[Ischemic strokes in young adults and illegal drugs].

One out of four ischemic strokes in France occurs in adults under 65 years old. About a third of them remain unexplained even after an extensive etiological assessment. A large part of these unexplained strokes could be linked to illegal drug abuse, and 10 % are estimated to be directly linked to illegal drugs in some international studies.

[Transient Epileptic Amnesia: a case report and a reappraisal].

Transient Epileptic Amnesia is a late-onset form of temporal lobe epilepsy characterized by recurrent attacks of transient retrograde and anterograde amnesia usually lasting less than one hour and beginning in late-middle to old age. Attacks commonly occur on waking, a potentially helpful diagnostic clue. The amnesic attacks may be associated with persistent memory complaints.

De novo epileptic confusion in the elderly: a 1-year prospective study.

Purpose: Nonconvulsive status epilepticus (NCSE) is clinically difficult to diagnose, especially in old patients without epilepsy, and requires electroencephalography (EEG) for diagnosis. Its incidence among elderly patients with confusion of unknown origin (CUO) remains undetermined.

Methods: A 1-year prospective study was conducted in patients aged 60 years or older, for whom EEG was requested because of confusion considered to be of unknown origin after initial clinical, biologic, and imaging investigations.

[Idiopathic transient global amnesia].

Transient global amnesia (TGA) is characterized by a severe disturbance of memory, occurring rapidly, lasting less than a day and mainly affecting elderly subjects. During its acute phase, it is characterized by a severe anterograde amnesia, partial retrograde amnesia and anxiety with repetition of the same questions. The diagnosis is purely based on patient's clinical features.
