The Biological Approach & Therapies
The most widely used approach to the causes and treatment of mental illnesses in the western world.
- A Physical Cause - abnormal behaviour is compared to a disease and put down to abnormalities that are physical, usually within the brain. it's assumed that all mental illnesses have a physiological cause related to the physical structure and/or functioning of the brain. An example would be a physical abnormality, such as a brain tumour that may cause mental problems such as depression.
- Symptoms - medically physical illnesses have clear-cut symptoms, doctors can diagnose problems because of physical abnormalities.
- Genetic Inheritance - Twin studies, such as Kendler et al 1985 have found that some mental illnesses are hereditary and therefore genetic.
- Drug Therapy - drugs work by entering the bloodstream in order to reach the brain, neurotransmitters affect behaviour, the main ones are; dopamine, serotonin, acetylcholine, noradrenaline and GABA.
- Electro-Convulsive Therapy (ECT) - used when drugs and psychotherapy failed, electrical charge passed through the brain which causes a temporary brain siezure.
