Drug-induced and tardive movement disorders
1Graduate Hospital Parkinson's Disease and Movement Disorder Center, Philadelphia, Pennsylvania 19146.
Summary
Drug-induced movement disorders, often caused by neuroleptics, manifest as abnormal body movements. Managing these complex conditions is challenging, with a frequently poor prognosis due to reliance on the causative medication.
Area of Science:
- Neurology
- Pharmacology
Background:
- Drug-induced and tardive movement disorders are common extrapyramidal conditions encountered in neurological practice.
- These iatrogenic disorders are frequently caused by neuroleptic medications.
Purpose of the Study:
- To review the characteristics and management of drug-induced and tardive movement disorders.
- To highlight the complexity and often poor prognosis associated with these conditions.
Main Methods:
- Review of literature on drug-induced and tardive movement disorders.
- Analysis of common clinical presentations and management strategies.
Main Results:
- Movement disorders include tremor, chorea, athetosis, dyskinesias, dystonia, myoclonus, tics, ballismus, and akathisia.
- Parkinsonism, dyskinesias, and dystonia are the most prevalent types.
- Management is complex, often complicated by the patient's need for the offending drug.
Conclusions:
- Cautious use of neuroleptics and other causative drugs is essential.
- Thorough risk-benefit assessment is critical before initiating therapy with drugs known to cause movement disorders.

01:21Antipsychotic Drugs: Therapeutic Uses and Side Effects
Antipsychotic drugs primarily block dopamine and serotonin receptors and cholinergic, adrenergic, and histaminergic receptors, thereby reducing hallucinations and delusions in conditions like schizophrenia. However, they can trigger unwanted extrapyramidal effects such as dystonias, Parkinson-like symptoms, and tardive dyskinesia.
Despite these side effects, antipsychotics are used therapeutically for various purposes, including managing schizophrenia, preventing nausea and vomiting, curbing...

01:15Parkinson's Disease: Overview
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is to...
01:24Parkinson's Disease: Treatment
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.

01:28Drugs Affecting GI Tract Motility: Dopamine Receptor Antagonists
Prokinetic agents are specialized medications that stimulate gastrointestinal (GI) motility, promoting food movement through the GI tract. Dopamine, an inhibitory neurotransmitter, plays a significant role in this process, reducing GI motility and indirectly controlling the speed of digestion. Dopamine receptor antagonists, such as metoclopramide and domperidone, offer a unique advantage as prokinetic agents. By blocking the dopamine receptors, these drugs increase GI motility, improving food...
01:30Positive Symptoms of Schizophrenia: Hallucinations and Delusions
Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.
Thought Disorders
Disorganized and unusual thought processes mark thought disorders in schizophrenia. One key feature is disorganized speech, where an individual's conversation includes loosely...

01:24Parkinson Disease l: Introduction
Parkinson’s disease is a chronic, progressive neurodegenerative disorder that primarily affects movement. It is characterized by motor symptoms such as resting tremors, muscle rigidity, bradykinesia (slowness of movement), and postural instability. Patients may notice hand tremors at rest, stiffness during movement, or a shuffling gait. In addition to motor features, non-motor symptoms include sleep disturbances, mood and behavioral changes, constipation, and cognitive impairment, all of which...
