidence of PNS among those diagnosed with cancer remains uncertain, it is important to report this cases in the literature to help early diagnosis and appropriate treatment, which are able to stabilize the neurological symptoms.
A 51 year old man with paraneoplastic cerebellar degeneration from gastric adenocarcinoma showed cerebellar hypermetabolism and increased perfusion on brain FDG-PET scan and SPECT during the acute stage of his illness. The patient underwent subtotal gastrectomy. The intensity of the hypermetabolism had decreased markedly on follow-up FDG-PET 3 months later following two cycles of chemotherapy. We suggest that the cerebellar hypermetabolism may have been due to an acute inflammatory process associated with an immunological reaction.. ...

Methotrexate is a folate antagonist and one of several first-line disease-modifying drugs for treating rheumatoid arthritis. It can be given orally or parenterally: the bioavailability of oral doses of methotrexate is highly variable, being only two-thirds of that by parenteral use. The most frequent side effects are nausea and vomiting, and the most serious are toxicity of the bone marrow, liver, kidney and mucosa. Being hydrophilic, methotrexate barely penetrates the blood-brain barrier so that central nervous system toxicity is rare. However, this may follow intrathecal or high-dose intravenous administration, as used to treat haematological malignancies. There are a few case reports of leukoencephalopathy after low-dose oral methotrexate, involving the temporal and/or occipital lobes or the cerebellum.1 Subcutaneous administration of methotrexate seems to give a better clinical response and fewer side effects than oral methotrexate.2 Nevertheless, we recently observed a woman … ...
Background: Nephronophthisis (NPHP) is an autosomal recessive cystic kidney disease that constitutes the most common genetic cause of renal failure in the first three decades of life. Using positional cloning, six genes (NPHP1-6) have been identified as mutated in NPHP. In Joubert syndrome (JBTS), NPHP may be associated with cerebellar vermis aplasia/hypoplasia, retinal degeneration and mental retardation. In Senior-Løken syndrome (SLSN), NPHP is associated with retinal degeneration. Recently, mutations in NPHP6/CEP290 were identified as a new cause of JBTS.. Methods: Mutational analysis was performed on a worldwide cohort of 75 families with SLSN, 99 families with JBTS and 21 families with isolated nephronophthisis.. Results: Six novel and six known truncating mutations, one known missense mutation and one novel 3 bp pair in-frame deletion were identified in a total of seven families with JBTS, two families with SLSN and one family with isolated NPHP.. ...

Ocular flutter is a rare, horizontal eye movement disorder characterized by rapid saccadic oscillations. Previous reports have presented a relationship between ocular flutter syndrome and many conditions/diseases. However, it is surprising that there have been few reported cases in which there has been a clear anatomically localized lesion linked to ocular flutter. So the pathophysiological basis for ocular flutter syndrome is not understood yet. We have recently experienced a case of ocular flutter syndrome where the ocular flutter was associated with dysmetria, dysdiadochokinesia, kinetic predominant tremor, and ataxia. The prodromal symptoms, self-limited illness course and cerebrospinal fluid (CSF) pleocytosis of our case suggest an infectious aetiology for this syndrome. Although most of the sequelae of infectious diseases represent more diffuse involvement of the nervous system, the predominant cerebellar symptoms and signs associated with ocular flutter imply that the single responsible ...

N2 - Cell proliferation has been studied in the human cerebellar cortex between the 24th gestational week and the 12th postnatal month. Intensive cell formation has been found in the external granular layer (EGL) of the human cerebellum, where the highest cell proliferation rate occurs between the 28th and 34th gestational weeks. This is followed by a gradual decrease that lasts up to the eighth postnatal month. As late in development as the fifth postnatal month, still 30% of cells of the EGL are labeled with the monoclonal antibody Ki-67, which is specific for dividing cells. The width of the EGL remained unchanged from the 28th gestational week to the end of the first postnatal month, when it starts to decrease and completely disappears by the 11th postnatal month. Large number of Ki-67 labeled ...
Examining the histogram of one reconstructed slice (figure 2b), one observes that only four of the five Gaussians can be clearly related to known morphological structures of the human cerebellum. The fifth Gaussian with the largest half width describes the Δδ-values lying between the formalin and stratum moleculare related peaks. Therefore, this Gaussian basically corresponds to the partial volume between these two components. Aside from the partial volume one finds an additional peak at Δδ = 1.3 × 10−8, which appears rather as a shoulder. This shoulder becomes more obvious in the histogram of the entire three-dimensional dataset (figure 6c). The quantitative analysis of the shoulder reveals that the related Δδ-values are located in areas of the cerebellum that were in direct contact with the formalin solution during the whole fixation period. Obviously, the formalin treatment of the human cerebellum changes the electron density at the tissue periphery.. The usefulness of the ...

