Roller coaster migraine: an underreported injury?

A 28-year-old woman presented with severe headache, sleep problems, memory problems, and irritability 2 months after a violent roller coaster ride. She was diagnosed with posttraumatic migraine, and intravenous dihydroergotamine resolved her symptoms. Imaging studies, electroencephalogram, and visual and auditory evoked responses were normal. Imipramine, divalproex sodium, and propranolol were prescribed to prevent the headaches from recurring and dihydroergotamine nasal spray was prescribed for breakthrough headaches. We consider the many short but significant brain insults delivered during the roller coaster ride a critical factor in triggering this instance of posttraumatic migraine, which while unmanaged was a source of significant disability for the patient.

Case reports: sudden worsening of cluster headache: A signal of aneurysmal thrombosis and enlargement.

We report a 55-year-old man presenting with symptoms of cluster headache, including throbbing pain behind the left eye, tearing, and rhinorrhea. Magnetic resonance imaging and magnetic resonance angiography revealed no abnormalities. Two days of intravenous dihydroergotamine resolved his pain. His headaches were somewhat relieved with a treatment regimen of 100 mg of imipramine each night, 40 mg of propranolol twice a day, 250 mg of divalproex three times a day, and dihydroergotamine nasal spray for breakthrough headaches. Two months later, the severity of his pain increased dramatically. Repeat imaging revealed a large thrombosed left posterior communicating artery aneurysm. Following obliterative surgery, his headaches are infrequent and mild and resemble tension headaches. Dramatic changes in headache characteristics can be an indicator of aneurysmal enlargement and thrombosis. This case illustrates the importance of repeat imaging when a patient's headache significantly worsens.

Use of dihydroergotamine in patients with postconcussion syndrome.

The experience with 34 patients who came to the Shreveport Headache Clinic for treatment of postconcussion headache is reviewed. All had been suffering from postconcussion (posttraumatic) syndrome for periods ranging from one day to more than three years, and all displayed, in addition to headache, at least three other symptoms characteristic of the syndrome, eg, memory problems, impaired concentration, sleep problems, dizziness, and anxiety. After initial evaluation at the clinic, the patients were admitted to Willis Knighton Medical Center and treated with repetitive administration of intravenous dihydroergotamine (DHE) and metoclopramide. A good to excellent overall response to DHE therapy was achieved by 88% (29) of the patients. The percentages and numbers of patients obtaining good to excellent relief of selected key symptoms were: 85% (28) - headache, 91% (30) - memory problems, 94% (31) - sleep problems, and 88% (29) - dizziness. DHE was well-tolerated, and no serious or unexpected adverse reactions were reported. The most frequently reported adverse reactions were mild nausea and brief worsening of headache.

Chorea gravidarum in systemic lupus erythematosus.

A case of chorea gravidarum in a patient with systemic lupus erythematosus (SLE) is described. Review of the literature on chorea gravidarum suggests that SLE may be a more common cause than previously reported. Treatment of chorea gravidarum in SLE patients is discussed.
