Neurology. Oromandibular dystonia (OMD) is an uncommon focal neurological condition affecting the jaws, face, and mouth. [1] Oromandibular dystonia is characterized by involuntary spasms of the tongue, jaw, and mouth muscles that result in bruxism, or grinding of the teeth, and jaw closure. These conditions frequently lead to secondary dental ...
Chattering teeth is a bodily function in animals that occurs primarily in response to cold; the jaw muscles begin to shiver leading teeth to crash together. It may also occur as a result of bruxism where emotional stress causes the jaw movements. Certain medications can lead to teeth chattering as a side effect, especially antipsychotics and ...
Meige's syndrome is a type of dystonia. It is also known as Brueghel's 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 Meige's Syndrome named after Henri Meige, [1] the French neurologist ...
Bruxism is excessive teeth grinding or jaw clenching. It is an oral parafunctional activity; [ 1 ] i.e., it is unrelated to normal function such as eating or talking. Bruxism is a common behavior; the global prevalence of bruxism (both sleep and awake) is 22.22%. [ 2 ] Several symptoms are commonly associated with bruxism, including aching jaw ...
Overuse of an affected hand or limb can activate symptoms including numbness, spasm, and painful cramping. [10] Symptoms and progression of the disease can vary. Involuntary grinding of teeth and squinting are prevalent and often go unnoticed by the person affected. Breathing can be affected in some, as can hearing, vision, and neck and ...
Signs and symptoms of temporomandibular joint disorder vary in their presentation. The symptoms will usually involve more than one of the various components of the masticatory system, muscles, nerves, tendons, ligaments, bones, connective tissue, or the teeth. [23] The three classically described, cardinal signs and symptoms of TMD are: [11] [24]
Atypical trigeminal neuralgia (ATN), or type 2 trigeminal neuralgia, is a form of trigeminal neuralgia, a disorder of the fifth cranial nerve. This form of nerve pain is difficult to diagnose, as it is rare and the symptoms overlap with several other disorders. [1] The symptoms can occur in addition to having migraine headache, or can be ...
The trigeminal nerve is a paired cranial nerve that has three major branches: the ophthalmic nerve (V 1), the maxillary nerve (V 2), and the mandibular nerve (V 3). One, two, or all three branches of the nerve may be affected. Trigeminal neuralgia most commonly involves the middle branch (the maxillary nerve or V 2) and lower branch (mandibular ...
