Agnosia: Loss of the ability to comprehend the meaning or recognize the importance of various forms of stimulation that cannot be attributed to impairment of a primary sensory modality. Tactile agnosia is characterized by an inability to perceive the shape and nature of an object by touch alone, despite unimpaired sensation to light touch, position, and other primary sensory modalities.Gerstmann Syndrome: A disorder of cognition characterized by the tetrad of finger agnosia, dysgraphia, DYSCALCULIA, and right-left disorientation. The syndrome may be developmental or acquired. Acquired Gerstmann syndrome is associated with lesions in the dominant (usually left) PARIETAL LOBE which involve the angular gyrus or subjacent white matter.

Memories are made of this: the effects of time on stored visual knowledge in a case of visual agnosia. (1/133)

We report the effects of the passage of time on the longterm visual knowledge for objects in a patient with visual agnosia (H.J.A.). The naming of real objects was found to have improved, although this was not associated with any change in H.J.A.'s basic perceptual abilities which were stable over a 16-year period. The improvement in object naming was attributed to better use of non-contour-based visual information (such as surface detail and depth cues). In addition, we demonstrate a deterioration in H.J.A.'s long-term memory for the visual properties of objects, and argue that this has occurred as a result of his having impaired perceptual input. The deterioration was only apparent in drawing from memory and in the verbal descriptions of items; with forced-choice testing, H.J.A. operated at ceiling; we propose that current tests of visual imagery may not be sufficiently sensitive to detect subtle impairments of visual memory. Our findings can be taken to indicate that perceptual and memorial processes are not functionally independent, but are linked in an interactive manner.  (+info)

Topographical disorientation: a synthesis and taxonomy. (2/133)

Over the last century, several dozen case reports have presented 'topographically disoriented' patients who, in some cases, appear to have selectively lost their ability to find their way within large-scale, locomotor environments. A review is offered here that has as its aim the creation of a taxonomy that accurately reflects the behavioural impairments and neuroanatomical findings of this literature. This effort is guided by an appreciation of the models of normative way-finding offered by environmental psychology and recent neuroscience research. It is proposed that several varieties of topographical disorientation exist, resulting from damage to distinct neuroanatomical areas. The particular pattern of impairments that patients evidence is argued to be consonant with the known functions of these cortical regions and with recent neuroimaging results. The conflicting claims of previous reviews of this area are also considered and addressed.  (+info)

Unconscious letter discrimination is enhanced by association with conscious color perception in visual form agnosia. (3/133)

Adaptive behavior guided by unconscious visual cues occurs in patients with various kinds of brain damage as well as in normal observers, all of whom can process visual information of which they are fully unaware [1] [2] [3] [4] [5] [6] [7] [8]. Little is known on the possibility that unconscious vision is influenced by visual cues that have access to consciousness [9]. Here we report a 'blind' letter discrimination induced through a semantic interaction with conscious color processing in a patient who is agnosic for visual shapes, but has normal color vision and visual imagery. In seeing the initial letters of color names printed in different colors, it is normally easier to name the print color when it is congruent with the initial letter of the color name than when it is not [10]. The patient could discriminate the initial letters of the words 'red' and 'green' printed in the corresponding colors significantly above chance but without any conscious accompaniment, whereas he performed at chance with the reverse color-letter mapping as well as in standard tests of letter reading. We suggest that the consciously perceived colors activated a representation of the corresponding word names and their component letters, which in turn brought out a partially successful, unconscious processing of visual inputs corresponding to the activated letter representations.  (+info)

Receptive amusia: evidence for cross-hemispheric neural networks underlying music processing strategies. (4/133)

Perceptual musical functions were investigated in patients suffering from unilateral cerebrovascular cortical lesions. Using MIDI (Musical Instrument Digital Interface) technique, a standardized short test battery was established that covers local (analytical) as well as global perceptual mechanisms. These represent the principal cognitive strategies in melodic and temporal musical information processing (local, interval and rhythm; global, contour and metre). Of the participating brain-damaged patients, a total of 69% presented with post-lesional impairments in music perception. Left-hemisphere-damaged patients showed significant deficits in the discrimination of local as well as global structures in both melodic and temporal information processing. Right-hemisphere-damaged patients also revealed an overall impairment of music perception, reaching significance in the temporal conditions. Detailed analysis outlined a hierarchical organization, with an initial right-hemisphere recognition of contour and metre followed by identification of interval and rhythm via left-hemisphere subsystems. Patterns of dissociated and associated melodic and temporal deficits indicate autonomous, yet partially integrated neural subsystems underlying the processing of melodic and temporal stimuli. In conclusion, these data contradict a strong hemispheric specificity for music perception, but indicate cross-hemisphere, fragmented neural substrates underlying local and global musical information processing in the melodic and temporal dimensions. Due to the diverse profiles of neuropsychological deficits revealed in earlier investigations as well as in this study, individual aspects of musicality and musical behaviour very likely contribute to the definite formation of these widely distributed neural networks.  (+info)

