The use of atypical antipsychotics in the management of schizophrenia. (1/321)
Long-term drug treatment of schizophrenia with conventional antipsychotics has limitations: an estimated quarter to one third of patients are treatment-resistant; conventional antipsychotics have only a modest impact upon negative symptoms (poverty of thought, social withdrawal and loss of affect); and adverse effects, particularly extrapyramidal symptoms (EPS). Newer, so-called atypical, antipsychotics such as olanzapine, risperidone, sertindole and clozapine (an old drug which was re-introduced in 1990) are claimed to address these limitations. Atypical agents are, at a minimum, at least as effective as conventional drugs such as haloperidol. They also cause substantially fewer extrapyramidal symptoms. However, some other adverse effects are more common than with conventional drugs. For example, clozapine carries a significant risk of serious blood disorders, for which special monitoring is mandatory; it also causes troublesome drowsiness and increased salivation more often than conventional agents. Some atypical agents cause more weight gain or QT prolongation than older agents. The choice of therapy is, therefore, not straightforward. At present, atypical agents represent an advance for patients with severe or intolerable EPS. Most published evidence exists to support the use of clozapine, which has also been shown to be effective in schizophrenia refractory to conventional agents. However, the need for compliance with blood count monitoring and its sedative properties make careful patient selection important. The extent of any additional direct benefit offered by atypical agents on negative symptoms is not yet clear. The lack of a depot formulation for atypical drugs may pose a significant practical problem. To date, only two double-blind studies in which atypical agents were compared directly have been published. Neither provides compelling evidence for the choice of one agent over another. Atypical agents are many times more expensive than conventional drugs. Although drug treatment constitutes only a small proportion of the costs of managing schizophrenia, the additional annual cost of the use of atypical agents in, say, a quarter of the likely U.K. schizophrenic population would be about 56 M pound sterling. There is only limited evidence of cost-effectiveness. Atypical antipsychotics are not currently licensed for other conditions where conventional antipsychotics are commonly used, such as behaviour disturbance or dementia in the elderly. Their dose, and place in treatment in such cases have yet to be determined. (+info)Bilateral basal ganglial necrosis after allogeneic bone marrow transplantation in a child with Kostmann syndrome. (2/321)
A 6-year-old girl underwent allogeneic BMT from a matched sibling donor for the treatment of Kostmann syndrome. She suddenly became drowsy on day 30 after BMT, and lost consciousness 2 days later. Cranial CT scan showed symmetrical lesions suggesting bilateral necrosis in the basal ganglia. Clinical and laboratory investigations failed to reveal any evidence of neurometabolic disease. (+info)Non-typhoid Salmonella meningitis complicated by a infarction of basal ganglia. (3/321)
A previously healthy 16-month-old Korean girl with symptoms of fever, vomiting, and generalized tonic seizure was diagnosed to have Group D non-typhoid Salmonella meningitis. The patient was treated with ceftriaxone (100 mg/kg/day) and amikin (22.5 mg/kg/day) initially and ciprofloxacin (30 mg/kg/day) was added later because of clinical deterioration and disseminated intravascular coagulation. Brain CT performed on the second day showed a well-demarcated low density lesion in the right lentiform nucleus and both caudate nuclei, without evidence of increased intracranial pressure. MRI performed on the 11th day confirmed CT scan findings as well as right subdural fluid collection, brain atrophy, and ventriculomegaly. She underwent subdural drainage and later ventriculo-peritoneal shunt operation. Despite receiving intensive treatment, she still has severe neurologic sequelae. Our case shows that infarctions of basal ganglia and thalami are not specific for tuberculous meningitis and that meningitis complicated by infarction is indicative of grave prognosis. (+info)Identification of a locus on chromosome 14q for idiopathic basal ganglia calcification (Fahr disease). (4/321)
