Abstract

A novel presenilin1 (PSEN1) mutation associated with dementia and spastic paraplegia in a family with five affected individuals is described. The index patient was a 35-year-old man presenting with cognitive decline, behavioural symptoms, dysarthria, and gait disorder due to spasticity.Genetic analysis revealed a missense mutation Gln223Arg in exon 7. Initial CSF analysis revealed drastically decreased Abeta42 level despite marginally decreased FDG metabolism.Cerebrospinal fluid biomarker analysis might point towards genetic analysis of PSEN1 in patients with positive family history and age of onset below 60 years.
