Twitching

Twitching refers to small, local, involuntary muscle movement, similar to fasciculations. It is often associated with a long-term motor disorder known as twitching syndrome, but may also occur in healthy individuals.

Causes

Twitching can be caused by a variety of conditions, including stress, anxiety, fatigue, and caffeine overuse. It can also be a symptom of certain neurological conditions, such as ALS, MS, or Parkinson's disease. In many cases, the cause of twitching is unknown.

Diagnosis

Diagnosis of twitching is typically based on a physical examination and a detailed medical history. In some cases, further testing may be required, such as EMG or MRI scans.

Treatment

Treatment for twitching depends on the underlying cause. If the twitching is caused by stress or anxiety, relaxation techniques such as meditation or yoga may be helpful. If the twitching is caused by a neurological condition, medication or other treatments may be necessary.
