Résumé
Genetic prion diseases account for about 10-15% of all cases of human prion disease and are caused by mutations in the prion protein gene. Gerstmann-Sträussler-Scheinker (GSS) disease is a rare genetic prion disease, which is characterized by slowly progressive cerebellar ataxia and the occurrence of cognitive decline in the later stage. P102L is the most common mutation in GSS. We report a patient with a P102L mutation that initially manifested as rapidly progressive dementia without cerebellar symptoms.

Persistent aura without infarction is defined as an aura persisting for 1 week or more without evidence of infarction on neuroimaging. It is difficult to differentiate persistent visual aura without infarction from occipital lobe epilepsy. We report a Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy patient with prosopometamorphopsia and visual field defect improved by valproic acid. We also review ambiguity between visual aura in migraine and occipital lobe epilepsy.
