The association between epilepsy and amnesia is studied in patient J.T. who presented with a very unusual pattern of memory loss with retention of information for hours to days but rapid forgetting of information that exceeded this time frame. J.T.'s unusual memory profile was studied with several tests administered over week-long intervals of time. There(More)
BACKGROUND Prosopagnosia, the inability to recognize faces, is associated with medial occipitotemporal lesions, especially on the right. Functional imaging has revealed a focal region in the right fusiform gyrus activated specifically during face perception. OBJECTIVE The study attempted to determine whether lesions of this region were associated with(More)
OBJECTIVE To define the behavioral profile of periventricular nodular heterotopia (PNH), a malformation of cortical development that is associated with seizures but reportedly normal intelligence, and to correlate the results with anatomic and clinical features of this disorder. METHODS Ten consecutive subjects with PNH, all with epilepsy and at least two(More)
BACKGROUND Some patients with prosopagnosia have covert recognition, meaning that they retain some familiarity or knowledge of facial identity of which they are not aware. OBJECTIVE To test the hypothesis that prosopagnosic patients with right occipitotemporal lesions and impaired face perception lack covert processing, whereas patients with associative(More)
OBJECTIVE Two procedures for treating major depressive disorder were compared with regard to their respective effects on mood and cognition. BACKGROUND Fourteen patients underwent treatment with electroconvulsive therapy and 14 underwent treatment with repetitive transcranial magnetic stimulation. Patients were tested on three occasions: before initiation(More)
It has been hypothesized that social developmental disorders (SDD) like autism, Asperger's disorder and the social-emotional processing disorder may be associated with prosopagnosic-like deficits in face recognition. We studied the ability to recognize famous faces in 24 adults with a variety of SDD diagnoses. We also measured their ability to discriminate(More)
Two studies explored the stability of art preference in patients with Alzheimer's disease and age-matched control participants. Preferences for three different styles of paintings, displayed on art postcards, were examined over two sessions. Preference for specific paintings differed among individuals but AD and non-AD groups maintained about the same(More)
Three Words - Three Shapes was designed as an easy "bedside" test for elderly patients that assesses verbal and nonverbal memory within the same modality. In the present study, it was administered to patients with probable Alzheimer's disease (PRAD), a control group of non-demented older subjects (NC) and a group of patients with Korsakoff's amnesia (KA).(More)
This paper explores potential cognitive deficits underlying confabulation of patient, G.S., following an anterior communication artery aneurysm. G.S.'s performance on tasks assessing memory for temporal duration, temporal order, and speaker identification is examined as is his recollection of autobiographical events. We compare G.S. with three(More)
A patient with amnesia due to encephalitis was previously described in 1976 as having normal short-term memory and an intact ability to perform semantic analysis. Despite this ability, his retention beyond the limits of short-term memory was nearly nil. The present investigation sought to evaluate more completely the nature of this patient's retrieval(More)
