The phenomenon of retrograde amnesia has important implications for understanding normal memory as well as its neural organization. Using 6 tests of remote memory, we evaluated the extent and severity of retrograde amnesia in 2 groups of amnesic patients-7 patients with alcoholic Korsakoff’s syndrome and 5 other patients with amnesia (anoxia or ischemia, N = 3; thalamic infarction, N = 1; unkno...

Specialized techniques may make it possible to induce selective 'amnesia' in machine learning models.

A middle-aged woman began experiencing spells of profound anterograde amnesia several months after beginning intrathecal baclofen treatment for generalized dystonia. Her spells met criteria for transient global amnesia, but were unusual because of their frequent recurrence and because their frequency was somewhat dose-dependent on baclofen. Fludrocortisone decreased the frequency of these episo...

OBJECTIVE To present the case of a collegiate pitcher with type I diabetes mellitus who developed transient global amnesia and to characterize the acute onset of symptoms and clinical diagnosis of this rarely reported neurologic condition in the student-athlete population. BACKGROUND A 21-year-old collegiate pitcher with type I diabetes mellitus was found by his roommate to have acute-onset m...

BACKGROUND Some studies have shown the presence of psychopathological disorders in transient global amnesia. AIMS To determine whether transient global amnesia is associated with psychopathological disorders and to assess the influence of these psychopathological disorders on memory impairments. METHOD Levels of anxiety and depression before and during transient global amnesia were rated. M...

We have studied the effect of i.v. flumazenil 0.01 mg kg-1 on the amnesia and sedation caused by midazolam 2 mg and 5 mg i.v. in volunteers in order to determine the relationship between the actions of the antagonist on these two effects. Midazolam caused dose-dependent central neural depression as assessed by critical flicker fusion frequency, and dose-dependent amnesia for word cards. In subj...

Attribute amnesia is the counterintuitive phenomenon where observers are unable to report a salient aspect of a stimulus (e.g., its colour or its identity) immediately after the stimulus was presented, despite both attending to and processing the stimulus. Almost all previous attribute amnesia studies used highly familiar stimuli. Our study investigated whether attribute amnesia would also occu...