Idiopathic basal ganglia calcification (IBGC) is a neurodegenerative syndrome that is associated with a variety of movement disorders and neurobehavioral and cognitive manifestations. Despite numerous clinical, pathological, and biochemical investigations, its etiology remains unknown. We have identified a multigenerational family with dominantly inherited IBGC and, in 24 members of this family, performed a whole-genome scan using polymorphic microsatellite markers to identify the first chromosomal locus for this disorder (IBGC1). A maximum two-point LOD score of 3.37 was obtained at marker D14S1014, and a maximum multipoint LOD score of 4.95 was obtained between D14S75 and D14S306. The minimal haplotype shared by affected patients extended over a 17.1-cM region bounded by D14S70 and D14S66, which is potentially further narrowed to a 13.3-cM region by a recombination observed in a patient with probable affected status. The age at onset appeared to be decreasing by an average of >20 years with each transmission, which is consistent with genetic anticipation. (+info)Dyspraxia in a patient with corticobasal degeneration: the role of visual and tactile inputs to action. (5/321)
OBJECTIVES: To investigate the roles of visual and tactile information in a dyspraxic patient with corticobasal degeneration (CBD) who showed dramatic facilitation in miming the use of a tool or object when he was given a tool to manipulate; and to study the nature of the praxic and neuropsychological deficits in CBD. METHODS: The subject had clinically diagnosed CBD, and exhibited alien limb behaviour and striking ideomotor dyspraxia. General neuropsychological evaluation focused on constructional and visuospatial abilities, calculation, verbal fluency, episodic and semantic memory, plus spelling and writing because impairments in this domain were presenting complaints. Four experiments assessed the roles of visual and tactile information in the facilitation of motor performance by tools. Experiment 1 evaluated the patient's performance of six limb transitive actions under six conditions: (1) after he described the relevant tool from memory, (2) after he was shown a line drawing of the tool, (3) after he was shown a real exemplar of the tool, (4) after he watched the experimenter perform the action, (5) while he was holding the tool, and (6) immediately after he had performed the action with the tool but with the tool removed from his grasp. Experiment 2 evaluated the use of the same six tools when the patient had tactile but no visual information (while he was blindfolded). Experiments 3 and 4 assessed performance of actions appropriate to the same six tools when the patient had either neutral or inappropriate tactile feedback-that is, while he was holding a non-tool object or a different tool. RESULTS: Miming of tool use was not facilitated by visual input; moreover, lack of visual information in the blindfolded condition did not reduce performance. The principal positive finding was a dramatic facilitation of the patient's ability to demonstrate object use when he was holding either the appropriate tool or a neutral object. Tools inappropriate to the requested action produced involuntary performance of the stimulus relevant action. CONCLUSIONS: Tactile stimulation was paramount in the facilitation of motor performance in tool use by this patient with CBD. This outcome suggests that tactile information should be included in models which hypothesise modality specific inputs to the action production system. Significant impairments in spelling and letter production that have not previously been reported in CBD have also been documented. (+info)Progressive frontal gait disturbance with atypical Alzheimer's disease and corticobasal degeneration. (6/321)
OBJECTIVES: The clinical neuropsychological, neuroradiological, and neuropathological description of two patients presenting with a frontal gait disturbance. METHODS: Clinical case note review, neuropsychological assessment, functional imaging with (15)O(2) and (18)F-fluorodopa PET, and neuropathology. RESULTS: Both patients presented with frontal gait impairment and only later developed more widespread cognitive impairment. In both cases (15)O(2) PET disclosed focal hypometabolism in the medial frontal lobes and in one patient (18)F-fluorodopa uptake into the caudate and putamen was normal. The neuropathological examination in one patient showed Alzheimer's histopathology together with large swollen eosinophilic neurons characteristic of corticobasal degeneration, which were particularly prominent in the medial frontal lobes. CONCLUSION: Focal degeneration of the medial frontal lobes may present as an isolated gait disturbance and should be considered in the differential diagnosis of patients who present without an obvious structural abnormality on neuroimaging. (+info)Extrapyramidal type rigidity in rheumatoid arthritis. (7/321)
OBJECTIVES: We had noted cogwheel rigidity in a number of patients with rheumatoid arthritis (RA). Based on this finding, we aimed to investigate formally the presence of rigidity and cogwheeling in RA patients. Our secondary aim was to survey the co-existence of RA and Parkinson's disease (PD). METHODS: A total of 87 consecutive patients with a diagnosis of RA, 78 patients with PD and 67 otherwise healthy patients attending a dedicated headache clinic participated in the study. RESULTS: Rigidity was observed in 24% of RA, 60% of PD and 2% of headache patients. The frequency among the RA patients was significantly higher compared to that of patients with headache (chi 2 = 15.2; P = 0.00009). The frequency of PD among the RA patients was 2/87 (2.3%), while the frequency of RA among the PD patients was 6/78 (7.7%). CONCLUSION: Rigidity can be observed in approximately a quarter of patients with RA. (+info)Enhanced association of mutant triosephosphate isomerase to red cell membranes and to brain microtubules. (8/321)
