  • The Biological Approach.
    • The model itself assumes that mental disorders have physiological causes related to he physical structure and/or functioning of the brain.
    • It also perceives abnormalities as physical illnesses caused by biological processes, specifically in the structure and workings of the brain.
    • BING
      • Biochemistry
        • Biochemistry can affect the level of neurotransmitters and hormones. For instance, elevated levels  of the neurotransmitter dopamine have been associated with Schizophrenia.
          • Janowsky 2009 reported a link between abnormal neurotransmitter levels and the development of depression and manic depression
      • Infection
        • Baterical infections and virusues can change the brain and cause malfunctions.
          • Brown et al looked at syphilis. In the latter stages of the illness, tumour like masses develop in the brain. Memory, intellect and moods are effected.
      • Neurology
        • Abnormality can occur if the brain is damaged in some way. This can happen if an individual is born with brain damage, or develops it in later life as a result of illness or trauma.
          • Tien et al reported that drug abuse through heavy and persistent use of cocaine can lead to brain damage resulting in psychosis.
      • Genes
        • Genetics are linked with increased risks of schizophrenia. A child would have a 1% chance of having schizophrenia but having a parent with it would raise that figure to 10%.
          • Weinberger looked at chromosome 22 and the gene. He found 1 gene associated with that had doubled a risk of schizophrenia.
    • Evaluation  points.
      • Doesn't blame the sufferer because mental illness is seen the same as physical illness.
      • Labelling someone with a disorder will mean they have to carry that stigma throughout their entire life.
      • Takes control away from the sufferer; only a doctor can fix the.
      • Lots of research.
      • Reductionist as it reduces the complex human behaviour to just cells and genes, not psychological factors or social factors.
  • Infection
    • Baterical infections and virusues can change the brain and cause malfunctions.
      • Brown et al looked at syphilis. In the latter stages of the illness, tumour like masses develop in the brain. Memory, intellect and moods are effected.
