[Transient neurologic deficit preceding intracerebral hemorrhage. Physiopathological hypotheses]. / Déficits neurologiques transitoires précédant les hémorragies intraparenchymateuses. Hypothèses physiopathologiques.

Seventeen out of 238 cases (7%) of intracerebral hemorrhage were preceded by transient neurological deficit. In two cases, intracerebral hemorrhage and transient neurological deficit were thought to be due to amyloid angiopathy, this diagnosis was confirmed at autopsy in one case. In one case, intracerebral hemorrhage and transient neurological deficit were due to a cavernoma. In the other 14 cases, hypertension was the major risk factor. In 3 of them, CT-scans made after the transient neurological deficit but before the intracerebral hemorrhage showed deep small hypodensities suggestive of lacunas. The mechanisms of transient neurological deficit preceding intracerebral hemorrhage are reviewed.

[Investigation via electroencephalogram with sphenoidal electrodes of a case of reading epilepsy: role of the temporal lobe in the emotional evocation of seizures]. / Exploration d'un cas d'épilepsie à la lecture par EEG avec électrodes sphénoïdales: rôle des régions temporales dans le déclenchement émotionnel des crises.

Reading epilepsy in a 20-year-old male. Electroencephalographic study with sphenoidal electrodes localized the onset of critical spikes in the temporal areas (especially the left). The frequency and diffusion of critical spikes were increased when material read had an emotional content. This case report supports the "communication" hypothesis as opposed to hypotheses that emphasize proprioceptive and other "lower order" stimuli in evoking seizures while reading. The authors discuss the role of the temporal lobe in reading: lexical function, treatment of visual information and emotional integration of stimuli.

[Multiple cerebral embolism in acute alcoholic intoxication. A pathological case]. / Embolies cérébrales multiples au cours d'une intoxication alcoolique aiguë. Un cas anatomo-pathologique.

A 37 year-old man sustained 2 ischemic strokes during acute alcohol intoxication. One month after the onset of strokes, a spontaneous atrial flutter occurred. Autopsy revealed an embolic rostral occlusion of the basilar artery. Cardiac verification did not show myocardiopathy or coronary disease. The relations between acute alcoholic intoxication and paroxystic cardiac rhythm disorders are discussed.

[EEG periodic lateralized activities associated with ischemic cerebro-vascular strokes: physiopathologic significance and localizing value]. / Activités EEG périodiques latéralisées au cours des accidents vasculaires cérébraux ischémiques: signification physiopathologique et valeur localisatrice.

Eleven cases of periodic lateralized epileptiform discharges (PLED) with stroke (9 cases) or transient ischemic attacks are reported. PLEDs are often associated with depression of conscience (81%) or partial pure motor epileptic seizures (90%). PLEDs and seizures seem independent on EEG. Ischemic strokes associated with PLEDs have some characteristic features: old age, vascular risk factors, parieto-occipital areas infarcts and frequent association with TIAs. PLEDs seem to be often associated with watershed infarcts. The relations between PLEDs and cerebral ischemia are discussed.
