Understanding MERRF
MERRF syndrome is a rare disorder that impacts various bodily systems. Here's a more detailed look:
Key Aspects of MERRF
- Neurological Impact: MERRF affects the nervous system, leading to symptoms such as myoclonus (sudden, involuntary muscle jerks) and seizures.
- Muscle Involvement: The syndrome also affects skeletal muscles, which can result in weakness and fatigue. The term "ragged-red fibers" refers to the appearance of muscle tissue under a microscope.
- Systemic Disorder: MERRF can affect various other systems in the body.
Onset and Progression
- Variable Onset: MERRF can manifest during childhood, adolescence, or even adulthood.
- Normal Development Initially: Individuals with MERRF typically experience normal development early in life before symptoms appear.
