Drug-induced tremor, clinical features, diagnostic approach and management

Parkinsonism refers to a cluster of symptoms that mimic the movement problems caused by Parkinson’s disease. It’s sometimes referred to as atypical Parkinson’s disease, secondary parkinsonism, or Parkinson’s plus. In some cases, extrapyramidal symptoms may not affect you too much. They can negatively affect quality of life and contribute to frustration and distress.

Medication-induced tremors: background and pathophysiology

You may also decide that the side effects are worth it if the medication effectively treats your condition. If you begin to experience any side effects while taking an antipsychotic, talk to your doctor as soon as possible. In some cases, they can be permanent, but treatment often leads to improvement. If you have side effects, you may decide to stop taking your medication to make them go away, but this can be dangerous. If you stop taking your medication, you could experience more serious symptoms. It’s important to keep taking your medication as prescribed until you talk to your doctor.

In some cases, it is not possible to reduce the dose of the offending agent and additional medication (e.g., propranolol) may be necessary to try and treat the tremor. In rare instances where clinically appropriate, deep brain stimulation surgery may be necessary to ameliorate the tremor. Tremors can occur in the setting of withdrawal states, especially with benzodiazepines, ethanol, and opiates.

Antipsychotics help improve symptoms by binding to dopamine receptors in your central nervous system and blocking dopamine. This may prevent the basal ganglia from getting enough dopamine. Finally, it will be important to further define the most vital anatomical structures for the generation of tremor in the CNS and further what is a good sobriety gift understand the physiology of these interconnected players. It will also be important to develop further knowledge of neurotransmitters and their receptors that may influence tremor or actually suppress it.

Preventing Drug-Induced Tremors

Parkinsonism-hyperpyrexia disorder, also known as akinetic crisis, is a rare but potentially fatal complication of Parkinson’s disease. It can also be precipitated by an infection or other metabolic disturbance. The clinical features overlap with neuroleptic malignant syndrome.

1. Drug-induced tremors can occur when you move your body a certain way or are in certain positions.
2. It’s sometimes referred to as atypical Parkinson’s disease, secondary parkinsonism, or Parkinson’s plus.
3. They often show up a few hours after your first dose but can show up anytime within the first few weeks.
4. If you stop taking your medication, you could experience more serious symptoms.
5. Anticholinergic drugs to prevent, or reduce the severity of, drug-induced movement disorders have been suggested, however there is no evidence to support this.

Serotonin syndrome

They can be classified chronologically based on the time of onset after drug ingestion, as why do alcoholics get red noses acute, subacute or tardive. The basic classification is resting, action and intention tremor. Differentiation can often be made according to the time of onset, relation with starting or increasing the dosage of the medication and the course. Rest tremor is often related to antipsychotics and antiemetics and action tremor to lithium, antidepressants, valproic acid, and other anticonvulsants, but also to many drugs used in somatic conditions. The development of intention tremor should alarm the doctor because it could be an intoxication.

Illicit drugs

For example, serotonin syndrome tends to occur more acutely than neuroleptic malignant syndrome. There is rigidity in neuroleptic malignant syndrome whereas myoclonus, hyperreflexia with clonus, and mydriasis are more common in serotonin syndrome. Management consists of altering the dose of, or if possible stopping, the offending drug, or switching to an alternative drug.

It may take anywhere from 4 to 18 months before your symptoms subside. Serotonin-norepinephrine reuptake inhibitors (SNRIs), another form of antidepressant, may also have this effect. SNRIs are used to treat major depressive disorders, ADHD, fibromyalgia, and other conditions. Serotonin reuptake inhibitors (SSRIs) are widely used as antidepressants and mood stabilizers.

When Parkinson’s disease symptoms are caused by medications, they’re referred to as drug-induced parkinsonism. Parkinsonism caused by antipsychotic (neuroleptic) medication is sometimes referred to as neuroleptic-induced parkinsonism. It usually begins within 48 hours after you start taking an antipsychotic but often improves with treatment. Dystonic reactions may also be treated with antihistamines and drugs that treat symptoms of Parkinson’s disease. While the movement disorder usually occurs following drug ingestion, it can also occur during the withdrawal phase. Typically, it subsides on cessation yellow eyes after drinking of the drug, but can last for months.
