We report on a 30-year-old patient with advanced cerebellar degeneration due to SCA2. He presented with severe myoclonus, which was resistant to conventional therapy and dramatically improved after administration of 12-18 gm/die piracetam. Piracetam may be considered in the treatment of refractory myoclonus in spinocerebellar degenerations.

Objectives: Although myoclonus less than or equal to 72 hours after cardiac arrest (CA) is often viewed as a single entity, there is considerable heterogeneity in its clinical and electrophysiology characteristics, and its strength of association with outcome. We reviewed definitions, electroencephalogram, and outcome of myoclonus post-CA to assess the need for consensus and the potential role of electroencephalogram for further research.

Etomidate, an intravenous hypnotic used for anaesthesia and critical care, is known for its undesirable side effects, including pain on injection, myoclonus, and adrenocortical depression. Despite its continued clinical use because of its haemodynamic stability and rapid onset and offset of effect, alternatives like propofol, ketamine, and remimazolam offer fewer drawbacks. Recent efforts to improve etomidate through chemical modifications, such as methoxyethyl etomidate hydrochloride (ET-26), have shown limited success, with persistent issues like involuntary muscle movements and adrenocortical suppression.

Background: Etomidate can induce myoclonus with an incidence of 50 ~ 85% during anesthesia induction. Dexamethasone, as a long-acting synthetic glucocorticoid, has neuroprotective effects. However, the effects of dexamethasone on the etomidate-induced myoclonus remain uncertain.

Objective: North Sea Progressive Myoclonus Epilepsy (NS-PME) is a rare genetic disorder characterized by ataxia, myoclonus and seizures with a progressive course. Although the cause of NS-PME is known, namely a homozygous mutation in the GOSR2 gene (c.430 G>T; p.
