What is drug induced chorea?
Drug induced chorea may be an acute phenomenon or the consequence of long term therapy. Multiple drugs including dopamine agonists, levodopa therapy, oral contraceptives, and anticonvulsants have been implicated in the acute chorea (box 4).
What are movement disorders?
The term movement disorders refers to a group of nervous system (neurological) conditions that cause either increased movements or reduced or slow movements. These movements may be voluntary or involuntary. Common types of movement disorders include: Ataxia.
What are chorea movements?
Definition. Chorea is an abnormal involuntary movement disorder, one of a group of neurological disorders called dyskinesias, which are caused by overactivity of the neurotransmitter dopamine in the areas of the brain that control movement.
What are types of movement disorders?
Common types of movement disorders include:
- Ataxia. This movement disorder affects the part of the brain that controls coordinated movement.
- Cervical dystonia.
- Chorea.
- Dystonia.
- Functional movement disorder.
- Huntington’s disease.
- Multiple system atrophy.
- Myoclonus.
How do drug induced and parkinsonism differ?
There are key differences to note between parkinsonism from PD and parkinsonism as a side effect of medication. Drug-induced parkinsonism often affects both sides of the body equally, whereas PD is virtually always asymmetric, affecting one side of the body more than the other.
What are the symptoms of drug-induced Parkinsonism?
Drug-induced Parkinsonism (DIP) is the second most prevalent cause of secondary Parkinsonism. Its symptoms, which include tremor, rigidity, bradykinesia, and gait disturbance, are very similar to those of Parkinson’s disease (PD).
What causes drug-induced Parkinsonism?
Drug-induced parkinsonism is caused by medications that reduce dopamine levels in the brain. Dopamine is a neurotransmitter that works to control bodily movements. Dopamine is also part of the brain’s reward system. It helps you feel pleasure and enjoyment, and it supports your ability to learn and focus.
