For the majority of patients, myoclonus is relatively more severe than dystonia and can lead to significant functional disability. [uthsc.pure.elsevier.com]
Indeed, the biphasic active motor threshold correlated with the self-rated but not the neurologist-rated global disability score. [ahcmedia.com]
The patients in our cohort experienced significantly more functional disabilities compared to healthy controls and a significant relation was found between the severity of the movement disorder and psychical disabilities. [ojrd.biomedcentral.com]

Musculoskeletal
- Torticollis
The head may tilt (laterocollis) or twist to one side (rotational torticollis), forward (anterocollis) or backward (retrocollis). The movements may be sustained or jerky (myoclonic torticollis). [netdoctor.co.uk]
Spasmodic torticollis Torticollis is a twisting of the head and neck caused by a shortened sternocleidomastoid muscle, tipping the head toward the shortened muscle, while rotating the chin in the opposite direction. [patient.info]

Myoclonus-dystonia is a movement disorder that typically affects the neck, torso, and arms. Individuals with this condition experience quick, involuntary muscle jerks or twitches (myoclonus). [ghr.nlm.nih.gov]
Overall, Deep brain stimulation shows promise as a viable treatment for myoclonus dystonia. [17] Although myoclonus and dystonia are present in myoclonus dystonia patients, optimum treatment for myoclonus dystonia differs from the treatment for myoclonus [en.wikipedia.org]

Treatment
Management of M-D Treatment of physical symptoms The need for treatment depends on the severity of the symptoms – some people find they can cope without treatment. [dystonia.org.uk]
Myoclonus-Dystonia Syndrome can’t be cured, and the current therapy is mainly aimed to improve the symptoms, which includes medical and surgical treatment. All in all, MDS remains poorly responsive to medical treatment. [omicsonline.org]

Etiology
This region contains an excellent candidate gene for involvement in the etiology of MD, the D2 dopamine receptor ( DRD2 ) gene. [pnas.org]
Etiology The only known causative gene of MDS is the epsilon-sarcoglycan ( SGCE ) gene (7q21.3), encoding a transmembrane protein that is part of the dystrophin-associated glycoprotein complex found in skeletal and cardiac muscle. [orpha.net]
Movement disorders in children are uncommon and thus are challenged by limited experience of pediatric care providers in the accurate diagnosis of etiology, correct characterization of the clinical phenotype, knowledge of pharmacologic interventions, [journals.lww.com]

Pathophysiology
The authors concluded that cerebellar dysfunction plays a role in pathophysiology of dystonia and that their findings support parasagittal cerebellum involvement in pathogenesis of myoclonus-dystonia, which the authors believe to be different from other [ahcmedia.com]
But recognizing the phenomenology and understanding the pathophysiology are essential to ensure appropriate treatment. Hyperkinetic Movement Disorders provides a clinical pathway for effective diagnosis and management of these disorders. [books.google.com]

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]
In very extreme cases, sufferers are unable to prevent their eyes from clamping shut so that despite normal vision they are functionally blind. [netdoctor.co.uk]
This medication is directly injected into the muscles causing the involuntary jerks at relatively low doses, allowing for relaxation of the muscles, thus preventing the spasms. [bcm.edu]
This study can be regarded as a pilot study due to the relatively small number of patients in each study group ultimately preventing further and more elaborate statistic analysis of the available results. [frontiersin.org]
