Abstract

We evaluated 38 consecutive patients with corticobasal syndrome to determine if inheritance of the H1/H1 genotype influences age at onset and disease severity and if Apolipoprotein E e4 increases the risk of cognitive disturbances. Inheritance of the H1/H1 genotype was associated with severity of motor function, but did not affect age at onset or cognition. There was a trend toward shorter survival in the H1/H1 group, but this study was underpowered to test influence on survival, even though it served to estimate the sample size for future studies. ApoE inheritance did not influence cognition. © 2009 Movement Disorder Society
