We investigated whether a self-rated anosognosia score can be an indicator for progression of brain atrophy in patients with amyotrophic lateral sclerosis (ALS). Scores for 16 patients were compared with the ventricular areas of the bilateral anterior and inferior horns measured on x-ray computed
A patient of posterior cortical atrophy characterized by early signs of progressive visual agnosia documented by repeated neuropsychological tests, is reported. SPECT and MRI findings showed left unilateral parieto-occipital involvement in the earlier stage. A PET study executed eight months later
Interest in progressive focal cerebral syndromes associated with classical degenerative diseases has increased in recent years. Descriptions of posterior cortical atrophy with progressive visual agnosia are relatively rare. We present 5 patients (2 women) ranging in age between 57 and 72 years old.
BACKGROUND
Posterior cortical atrophy (PCA) is a degenerative disease characterized by progressive visual agnosia with posterior cerebral atrophy. We examine the role of the picture naming test and make a number of suggestions with regard to diagnosing PCA as atypical dementia.
METHODS
We
A 60-year-old, right-handed woman, with no focal brain lesions, suffered from a progressive impairment in recognising people of personal relevance and public figures familiar to her in the premorbid period. The patient did not suffer from general cognitive deterioration. There was no ecological or
OBJECTIVE
Posterior cortical atrophy (PCA) is characterized by progressive visuoperceptual and visuospatial deficits and commonly considered to be an atypical variant of Alzheimer disease. Mutations of the GRN gene are responsible for a large phenotypic spectrum, but, to our knowledge, the
The case of a 64-year-old woman affected by slowly progressive visual agnosia is reported aiming to describe specific cognitive-brain relationships. Longitudinal clinical and neuropsychological assessment, combined with magnetic resonance imaging (MRI), spectroscopy, and positron emission tomography
Surgery for an area of focal cortical dysplasia in a critical region is reported in a right-handed female manifesting intractable focal epilepsy and verbal cognitive deterioration. She developed the first seizure at 2 years of age and was treated with phenytoin and zonisamide, with good control
Patients with posterior cortical atrophy may have dorsal visual system (occipital-parietal) dysfunction (optic ataxia, visuospatial disorientation, and simultanagnosia), ventral visual system (occipital-temporal) dysfunction (pure alexia, prosopagnosia, visual anomia, and agnosia), or both. We
Anosognosia is a term now generally defined as a failure to recognize the existence of disease processes, particularly those with a neurological basis. Denial of illness has been recognized in a large number of disorders, and is generally thought to have not only a central nervous system basis, but
Thirty-nine male patients (median age 61, range 19-92) from a neurologic ward were examined by a test for prosopo-affective agnosia (PAA), i.e., impairment in the recognition of facial affect (emotions) with no impairment in the recognition of facial features (PA, prosopo-agnosia). The scores for
We report a patient with a unique visual agnosia, who was thought to have lost visual functions except for the primary visual function. The patient was a 71-year-old woman with progressive memory loss and cerebro-cortical atrophy in MRI; her clinical diagnosis was senile dementia of Alzheimer's