In a Hungarian family with triosephosphate isomerase (TPI; D-glyceraldehyde-3-phosphate keto-isomerase, EC 5.3.1.1) deficiency, two germ-line identical, but phenotypically differing compound heterozygote brothers (one of them with neurological disorder) have been identified with the same very low (<5%) TPI activity and 20- or 40-fold higher erythrocyte dihydroxyacetone phosphate levels as compared with normal controls. Our present studies with purified TPI and hemolysates revealed the binding of TPI, and the binding of human wild-type and mutant TPIs in hemolysate, to the red cell membrane, and the interference of binding with other hemolysate proteins. The binding of the mutant TPI is enhanced as compared with the wild-type enzyme. The increased binding is influenced by both the altered structure of the mutant and the changes in the red cell membrane. Compared with binding of glyceraldehyde-3-phosphate dehydrogenase, the isomerase binding is much less sensitive to ionic strength or blocking of the N-terminal tail of the band-3 transmembrane protein. The binding of TPIs to the membrane decreases the isomerase activity, resulting in extremely high dihydroxyacetone phosphate levels in deficient cells. In cell-free brain extract, tubulin copolymerizes with TPI and with other cytosolic proteins forming highly decorated microtubules as shown by immunoblot analysis with anti-TPI antibody and by electron microscopic images. The efficacy order of TPI binding to microtubules is propositus > brother without neurological disorder > normal control. This distinct microcompartmentation of mutant proteins may be relevant in the development of the neurodegenerative process in TPI deficiency and in other, more common neurological diseases. (+info)Some examples of basal ganglia diseases include:
1. Parkinson's disease: A neurodegenerative disorder characterized by tremors, rigidity, bradykinesia (slow movement), and postural instability.
2. Huntington's disease: An autosomal dominant disorder that causes progressive degeneration of the basal ganglia and a decline in cognitive, motor, and psychiatric functions.

These conditions are often challenging to diagnose and manage, and may require a comprehensive evaluation by a multidisciplinary team of healthcare professionals, including neurologists, psychiatrists, geneticists, and other specialists. Early diagnosis and appropriate treatment can help improve outcomes for individuals with these conditions.
Symptoms:
* Rapidly progressive dementia
* Ataxia (loss of coordination and balance)
* Myoclonus (involuntary muscle jerks)
* Visual disturbances
* Cognitive decline
Diagnosis:
* Clinical evaluation
* Neuroimaging studies (MRI, CT scans)
* Electroencephalography (EEG)
* Cerebrospinal fluid (CSF) examination
Treatment and Management:
* There is no cure for CJD, but various medications can be used to manage the symptoms.
* Palliative care is essential to alleviate suffering and improve quality of life.
* Supportive care includes physical therapy, speech therapy, and occupational therapy.
Prognosis:
* CJD is a rapidly progressive disease with a poor prognosis, typically leading to death within 1-2 years after onset of symptoms.
Causes and Risk Factors:
* The cause of CJD is the transmission of misfolded prions, which are infectious proteins that accumulate in the brain.
* The most common form of transmission is through medical procedures using contaminated tissue, such as corneal transplants or dura mater grafts.
* There is also a rare genetic form of CJD, which is inherited from one's parents.
Complications:
* CJD can lead to various complications, including pneumonia, seizures, and coma.
* The disease can also cause psychiatric symptoms such as depression, anxiety, and hallucinations.
In conclusion, Creutzfeldt-Jakob Syndrome is a rare and fatal brain disorder characterized by rapid neurological deterioration, prion accumulation in the brain, and poor prognosis. It is important to be aware of the causes and risk factors of CJD, as well as its symptoms and complications, to provide appropriate diagnosis and treatment for affected individuals.
The Fore people traditionally practiced cannibalism, consuming the brains of their deceased relatives as part of their funeral rites. This practice allowed the transmission of the misfolded protein from one individual to another, leading to an outbreak of kuru in the 1950s and 1960s. The disorder was first identified by medical professionals in the early 20th century, and it has since been studied extensively by neurologists and anthropologists.
