Fasciculation

Neurology
The fasciculation is the tendency that have the Neurites under development to grow along neurites preexistent.
Physiology
The fasciculation is a contraction involuntary and isolated from a fascicule of muscle fibers, independently of the close beams which them, remain at rest. Visible through the Skin, they are often noticed with the periphery of the eye and are regularly taken, by error, for the beat of a Nerf.
It does not cause any segmentary movement except sometimes on the level of the Doigt S.
Physiopathology
The causes of this symptom are numerous although very often benign (one speaks about BFS for Benign Fasciculation Syndrom ) even if they appear in certain neurological diseases such as:
- the Disease of Kugelberg Welander,
- the Disease of Kennedy.
- the Disease of Creutzfeldt-Jacob.
- the Disease of Machado-Joseph.
- the Syringomyélie.
- the Syndrome of Isaac-Mertens also called Neuro-myotonie.
- the borreliose (Disease of Lyme)
- the amyotrophic side Sclerosis
