1. Assess and discuss the validity of the Model of Abnormality that is consistent with your thinking as to the etiology of depression. Support your ideas with information from the text and reliable websites.

According to the medical model of abnormality, the following biological factors explain diseases, such as depression:

? Genetics. The genes we inherit from our parents provide the 'blueprint' for our bodies and brains. A slight abnormality in the genes could result in abnormalities in a person's brain functioning with the consequence that their behaviour becomes abnormal.
? Infection. The brain itself has no immune response. It relies on keeping infections (e.g. bacteria or viruses) out with a barrier. Infections that get into the brain can cause widespread damage, and if the brain is damaged then a person may start to have abnormal experiences or to behave in abnormal ways.
? Chemicals. To operate properly, the brain relies on hundreds of different chemicals all being in the correct balance. These chemicals (neurotransmitters and hormones) are used to send messages round the brain and nervous system, so too much or too little of any of them can cause the brain to function abnormally ...