Learning to find the endpoint. However, patients who show defects in the vestibular system or the cerebellum have greater difficulty in controlling the direction of gaze in response to changes in their environment. "It turns out that information relayed from the balance organs to the vestibular system is essential for the optimization of gaze shifts," says Nadine Lehnen. Patients with complete bilateral vestibular loss are therefore unable to perform such shifts in the most efficient way. "In striking contrast, patients with cerebellar damage can, to a certain extent, learn to optimize certain parameters of head and eye movements, by adjusting the velocity of head movement, for instance," says Glasauer.. "These results provide the first evidence that the vestibular system is critical for optimizing voluntary movements", says Dr. Kathleen E. Cullen from McGill University in Montreal in a scientific commentary to the study appearing in the print issue of Brain. The new findings are of relevance ...

Gross et al reviewed hospital databases to identify children with CMs who had not been treated surgically and who had clinical and radiological follow-up. Annual hemorrhage rates were calculated in lesion-years, and risk factors were assessed using the Cox regression. In a cohort of 167 patients with 222 CMs, the mean patient age at the time of diagnosis was 10.1 years old (SD 6.0). Ninety patients (54%) were male. One hundred four patients (62%) presented with hemorrhage from at least 1 CM, 58 (35%) with seizures with or without CM hemorrhage, and 43 (26%) with incidental lesions. Twenty-five patients (15%) had multiple CMs, 17 (10%) had a family history of CMs, and 33 (20%) had radiologically apparent developmental venous anomaly (DVAs). The overall annual hemorrhage rate was 3.3%. Permanent neurological morbidity was 29% per hemorrhage, increasing to 45% for brainstem, thalamic, or basal ganglia CM and decreasing to 15% for supratentorial lobe or cerebellar lesions. The annual hemorrhage rate ...

Raised levels of P/Q type voltage-gated calcium-channel (VGCC) antibodies were found in 16 (41%) of 39 patients with paraneoplastic cerebellar degeneration (PCD) and Hu antibodies were found in nine (23%). Seven of the 16 VGCC antibody-positive patients had Lambert-Eaton myasthenic syndrome (LEMS). Seven of 15 CSF samples had VGCC antibodies, with evidence of intrathecal synthesis in four. VGCC antibodies should be looked for in PCD, even if there are no symptoms of LEMS, and may be related to the cerebellar dysfunction.

Clinical presentation A middle-aged patient was referred for treatment of a bilobed saccular aneurysm identified on a CT angiogram performed for a subarachnoid hemorrhage which occurred 20 days prior to presentation. A diagnostic angiogram showed a bilobed wide-necked saccular aneurysm at the AICA origin with the AICA arising from the dome of the aneurysm and also supplying the territory of the posterior inferior cerebellar artery. The therapeutic procedure involved trans-aneurysmal cannulation of the AICA with the microcatheter left in situ. Another microcatheter was maneuvered into the larger dome of the aneurysm. A stent was then deployed in the basilar artery, jailing the previous microcatheter in the aneurysm. Helical Guglielmi detachable coils were deployed in the aneurysm resulting in complete occlusion of the aneurysm with preservation of the AICA.. ...

  • There is abundant evidence for cerebellar involvement in schizophrenia, where the cerebellum has been suggested to contribute to cognitive, affective and motor dysfunction. (biomedcentral.com)
  • DCN neurons fire spontaneously in the absence of synaptic input from Purkinje neurons and modulation of the DCN response by Purkinje input is believed to be responsible for coordination of movement, while uncontrolled spontaneous firing of DCN neurons may underlay cerebellar ataxia. (clinicaltrials.gov)
  • A special emphasis is placed on causes of cerebellar ataxia, both acquired and genetic, that are reversible when timely therapy is initiated. (uptodate.com)
  • Purkinje cells project inhibitory signals to the deep cerebellar nuclei(DCN) which have a critical role in cerebellar function and motor performance. (clinicaltrials.gov)
  • Loss of brain cells in the cerebellum causes movement problems characteristic of the disease, but it is unclear how this cell loss is related to the impaired function of Purkinje cells. (ivami.com)
