Muscle Twitching: Clinical Meaning

Epilepsy

Epilepsy is a neurological disorder characterized by recurrent, unprovoked seizures resulting from abnormal electrical activity in the brain. It affects people of all ages and can be managed with medication in most cases.

Amyotrophic Lateral Sclerosis (ALS)

ALS is a rapidly progressive neurodegenerative disease affecting motor neurons, causing progressive muscle weakness, paralysis, and respiratory failure. Most patients die within 3-5 years of diagnosis; riluzole and edaravone modestly slow progression.

Huntington's Disease

Huntington's disease is a hereditary neurodegenerative disorder caused by a CAG repeat expansion in the HTT gene, causing progressive motor, cognitive, and psychiatric deterioration. Symptoms typically begin in mid-adulthood with no disease-modifying treatment.

Essential Tremor

Essential tremor is the most common movement disorder, causing involuntary rhythmic shaking, most often affecting the hands during purposeful movement. It is distinct from Parkinson's tremor; propranolol and primidone are first-line treatments.

Magnesium Deficiency

Magnesium deficiency affects an estimated 10-30% of the population. Magnesium is involved in over 300 enzymatic reactions in the body, making deficiency wide-ranging in effects.
