However, the two phenomena are not the same since the former, namely antipsychotic-induced akathisia, suggests a known neuroreceptor mechanism (e.g., dopamine-receptor blockade). [11] Diagnosis is based on the symptoms. [2] It differs from restless leg syndrome in that akathisia is not associated with sleeping. However, despite a lack of ...
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.
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.
Motor disorders are disorders of the nervous system that cause abnormal and involuntary movements. They can result from damage to the motor system. [1]Motor disorders are defined in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) – published in 2013 to replace the fourth text revision – as a new sub-category of neurodevelopmental disorders.
Chorea, or (rarely) choreia, (/ k ə ˈ r i ə /) is an abnormal involuntary movement disorder, characterized by quick movements of the hands or feet. It is one of a group of neurological disorders called dyskinesias. The term chorea is derived from Ancient Greek χορεία 'dance', as the movements of the body is comparable to dancing.
Involuntary movements can take many forms such as ballism, chorea or dystonia and usually only affect one side of the body or one limb in particular. There are two types of PKD, primary and secondary. Primary PKD can be further broken down into familial and sporadic.
The exact prevalence of the disorder is not known; several family and population studies show that as many as 25% of cervical dystonia patients have relatives that are undiagnosed. [29] [30] Studies have shown that spasmodic torticollis is not diagnosed immediately; many patients are diagnosed well after a year of seeking medical attention. [1]
Athetosis is a symptom primarily caused by the marbling, or degeneration of the basal ganglia. [citation needed] This degeneration is most commonly caused by complications at birth or by Huntington's disease, in addition to rare cases in which the damage may also arise later in life due to stroke or trauma.
