Cognitive impairment and cerebral hypoperfusion in a CADASIL patient improved during administration of lomerizine.
A 64-year-old woman was admitted to our hospital for recurrent stroke and cognitive impairment and was diagnosed with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Iodine-123 iodoamphetamine single photon emission computed tomography showed hypoperfusion in the whole brain, but cerebral blood flow increased dramatically after the administration of acetazolamide in the cerebral cortex. Lomerizine, a diphenylmethylpiperazine Ca2+ channel blocker, can selectively increase cerebral blood flow. Cognitive decline and cerebral hypoperfusion improved during 2-year administration of lomerizine in this CADASIL patient, and thus, lomerizine is a potential candidate for treating cognitive impairment in CADASIL patients.
