Grey matter voxel-based morphometry.

<div><p>Areas of reduced grey matter density (depicted on the MNI152 brain) compared to age- and sex-matched controls using voxel based morphometry (highlighted areas, corrected, p<0.05). </p> <p>A) Patients with GA show pancerebellar grey matter reduction. B) Patients with ACAA show cerebellar hemispheric grey matter reduction as well as cingulate gyrus and inferior frontal lobe involvement. C) Patients with ataxia due to chronic alcohol abuse that also demonstrate sensitivity to gluten. Note this is the same pattern of disease as shown in patients with ACAA (B) and differs to that of GA(A). </p>
