PET showed diffused hypometabolism of the cortical and subcortical regions of the two cerebral lobes, sparing partially the occipital cortex, the basal ganglia and the cerebellar cortex (Figure 1). Patient evolution was marked by a fluctuating hyperactive delirium treated by quetiapine, clonidine and melatonin.
