Antipsychotic Drugs: Therapeutic Uses and Side Effects01:21

Antipsychotic 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...

Antipsychotic Drugs: Typical and Atypical Agents

Antipsychotic drugs are classified into first-generation (typical) drugs including phenothiazines; and second-generation (atypical) drugs. Chlorpromazine hydrochloride (Thorazine), a phenothiazine derivative, broadly impacts the central, autonomic, and endocrine systems. This drug, along with typical agents like haloperidol (Haldol), primarily works by antagonizing D2 receptors, thus reducing dopaminergic neurotransmission. However, typical antipsychotics can cause side effects such as sedation...

Area of Science:

  • Neuroscience
  • Movement Disorders
  • Psychiatry

Background:

  • Extrapyramidal signs are characterized by altered motor tone, movement velocity, and involuntary movements.
  • These signs are broadly categorized into hypokinetic (e.g., Parkinson's disease) and hyperkinetic (e.g., Huntington's disease) types.
  • Extrapyramidal signs are relevant in major psychiatric disorders and various neurological conditions.

Purpose of the Study:

  • To explore the neuroscience underlying extrapyramidal disorders.
  • To discuss the significance of extrapyramidal signs in major psychiatric disorders.
  • To outline the primary extrapyramidal movement disorders and methods for eliciting their signs.

Main Methods:

  • Review of neuroscience principles related to motor control.
  • Analysis of the clinical relevance of extrapyramidal signs in psychiatric conditions.
  • Description of major extrapyramidal movement disorders and diagnostic elicitation techniques.

Main Results:

  • Provides insights into the neurobiological basis of extrapyramidal signs.
  • Highlights the connection between extrapyramidal signs and psychiatric diagnoses.
  • Details specific movement disorders and practical methods for clinical assessment.

Conclusions:

  • Extrapyramidal signs are key indicators in diagnosing and understanding a range of neurological and psychiatric conditions.
  • A comprehensive understanding of their neuroscience and clinical presentation is essential for effective patient management.
  • This review serves as a guide to identifying and interpreting these critical motor signs.
