Some mental illnesses have been linked to abnormality of chemicals in the brain, called neurotransmitters, which help brain cells to communicate with each other. Imbalance, deficiency, or improper function in these chemicals may result in faulty transmission of messages in the brain and lead to symptoms of mental illness.
Disorders in brain development of the foetus, or trauma that occurs at the time of birth -- such as loss of oxygen to the brain -- may be a factor in the development of certain conditions, such as autism.
Injury to the brain, such as head injury, or defects in certain areas of the brain, such as due to defective blood supply, may also cause a disorder in function of the mind.
Psychological factors that may contribute to mental illness include:
Long-term abuse of alcohol and drugs has been linked to anxiety, depression, and paranoia.
Poor nutrition and exposure to toxins, such as lead, may play a role in the development of mental illnesses.
Many mental disorders run in families. Susceptibility to certain mental disorders is passed on through genes to children. However, disorders of mental function are linked to abnormalities in many genes and not just one gene. Therefore a person only inherits a susceptibility to a mental disorder and does not develop the illness till certain triggering factors in life, such as stress, drug or alcohol abuse, or a traumatic event, occur.
Certain stressors can trigger an illness in a person who is susceptible to mental illness. These include:
