From Serafimerlazarettet comes this complex study, in which hemispheral dominance is elaborated in greater detail than previously. The conclusion is reached, on the basis of skilled acts and aphasia, that the left hemisphere is dominant in 99% of right-handed patients but that the right hemisphere is dominant in only 50% of left-handed persons. Ninety patients with temporal lobe epilepsy were thoroughly studied and compared with 253 patients with temporal lobe gliomas. By statistical methods the author concludes that certain mental symptoms are independent both of intracranial hypertension and of aphasia, and are not due to reactions to the disorder. A special group of 16 patients harbored benign gliomas, with seizures as the only manifestation. Emotional blunting and flattening of affect were found in eight of nine patients with glioma of the dominant temporal lobe, while only one of seven patients with tumor of the recessive lobe showed similar features.
