Recent anatomoclinical and neuroimaging studies have suggested a possible relation between @entity3119 ( @entity3119 ) and some @entity75 , such as @entity75 , basal ganglia cavitations and local @entity413 @entity209 . A poor frontocaudal regulation of the left hemisphere and an @entity16 in @entity3119 @entity1 have been supposed. To absess these morphofunctional abnormalities, an electrophysiological approach has been performed in 100 consecutive @entity6004 @entity1 , screened with various neuropsychological tests and divided in two groups, 50 with @entity3119 and 50 with @entity11167 ( @entity11167 ). @entity1 were submitted to EEG spectral analysis and BAEP studies and comparated with 25 age-matched normal controls. The mean alpha power in occipital regions was significantly higher in @entity3119 @entity1 and reduced in @entity11167 @entity1 . A significant reduction of the beta activity was recorded in frontal regions in both @entity1 groups as compared to controls. A slight (p < 0.11) increase in I-V interpeak latency (IPL) vs. control group was observed in BAEP from left ear. A significant increase of the same IPL in @entity3119 vs. controls (p < 0.025) was observed in BAEP from right ear. A slight n.s. reduction in III wave amplitude in @entity3119 @entity1 was observed in BAEP from left ear, whereas a highly significant reduction in the same wave amplitude from BAEP from right ear was observed in @entity3119 @entity1 . The above findings cold be account for both a @entity409 with a probable involvement of serotoninergic central pathways, with a significant impairment of pontine segment in @entity11167 @entity1 and of mesencephalic region in @entity3119 @entity1 .
