Verapamil for severe hyperkinetic movement disorders.

The use of verapamil in three cases of severe hyperkinetic movement disorders resulted in dramatic improvement in patients who had been refractory to many other treatments over a prolonged period. A videotape illustration of one of the patients is provided. The mechanism of action and evidence of efficacy of calcium-channel blockers for abnormal movements are discussed.

Erotomania in a brain-damaged male.

A 31-year-old male presented to a neuropsychiatric service for the first time with an erotomatic delusion among other symptoms. He had suffered significant brain damage several times in the past and experienced a recent loss. After extensive evaluation, a trial of haloperidol resulted in some improvement. However, the erotomanic delusion remained unchanged.

Clinical and genetic studies of fatal familial insomnia.

We report a 42-year-old man who, for 8 months, had intermittent motor abnormalities and mild difficulty falling asleep. A diagnosis of fatal familial insomnia (FFI) became evident over the next 6 months when he developed progressive insomnia, myoclonus, sympathetic hyperactivity, and dementia. The amyloid or prion protein (PrP) genotype showed features typically seen in FFI, with a 178Asn mutation and a 129Met polymorphism. There was also a deletion of one octapeptide repeat, suggesting that the association of 178Asn mutation with the 129Met polymorphism is not due to "founder effect." Western immunoblot showed a trace of protease-resistant PrP in the thalamus--which had the most significant neuronal loss and gliosis--a moderate amount of PrP in the fronto-temporal area, and no detectable protein elsewhere in the brain. Endocrine studies showed that a circadian modulation of hormonal levels could be maintained despite a near-total absence of sleep. Administration of gamma-hydroxybutyrate induced a remarkable increase in slow-wave sleep.

Leuprolide acetate for exhibitionism in Huntington's disease.

We treated a patient with Huntington's disease and exhibitionism using leuprolide acetate (Lupron Depot, TAP Pharmaceuticals), a gonadotropin-releasing hormone agonist. The result was elimination of his deviant sexual behavior with few side effects. This regimen may be a safe and effective pharmacological treatment of the paraphilias. The occurrence of paraphilias in basal ganglia disorders is reviewed.
