Mental illness - Symptoms and causes


Mental illness, also called mental health disorders, refers to a wide range of mental health conditions — disorders that affect your mood, thinking and behavior. Examples of mental illness include depression, anxiety disorders, schizophrenia, eating disorders and addictive behaviors.

Many people have mental health concerns from time to time. But a mental health concern becomes a mental illness when ongoing signs and symptoms cause frequent stress and affect your ability to function.

A mental illness can make you miserable and can cause problems in your daily life, such as at school or work or in relationships. In most cases, symptoms can be managed with a combination of medications and talk therapy (psychotherapy).

If your loved one shows signs of mental illness, have an open and honest discussion with him or her about your concerns. You may not be able to force someone to get professional care, but you can offer encouragement and support. You can also help your loved one find a qualified mental health professional and make an appointment. You may even be able to go along to the appointment.

If your loved one has done self-harm or is considering doing so, take the person to the hospital or call for emergency help.

Mental illnesses, in general, are thought to be caused by a variety of genetic and environmental factors:

  • Inherited traits. Mental illness is more common in people whose blood relatives also have a mental illness. Certain genes may increase your risk of developing a mental illness, and your life situation may trigger it.
  • Environmental exposures before birth. Exposure to environmental stressors, inflammatory conditions, toxins, alcohol or drugs while in the womb can sometimes be linked to mental illness.
  • Brain chemistry. Neurotransmitters are naturally occurring brain chemicals that carry signals to other parts of your brain and body. When the neural networks involving these chemicals are impaired, the function of nerve receptors and nerve systems change, leading to depression and other emotional disorders.

Risk factors

Certain factors may increase your risk of developing a mental illness, including:

  • A history of mental illness in a blood relative, such as a parent or sibling
  • Stressful life situations, such as financial problems, a loved one's death or a divorce
  • An ongoing (chronic) medical condition, such as diabetes
  • Brain damage as a result of a serious injury (traumatic brain injury), such as a violent blow to the head
  • Traumatic experiences, such as military combat or assault
  • Use of alcohol or recreational drugs
  • A childhood history of abuse or neglect
  • Few friends or few healthy relationships
  • A previous mental illness

Mental illness is common. About 1 in 5 adults has a mental illness in any given year. Mental illness can begin at any age, from childhood through later adult years, but most cases begin earlier in life.

The effects of mental illness can be temporary or long lasting. You also can have more than one mental health disorder at the same time. For example, you may have depression and a substance use disorder.


Mental illness is a leading cause of disability. Untreated mental illness can cause severe emotional, behavioral and physical health problems. Complications sometimes linked to mental illness 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's no sure way to prevent mental illness. However, if you have a mental illness, taking steps to control stress, to increase your resilience and to boost low self-esteem may help keep your symptoms under control. Follow these steps:

  • Pay attention to warning signs. Work with your doctor or therapist to learn what might trigger your symptoms. Make a plan so that you know what to do if symptoms return. Contact your doctor or therapist if you notice any changes in symptoms or how you feel. Consider involving family members or friends to watch for warning signs.
  • Get routine medical care. Don't neglect checkups or skip visits to your primary care provider, especially if you aren't feeling well. You may have a new health problem that needs to be treated, or you may be experiencing side effects of medication.
  • Get help when you need it. Mental health conditions can be harder to treat if you wait until symptoms get bad. Long-term maintenance treatment also may help prevent a relapse of symptoms.
  • Take good care of yourself. Sufficient sleep, healthy eating and regular physical activity are important. Try to maintain a regular schedule. Talk to your primary care provider if you have trouble sleeping or if you have questions about diet and physical activity.

Know the Warning Signs | NAMI: National Alliance on Mental Illness

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 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
  • Changes in sex drive
  • 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
  • Multiple physical ailments without obvious causes (such as headaches, stomach aches, vague and ongoing “aches and pains”)
  • Thinking about suicide
  • Inability to carry out daily activities or handle daily problems and stress
  • An intense fear of weight gain or concern with appearance

Mental health conditions can also begin to develop in young children. Because they’re still learning how to identify and talk about thoughts and emotions, their most obvious symptoms are behavioral. Symptoms in children may include the following:

  • Changes in school performance
  • Excessive worry or anxiety, for instance fighting to avoid bed or school
  • Hyperactive behavior
  • Frequent nightmares
  • Frequent disobedience or aggression
  • Frequent temper tantrums

Reach out to your health insurance, primary care doctor or state/county mental health authority for more resources.

Contact the NAMI HelpLine to find out what services and supports are available in your community. 

If you or someone you know is struggling or in crisis, help is available. Call or text 988 or chat to reach the 988 Suicide & Crisis Lifeline.

The manual lists criteria including feelings and behaviors and time limits in order to be officially classified as a mental health condition.

After diagnosis, a health care provider can help develop a treatment plan that could include medication, therapy or other lifestyle changes.

Getting a diagnosis is just the first step; knowing your own preferences and goals is also important. Treatments for mental illness vary by diagnosis and by person. There’s no “one size fits all” treatment. Treatment options can include medication, counseling (therapy), social support and education.
