Mental Health Signs & Symptoms

Some Common Symptoms and How to Recognize Them

Trying to tell the difference between what expected behaviors are and what might be the signs of a mental illness isn’t always easy. There’s no easy test that can let someone know if there is a mental illness or if actions and thoughts might be typical behaviors of a person or the result of a physical illness.

Each illness has its own symptoms, but common signs of mental illness in adults and adolescents can include the following:

  • – Excessive worrying or fear
  • – Feeling excessively sad or low
  • – Confused thinking or problems concentrating and learning
  • – Extreme mood changes, including uncontrollable “highs” or feelings of euphoria
  • – Prolonged or strong feelings of irritability or anger
  • – Avoiding friends and social activities
  • – Difficulties understanding or relating to other people
  • – Changes in sleeping habits or feeling tired and low energy
  • – Changes in eating habits such as increased hunger or lack of appetite
  • – Difficulty perceiving reality (delusions or hallucinations, in which a person experiences and senses things that don’t exist in objective reality)
  • – Inability to perceive changes in one’s own feelings, behavior or personality (”lack of insight” or anosognosia)
  • – Overuse of substances like alcohol or drugs
  • – Thinking about suicide
  • – Inability to carry out daily activities or handle daily problems and stress
  • – Intense fear of weight gain or concern with appearance
