Migraine headaches that occur in the 15- to 30-year-old age group are well documented. In patients in the stroke age bracket, however, who present with a history of neurologic deficit, transient ischemic attacks can be confused with migraine accompaniments. The typical patient is 50 years old, is without a past history of migraines, and complains of scintillating visual disturbances (20 percent), marching paresthesis (22 percent), or a myriad of neurologic deficits. In one series of 70 neurology patients aged over 55 years, 16 percent reported that they experience the new onset of scintillations. Once fully evaluated, the cause of unexplained marching paresthesias, dysphagia, or hemiplegia, once reserved for thrombotic or embolic phenomena, may be attributed to migraine accompaniments. In the face of a normal evaluation, neurologic deficit in the stroke age bracket may be attributed to migraine accompaniments. A case of a 47-year-old woman with sudden onset of left-sided paresthesia, dysarthria, and confusion is presented. The discussion includes a description of migraine pathophysiology and a review of concepts regarding accompaniments.

The benzodiazepines are still extensively used in psychiatry, neurology and medicine in general. Anxiety disorder and severe insomnia are important syndromal indications, but these drugs are widely prescribed at the symptomatic level, resulting in potential overuse. The official data sheets recommend short durations of usage and conservative dosage. Although short-term efficacy is established, long-term efficacy remains controversial, as relevant data are scanty and relapse, rebound and dependence on withdrawal not clearly distinguished. The risks of the benzodiazepines are well-documented and comprise psychological and physical effects. Among the former are subjective sedation, paradoxical release of anxiety and/or hostility, psychomotor impairment, memory disruption, and risks of accidents. Physical effects include vertigo, dysarthria, ataxia with falls, especially in the elderly. Dependence can supervene on long-term use, occasionally with dose escalation. The benzodiazepines are now recognised as major drugs of abuse and addiction. Other drug and non-drug therapies are available and have a superior risk benefit ratio in long-term use. It is concluded that benzodiazepines should be reserved for short-term use--up to 4 weeks--and in conservative dosage.
