Geniospasm
Geniospasm
Geniospasm (pronounced: jen-ee-oh-spaz-uhm) is a rare medical condition characterized by episodic, involuntary movements of the chin and lower lip.
Etymology
The term "Geniospasm" is derived from the Greek words "genio" meaning chin and "spasm" meaning sudden, involuntary muscle contraction.
Definition
Geniospasm, also known as Hereditary Geniospasm, is a movement disorder that primarily affects the muscles of the lower lip and chin. The condition is characterized by episodes of rapid, involuntary contractions (spasms) of these muscles. These episodes can last from a few seconds to a few minutes.
Symptoms
The primary symptom of Geniospasm is the involuntary twitching or trembling of the chin and lower lip. This can occur spontaneously or can be triggered by stress, fatigue, or extreme emotions. In some cases, the spasms may spread to the muscles of the neck or upper lip.
Causes
Geniospasm is believed to be a genetic condition, passed down through families in an autosomal dominant pattern. This means that an affected person has a 50% chance of passing the disorder to each of their children. The exact gene responsible for Geniospasm has not yet been identified.
Treatment
Treatment for Geniospasm primarily involves managing the symptoms. Medications such as Benzodiazepines and Anticonvulsants may be used to control the muscle spasms. In severe cases, Botox injections or surgery may be considered.
