Myoclonic Epilepsy, Juvenile - Pathology
Research News and Information
Definition of 'Myoclonic Epilepsy, Juvenile'A disorder characterized by the onset of myoclonus in adolescence, a marked increase in the incidence of absence seizures (see EPILEPSY, ABSENCE), and generalized major motor seizures (see EPILEPSY, TONIC-CLONIC). The myoclonic episodes tend to occur shortly after awakening. Seizures tend to be aggravated by sleep deprivation and alcohol consumption. Hereditary and sporadic forms have been identified.

Voxel-based morphometry evaluation of patients with photosensitive juvenile myoclonic epilepsy.
28 Jun 2009 
We aim to investigate structural brain abnormalities in juvenile myoclonic epilepsy (JME) patients with photosensitivity (PS). Sixty JME patients, 19 (32%) of whom were photosensitive, were submitted to 1.5T magnetic resonance voxel-based ... Read more...
9 Apr 2009 Studies involving juvenile myoclonic epilepsy (JME) patients have demonstrated an elevated prevalence of cluster B personality disorders (PD) characterized as emotional instability, immaturity, unsteadiness, lack of discipline, and rapid mood ... Read more...
Digenic mutations in severe myoclonic epilepsy of infancy.
7 Apr 2009 The clinical features of severe myoclonic epilepsy of infancy (SMEI) resemble those of mitochondrial diseases, although most patients have the sodium channel (SCN1A) mutation. We describe a patient with SMEI and enlarged muscle mitochondria ... Read more...
