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
