Raised levels of P/Q type voltage-gated calcium-channel (VGCC) antibodies were found in 16 (41%) of 39 patients with paraneoplastic cerebellar degeneration (PCD) and Hu antibodies were found in nine (23%). Seven of the 16 VGCC antibody-positive patients had Lambert-Eaton myasthenic syndrome (LEMS). Seven of 15 CSF samples had VGCC antibodies, with evidence(More)
We describe a new antibody, called anti-glial nuclear antibody (AGNA), in patients with paraneoplastic neurological syndromes (PNS) and small-cell lung carcinoma (SCLC). AGNA was initially identified in 24 sera of our archives by immunohistochemistry on rat cerebellum. AGNA positive sera showed a characteristic nuclear staining of the Bergmann glia in the(More)
We found voltage-gated potassium channel (VGKC) antibodies in 4 of 15 patients with limbic encephalitis (LE). Two patients with idiopathic LE had high VGKC antibody levels (>800 pM; controls <100 pM), that fell in parallel with a clinical response to immunotherapy. Two patients with lower VGKC antibodies (170 pM, 300 pM) had lung cancer (radiological(More)
The transient receptor potential (TRP) superfamily of non-selective cationic channels are involved in several processes plausibly relevant to migraine pathophysiology, including multimodal sensory and pain perception, central and peripheral sensitization, and regulation of calcium homeostasis. With the aim of identifying single nucleotide polymorphisms(More)
OBJECTIVE To apply genetic analysis of genome-wide association data to study the extent and nature of a shared biological basis between migraine and coronary artery disease (CAD). METHODS Four separate methods for cross-phenotype genetic analysis were applied on data from 2 large-scale genome-wide association studies of migraine (19,981 cases, 56,667(More)
OBJECTIVE To assess antibody levels against human herpesvirus type 6 (HHV-6), Epstein-Barr virus (EBV), and Chlamydia pneumoniae (CP) in serum from individuals in the early and late phase of MS. RESULTS A strong association was found between anti-HHV-6 immunoglobulin M antibodies and early MS (clinically isolated syndromes at high risk for MS, and short(More)
OBJECTIVES To analyze the trajectory to diagnosis and information provided in a series of cluster headache (CH) patients from five headache clinics. METHODS CH patients were asked to fill in an ad hoc questionnaire. RESULTS Seventy-five patients (mean age 41.5 years, 67 males) completed the questionnaire. Patients had visited during an average of 4.9(More)
Migraine without aura is the most common form of migraine, characterized by recurrent disabling headache and associated autonomic symptoms. To identify common genetic variants associated with this migraine type, we analyzed genome-wide association data of 2,326 clinic-based German and Dutch individuals with migraine without aura and 4,580 population-matched(More)
Encephalopathy associated with autoimmune thyroid disease is an underdiagnosed clinical condition. No specific disease marker exists and to date, imaging techniques have not proven useful. The disease is characterized by seizures, stroke-like events and psychiatric symptoms. Here, we present the report of a patient with encephalopathy associated with(More)
BACKGROUND Calcitonin gene-related peptide (CGRP) receptor antagonism is an approach to migraine therapy. The locus of action of antimigraine treatment is not resolved. The objective was to investigate CGRP receptors in the ventrolateral periaqueductal gray (vlPAG) involved in the modulation of trigeminovascular nociception by descending influences on(More)
