Learn about epilepsy stages, symptoms and treatment for this disorder of the brain's electrical system. Epileptic seizures cause brief impulses in movement, behavior, sensation or awareness that may cause brain damage. Epilepsy is a group o These are known causes, common risk factors, and seizure triggers. These are known causes, common risk factors, and seizure triggers. Because "epilepsy" is actually an umbrella term for a group of neurological disorders, it can have many ca 15689359), myoclonic epilepsy myopathy sensory ataxia (MEMSA) (MedGen UID: 897191) and ataxia neuropathy spectrum (ANS) (MedGen UID: 375302).

Genetics of Myoclonic epilepsy myopathy sensory ataxia Genetic Changes : MEMSA is caused by mutations in the POLG gene. This gene provides instructions for making one part, the alpha subunit, of a protein called polymerase gamma (pol gamma). Myoclonic epilepsy, myopathy and sensory ataxia (MEMSA) represents a disorder previously referred as spinocerebellar ataxia with epilepsy (SCAE).3 MEMSA is most frequently due to POLG1 mutations. 38 MEMSA is clinically characterized by ataxia, myoclonic epilepsy, and myopathy.

Two daughters had lactic acidosis and myoclonic epilepsy, mild dementia, ataxia, weakness and sensory neuropathy.

It may be a normal phenomenon, as in the so-called ‘sleep starts’. When pathological, myoclonus is a symptom of a broad range of neurological and systemic diseases. The phenotype varies widely, even within the same family, and can include myopathy, seizures, and hearing loss, but the common clinical feature appears to be sensory ataxia (review by Milone and Massie, 2010). Myoclonic epilepsy with ragged-red fibres (MERRF) is most commonly caused by the m.8344A > G mutation in MTTK, but can be caused by any one of 13 mDNA-located genes and one nDNA-located gene. Mean age of onset is in the 30s but a third present in childhood.
