For the last four years she has had seizures which may be attributed to her idea that she must see the whole of the objects on her left. Under the impulse of this idea, she turns her eyes upwards and to the left, rotates her head in the same direction, and her body too, if she happens to be on her feet. The performance is gone through fifteen or twenty times a day. In addition, she suffers from epileptiform attacks, which commence by this deviation of head and eyes to the left, and spread to the arms and to the left leg, leading to loss of consciousness as they become generalised. The patient finally succumbed to an apoplectic stroke followed by left hemiplegia. In this instance the connection between the fixed idea and the patient's gesture favours the diagnosis of tic, but the subsequent history of the case makes one consider it with reserve. All such cases ought to be followed up carefully, and we may modify Féré's conclusions somewhat to declare that the appearance of a convulsive movement in an adult, or the aggravation of a similar movement of ancient date, should lead one to suspect epilepsy and to look for signs of it: "The patient runs more chance than risk in being treated as an epileptic." We have had the opportunity of observing, in one of our mental torticollis cases, a condition not unlike what is known as _absence épileptique_. The term "incantation" was applied by the parent to his daughter's habit. On two occasions we noticed the patient's eyes turn upward and remain fixed for a moment or two, while her expression changed to one of tranquillity and unconcern--a sign of distraction, not of ecstasy. She merely appeared to be thinking of something other than the immediate topic of conversation, and after two or three seconds resumed her ordinary ways. These brief "absences" are trifling enough, of course, but their painstaking study is of inestimable aid in the matter of diagnosis. They began at the age of seven or eight, and at first occurred as often as sixty times in a day. What the patient did was to raise her head, and turn up the whites of her eyes; in a second or two her countenance had resumed its ordinary expression. From their onset, the "incantations"--to use her father's term--gradually increased in frequency and length, and attained a sort of maximum when she was eleven years old, slowly diminishing thereafter till at present they have become rather exceptional. They proved to be a source of great tribulation to L., seeing that she was exposed to the practical jokes of her companions, who used to seize the occasion to relieve her of any books or toys she had in her hand.