Illusory limb movements in anosognosia for hemiplegia. (5/133)

To clarify the relation between anosognosia for hemiplegia and confabulation, 11 patients with acute right cerebral infarctions and left upper limb hemiparesis were assessed for anosognosia for hemiplegia, illusory limb movements (ILMs), hemispatial neglect, asomatognosia, and cognitive impairment. Five of 11 patients had unequivocal confabulation as evidenced by ILMs. The presence of ILMs was associated with the degree of anosognosia (p = 0.002), with hemispatial neglect (p<0.05), and with asomatognosia (p<0.01). The results confirm that a strong relation exists between anosognosia for hemiplegia and confabulations concerning the movement of the plegic limb. There is also a strong relation between ILMs and asomatognosia.  (+info)

Hemianopic colour blindness. (6/133)

A man developed cortical blindness after cerebral infarction in the distribution of both posterior cerebral arteries. When he recovered from this condition, he was found to be colour blind in the left visual field, but not in the right. This unusual situation resulted in apparently contradictory performances on hemifield and free-field tasks of colour discrimination, naming, and recognition. The contradictions may be explained by interhemispheric competition between a hemisphere which could discriminate colours and a hemisphere which was colour blind.  (+info)

Patterns of music agnosia associated with middle cerebral artery infarcts. (7/133)

The objective of the study is to evaluate if the rupture of an aneurysm located on the middle cerebral artery (MCA) results in disorders of music recognition. To this aim, 20 patients having undergone brain surgery for the clipping of a unilateral left (LBS), right (RBS) or bilateral (BBS) aneurysm(s) of the MCA and 20 neurologically intact control subjects (NC) were evaluated with a series of tests assessing most of the abilities involved in music recognition. In general, the study shows that a ruptured aneurysm on the MCA that is repaired by brain surgery is very likely to produce deficits in the auditory processing of music. The incidence of such a deficit was not only very high but also selective. The results show that the LBS group was more impaired than the NC group in all three tasks involving musical long-term memory. The study also uncovered two new cases of apperceptive agnosia for music. These two patients (N.R. and R.C.) were diagnosed as such because both exhibit a clear deficit in each of the three music memory tasks and both are impaired in all discrimination tests involving musical perception. Interestingly, the lesions overlap in the right superior temporal lobe and in the right insula, making the two new cases very similar to an earlier case report. Altogether, the results are also consistent with the view that apperceptive agnosia results from damage to right hemispheric structures while associative agnosia results from damage to the left hemisphere.  (+info)

Time-dependent activation of parieto-frontal networks for directing attention to tactile space. A study with paired transcranial magnetic stimulation pulses in right-brain-damaged patients with extinction. (8/133)

Tactile extinction has been interpreted as an attentional disorder, closely related to hemineglect, due to hyperactivation of the unaffected hemisphere, resulting in an ipsilesional attentional bias. Paired transcranial magnetic stimulation (TMS) techniques, with a subthreshold conditioning stimulus (CS) followed at various interstimulus intervals (ISIs) by a suprathreshold test stimulus (TS), are useful for investigating intracortical inhibition and facilitation in the human motor cortex. In the present work, we investigated the effects of paired TMS over the posterior parietal and frontal cortex of the unaffected hemisphere in a group of eight right-brain-damaged patients with tactile extinction who were carrying out a bimanual tactile discrimination task. The aim of the study was to verify if paired TMS could induce selective inhibition or facilitation of the unaffected hemisphere depending on the ISI, resulting, respectively, in an improvement and a worsening of contralesional extinction. In addition, we wanted to investigate if the effects of parietal and frontal TMS on contralesional extinction appeared at different intervals, suggesting time-dependent activation in the cortical network for the processing of tactile spatial information. Paired TMS stimuli with a CS and a TS, separated by two ISIs of 1 and 10 ms, were applied over the left parietal and frontal cortex after various intervals from the presentation of bimanual cutaneous stimuli. Single-test parietal TMS stimuli improved the patients' performance, whereas paired TMS had distinct effects depending on the ISI: at ISI = 1 ms the improvement in extinction was greater than that induced by single-pulse TMS; at ISI = 10 ms we observed worsening of extinction, with complete reversal of the effects of single-pulse TMS. Compared with TMS delivered over the frontal cortex, parietal TMS improved the extinction rate in a time window that began earlier. These findings shed further light on the mechanism of tactile extinction, suggesting relative hyperexcitability of the parieto-frontal network in the unaffected hemisphere, which is amenable to study and modulation by paired TMS pulses. In addition, the results show time-dependent processing of tactile spatial information in the parietal and frontal cortices, with a bimodal distribution of activity, at least in the attentional network of the unaffected hemisphere.  (+info)

