Progressive transcortical sensory aphasia and progressive ideational apraxia owing to temporoparietal cortical atrophy
BACKGROUND In contrast to frontotemporal lobar degeneration, atrophy of the focal posterior lateral cortex has not been thoroughly studied. Three clinical types of focal cortical atrophy have been described: 1) logopenic variant of primary progressive aphasia, which presents with impaired repetition despite normal articulation; 2) posterior cortical atrophy, which presents with prominent visuos...
متن کاملPatterns of limb apraxia in primary progressive aphasia.
Primary progressive aphasia (PPA) is a syndrome characterized by a progressive language deficit without other dementia features for at least two years (). Other deficits that are likely to co-exist with aphasia, such as apraxia, have only been investigated in a few case studies and only at a rudimentary level for the most part. In this study we investigate the frequency and severity of apraxic ...
متن کاملTranscortical sensory aphasia: revisited and revised.
Transcortical sensory aphasia (TSA) is characterized by impaired auditory comprehension with intact repetition and fluent speech. We induced TSA transiently by electrical interference during routine cortical function mapping in six adult seizure patients. For each patient, TSA was associated with multiple posterior cortical sites, including the posterior superior and middle temporal gyri, in cl...
متن کاملprogressive hemifacial atrophy
progressive hemifacial atrophy, also known as parry-romberg syndrome, is an uncommon degenerative and poorly understood condition. it is characterized by a slow and progressive but self-limited atrophy affecting one side of the face. the incidence and the cause of this alteration are unknown. a cerebral disturbance of fat metabolism has been proposed as a primary cause. possible factors that ar...
متن کاملMechanism of repetition in transcortical sensory aphasia.
A typical case of transcortical sensory aphasia (TSA) is presented, in which the Wada test suggests that it is the right hemisphere which enables the patient to repeat orally. It is supposed that one of the mechanisms of preserved repetition in TSA is linked to an exceptional ability for repetition of the right hemisphere, which may help to explain why cases of TSA are so rare.
