    Study Notes

    Understanding Psychological Disorders

    • Disorders can be approached from different perspectives: biological, psychological, and sociocultural.
    • The biological approach views disorders as resulting from abnormal genes or neurobiological dysfunction.
    • Psychological approaches focus on cognition and emotional regulation, often considering these along a continuum.

    Models of Understanding

    • The diathesis-stress model highlights that disorders emerge when a risk factor and a trigger or stress converge in an individual.
    • A biopsychosocial approach acknowledges the influence of biological, psychological, and sociocultural factors in understanding disorders.
    • Continuum models in biological perspectives suggest disorders exist on a spectrum rather than as binary states.

    Brain Structure

    • The brain consists of three main regions: hindbrain, midbrain, and forebrain.
    • Key structures within the midbrain include the superior colliculus, inferior colliculus, and substantia nigra.
    • The thalamus serves as a sensory relay station to the cerebrum, while the hindbrain is crucial for basic life functions including coordination of movement.

    Neurotransmitters and Hormones

    • Neurotransmitters and hormones are vital biochemical messengers affecting behavior and emotional states.
    • GABA functions as an inhibitory neurotransmitter, working to regulate the activity of other neurotransmitters.
    • Dopamine is linked to reward responses and is significant in disorders such as Parkinson's disease; serotonin impacts mood and emotional well-being.

    Genetic Influences on Behavior

    • Behavioral genetics analyzes the inheritance of behavioral tendencies and how genes affect behavior.
    • Chromosomes, which contain genes, can determine inherited characteristics and when altered, can lead to major defects.
    • Polygenic effects refer to the influence of multiple genes on psychological traits or disorders.

    Drug Treatments for Psychological Disorders

    • Antipsychotic drugs, including phenothiazines, reduce symptoms of psychosis but can lead to side effects like tardive dyskinesia.
    • Antidepressants target symptoms of depression, with SSRIs and SNRIs being common choices; side effects include nausea and sexual dysfunction.
    • Lithium is primarily used as a mood stabilizer, especially in manic episodes, while anticonvulsants can also effectively treat mania with fewer side effects.

    Advanced Treatment Procedures

    • Electroconvulsive therapy is effective for severe depression; newer treatments like repetitive transcranial magnetic stimulation focus high-intensity pulses on brain structures.
    • Vagus nerve stimulation involves attaching electrodes to the vagus nerve, while deep brain stimulation surgically implants electrodes in specific brain regions.
    • Psychosurgery, once common for various mental disorders, is now more precise thanks to advances in surgical and neurological techniques.

    Risks and Side Effects of Treatments

    • Barbiturates carry risks including withdrawal delirium and addiction; benzodiazepines also pose significant addiction and withdrawal concerns.
    • Often, drug treatments must balance therapeutic benefits with potential side effects, underscoring the complexity of managing psychological disorders.
