2010-05-05 · MERRF (Myoclonus Epilepsy with Ragged-Red Fibers) syndrome is an extremely rare disorder that begins in childhood and affects the nervous system and skeletal muscle as well as other body systems. The distinguishing feature in MERRF is myoclonus, consisting of sudden, brief, jerking spasms that can affect the arms and legs or the entire body. We report myoclonic epilepsy with ragged-red fibers (MERRF) syndrome in a Chinese family with confirmed mitochondrial DNA point mutation. Six members of the family including the grandmother, two siblings, and three grandchildren were affected. Myoclonic epilepsy with ragged-red fibers (MERRF) is a neurological disorder that is characterized by muscle twitches, weakness and progressive stiffness that affects numerous muscles of the body. Patients with MERRF can additionally exhibit recurrent seizures, difficulty coordinating movements, peripheral neuropathy and the slow deterioration of intellectual function ( 1 ).

2016-03-16 Myoclonic Epilepsy with Ragged Red Fibers (MERRF) is a multisystem mitochondrial disease.1 MERRF typically presents with myoclonus (brief, involuntary twitching of a muscle or a group of muscles), followed by generalized epilepsy, ataxia (lack of coordination of muscle movements), weakness, and dementia.1 Ragged red fibers Myoclonic epilepsy associated with ragged red fibers (MERRF) is a rare mitochondrial disorder. Diagnostic criteria for MERRF include typical manifestations of the disease: myoclonus, generalized epilepsy, cerebellar ataxia and ragged red fibers (RRF) on muscle biopsy.

Yet with the different types of mitochondrial myopathies, it may be difficult Myoclonus epilepsy with ragged-red fibers (MERRFs), an inherited mitochondrial disorder, has characteristic morphological changes of ragged-red fibers (RRFs) in muscle biopsy, in the absence of which mitochondrial etiology is usually not considered in patients with phenotypes suggestive of MERRF. In these circumstances, MERRF can only be diagnosed using genetic analyses.

Myoclonic Epilepsy with Ragged Red Fibers (MERRF) is a multisystem mitochondrial disease.1 2016-02-20 · All mitochondrial diseases have myopathies with → Blotchy red muscle fibers (on Gomori-Trichrome stain) & Red ragged fibers 1.

Epilepsy is a chronic neurological condition in which a person has recurrent seizures. A seizure is an abnormal surge of electrical activity in the brain that results in a temporary disturbance of motor, sensory, or mental function. There a

Other features associated with MERRF include cerebellar ataxia, myopathy, cardiac arrhythmia, sensorineural hearing loss, optic atrophy, and dementia. MERRF syndrome (or myoclonic epilepsy with ragged red fibers) is a mitochondrial disease. It is extremely rare, and has varying degrees of expressivity owing to heteroplasmy. MERRF syndrome affects different parts of the body, particularly the muscles and nervous system. MERRF (Myoclonus Epilepsy with Ragged-Red Fibers) syndrome is an extremely rare disorder that begins in childhood and affects the nervous system and skeletal muscle as well as other body systems.

Conventional brain MR imaging showed atrophy of the superior cerebellar peduncles and the cerebellum in all patients and brain stem atrophy in 2 patients. In diffusion tensor analysis, fractional anisotropy of MERRF (Myoclonic Epilepsy with Ragged Red Fibers) syndrome is a mitochondrial encephalomyopathy characterized by myoclonic seizures.
