Just as hippocampal lesions are principally responsible for “temporal lobe” amnesia, affecting the anterior thalamic nuclei seem a similar loss of memory, “diencephalic” amnesia. Compared with former, causes diencephalic amnesia have remained elusive. A potential clue comes from how two sites interconnected, within formation, only subiculum has direct, reciprocal connections nuclei. We found th...

Patients with transient global amnesia are often categorized as having cerebrovascular disease. Noninvasive carotid artery testing was performed in 56 patients with transient global amnesia to determine if they had the same incidence of extracranial atherosclerotic vascular disease as patients with focal cerebral transient ischemic attacks. Only 3 of 56 patients had hemodynamic obstruction of f...

The charts and radiographs of 12 of 1,520 patients who developed amnesia after transfemoral cerebral angiography performed with local anesthesia and minimal sedation were retrospectively reviewed. In three younger patients, exacerbation of organic or idiopathic temporal lobe epilepsy was thought to be the cause of the amnesia, while the amnesia of the nine patients over 40 years old had the cha...

Memory may be crucial for establishing and/or maintaining social bonds. Using the National Social life, Health, and Aging Project questionnaire, we examined close interpersonal relationships in three amnesic people: K.C. and D.A. (who are adult-onset cases) and H.C. (who has developmental amnesia). All three patients were less involved than demographically matched controls with neighbors and re...

R ev ie w Neurotransmitter modification is an important method for the treatment of memory loss or amnesia. Cholinomimetic drugs, particularly, acetylcholine esterase inhibitors are the mainstream in pharmacotherapy of amnesia. Donepezil, tacrine, galantamine, and rivastigmine are cholinesterase inhibitors which are widely used in the treatment of amnesia, however, their therapeutic effects are...

Stroke is an extremely uncommon cause of transient global amnesia (TGA). Unilateral lesions of the fornix rarely cause amnesia and have not previously been reported to be associated with the distinctive amnesic picture of TGA. We describe the case of a 60-year-old woman who presented with acute onset, recent retrograde, and anterograde amnesia characteristic of TGA. Serial magnetic resonance im...

After a head injury, a 58-year-old patient presented a severe deficit in face recognition. Bilateral temporo-occipital hematomas were drained. Associated with this deficit in face recognition, the patient presented visual hypoemotionality (hyporeactivity to visual stimuli) and transient gustatory amnesia. Some topographic amnesia and mild anomia were also present. Five years later, difficulties...
