What are benign fasciculations?

Benign fasciculation syndrome is persistent muscle twitching, tingling, or numbness in one or more muscles. Muscle twitches are usually not a cause for concern. However, many people still get them checked out by a doctor to avoid serious complications.

What can cause benign fasciculations?

Causes of benign fasciculation syndrome

  • a stressful time.
  • trauma.
  • anxiety or depression.
  • high-intensity, strenuous exercise.
  • fatigue.
  • drinking alcohol or caffeine.
  • smoking cigarettes.
  • a recent viral infection.

Can benign fasciculations be constant?

The main symptom of benign fasciculation syndrome is focal or widespread involuntary muscle activity (fasciculation). The benign twitches usually have a constant location. Other common symptoms are generalized fatigue or weakness, paraesthesia or numbness, and muscle cramping or spasms.

Do benign fasciculations go away?

Conclusions: Despite its benign natural history, BFS is a source of high morbidity for patients, both physically and psychologically. At two years, fasciculations resolved in only 5% of patients. Most still experienced subjective weakness, sensory symptoms, and cramps.

Can stress cause benign fasciculations?

Stress, depression, and anxiety are all known to increase fasciculation potential. These twitches are most often diagnosed as benign fasciculation syndrome, or BFS. This term captures a range of specific causes of involuntary twitches and muscle spasms that do not have a serious or even a known cause.

Can fasciculations last for months?

Fasciculations or twitching of muscles may appear randomly or may persist in one muscle for an extended period of time. Fasciculations will be most noticeable when the body is at rest. There may be associated pain in the affected muscle. The disorder is often confused with ALS, or Lou Gehrig’s disease.

What is the difference between fasciculations and twitches?

“Fasciculations occur when innervation from the peripheral nervous system to the muscle is not working correctly and a muscle is triggered involuntarily, causing it to twitch,” says Dr. Ondo. “This is very common and these fasciculations usually go unnoticed, but in some cases, people do feel the muscle twitch.”

What do fasciculations indicate?

Fasciculations indicate denervation of muscle caused by a lesion of the motor neuron at any site from the anterior horn cell to the terminal motor axon. Fasciculation is most striking in anterior horn cell disease.
