The patient experience of illness, treatment, and change, during intensive community treatment for severe anorexia nervosa.

This study explores experiences of intensive community treatment, illness, and change among patients with severe anorexia nervosa (sAN), particularly seeking to understand the processes involved in change and inability to change. A qualitative design with purposive semi-stratified sampling, using semi-structured interviews and interpretive phenomenological analysis, investigated in detail the experiences of five participants. Participants all had sAN at the start of treatment and represented a spectrum of outcomes from deterioration to full recovery.

Genetic and functional characterisation of the P/Q calcium channel in episodic ataxia with epilepsy.

Mutations in CACNA1A, which encodes the principal subunit of the P/Q calcium channel, underlie episodic ataxia type 2 (EA2). In addition, some patients with episodic ataxia complicated by epilepsy have been shown to harbour CACNA1A mutations, raising the possibility that P/Q channel dysfunction may be linked to human epilepsy. We undertook a review of all published CACNA1A EA2 cases and this showed that 7% have epilepsy--representing a sevenfold increased epilepsy risk compared to the background population risk (P<0.

Premature stop codons in a facilitating EF-hand splice variant of CaV2.1 cause episodic ataxia type 2.

Premature stop codons in CACNA1A, which encodes the alpha(1A) subunit of neuronal P/Q-type (Ca(V)2.1) Ca(2+) channels, cause episodic ataxia type 2 (EA2). CACNA1A undergoes extensive alternative splicing, which contributes to the pharmacological and kinetic heterogeneity of Ca(V)2.

Mutations in the gene LRRK2 encoding dardarin (PARK8) cause familial Parkinson's disease: clinical, pathological, olfactory and functional imaging and genetic data.

We have established that the frequency of LRRK2 mutations in a series of 118 cases of familial Parkinson's disease is 5.1%. In the largest family with autosomal dominant, late-onset Parkinson's disease where affected subjects share a Y1699C missense mutation we provide a detailed clinical, pathological and imaging report.
