The cerebellum has been associated with several motor functions including maintenance of posture, coordination and balance. Its role in attention and classical conditioning has also been well described158. Neuroimaging studies have consistently reported reductions of cerebellar volume and surface area in subjects with PEA140, 141. Within the cerebellum, several studies have observed regional specificity of alcohol effects141, 159. Abnormalities in balance, coordination and attention observed commonly in subjects with PEA can be neuroanatomically correlated to the cerebellar abnormalities.
