BENIGN ADULT FAMILIAL MYOCLONIC EPILEPSY

Alternate names

BENIGN ADULT FAMILIAL MYOCLONIC EPILEPSY Is also known as adcme, bafme, benign adult familial myoclonic epilepsy 1, autosomal dominant cortical myoclonus and epilepsy, fame, cortical myoclonic tremor with epilepsy, familial, 1, familial adult myoclonic epilepsy, benign adult familial myoclonus epilepsy, familial cortica

Description

Benign adult familial myoclonic epilepsy (BAFME) is an inherited epileptic syndrome characterized by cortical hand tremors, myoclonic jerks and occasional generalized or focal seizures with a non-progressive or very slowly progressive disease course, and no signs of early dementia or cerebellar ataxia.

Most common symptoms of BENIGN ADULT FAMILIAL MYOCLONIC EPILEPSY

  • Intellectual disability
  • Seizures
  • Ataxia
  • Tremor
  • Headache

EPILEPSY, FAMILIAL ADULT MYOCLONIC, 2; FAME2

Alternate names

EPILEPSY, FAMILIAL ADULT MYOCLONIC, 2; FAME2 Is also known as adcme, bafme2, cortical myoclonic tremor with epilepsy, familial, 2, benign adult familial myoclonic epilepsy 2, cortical myoclonus and epilepsy, autosomal dominant, fcmte2

Description

Familial adult myoclonic epilepsy-2 is an autosomal dominant neurologic disorder characterized by rhythmic myoclonic jerks of cortical origin. Some affected individuals have generalized tonic-clonic seizures, and rare patients show cognitive decline (summary by De Fusco et al., 2014).For a phenotypic description and a discussion of genetic heterogeneity of familial adult myoclonic epilepsy, see FAME1 (OMIM ).

Most common symptoms of EPILEPSY, FAMILIAL ADULT MYOCLONIC, 2; FAME2

  • Intellectual disability
  • Seizures
  • Ataxia
  • Cognitive impairment
  • Tremor
