sometimes accompany growths in the posterior lobes. Kraepelin has also observed hallucinations in cases with tumor of the cerebellum. Many develop hypochondriacal ideas, others have delusions of persecution or self-accusation and suicidal tendencies. Rarely there are delusions of grandeur. The mood is usually anxious, depressed and at times irritable or apathetic. Occasionally the patients may, on the other hand, be cheerful in spite of the hopeless condition they are in. They may even show distractibility, flight of ideas, volubility and excitement. There is more often a childish elation with a tendency to joking and facetiousness. Schuster found this more common in frontal involvements. Kraepelin also called attention to restlessness and excitements often leading to violence. This may alternate with mental dulness and cataleptic states. The patients may repeat words and make meaningless response to questions, strongly suggesting katatonia. Mental dulness becomes more and more marked, however, even reaching a stuporous stage. To this is added, according to the location of the growth, focal symptoms of various kinds—headache, disturbance of vision, seizures, paralyses, aphasia, agraphia, articulatory disturbance, ataxia, etc. Special symptoms arise where psychogenic factors play a part,—excitements with paralyses or disturbance of perception, etc. Hysterical stigmata may appear. Cases with growths in the frontal region occasionally simulate general paresis but should be distinguished without difficulty. The Association's statistical manual has the following to say of psychoses with brain tumor:— "A large majority of brain tumor cases show definite mental symptoms. Most frequent are mental dullness, somnolence, hebetude, slowness in thinking, memory failure, irritability and depression, although a tendency to facetiousness is sometimes observed. Episodes of confusion with hallucinations are common; some cases express suspicions and paranoid ideas. "The diagnosis must rest in most cases on the neurological symptoms, and these will depend on the location, size and rate of growth of the tumor. Certain general physical symptoms due to an increased intracranial pressure are present in most cases, viz.: headache, dizziness, vomiting, slowing of the pulse, choked disc and interlacing of the color fields." The number of cases reaching hospitals for mental diseases is, of course, small. In 49,640 first admissions to the New York state hospitals in eight years there were sixty-seven cases (.14 per cent) of psychoses with brain tumor. In 18,336 admissions to twenty-one hospitals in fourteen other states there were eighteen cases (.09 per cent) diagnosed as psychoses with brain tumor. There were ninety-three cases (.13 per cent) in 70,987 first admissions to forty-eight hospitals for mental diseases in sixteen different states. _Psychoses with Other Brain or Nervous Diseases_