Agnosia is a rare neurological condition in which an individual may face difficulty to recognize a familiar person, sound or object. It is due to occurrence of lesions in the brain. Medical conditions such as dementia, stroke, head injury or any other neurological condition may lead to development of agnosia. Moreover, there are several conditions that may cause brain lesions and are associated with agnosia.. People suffering from agnosia can still interact with others normally. As such agnosia affects a single pathway when brain suffers a certain damage. The pathway might connect primary sensory areas that store information and knowledge. The primary sensory regions mainly include visual or auditory cortices. According to the World Health Organization (WHO) estimates, neurological disorders are responsible for 4.5%-11% of all illnesses including low or high income economies.. Brain imaging techniques such as CT or MRI with or without angiographic protocols is required to characterize a central ...

The area of the brain responsible of visuospatial processing data and more specifically the orientation of an object or image is located in parietal lobe, especially on the right side. A dysfunction of this region would result in a disorder of recognition of the orientation of objects and images that the investigators call orientation agnosia. Several isolated cases are reported in the literature but to the investigators knowledge deficit has never been systematically searched, or put into perspective compared to other neuropsychological deficits. Moreover, the precise location of the lesion responsible for such a disorder remains uncertain. The objectives of this study are (1) detect the existence of orientation agnosia in case of right parietal lesion, and (2) to improve the understanding of such a deficit allowing better management of this disorder ...
A single case study of a patient with visual associative agnosia is described. The patient had well preserved language, spatial, visual, and perceptual abilities but nevertheless was impaired in recognising visually presented common objects. It is argued that his deficit cannot be accounted for in terms of a disconnection syndrome. Behavioural and anatomical (MRI scan) evidence for focal unilateral dysfunction is presented. It is concluded that the left hemisphere plays a crucial role in recognising the meaning of common objects.. ...
Agnosia (a-gnosis, non-knowledge) is a loss of ability to recognize objects, persons, sounds, shapes or smells while the specific sense is not defective nor is there any significant memory loss. It is usually associated with brain injury or neurological illness, particularly after damage to the temporal lobe.

The introduction of acetylcholinesterase inhibitor therapy for AD has demonstrated for the first time that the progression of this fatal disease can be affected, albeit temporarily.11 As treatments become more powerful and effective it will become increasingly important to make an early and accurate diagnosis in the earliest stages of cognitive impairment.. Several groups have reported posterior cortical atrophy-either bi-parietal and/or occipito-temporal involvement-as a presentation in AD. An informative study noted that patients with the bi-parietal variant present with visuo-spatial problems-that is, agraphia and dyspraxia- which may progress to Balints syndrome (visual disorientation, optic apraxia, and simultanagnosia) whereas patients with the occipito-temporal variant, the visual variant of AD, present with complaints of visual distortion, difficulty with object recognition, topographical agnosia, and alexia.12 Histopathological material is becoming available in an accruing number of ...
Posterior cortical atrophy is a syndromic diagnosis. It is characterised by progressive impairment of higher (cortical) visual function with imaging evidence of degeneration affecting the occipital, parietal and posterior temporal lobes bilaterally. Most caseswill prove to have Alzheimer pathology. The aim of this review is to summarise the development of the concept of this disorder since it was first introduced. A critical discussion of the evolving diagnostic criteria is presented and the differential diagnosis with regard to the underlying pathology is reviewed. Emphasis is given to the visual dysfunction that defines the disorder, and the classical deficits, such as simultanagnosia and visual agnosia, as well as the more recently recognised visual field defects, are reviewed, along with the evidence on their neural correlates. The latest developments on the imaging of PCA are summarised, with special attention to its role on the differential diagnosis with related conditions.

