What are the biological explanations for schizophrenia?
Research suggests schizophrenia may be caused by a change in the level of 2 neurotransmitters: dopamine and serotonin. Some studies indicate an imbalance between the 2 may be the basis of the problem. Others have found a change in the body’s sensitivity to the neurotransmitters is part of the cause of schizophrenia.
Is the biological explanation for schizophrenia reductionist?
A final weakness of the genetic explanation of schizophrenia is that it is biologically reductionist.
How does the biological approach treat schizophrenia?
Biological treatments of schizophrenia primarily consist of neuroleptics. These drugs can be prescribed in a relatively standardized manner (chlorpromazine equivalent), but neuroleptics will be less than effective on the type of schizophrenia with negative symptoms.
What is the biochemical explanation for mental illness?
Biochemistry – the dopamine hypothesis argues that elevated levels of dopamine are related to symptoms of schizophrenia. Neuroanatomy – differences in brain structure (abnormalities in the frontal and pre-frontal cortex, enlarged ventricles) have been identified in people with schizophrenia.
Is schizophrenia a biological disorder?
Data from modern scientific research proves that schizophrenia is unequivocally a biological disease of the brain, just like Alzheimer’s Disease and Bipolar Disorder. For one thing, schizophrenia is now known to be partially caused by genetics and to be inherited.
What is AO2 AQA Psychology?
AO2: Apply knowledge and understanding of psychological ideas, processes and procedures. AO3: Analyse and evaluate psychological information, ideas, processes and procedures to make judgements and draw conclusions.
What biological and psychosocial treatments for schizophrenia are available?
Four psychosocial treatment approaches have received substantial empirical support and warrant further study:
- Social skills training.
- Family psychoeducation.
- Cognitive therapy.
- Cognitive rehabilitation.
How does biological psychology explain behavior?
The biological approach believes that most behavior is inherited and has an adaptive (or evolutionary) function. Biological psychologists explain behaviors in neurological terms, i.e., the physiology and structure of the brain and how this influences behavior.
What is a biological illness?
Viruses. Biological Disorders: disturbances of the normal state of the body or mind. Disorders of structure or function in an animal or plant. ( Oxford) Disorders may be caused by genetic factors, disease, or “trauma.” (
How do biological theorists explain abnormal behavior?
Biological Influences The medical or biological perspective holds the belief that most or all abnormal behavior can be attributed to genetic and environmental influences on physical functioning.
Is schizophrenia biological or environmental?
Schizophrenia is thought to be the result of a culmination of biological and environmental factors. While there is no known cause of schizophrenia, there are genetic, psychological, and social factors thought to play a role in the development of this chronic disorder.
What is biological factor?
n. Anything which affects the function and behavior of a living organism. Internally, this factor can be a physical, physiological, chemical, neurological, or genetic condition which causes a psychological effect. Biological factors are seen as the primary determinants of human behavior. See biological determinism.
Is there a biological explanation of schizophrenia?
Outline and Evaluate Two or More Biological Explanations of Schizophrenia. There are two main biological theories which explain the assumed causes of schizophrenia: Genetic and Dopamine Hypothesis.
Is schizophrenia caused by abnormal neurotransmitter activity?
Biochemical factors are used to suggest that schizophrenia is caused by abnormal neurotransmitter activity. The main aspect of this explanation is the Dopamine hypothesis. Schizophrenia has been linked to with high levels of dopamine in the brain. Dopamine is a neurotransmitter associated with attention.
What is the dopamine hypothesis of schizophrenia?
The dopamine hypothesis is another biological explanation for schizophrenia. The original version suggested it was due to high levels or activity of dopamine in the subcortex (hyperdopaminergia).
What is the best approach to explain schizophrenia?
In order to explain schizophrenia effectively it would be better to take an interactionist approach, such as the diathesis stress model. This suggests that biological factors predispose someone to schizophrenia, but this has to be ‘triggered’ by some sort of experience or stressor.
