• Loss of Initiative

  Significant weight loss was reported in 3 out of 5 patients with eating dysfunction and OMD. Only patients with both OMD and OBL dyskinesias experienced weight loss. The weight loss ranged from 13–15 lbs (13.6% to 10.5% loss of initial body weight). [head-face-med.biomedcentral.com]

  Dystonia follows Parkinson's disease (a neurological movement disorder associated with bradykinesia, tremor, rigidity, and postural instability) and essential tremor (a common movement disorder characterized by involuntary, rhythmic oscillatory movements [sites.google.com]

• Rubral Tremor

  Patient distribution was as follows: Seven patients had chorea due to HD, 1 had tardive dystonia, 1 had oromandibular dystonia (OMD), 1 had post-ischemic hemidystonia, 1 had hemiballismus, and 1 patient had post-traumatic rubral tremor. dagger]) EPS [medical-dictionary.thefreedictionary.com]

Workup Patients should be evaluated for a family history of dystonia or the presence of other dystonias. [entokey.com]

• Acanthocytes

  Routine blood tests, as well as tests for serum copper, ceruloplasmin, and acanthocytes, yielded normal results. Video-EEG monitoring did not detect abnormalities. [elsevier.es]

After BoNT treatment, there was a significant reduction in the mean total OMDQ-25 score at 4 weeks (38.2 ± 17.6; p = 0.004), as well as at 8 weeks (39.6 ± 18.1; p = 0.008). [ncbi.nlm.nih.gov]

Oral agents remain one of the first-line medical treatments for OMD, and evaluation by a neurologist for consideration of such treatment is a prudent initial step. [entokey.com]

For example, patients with less than a 50% improvement on a 1 to 100 function rating scale were re-injected less than a month following their initial treatment. The overall median time between treatments was 3 months. [mdedge.com]

The prognosis is poor and the treatment is symptomatic. This paper describes a case of a 38-year-old woman referred for a locked left TMJ who was diagnosed as having an oromandibular dystonia. [ncbi.nlm.nih.gov]

Types of dystonia: The many types of dystonia are divided into separate groups because of their implications for treatment and prognosis. [hopkinsmedicine.org]

Prognosis What is my prognosis? If dystonia develops in childhood, particularly if it starts in the legs, then in many (but not all) cases it will spread to other parts of the body and become generalised. [brainfoundation.org.au]

Clinical characteristics, etiology of brain injury, and pattern of dystonia were analyzed. Patients with clinically significant CD and OMD were treated with BTx and followed for 12 weeks. [ncbi.nlm.nih.gov]

By definition, all cases of "dystonia plus" are secondary, although the etiology (eg, neuroleptics, Wilson disease, neuroacanthocytosis, trauma) may not always be obvious. [medlink.com]

Differential diagnosis of oromandibular dystonia and various etiologies were investigated. Neuroimaging studies revealed a left cerebellar infarction. [academiccommons.columbia.edu]

The etiology is unknown but in the idiopathic form is believed to be related to a neurotransmitter defect possible in the basal ganglia. About 20% of patients with brain injuries develop new onset cervical or oromandibular dystonias. [mussenhealth.us]

These results may be of value with regard to the conduct of multicenter epidemiologic and clinical studies on focal dystonias. [ncbi.nlm.nih.gov]

Epidemiology, clinical features, and etiology Oromandibular dystonia affects women more frequently than men and the prevalence was estimated to be 68.9 cases per 1 million Americans (for reviews see Bhidayasiri et al. [2006]). [cambridge.org]

In the present case history, treatment for OMD was started as soon as the diagnosis of jaw-closing OMD was established, and dental treatment intervention for preventing its development or progression was considered at the same time. [ncbi.nlm.nih.gov]

It prevents specific neurotransmitters from reaching the affected muscles, preventing spasms. Botulinum toxin is administered by injection. One dose usually lasts about 3 months. There may be some initial (temporary) pain at the injection site. [medicalnewstoday.com]

Therefore, to prevent these and other complications, prompt and appropriate treatment of OMD is important. [doi.org]
