Meige Syndrome

Excerpt

Meige syndrome is a focal dystonic movement disorder characterized by blepharospasm (double eyelid spasm) and oromandibular dystonia. Dystonia involves abnormal involuntary posturing or body movements resulting from sustained muscle contractions, often arising from neurological or medical causes. In 1910, Dr Henry Meige, a French neurologist, observed abnormal contractions of midline facial muscles, including involuntary eyelid closure, in approximately 10 patients. He initially termed this condition "spasm facial median." These patients also demonstrated a similar clinical manifestation in the muscles of the jaw and oropharynx.

In 1972, Dr George Paulson introduced the term "Meige syndrome" to describe patients experiencing facial muscle spasms, notably blepharospasm and dystonia of oromandibular muscles. After several years, Gilbert introduced the term "Brueghel syndrome" to describe a case of jaw dystonia, distinguished from Meige syndrome by the absence of blepharospasm.

The use of the term "Meige syndrome" for a type of dystonia based on historical perspectives can be problematic and confusing, especially considering that this physician did not suffer from the syndrome and was not the first doctor to describe this type of dystonia. Medical associations, including the Council of Science Editors, have discouraged using possessive forms of eponyms. Moreover, Meige syndrome is sometimes confused with Meigs' syndrome, which is unrelated to dystonia and defines the clinical presentation found in a specific type of benign ovarian tumor.

Although the exact pathophysiology of Meige syndrome is unknown, it is believed to be related to abnormalities in the basal ganglia—a critical brain region essential for motor control. Dystonia is thought to result from dysfunction in neurotransmitter systems, particularly affecting dopamine and gamma-aminobutyric acid (GABA).

The course of Meige syndrome varies significantly from person to person. Symptoms typically begin gradually and may worsen over time, although they can also enter spontaneous remission or remain stable. The age of symptom onset may also differ. Some individuals experience symptoms in early adulthood, whereas others may not exhibit them until later in life. Managing and treating symptoms can be challenging due to their unpredictable nature and influence on day-to-day functioning.

The lower face and jaw are typically the initial areas to exhibit signs of Meige syndrome. These signs manifest as involuntary spasms of the muscles involved in speech, swallowing, and chewing. Eventually, dystonic movements can extend to the lips, tongue, cheeks, and neck muscles, among other parts of the face. In some cases, dystonia may extend to different parts of the body, resulting in generalized dystonia, while in others, it remains confined to the oromandibular region.
