UNALTERED 9 18% MASSACHUSETTS COMMISSION ON MENTAL DISEASES NOVEMBER, 1916 CHART 25 =Mentally=, there was a degree of depression and worry hardly out of keeping with the general situation. Despite the preservation of memory, Mr. Stone failed to do rather simple arithmetical calculations; this was the more remarkable as in his business he had to handle figures a great deal and had been doing so until recently. There was a slight tremor in his writing, as well as a certain difficulty in enunciating test phrases. Insomnia, irritability, and a feeling of nervousness and of being tired out, completed the picture. A suggestion for diagnosis would be classically offered by the Argyll-Robertson pupils. Should not a patient with the Argyll-Robertson pupils have either tabes or paresis? However, in favor of tabes, besides the pupil, are to be counted merely the troubles with the eyes. In the direction of paresis we have to consider speech defect, to say nothing of less definite symptoms such as insomnia and increased irritability. We are inclined to think, however, that the disease in this case is meningovascular. This diagnosis is suggested by the cranial nerve palsies and by the headache. Headache is much more rarely a phenomenon in the paretic type of neurosyphilis than in the meningovascular type. In point of fact, the spinal fluid phenomena bore out the diagnosis of MENINGOVASCULAR NEUROSYPHILIS inasmuch as the globulin, albumin, cellular content, gold sol, and W. R.’s were all weakly positive. 1. How far can we regard the cardiorenal defects as syphilitic? Perhaps we may do so on the general principle of parsimony in scientific interpretation. The diagnostic lumbar puncture led to an extremely severe exacerbation of the pains on the left side of the head. In fact, these pains could not be held in check by the exhibition of pyramidon. Mr. Stone regarded the pain as due to the lumbar puncture. However, there was no improvement in the pain in the prone position,—a feature characteristic of lumbar puncture pains. Upon administration of salvarsan, this local pain rapidly disappeared. In fact, there was a startling improvement; the ocular palsies disappeared in a few weeks, although these palsies had been present for several months before the administration of salvarsan. The blood pressure was reduced; the urine became negative. Perhaps the most startling feature of all (although of this we are not sure) was that the patient states he was accepted by a life insurance company although he had been twice refused previously.
