[Risk factors for tardive movement disorders in schizophrenia]
Tijdschrift Voor Psychiatrie
|February 12, 2015
Summary
Identifying risk factors for tardive dyskinesia in schizophrenia is key for prevention. Non-Caucasian race and older age are significant predictors, guiding medication choices and early detection strategies.
Area of Science:
- Psychiatry
- Neuroscience
- Pharmacology
Background:
- Tardive movement disorders, particularly tardive dyskinesia, are prevalent in schizophrenia patients.
- Understanding risk factors is crucial for developing effective preventive strategies.
Purpose of the Study:
- To classify movement disorders in schizophrenia.
- To identify associated risk factors.
- To inform preventive strategies for movement disorders.
Main Methods:
- Systematic literature search of PubMed for prospective studies.
- Inclusion of studies with homogeneous schizophrenia populations and defined movement disorders.
- Selection of studies with repeatedly identified risk factors.
Main Results:
- Tardive dyskinesia is well-documented.
- Key risk factors include antipsychotic use (especially first-generation), non-Caucasian race, early extrapyramidal symptoms, and older age.
- Limited conclusive genetic evidence for tardive movement disorders exists.
Conclusions:
- Non-Caucasian race and older age are readily identifiable risk factors for tardive dyskinesia prevention.
- Medication selection should consider low D2 affinity drugs.
- Regular monitoring for early signs of tardive dyskinesia is advised, with low D2 affinity agents or clozapine as treatment options if it occurs.

01:29Psychological and Sociocultural Causes of Schizophrenia

Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

01:21Antipsychotic Drugs: Therapeutic Uses and Side Effects
1.2K
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...

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...

The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic...
