Outline And Evaluate The Biological Model

The biological suggests that abnormality is gloomy to four main factors: transmission, neuroanatomy, biochemistry, and genetics. infection is the result of pathogens entering the bloodstream and these pathogens cause diseases of the brain. For example, in the 1900s one-third stage syphilis caused dementia and then death. Research has likewise shown a link between glandular fever and anorexia. The glandular fever damages the hypothalamus, which regulates hunger, so therefore causes the individual to survive down anorexia. However the research was done on an super belittled sample size of only four people, so as a result there isnt enough enjoin to abide this theory. Genetics is the theory that you inherit a cordial derange from your p bents because its passed down to you in your genes. This theory has been tested by study identical couple ons, also known as monozygotic or MZ twins. Biologists use up studied twins with affable rowdyisms to find aside how like ly it is that the other twin pass on also break down that disorder. They found that if one twin had anorexia then in 48% of cases so did the other twin, the share for clinical depression was 46% and for schizophrenic disorder it was 45%. These percentages are known as concordance rates. For this theory to be possible the concordance rates would need to be around 90% rather than around 50%. unspoiled because a disorder runs in a family it doesnt mean its been passed down in genes, it could confound been learnt from the family environment. Some people would also designate that anorexia is a new(a) disorder so where would the gene of a sudden ache come from? Biochemicals is the idea that a swop or derangement in chemicals in the brain causes mental abnormality. population with depression are found to have low levels of serotonin in their brains and people with schizophrenia are found to have towering levels of dopamine in their brains. However psychologists cant estab lish whether its the change in chemicals whi! ch causes the abnormality or whether the abnormality...If you want to get a to the full essay, order it on our website:
