A Study of Cerebral Atrophy on the Brain CT in Chronic Alcoholics and Patients with Dementia of Alzheimer Type

To study the cerebral atrophy in chronic alcoho- lies and patients with dementia of Alzheimer type， authors measured the Evans’ ratio, frontal horn：ratio, bicaudate ratio, cella media ratio, 3rd ventricle- Sylvian fissure/skull ratio, and sum of 4 sulci in brain CT films of 13 chronic alcoholics^ J.5 patients with dementia of Alzheimer type, and 18 control group of “radiologically normal”. The results were as follows： 1. Chronic alcoholics and patients with dementia of Alzheimer type were found significant cerebral atrophy than control group in the all ratios. 2. The difference of the degree of cerebral atrophy score between chronic alcoholics and patients with dementia of Alzheimer type was not statistically significant, and similar score was: found on the both groups. 3. The sulcal widening was most sensitive among the variable cerebral atrophy measurements
