The authors present a 91-year-old woman with the clinical picture of slowly progressive dementia, initially with slight paresis on the right side. Magnetic resonance imaging (MRI) revealed symmetrical periventricular white matter abnormalities and extreme dilatation of perivascular spaces, predominantly in the left hemisphere. They were accompanied with periodic lateralized epileptiform discharges (PLEDs). Dementia is possibly caused in this case through functional impairment of the left hemisphere.
