Myoclonic dystonia or Myoclonus dystonia syndrome is a rare movement disorder that induces spontaneous muscle contraction causing abnormal posture. The prevalence of myoclonus dystonia has not been reported, however, this disorder falls under the umbrella of movement disorders which affect thousands worldwide. [1]
Progressive myoclonus epilepsy (PME) is a group of diseases characterized by myoclonus, epileptic seizures, tonic–clonic seizures, and other serious symptoms such as trouble walking or speaking. These rare disorders often get worse over time and can be fatal.
Dystonia is often intensified or exacerbated by physical activity, and symptoms may progress into adjacent muscles. [4] The disorder may be hereditary or caused by other factors such as birth-related or other physical trauma, infection, poisoning (e.g., lead poisoning) or reaction to pharmaceutical drugs, particularly neuroleptics, [3] or stress.
Movement disorders including tremors, dystonia (spasms), myoclonus (jerky movements) Visual symptoms including loss of vision or double vision; Speech symptoms including dysphonia (whispering speech), slurred or stuttering speech; Sensory disturbance including hemisensory syndrome (altered sensation down one side of the body)
Juvenile-onset DRPLA presents with ataxia and symptoms consistent with progressive myoclonus epilepsy [16] (myoclonus, multiple seizure types and dementia). Other symptoms that have been described include cervical dystonia, [17] corneal endothelial degeneration [18] autism, and surgery-resistant obstructive sleep apnea. [19]
Other symptoms Movement disorders (chorea and/or dystonia) Cortical visual impairment Impaired muscle tone (either hypotonia or, more rarely, spasticity) Cortical visual impairment Oculogyric crisis Scoliosis Speech disorders (e.g., aphasia, agnosia, speech dyspraxia) Autism spectrum disorder Movement disorders (chorea and/or dystonia)
Palatal myoclonus is a rare condition in which there are rhythmic jerky movements or a rapid spasm of the palatal (roof of the mouth) muscles. Chronic clonus is often due to lesions of the central tegmental tract (which connects the red nucleus to the ipsilateral inferior olivary nucleus ).
Symptoms of this disorder vary among the people who have it. In every patient, these symptoms start between the late-childhood or early adolescence of the people with the disorder [2] (hence juvenile-onset). [3] In most people with this disorder, the cause is unknown. It is a type of dystonia.
