  • Biological Abnormality
    • Infection
      • Viruses/bacteria
        • Sz's - Flu when pregnant can pass sz to unborn child
          • An - Glandular fever can disrupt DNA in hyptohalumus
      • After flue epidemic in late 50's, sz rose in population 30 years later
    • Neuroanatomy
      • Sz's = Large ventricles Depression = Less grey matters
      • Scans are objective, can see differences, therefore very scientific and valid
    • Genetics
      • Abnormality is inherited, the more genes we share the greater risk of abnormality
      • But MZ twins have identical DNA  and concordance rate is not 100% so must be other factrs
      • Twins share environment so this could be an infleunce
    • Biochemistry
      • Sz's = High dopamine  An's = high serotonin Bul = low serotonin
      • Drugs work therefore because they work with biochemistry is must be the cause!
  • Abnormality is caused by physical factors

  • Environmental insults
    • Sz = Cannabis
  • Biological theories neglect other influences such as the environment ... Reductionist
    • Biological Reductionist - Neglects a higher order of thinking, treatments do not empower the patient
