Meiges syndrome is a type of dystonia. It is also known as Brueghels syndrome and oral facial dystonia. It is actually a combination of two forms of dystonia, blepharospasm and oromandibular dystonia (OMD). When OMD is combined with blepharospasm, it may be referred to as Meiges Syndrome named after Henri Meige, the French neurologist who first described the symptoms in detail in 1910. The symptoms usually begin between the ages of 30 and 70 years old and appear to be more common in women than in men (2:1 ratio). The combination of upper and lower dystonia is sometimes called cranial-cervical dystonia. The incidence is about one case in 20,000 people. Presentation
The main symptoms involve involuntary blinking and chin thrusting. Some patients may experience excessive tongue protrusion, squinting, light sensitivity, muddled speech, or uncontrollable contraction of the platysma muscle. Some Meiges patients also have "laryngeal dystonia" (spasms of the larynx). Blepharospasm may lead to embarrassment in social situations, and oromandibular dystonia can affect speech, making it difficult to carry on the simplest conversations. This can cause difficulty in both personal and professional contexts, and in some cases may cause patients to withdraw from social situations.The condition tends to affect women more frequently than men.
