Cerebral oedema in episodic ataxia.
We report a patient with episodic ataxia (presumably of type 2) who developed cerebral oedema secondary to a common infection (presumably viral). Cerebral oedema may be a part of the clinical spectrum of familial episodic ataxia and argues for an overlap with hemiplegic migraine. It is suggested to consider a diagnosis of episodic ataxia or familial hemiplegic migraine in catastrophic reactions...
متن کاملFamilial episodic ataxia type II.
The familial episodic ataxia type II is a rare, dominantly inherited disease characterized by episodes of ataxia of early onset, often with completely normal cerebellar function between attacks. We report a family with affected members who had features of episodic ataxia type II and cerebellar atrophy on MRI imaging. All the affected members were successfully treated with acetazolamide, a carbo...
متن کاملExonic deletions of FXN and early-onset Friedreich ataxia.
BACKGROUND Friedreich ataxia (FA) is the most frequent type of autosomal recessive cerebellar ataxia, occurring at a mean age of 16 years. Nearly 98% of patients with FA present with homozygous GAA expansions in the FXN gene. The remaining patients are compound heterozygous for an expansion and a point mutation. Patients who are compound heterozygous for an exonic deletion and an expansion are ...
متن کاملSpinocerebellar ataxia type 6 and episodic ataxia type 2 in a Korean family.
Spinocerebellar ataxia type 6 (SCA6), episodic ataxia type 2 (EA2) and familial hemiplegic migraine (FHM) have been known as allelic disorders, which are caused by the alteration of the alpha1A voltage-dependent calcium channel subunit. Expansions of the CAG repeat in the CACNA1A gene on the short arm of the chromosome 19 induce SCA6, and point mutations in the same gene are responsible for EA2...
متن کاملWhole-exome sequencing as a diagnostic tool in a family with episodic ataxia type 1.
Complex neurologic phenotypes are inherently difficult to diagnose. Whole-exome sequencing (WES) is a new tool in the neurologist's diagnostic armamentarium. Whole-exome sequencing can be applied to investigate the "diagnostic odyssey" cases. These cases involve patients with rare diseases that likely have a genetic etiology but have failed to be diagnosed by clinical evaluation and targeted ge...
