Genetic variants of the NOTCH3 gene in migraine--a mutation analysis and association study.

Mutations in the NOTCH3 gene cause cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Exons 3 and 4 are mutation hotspots. Migraine is a clinical hallmark of CADASIL.

Botulinum toxin A in the prophylactic treatment of migraine--a randomized, double-blind, placebo-controlled study.

Botulinum toxin A has been suggested to be effective in the prophylactic treatment of migraine. However, only very few randomized, double-blind, placebo-controlled studies are available. We designed such a study with a specific focus on different injection sites.

Prevention of AIDS dementia by HAART does not depend on cerebrospinal fluid drug penetrance.

The impact of the cerebrospinal fluid (CSF) penetrance properties of different highly active antiretroviral therapy (HAART) regimes on cognitive processing in AIDS dementia is still undetermined. We therefore designed a retrospective cross-sectional and prospective longitudinal analysis of event-related potentials in HIV-infected patients with different combinations of HAART or without antiretroviral treatment. A total of 353 consecutive patients without secondary CNS manifestation of HIV infection were enrolled in the cross-sectional study and 135 consecutive patients without secondary CNS manifestations of HIV infection were enrolled in the longitudinal study.

Headache associated with sexual activity: demography, clinical features, and comorbidity.

Objective: S: To provide data on the demography, clinical features, and comorbidity of headache associated with sexual activity (HSA).

Methods: Between 1996 and 2001, 51 patients with the diagnosis of HSA were questioned using a structured interview.

Results: The mean age at onset was 39.

The association between migraine and juvenile stroke: a case-control study.

Background: Several studies suggest an association between migraine and juvenile stroke. Because of some shortcomings, we designed another case-control study of a homogenous group of patients with juvenile cerebral ischemia. This study is part of a larger German epidemiological research project on the association of migraine with cerebrovascular disease.

Hypnic headache - the first German cases including polysomnography.

We report the first four German cases of hypnic headache according to the criteria suggested in the literature. Furthermore, we present the results of polysomnography in two theses cases with hypnic headache occurring during REM sleep. In one case, hypnic headache was also associated with periodic limb movements.
