title: [A patient with early Alzheimer's disease who showed improvement of cognitive function and cerebral perfusion by combined therapy of nilvadipine and PPAR gamma agonists].
abstract: A 76-year-old man was referred to our hospital because of memory impairment. He was diagnosed as having early Alzheimer's disease, in addition to hypertension and type II diabetes mellitus. Nilvadipine (a Ca-channel blocker), telmisartan (an angiotension II receptor blocker), and pioglitazone (an insulin sensitizer) were administered for the control of the hypertension and diabetes. After 6 months of treatment, the scores on verbal fluency (animals and vegetables/60 seconds) and frontal assessment battery of the patient improved despite no significant changes on the Mini-Mental State Examination and Alzheimer's Disease Assessment Scale. Moreover, follow-up examination of SPECT demonstrated an improvement of cerebral perfusion in the frontal and temporoparietal regions. In addition to nilvadipine, a highly lipophilic Ca channel antagonist agent that easily penetrates the central nervous system, PPARgamma agonists, such as pioglitazone and termisartan, may have had favourable effects on cognitive function and cerebral perfusion in this patient.
