amnesia/脳卒中

BACKGROUND Embolic stroke is a complication of Tako-Tsubo-cardiomyopathy (TTC), transient left ventricular dysfunction mimicking myocardial infarction without coronary culprit lesion explaining the whole left ventricular dysfunction. Transient global amnesia (TGA) is characterized by sudden onset of

Four patients who experienced isolated transient global amnesia had computed tomographic evidence for a cerebral infarct (3 cases) or hemorrhage (1 case). The medial part of the temporal lobe was involved in 2 patients (left in 1, right in 1), the left lentiform nucleus in 1 patient, and the left

A 61-year-old man suffered an episode of transient confusion and anterograde amnesia after a Valsalva-related manoeuvre. The MRI diffusion weighted imaging (DWI) sequences showed a left hippocampal and two right parietal lesions that were deemed as acute. The MR angiography disclosed a high-grade

A 60 year old right-handed man developed severe amnesia following a left medial temporal stroke as documented by cerebral MRI, MRA and SPECT scans. Neuropsychological evaluation 13 weeks after the stroke showed a profound retrograde amnesia characterised by memory loss for public facts and events

We report a case of migraine-associated ischemic stroke causing amnesia, wherein treatment with propranolol may have been contributory. The possible mechanisms involved in migrainous stroke occurring in association with use of propranolol are discussed.

The acute onset of isolated amnesia is an intriguing challenge for neurologist, because the lack of associated signs can be misleading for diagnosis. The most common cause is transient global amnesia (TGA), a benign condition, but rarely it results from abuse of substance/alcohol or cerebrovascular

OBJECTIVE Whether transient global amnesia (TGA) represents an arterial insult that heralds ischemic stroke remains unclear. Therefore, we examined stroke risk after TGA in a population-based cohort. METHODS After performing chart review at our institution to validate the International

Background and Purpose- Transient global amnesia (TGA) is known as a benign syndrome, but recent data from neuroradiological studies support an ischemic cause in some cases, which might suggest an increased susceptibility to cerebrovascular events. We determined the long-term risk of stroke after a

The 11-year longitudinal study of a right-handed male patient, L. C., who suffered from a severe amnesic syndrome following a softening in the right thalamus, is reported. Memory impairment involving retrograde and long-term anterograde memory, both verbal and spatial, persisted without

We discuss a patient who presented to our hospital with signs, symptoms, and clinical course consistent with transient global amnesia (TGA). Her hospital work-up was overall unremarkable except for the presence of a diffusion weighted imaging (DWI) abnormality on MRI suggestive of acute infarction

The clinical manifestations of thalamic hemorrhage frequently comprise hemiparesis, hemianesthesia, and oculomotor abnormalities. Since the advent of computed tomography, an amnestic syndrome following thalamic hemorrhage has been recognized, but the thalamic structures involved and the mechanism of

Ischemia has been proposed as a cause of transient global amnesia (TGA), but proof has been lacking. The authors performed magnetic resonance imaging on a 77-year-old woman with classic TGA at 4 hours and at 6 days after the onset of symptoms. Her initial diffusion-weighted imaging (DWI) and

The "learned non-use phenomenon" described by Taub, one of the most original recent contributions to rehabilitation medicine probably corresponds to what Henry Meige (1866-1940), who studied under J.-M. Charcot, described in hemiplegics in 1904 using the expression "functional motor amnesia". He
