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.
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 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 ...
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 ...
Myoclonus. Myoclonus is a brief, involuntary, irregular (lacking rhythm) twitching of a muscle, a joint, or a group of muscles, different from clonus, which is rhythmic or regular. Myoclonus (myo- "muscle", clonus "spasm") describes a medical sign and, generally, is not a diagnosis of a disease. It belongs to the hyperkinetic movement disorders ...
Essential tremor (ET), also called benign tremor, familial tremor, and idiopathic tremor, is a medical condition characterized by involuntary rhythmic contractions and relaxations (oscillations or twitching movements) of certain muscle groups in one or more body parts of unknown cause. [6] It is typically symmetrical, and affects the arms ...
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.
In its traditional manifestation, chronic inflammatory demyelinating polyneuropathy is characterized by symmetric, progressive limb weakness and sensory loss, which typically starts in the legs. Patients report having trouble getting out of a chair, walking, climbing stairs, and falling. Problems with gripping objects, tying shoe laces, and ...
