Disease relevance of Agnosia

• On comparison with previously reported cases, our results support the hypothesis that carbon monoxide toxicity can induce a visual agnosia of the apperceptive type with well defined characteristics, seldom seen with other types of cerebral injury [1].
• This review will examine artistic production in individuals with a variety of syndromes including achromatopsia, neglect, visual agnosia, aphasia, epilepsy, migraine, dementia and autism [2].
• The MMPI, Portland Digit Recognition Test (PDRT; a forced choice measure of motivation), disability status, Face-Hand Test, and Finger Agnosia were compared in 53 patients with medically intractable seizure disorders who underwent intensive EEG monitoring [3].

Psychiatry related information on Agnosia

• RESULTS: Severe cognitive deterioration, such as acquired, apraxia and agnosia, was evident in 28.3% of those aged over 30 and a higher prevalence of these impairments was associated with older age [4].

High impact information on Agnosia

• One patient with a right inferior occipito-temporal lesion had a facial emotion imagery generation defect, other RHD patients displayed a facial affect agnosia (being impaired on emotional imagery and emotional perceptual tasks), while other RHD patients had perceptual defects with sparing of imagery performance [5].
• Associative visual agnosia was examined using the conceptual items of the Columbia Mental Maturity Test. Correlations between neurofibrillary tangle (NFT) and senile plaque (SP) densities and visual agnosia were studied using forward stepwise logistic regression [6].
• CPT: a cure for fiscal agnosia [7].
• The NES performance was significantly associated with functional neurological performance, including catching a ball, diadochokinesia, and finger agnosia [8].
• Literature update. Agnosia in Alzheimer disease [9].

Chemical compound and disease context of Agnosia

• Diazepam therapy of verbal auditory agnosia [10].
• The cerebral glucose metabolism of eight patients with schizophrenia and an olfactory agnosia was compared with that of eight normosmic patients with schizophrenia and eight normal controls [11].
• METHODS: The authors used standard cognitive tests and a novel battery designed to reflect dysfunction in both ventral (Object, Face & Color Agnosia Screen [OFCAS]) and dorsal (complex pictures and compound stimuli) visual streams [12].

Gene context of Agnosia

• RESULTS: A statistically significant relation was found between NFT densities in Brodmann's areas 18, 19, and 37, and associative visual agnosia, whereas NFT densities in the areas studied did not correlate with the presence of apperceptive visual agnosia [6].
• The language subtype of verbal auditory agnosia is associated with the highest risk of epilepsy in autistic (41%, 7 of 17) and dysphasic (58%, 7 of 12) children [13].
• A group of children (primarily learning disabled) was divided into analysis (n = 488) and cross-validation (n = 400) samples and the following measures were taken for both the LH and the RH Tactile Perception, Finger Agnosia, Fingertip Number Writing, Tactile Form Recognition, Finger Tapping, Grip Strength, Grooved Pegboard, and Mazes [14].
• The tactile impairment in monkeys with unilateral removals of area SII is seen as possibly analogous to the rare condition of tactile agnosia [15].
• The 'global' character of dementia distinguishes it from other organic syndromes but in community surveys memory impairment is the predominant early symptom and the aphasia, apraxia and agnosia triad characteristic of dementia of Alzheimer type disease (DAT) may be hard to demonstrate [16].
