Neurologic symptoms are common during gestation and puerperium in CADASIL.

Based on a structured questionnaire and medical records, the authors found that 12 of 25 mothers with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) with the R133C NOTCH3 mutation had had neurologic symptoms in 17 of their 43 pregnancies, most commonly hemiparesthesia (76%), hemiparesis (36%), aphasia (65%), and visual disorders (47%). In 82% of the patients, the symptoms were the first manifestation of CADASIL. The symptoms were most common during puerperium and in patients older than age 30.
