Causes of depression, anxiety,mental illness etc.
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.
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
- Poor ability to relate to others

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:
- Death or divorce
- A dysfunctional family life
- Living in poverty
- Feelings of inadequacy, low self-esteem, anxiety, anger, or loneliness
- Changing jobs or schools
- Social or cultural expectations (For example, a society that associates beauty with thinness can be a factor in the development of eating disorders.)
