Hypokinetic movement disorders fall into one of four subcategories: akinesia (lack of movement), hypokinesia (reduced amplitude of movements), bradykinesia (slow movement), and rigidity. In primary movement disorders, the abnormal movement is the primary manifestation of the disorder.
Since it is difficult to measure extrapyramidal symptoms, rating scales are commonly used to assess the severity of movement disorders. The Simpson-Angus Scale (SAS), Barnes Akathisia Rating Scale (BARS), Abnormal Involuntary Movement Scale (AIMS), and Extrapyramidal Symptom Rating Scale (ESRS) are rating scales frequently used for such assessment and are not weighted for diagnostic purposes ...
As there appeared to be a connection with PED and mutated GLUT1 transporters a possible treatment was looking at changing patients diets. A common treatment for another disorder (GLUT1 Deficiency Syndrome) with a mutated GLUT1 transporter is the ketogenic diet. The diet is a strict 3:1 ratio of fat (3) to protein and carbohydrates (1).
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 ...
Pseudoathetosis is a movement disorder, very similar to athetosis, in which the symptoms are not differentiable from those of actual athetosis, however the underlying cause is different. While actual athetosis is caused by damage to the brain, specifically in the basal ganglia, [ 4 ] pseudoathetosis is caused by the loss of proprioception. [ 17 ]
Motor disorders are malfunctions of the nervous system that cause involuntary or uncontrollable movements or actions of the body. [3] These disorders can cause lack of intended movement or an excess of involuntary movement. [4] Symptoms of motor disorders include tremors, jerks, twitches, spasms, contractions, or gait problems.

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.
Tardive tourettism is a tic disorder featuring the same symptoms as Tourette syndrome. The two disorders are extremely close in nature and often can only be differentiated by the details of their respective onsets. Tardive myoclonus, a rare disorder, presents as brief jerks of muscles in the face, neck, trunk, and extremities. [13]
