What is drug induced acute dystonia?
Acute dystonia, sometimes called an acute dystonic reaction, can occur within hours or days of exposure to a dopamine blocking drug or, less commonly, after an increased dose of a dopamine blocking drug or decreased dose of a concurrent anticholinergic drug (e.g. benztropine).
What causes acute dystonia?
The etiology of acute dystonic reaction is thought to be due to dopaminergic-cholinergic imbalance in the basal ganglia. Reactions usually occur shortly after the initiation of an offending agent or an increased dose of a possible offending agent.

Stimulant drugs (e.g., amphetamine, methylphenidate, and pemoline) have been known to produce a variety of movement disorders such as dyskinesias, dystonia, stereotypic behavior, and tics.
Can opiates cause dystonia?
[6] Hence, during an opioid abstinent state, opioid receptors will not be activated, resulting in a lack of inhibition of the inhibitory GABAergic interneurons in the VTA, ultimately leading to decreased dopamine neurotransmission to the NA, creating a dopamine depletion state, which in turn causes dystonia.
Does drug induced dystonia go away?
The potential cause of drug induced dystonia is the development of dopamine receptor hypersensitivity after prolonged blockade of these receptors with the use of antipsychotics or anti emetics. In almost all instances, drug induced dystonias are reversible, resolving after the discontinuation of the offending drug.
Is acute dystonia permanent?
There's no cure for dystonia, but medications and therapy can improve symptoms. Surgery is sometimes used to disable or regulate nerves or certain brain regions in people with severe dystonia.

Other causes. Temporal epilepsy may cause bizarre behaviour and bizarre movements and can therefore be confused with dystonia. 2 Hypocalcaemia may cause features resembling those of acute dystonia. If treatment for acute dystonia is not successful, serum calcium concentrations should be measured. 2.
How to diagnose drug induced dystonia?
Drug-induced dystonia is diagnosed by the combination of history of exposure to a likely causative medication, plus rapid response to anticholinergic medication. Initial blood work can identify low magnesium or calcium, which can be repleted intravenously. History of a wound and no recent tetanus booster may suggest tetanus. There is no specific diagnostic test for tetanus: it is a clinical diagnosis. Chronicity of symptoms without exposure to causative medication should suggest exploration for other neurologic symptoms, such as tremor or rigidity of Parkinson’s disease. Symptoms since childhood or adolescence may prompt genetic investigation for primary dystonias. EEG can help diagnose partial seizures.
What is dystonia in physiology?
Dystonia is a form of hyperkinetic movement disorder. It is a syndrome of involuntary sustained muscle contractions with frequent repetitive and twisting movements, and/or abnormal postures. Characteristic movements include trismus, mouth opening, grimacing, blepharospasm, glossopharyngeal contraction, stridor, oculogyric crisis, opisthotonos, torticollis, and retrocollis.

Should antipsychotics be discontinued?
The offending drug agent should be discontinued when possible. If the offending drug has a long half-life, anticholinergic doses to relieve spasms may need to be repeated. In patients who need to continue an antipsychotic drug, prophylaxis can be considered by adding an anticholinergic like benztropine.