methods used to decompose neuroanatomy of visuospatial disorders. The first study contrasted the neural substrates of different neglect symptoms, specifically the contributions of common and dissociable grey and white matter changes linked to allocentric and egocentric neglect. Two following studies decomposed the neuroanatomy of frequently co-occurring spatial attention syndromes by examining (1) the lesion patterns associated with visual and tactile extinction vs. those related to visual field defects and neglect, and (2) the lesion pattern linked to simultanagnosia, extracting out lesions associated with unilateral visuospatial deficits. These studies demonstrated that the different patterns of grey matter lesions in individual patients, and the laterality of white matter disconnections, determine the degree to which visual processing and spatial attention are disrupted and thus the nature of the observed cognitive symptoms. The final study examined the neuroanatomy of subacute relative to ...
Relatively little has been discovered about the cause of the condition since its initial identification. Recent studies from the empirical data are prone to consider anosognosia a multi-componential syndrome or multi-faceted phenomenon. That is it can be manifested by failure to be aware of a number of specific deficits, including motor (hemiplegia), sensory (hemianaesthesia, hemianopia), spatial (unilateral neglect), memory (dementia), and language (receptive aphasia) due to impairment of anatomo-functionally discrete monitoring systems.[2][3]. Anosognosia is relatively common following different causes of brain injury, such as stroke and traumatic brain injury; for example, anosognosia for hemiparesis, (weakness of one side of the body) with onset of acute stroke is estimated at between 10% and 18%.[6] However, it can appear to occur in conjunction with virtually any neurological impairment. It is more frequent in the acute than in the chronic phase and more prominent for assessment in the ...

Bálints syndrome is an uncommon and incompletely understood triad of severe neuropsychological impairments: inability to perceive the visual field as a whole (simultanagnosia), difficulty in fixating the eyes (oculomotor apraxia), and inability to move the hand to a specific object by using vision (optic ataxia). It was named in 1909 for the Austro-Hungarian neurologist and psychiatrist Rezső Bálint who first identified it. Bálints syndrome occurs most often with an acute onset as a consequence of two or more strokes at more or less the same place in each hemisphere. Therefore, it occurs rarely. The most frequent cause of complete Bálints syndrome is said by some to be sudden and severe hypotension, resulting in bilateral borderzone infarction in the occipito-parietal region. More rarely, cases of progressive Bálints syndrome have been found in degenerative disorders such as Alzheimers disease or certain other traumatic brain injuries at the border of the parietal and the occipital ...
Attention: Temporal Dynamics After Stroke Attention deficits (neglect, extinction, simultanagnosia) are at the core of behavioural impairments occurring after stroke. Our understanding of the neural underpinnings of such disorders remains primarily rooted in neuropsychological studies relying on anatomical characterisations of brain deficits. The few studies of functional brain activity have relied mainly on methods lacking the temporal resolution to chart changes in the modulatory dynamics that are essential to the operation of attention. Members of the Brain & Cognition Lab have begun investigating how the temporal dynamics of visual attention are altered by focal brain lesions by combining non-invasive methods with high temporal resolution (MEG and EEG) with methods with high spatial resolution (fMRI) and psychophysical methods. The studies will shed light on the neuronal signatures of attention deficits commonly observed in stroke survivors.. Experimental Approach. We are using novel tasks ...

MalaCards based summary : Verbal Auditory Agnosia is related to landau-kleffner syndrome and auditory agnosia. An important gene associated with Verbal Auditory Agnosia is GRIN2A (Glutamate Ionotropic Receptor NMDA Type Subunit 2A), and among its related pathways/superpathways is Nicotine addiction. Affiliated tissues include brain, temporal lobe and cortex ...
In the somatosensory system, it is well known that the bilateral secondary somatosensory cortex (SII) receives projections from the unilateral primary somatosensory cortex (SI), and the SII cortex, in turn, sends feedback projections to SI. Most neuroimaging studies have clearly shown bilateral SII activation using only unilateral stimulation for both anatomical and functional connectivity across SII subregions. However, no study has unveiled differences in the functional connectivity of the contra- and ipsilateral SII network that relate to frontoparietal areas during tactile object recognition. Therefore, we used event-related functional magnetic resonance imaging (fMRI) and a delayed match-to-sample (DMS) task to investigate the contributions of bilateral SII during tactile object recognition. In the fMRI experiment, fourteen healthy subjects were presented with tactile angle stimuli on their right index finger and asked to encode three sample stimuli during the encoding phase and one test stimulus
... is a rare neurological disorder characterised by the inability to recognise faces. Prosopagnosia is also known as face blindness or facial agnosia. The term prosopagnosia comes from the Greek words for "face" and "lack of knowledge." Depending upon the degree of impairment, some people with prosopagnosia may only have difficulty recognising a familiar face; others will be unable to discriminate between unknown faces, while still others may not even be able to distinguish a face as being different from an object. Some people with the disorder are unable to recognise their own face. Prosopagnosia is not related to memory dysfunction, memory loss, impaired vision, or learning disabilities. Prosopagnosia is thought to be the result of abnormalities, damage, or impairment in the right fusiform gyrus, a fold in the brain that appears to coordinate the neural systems that control facial perception and memory. Prosopagnosia can result from stroke, traumatic brain injury, or certain ...

