Description : Gerstmann-Straussler disease is a rare inherited prion disease characterized by adult
onset of memory loss, dementia, ataxia, and pathologic deposition of amyloid-like
plaques in the brain (Gerstmann et al., 1936). Gerstmann-Straussler disease typically
presents with progressive limb and truncal ataxia, dysarthria, and cognitive decline
in the thirties and forties, and the average disease duration is 7 years. GSD can
be distinguished from CJD by earlier age at onset, longer disease duration, and prominent
cerebellar ataxia (Masters et al., 1981). On the basis of clinical and pathologic
criteria, Hsiao et al. (1989) suggested that Gerstmann-Straussler syndrome could be
classified into 3 forms: an 'ataxic' form, a 'dementing' form, and a dementing form
that is accompanied by pathologic quantities of neurofibrillary tangles (NFTs). However,
these distinctions may only underscore the phenotypic variability in presentation
and progression of the disease (Panegyres et al., 2001).;
