Cerebral small vessel disease....does it lead to dementia? My mum (51) has recently had a TIA and has been diagnosed with CSVD. She has some dysphasia and memory trouble. She has had bloods.....all normal, lipids at 5.5 (put on meds to bring it down to 3.5), carotid dopplers - normal, all vitals are within normal limits, transthorasic echo and tranesophageal echo show normal heart function. She is however very worried about developing small vessel dementia. Does anyone know if SVD leads to dementia?
