Hydrocephalic patients often show a great passion for venereal indulgences. Gall, in noticing this remark, observes, that of all the parts of the encephalon, this is the least changed in these individuals. Chauffard has seen a hydrocephalic patient, fourteen to fifteen years old, with an enormous head, who was addicted to masturbation, and spoke of the pleasures he derived from it.
An acute or chronic irritation of the cerebellum, or of its envelopes, may cause venereal symptoms more than the alterations just mentioned. In a cadaver, brought from the hospital Bicetre to the amphitheatre, where the penis and testes were considerably swelled, the whole of the cerebellum was inflamed. One of the most interesting facts of this kind was reported by Chauffard. It was that of a man, fifty-three years old, of pleasant manners and mild character, who, in falling, struck his head against the bed-post. The inferior occipital region became inflamed; and subsequently, the habits of the patient were much changed: he became affected with satyriasis, and was so salacious, that he persecuted his wife and daughter, and all the females around him. This man, hitherto pious and modest, gradually became affected with the most violent erotic delirium, and finally committed the most indecent acts. During the next three months, this state increased; but, at the same time, his strength and intelligence failed. Finally, one day, after a violent fit of anger, occasioned by the refusal of his wife to listen to him, he became convulsed. The pain left the back part of the head, and affected the top of it. The left side of the body now began to be paralyzed; and the satyriasis was replaced by religious delirium, with constant mumbling of prayers. The patient died eight days afterward. According to Chauffard, at first, there was an affection of the cerebellum. When the state of the patient was changed, the organ of veneration was affected: this organ corresponds to the central posterior and superior part of the frontal bone, where the patient finally felt severe pain.
Was not the cerebellum, also, affected, in the following case reported by Sainte Marie:--“A merchant of Lyons, an educated and honorable man, seemed to be cured of an inveterate venereal affection, for which he had undergone a course of treatment with mercury. He, however, complained of restlessness, heat in the throat, _pains in the occiput and nucha_, and frequent erections. In 1812, after domestic troubles, he became affected with furious delirium. This state lasted three days, and terminated in priapism; during which, the patient had fourteen emissions in a few hours. This singular crisis resulted in a perfect calm: extreme debility, however, remained, which soon yielded to tonics and analeptics. Two years and a half afterward, this disease reappeared, under the influence of these same causes, and with similar symptoms. The termination was the same. There was a slight return of it after two years; but, this time, the patient escaped with slight erections, without much loss of semen.”
