Dyskinesia can be anything from a slight tremor of the hands to an uncontrollable movement of the upper body or lower extremities. Discoordination can also occur internally especially with the respiratory muscles and it often goes unrecognized. [3] Dyskinesia is a symptom of several medical disorders that are distinguished by their underlying ...
Movement disorders are clinical syndromes with either an excess of movement or a paucity of voluntary and involuntary movements, unrelated to weakness or spasticity. [1] Movement disorders present with extrapyramidal symptoms and are caused by basal ganglia disease . [ 2 ]
Studies on diseases that are similar in nature to PD have revealed insights into the causes of movement disorders. Hypnogenic paroxysmal dyskinesia is a form of epilepsy affecting the frontal lobe . Single genes have been identified on chromosomes 15, 20, and 21, which contribute to the pathology of these epilepsy disorders. [ 4 ]
A movement disorder similar to PKD was first mentioned in research literature in 1940 by Mount and Reback. They described a disorder consisting of attacks of involuntary movements but unlike PKD, the attacks lasted minutes to hours and were found to be caused by alcohol or caffeine intake. [15] They named it paroxysmal dystonic choreoathetosis.
It is also associated with mental health disorders and prolonged inactivity due to illness, amongst other diseases. The other category of movement disorder is hyperkinesia that features an exaggeration of unwanted movement, such as twitching or writhing in Huntington's disease or Tourette syndrome. [2]
Paroxysmal nonkinesigenic dyskinesia (PNKD) is an episodic movement disorder first described by Mount and Reback in 1940 under the name "Familial paroxysmal choreoathetosis". [2] It is a rare hereditary disease that affects various muscular and nervous systems in the body, passing to roughly fifty percent of the offspring.
Sometimes a lumbar puncture is performed to measure concentrations of biopterin and neopterin, which can help determine the exact form of dopamine-responsive movement disorder: early onset parkinsonism (reduced biopterin and normal neopterin), GTP cyclohydrolase I deficiency (both decreased) and tyrosine hydroxylase deficiency (both normal).
PED differs from two closely related disorders, for example paroxysmal kinesogenic dyskinesia (PKD) and paroxysmal nonkinesigenic dyskinesia (PNKD), based on what brings on the symptoms, namely prolonged exercise, such as brisk walking or running for at least 10 minutes. This is in contrast to PKD where the symptoms are brought about by sudden ...
