- Infection
- sometimes an infection that causes one illness can lead to a secondary illness that has psychological symptoms
- syphilis - causes short-lived sores followed by general forgetfulness and mental deterioration
- influenza virus has been linked to schizophrenia, research has has shown schizophrenic cases may be linked to the foetus being exposed to the virus in the womb
- Neurotransmitter imbalance
- certain neurotransmitters have been thought to contribute to many psychological disorders
- excessive dopamine - schizophrenia
- low levels of serotonin - depression
- Genetics
- individuals may inherit a predisposition to certain illnesses - these are carried on genes and pass from one gen to the next
- concordance rate - measures how often two individuals, who are closely related, have the same disorder
- Limitations
- Genetics don't provide a complete explanation - environmental influences are equally important as shown by concordance rates
- it is possible that what is inherited is a vulnerability to the disorder which only develops under certain stressful conditions
- the approach focuses on curing the symptoms not the cause of the disorder
- Genetics don't provide a complete explanation - environmental influences are equally important as shown by concordance rates
- Brain damage
