These attacks were usually not severe. Grand mal seizures are rarely seen in multiple sclerosis. In our own cases they have occurred in about 3 out of 1,000 patients. These seizures keep reoccurring, sometimes frequently, for three to six months, then disappear. On treatment of multiple sclerosis with the low-fat diet, these headaches usually become much less frequent and less severe, and they often disappear after one or two years.
Hypertension is rare, most patients having decidedly low blood pressure.
Both hypo- and hyperthyroidism are rare. Because of the patient's weakness, the clinical diagnosis of hypothyroidism is often made early but is not supported by laboratory evidence. Irregular or absent menses in females is a frequent complication of multiple sclerosis. The symptoms develop early or late and are usually accompanied by fatigue. In many cases, potency, sex drive, and normal menstruation return after recovering from the fatigue - usually after a long rest.
