Experiments were carried out in order to further delineate the pathophysiology of the fall of plasma 5-hydroxytryptamine (5-HT) during a migraine attack. Platelets from normal subjects were incubated with 14C-labelled 5-HT, and the release of 5-HT was measured following exposure of these platelets to plasma taken from migraine patients during an attack or at headache-free intervals. Plasma taken during attacks released significantly more 5-HT. It is concluded that factor(s) exist in the serum during migraine attacks, which can cause 5-HT release from normal platelets. The identification of this factor may be important.

Sodium valproate- a salt of valproic acid (VPA), is an anticonvulsant used in the treatment of epilepsy and a range of psychiatric conditions that include panic attacks, anxiety, post-traumatic stress, migraine and bipolar disorder etc. VPA can cause direct damage to many tissues due to accumulation of toxic metabolites. Nowadays, phytochemicals are amongst the best options for the treatment of diseases.

Familial hemiplegic migraine type 2 results from pathogenic variants in the gene, which encodes for a catalytic subunit of sodium/potassium ATPase. This extremely rare autosomal dominant disorder manifests with a spectrum of symptoms, most commonly pure hemiplegic phenotype, epilepsy, and/or intellectual disability. In this study, we detail the clinical features and genetic analysis of nine patients from a large family spanning four generations, with all carrying a previously unreported likely pathogenic variant, p.

Neuronal intranuclear inclusion disease (NIID) is a rare progressive neurodegenerative disease with a characteristic pathological feature of eosinophilic hyaluronan inclusions in the nervous system and internal organs. The identification of GGC-repeat expansions in the Notch 2 N-terminal like C (NOTCH2NLC) gene facilitates the accurate diagnosis of NIID. Due to its rareness and high clinical heterogeneity, the diagnosis of NIID is often delayed or missed.

Introduction: It is largely accepted that migraine with aura (MA) is caused by cortical spreading depression (CSD) and that migraine without aura (MO) is not. This is mostly based on old studies of regional cerebral blood flow (rCBF) and studies of vascular responses. These studies are partly forgotten today and may, therefore, be worthwhile reviewing.
