In general, it is thought that mental illnesses are caused by a variety of genetic and environmental factors:

  • inherited traits. In people whose blood relatives also have a mental illness, mental illness is more common. Some genes may increase your risk of developing a mental illness, and that may trigger your life situation.
  • Eco- prior to birth. Exposure to environmental stressors, infectious factors, toxins, alcohol or drugs when mental illness may often be associated in the womb.
  • Chemistry inside the brain. Naturally occurring neurotransmitters are brain chemicals that bring messages to other parts of the brain and body. The role of nerve receptors and nervous systems changes as the neural networks containing these chemicals are disrupted, leading to depression and other mental disorders.


Mental disorder is one of the principal causes of disability. Untreated mental illness can cause severe problems in social, behavioral, and physical health. Complications related to mental illness often include:

  • Unhappiness and decreased enjoyment of life
  • Family conflicts
  • Relationship difficulties
  • Social isolation
  • Problems with tobacco, alcohol and other drugs
  • Missed work or school, or other problems related to work or school
  • Legal and financial problems
  • Poverty and homelessness
  • Self-harm and harm to others, including suicide or homicide
  • Weakened immune system, so your body has a hard time resisting infections
  • Heart disease and other medical conditions


There is not really a way to prevent mental health diseases/issues but some precautions can be taken:

  • Seek and ask for help.
  • Talk to one of your loved ones about your issues.
  • Seek help from your primary care provider.
  • Call a mental health specialist(if you have or know one.)
  • Call your local emergency number.
  • Pay attention to warning signs(learn what might trigger your symptoms and talk to your doctor or therapist about them).
  • Take good care of yourself(have a healthy lifestyle).
