Violence done under the influence of clearly-defined hallucinations and delusions is most dangerous, because it is executed with apparent deliberation and volition. Thus, a man laboring under hallucinations of hearing, fancying himself insulted, may turn in the street and strike or shoot some one near him, the supposed author of the insult. An epileptic falls in a partial attack or has epileptic vertigo; as a part of the seizure there is a dream-like scene of assault, actual or threatened, upon him, and on rising from the ground, or after the momentary vertigo the patient, acting in accordance with the demands of the dream-like scene, makes an onslaught upon those near him or smashes furniture, etc. Seeing such acts, without knowing their genesis, one is liable to consider them normally deliberate and malicious. On recovering consciousness (which may not be for several hours or days) the epileptic patient appears utterly oblivious of his actions, and is much astonished to learn what he has done. In many cases of insanity violent acts are done through a similar psychic mechanism—_i.e._ through the domination of delusions. Delusions often give rise to what may be termed negative violence—resistance to personal care, treatment, giving of food, etc. This is exemplified in acute melancholia, with overpowering fears of all kinds and terrorizing hallucinations of sight and hearing. The patients crowd in corners or sit curled up, and resist with all their might whatever is done for them, even striking and biting the attendants. Therapeutically, the question of physical restraint or non-restraint in the management of violence might be discussed here, but the question is one which can be much better considered in connection with the general treatment of insanity, and the reader is consequently referred for information to the article on that subject.
