Prognosis. Good-Excellent. Benign fasciculation syndrome (BFS) is characterized by fasciculation (twitching) of voluntary muscles in the body. [1] The twitching can occur in any voluntary muscle group but is most common in the eyelids, arms, hands, fingers, legs, and feet. The tongue can also be affected.
A fasciculation, or muscle twitch, is a spontaneous, involuntary muscle contraction and relaxation, involving fine muscle fibers. [1] They are common, with as many as 70% of people experiencing them. [1] They can be benign, or associated with more serious conditions. [1] When no cause or pathology is identified, they are diagnosed as benign ...
Somatic symptom disorder, also known as somatoform disorder, or somatization disorder, is defined by one or more chronic physical symptoms that coincide with excessive and maladaptive thoughts, emotions, and behaviors connected to those symptoms. The symptoms are not deliberately produced or feigned, and they may or may not coexist with a known ...
Neuromyotonia is a type of peripheral nerve hyperexcitability. Peripheral nerve hyperexcitability is an umbrella diagnosis that includes (in order of severity of symptoms from least severe to most severe) benign fasciculation syndrome, cramp fasciculation syndrome, neuromyotonia and morvan's syndrome. Some doctors will only give the diagnosis ...
Cramp fasciculation syndrome (CFS) is a rare [1] peripheral nerve hyperexcitability disorder. It is more severe than the related (and common) disorder known as benign fasciculation syndrome ; it causes fasciculations , cramps, pain, fatigue, and muscle stiffness similar to those seen in neuromyotonia (another related condition). [ 2 ]
A neuromuscular disease is any disease affecting the peripheral nervous system (PNS), [ a ] the neuromuscular junctions, or skeletal muscles, all of which are components of the motor unit. [ 4 ] Damage to any of these structures can cause muscle atrophy and weakness. Issues with sensation can also occur. Neuromuscular diseases can be acquired ...
Specialty. Neurology, ophthalmology. Blepharospasm is a neurological disorder characterized by intermittent, involuntary spasms and contractions of the orbicularis oculi (eyelid) muscles around both eyes. [1][2][3][4] These result in abnormal twitching or blinking, and in the extreme, sustained eyelid closure resulting in functional blindness.
A fasciculation potential is an involuntary activation of a motor unit within the muscle, sometimes visible with the naked eye as a muscle twitch or by surface electrodes. Fibrillations, however, are detected only by needle EMG, and represent the isolated activation of individual muscle fibers, usually as the result of nerve or muscle disease.
