Paroxysmal kinesigenic dyskinesia (PKD), also called paroxysmal kinesigenic choreoathetosis (PKC), is a rare hyperkinetic movement disorder of the paroxysmal dyskinesias characterized by attacks of involuntary movements, which are triggered by sudden voluntary movements.
Huntington's disease (HD), also known as Huntington's chorea, is an incurable neurodegenerative disease [7] that is mostly inherited. [8] The earliest symptoms are often subtle problems with mood or mental/psychiatric abilities. [9] [1] A general lack of coordination and an unsteady gait often follow. [2]
Paroxysmal dyskinesia is a rare disorder, however the number of individuals it affects remains unclear. There are three different subtypes of PD that include paroxysmal kinesigenic dyskinesia (PKD), paroxysmal nonkinesigenic dyskinesia (PNKD), and paroxysmal exercise-induced dystonia (PED).
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.
Hyperkinetic movement disorders refer to dyskinesia, or excessive, often repetitive, involuntary movements that intrude upon the normal flow of motor activity. Hypokinetic movement disorders fall into one of four subcategories: akinesia (lack of movement), hypokinesia (reduced amplitude of movements), bradykinesia (slow movement), and rigidity ...
Sydenham's chorea occurs as a complication of streptococcal infection. Twenty percent (20%) of children and adolescents with rheumatic fever develop Sydenham's chorea as a complication. It is increasingly rare, which may be partially due to penicillin, improved social conditions, and/or a natural reduction in the bacteria (Streptococcus) it has ...
Benign Hereditary Chorea is characterized by early onset of an abnormal gait, speech articulation difficulties, anxiety, and chorea. [5] The clinical spectrum of symptoms resulting from BHC is vast, manifesting as thyroid agenesis to dysarthria to distress syndrome. As a result, genetic testing is the only way to confirm the syndrome.
Late-onset dyskinesia, also known as tardive dyskinesia, occurs after long-term treatment with an antipsychotic drug such as haloperidol (Haldol) or amoxapine (Asendin). The symptoms include tremors and writhing movements of the body and limbs, and abnormal movements in the face, mouth, and tongue – including involuntary lip smacking, repetitive pouting of the lips, and tongue protrusions.
