Out of 110 autopsies done at the Nornstown State Hospital only three givealcohol as a contributing factor directly. Sixteen cases diagnosed as Paresis give a distinct history of primary infection,while twenty-four psychoses with gross Brain Lesion show arteriosclerosis of cerebralvessels to be By far the largest number, 54 in all, were found in the senile form of psychosisand brings out the factor mentioned previously in this article, viz.: that it is a questiondepending upon the degree of narrowing in the lumen of these vessels, since senilechange is in a way a physiological function. The majority of these patients hadstrenuous occupations before admittance to the hospital. Epilepsy shows cerebral arterio-sclerosis and is probably a result of the continuedcongestion produced by the convulsive seizures. In two cases of Infective Exhaustivepsychosis arterio-sclerosis was present. Of course, Dementia Praecox of long standing is bound to show some thickeningbut not to such a marked degree as those which have a distinct contributing factor.
