Although the exact cause of most mental illnesses is not known, it is becoming clear through research that many of these conditions are caused by a combination of biological, psychological, and environmental factors.
Biological factors; Some mental illnesses have been linked to abnormal functioning of nerve cell circuits or pathways that connect particular brain regions. Nerve cells within these brain circuits communicate through chemicals called neurotransmitters. In addition, genetics, infections, brain defects or injury and prenatal damage are other biological factors that may cause mental illness.
Psychological factors that may contribute to mental illness include:
- Severe psychological trauma suffered as a child, such as emotional, physical, or sexual abuse
- An important early loss, such as the loss of a parent
- Neglect
- Poor ability to relate to others
Certain environmental stressors can trigger an illness in a person who is susceptible to mental illness. These stressors include:
- Death or divorce
- A dysfunctional family life
- Feelings of inadequacy, low self-esteem, anxiety, anger, or loneliness
- Changing jobs or schools. etc.