It depends on the severity of both. A very severely learning-disabled reader must be explicitly taught to blend in a time-intensive and deliberate manner (a la Teach You Child to Read in 10 Minutes a Day, which is meant for the very young but works well with LDs). A very severely LD math student must be taught number-ness and one-to-one correspondence in a very deliberate and time-intensive manner. Neither of these things are true of vast majority of math OR reading students. And some, a very few, kids will never be able to recognize numbers or letters though they are not so low-IQ that they cant because of a visual agnosia that cant be treated. ...

When I visit my wife in hospital, she talks about me and about things we did together, as if she were talking to someone else about me. It saddens me, but at the same time I realise that she hasnt forgotten me at all. She still cares for me a lot, but she just doesnt recognise me.. If the person you are caring for sometimes has difficulty recognising who people are and what objects are, you may be inclined to put it down to memory loss, confusion or faulty eyesight. In some cases, you may be right. However, there is another possibility. It could be due to the fact that the brain of the person with dementia cannot put together and make sense of what they remember and what they can see. Information from these two sources no longer tallies. This problem is sometimes referred to as "agnosia". The consequences of this problem are that someone may fail to recognise people and use objects inappropriately. This can make life very difficult for the person and increase isolation and fear in that ...

Why are we prone to make mistakes in light of misleading information, even when accurate information is right there in front of us?. Demonstration #1. Before we get started on addressing this question, I would like to you to try to answer another very straightforward question: Are there more words in the English language that begin with the letter r or have r as their third letter?. The answer, as some, though likely not all, may have guessed (without reading ahead, of course!) was that there are more words that have r as the third letter. In reality, there are nearly twice as many words that have the letter r in the third position as opposed to the first position by some estimates. Most people guess that there are more words that begin with r because such words are easier to generate; however, there are apparently many more words that have r as the third letter (see Tversky and Kahneman, 1973). To name a few as examples: car, bird, warm, xerox, etc.. But why does this seem so counterintuitive? ...

Klüver-Bucy syndrome is a syndrome resulting from bilateral lesions of the medial temporal lobe (including amygdaloid nucleus). Klüver-Bucy syndrome may present with compulsive eating, hypersexuality, insertion of inappropriate objects in the mouth (hyperorality), visual agnosia, and docility. The list of symptoms differs somewhat by source. Generally included are the following: Amnesia. Characterised by an inability to recall memories. Its nature is both anterograde and retrograde, meaning new memories cannot be formed and old memories cannot be recalled. The level of amnesia is considered to be profound. Docility. Characterized by exhibiting diminished fear responses or reacting with unusually low aggression. This has also been termed "placidity" or "tameness". Dietary changes and hyperphagia. Characterized by eating inappropriate objects (pica), or overeating, or both. Hyperorality. This was described by Ozawa et al. as "an oral tendency, or compulsion to examine objects by mouth". ...
The Metacognition and Motivation thrust has two broad goals, 1) to develop a better understanding of how metacognitive processes and motivation interact with learner factors to influence robust student learning outcomes and 2) to test whether and how student learning environments can leverage improved metacognition and motivation to increase the robustness of student learning. Our research will focus on a small number of metacognitive abilities (e.g., help seeking, self-explanation, interpreting peer feedback, and interpreting textual descriptions of domain principles), and a broader range of affective and motivational variables including: challenge perception, boredom, frustration, performance goals, and off-task behavior. The Metacognition and Motivation thrust builds on the Coordinative Learning (CL) cluster, while bringing a significant shift of focus. The M&M thrust continues some of the work in the Coordinative Learning cluster that focused on the metacognitive aspects of coordinating ...