Kuru is a unique example of a transmitted neurodegenerative disorder that is caused by a misfolded protein. It has contributed significantly to our understanding of the mechanisms underlying such disorders, and it has also highlighted the importance of cultural practices in shaping human health and disease.
The study of kuru has led to several important findings and advancements in the field of neurology. For example, researchers have identified the specific misfolded protein responsible for the disorder, and they have developed techniques for detecting and quantifying this protein in the brain and other tissues. Additionally, studies of kuru have shed light on the role of prions in transmitting infectious proteins, and they have provided insights into the mechanisms underlying other neurodegenerative disorders such as Creutzfeldt-Jakob disease and bovine spongiform encephalopathy (BSE).
Kuru is a rare and degenerative neurological disorder that is caused by the transmission of a misfolded protein called PrPSc. The disorder is transmitted through cannibalism, specifically the consumption of infected human tissue, and it is primarily found among the Fore people of Papua New Guinea. Kuru has contributed significantly to our understanding of prion diseases and their mechanisms, and it has also highlighted the importance of cultural practices in shaping human health and disease.
The study of kuru has been ongoing for several decades, and researchers have made significant progress in understanding the disorder's causes and transmission. One of the key findings has been the identification of PrPSc as the infectious agent responsible for kuru. This protein is a misfolded form of the normal prion protein (PrPC), which is found throughout the body. When PrPC is misfolded into PrPSc, it becomes resistant to degradation and can accumulate in the brain and other tissues, leading to the degenerative effects of kuru.
Researchers have also developed several techniques for detecting and quantifying PrPSc in the brain and other tissues. One of these techniques is called immunohistochemistry, which involves using antibodies to detect specific proteins in tissue samples. Another technique is called western blotting, which involves separating proteins by size and then probing them with antibodies to identify specific proteins. These techniques have been used to study the distribution and abundance of PrPSc in the brains of kuru patients, and they have shown that PrPSc is present throughout the brain, but is particularly concentrated in certain areas such as the cerebellum and brainstem.
In addition to understanding the causes of kuru, researchers have also made significant progress in understanding its transmission. Kuru is believed to be transmitted through a process called "protein misfolding cyclic amplification," which involves the conversion of normal PrPC into PrPSc. This process can occur through several mechanisms, including direct contact between individuals, or through the consumption of contaminated tissue.
One of the key cultural practices that has been linked to the transmission of kuru is the practice of "kuru feasting," in which family members consume the brains and other tissues of deceased loved ones as a way of honoring their memory. This practice was common among the Fore people of Papua New Guinea, who were one of the groups most affected by kuru. Researchers have found that kuru feasting can significantly increase the risk of transmission, and it is thought to be an important factor in the spread of the disease.
In addition to understanding the causes and transmission of kuru, researchers have also made significant progress in developing potential treatments for the disease. One promising approach is the use of antiviral drugs, which have been shown to reduce the levels of PrPSc in the brains of infected individuals. Another approach is the use of immunotherapy, which involves stimulating the body's immune system to attack and remove PrPSc-infected cells.
Overall, research into kuru has made significant progress in understanding its causes, transmission, and potential treatments. While much work remains to be done, this research has the potential to improve our understanding of other transmissible spongiform encephalopathies, such as Creutzfeldt-Jakob disease, and could ultimately lead to new treatments for these devastating diseases.
Symptoms of BSE include:
* Behavioral changes, such as aggression or confusion
* Loss of coordination and balance
* Weakness or paralysis of the limbs
* Vision problems
* Difficulty swallowing or chewing
* Change in vocalization or bellowing
BSE is transmitted through the consumption of contaminated beef products, such as meat and bonemeal, which contain the abnormal prion protein. The disease can also be spread through blood transfusions or other medical procedures using infected material.
There is no cure for BSE, and it is typically diagnosed through a combination of clinical signs, necropsy, and laboratory tests such as the polymerase chain reaction (PCR) or Western blotting.
Prevention of BSE includes:
* Implementing strict controls on the handling and disposal of animal carcasses and tissues
* Avoiding the use of meat and bonemeal in animal feed
* Ensuring proper sterilization and safety protocols in medical procedures
* Monitoring and testing for the presence of the disease in cattle populations.
BSE has significant economic and public health implications, as it can lead to the loss of entire herds and the closure of livestock markets, as well as the potential for human transmission through the consumption of contaminated beef products.
