15 Dystonia Varieties That Will Spin Your Brain Around
12. Oromandibular Dystonia (OMD)

Oromandibular dystonia specifically targets the muscles of the jaw, tongue, and mouth. This can manifest as involuntary opening, closing, or deviation of the jaw, tongue protrusion, or lip retraction. Eating, speaking, and swallowing become incredibly difficult, impacting daily life and nutrition. OMD can appear alone or as part of more complex dystonias like Meige syndrome (which combines it with blepharospasm). The constant muscle contractions are often painful, and the visible nature of the symptoms can also lead to significant social challenges for affected individuals.
