| Opplysninger | Objectives. To investigate whether the presence of hippocampalatrophy (HCA) on MRI in Alzheimer's disease (AD) leads to a more rapid decline in cognitive function. To investigate whether cognitively unimpaired controls and depressed subjects with HCA are at higher risk than those without HCA of developing dementia.Design. A prospective follow-up of subjects from a previously reported MRI study.Setting. Melbourne, Australia.Participants. Five controls with PICA and five age-matched controls without HCA, seven depressed subjects with HCA and seven without HCA,and 12 subjects with clinically diagnosed probable AD with PICA and 12 without HCA were studied. They were followed up at approximately 2 years with repeat cognitive testing, blind to initial diagnosis and MRI result.Measures. PICA was rated by two radiologists blind to cognitive testscore results. Cognitive assessment was by the Cambridge Cognitive Examination (CAMCOG).Results. No significant differences in rate of cognitive decline,mortality or progression to dementia were found between subjects with or without PICA.Conclusions. PICA was not found to be a predictor of subsequent cognitive decline in this series.
