Definition
Mental illness 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 work or in relationships. In most cases, mental illness symptoms can be managed with a combination of medications and counseling (psychotherapy).
Symptoms
Signs and symptoms of mental illness can vary, depending on the particular disorder, circumstances and other factors. Mental illness symptoms can affect emotions, thoughts and behaviors.
Examples of signs and symptoms include:
- Feeling sad or down
- Confused thinking or reduced ability to concentrate
- Excessive fears or worries
- Extreme mood changes of highs and lows
- Withdrawal from friends and activities
- Significant tiredness, low energy or problems sleeping
- Detachment from reality (delusions), paranoia or hallucinations
- Inability to cope with daily problems or stress
- Extreme feelings of guilt
- Alcohol or drug abuse
- Major changes in eating habits
- Sex drive changes
- Excessive anger, hostility or violence
- Suicidal thinking
Sometimes symptoms of a mental health disorder appear as physical problems, such as abdominal pain, back pain, headache, or other unexplained aches and pains.
Is it mental illness?In general, signs and symptoms may indicate a mental illness when they make you miserable and interfere with your ability to function in your daily life. You may have trouble coping with stress, anger or other emotions. Or you may find it difficult to handle family, work or school responsibilities, or have serious legal or financial problems.
With some types of mental illness, though, such as schizophrenia or bipolar disorder, you may not realize the extent of your problems — instead, it may be family members or friends who first become aware that you have a mental illness.
When to see a doctorIf you have any signs or symptoms of a mental illness, see your doctor, mental health provider or other health professional. Most mental illnesses don't improve on their own, and if untreated, a mental illness may get worse over time and cause serious problems.
If you have suicidal thoughtsSuicidal thoughts and behavior are common with some mental illnesses. If you think you may hurt yourself or attempt suicide, get help right away:
- Call 911 or your local emergency number immediately.
- Reach out to a close friend or loved one — even though you may be reluctant to talk about your feelings.
- Contact a minister, spiritual leader or someone in your faith community.
- Contact your doctor, other health care provider or mental health specialist.
Suicidal thinking doesn't get better on its own — so get help.
Helping a loved oneIf 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 seek professional care, but you can offer encouragement and support. You can also help your loved one find a qualified doctor or mental health provider and make an appointment. You may even be able to go along to the appointment.
If your loved one has harmed himself or herself, or is seriously considering doing so, take the person to the hospital, or call for emergency help.
Causes
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 biological (blood) relatives also have a
mental illness. Certain genes may increase your risk of developing a mental
illness, and your life situation may trigger the actual mental illness.
·
Environmental exposures before
birth. Exposure to viruses, toxins, alcohol or drugs while in the
womb can sometimes be linked to mental illness.
·
Negative life experiences. Situations
in your life, such as the loss of a loved one, financial problems and high
stress, can play a role in triggering mental illness. So can an upbringing that
leads to poor self-esteem or a history of sexual or physical abuse. Life
experiences can lead to unhealthy patterns of thinking linked to mental
illness, such as pessimism or distorted ways of thinking.
·
Brain chemistry. Biochemical
changes in the brain are thought to affect mood and other aspects of mental
health. Naturally occurring brain chemicals called neurotransmitters play a
role in some mental illnesses. In some cases, hormonal imbalances affect mental
health. It's thought that inherited traits, life experiences and biological
factors can all affect brain chemistry linked to mental illnesses.

Risk factors
Certain factors may increase
your risk of developing mental health problems, including:
● Having a biological (blood)
relative, such as a parent or sibling, with a
mental illness

● Experiences in the womb —
for example, having a mother who was
exposed to viruses, toxins, drugs or alcohol during pregnancy.
● Experiencing stressful life situations, such as financial problems, a loved
one's death or a divorce.
● Having a chronic medical condition, such as cancer.
● Experiencing brain damage as a result of a serious injury (traumatic brain
injury), such as a violent blow to the head.
● Having traumatic experiences, such as military combat or being assaulted.
● Use of illegal drugs.
● Being abused or neglected as a child.
● Having few friends or few healthy relationships.

o
Mental illness is common.
About 1 in 4 adults has a mental illness in any given year. About half of U.S.
adults will develop a mental illness sometime in their lives. Mental illness
can begin at any age, from childhood through later adult years.
Complications
Mental illness is a leading cause of disability. Aside from
reducing your quality of life, untreated mental illness can cause severe
emotional, behavioral and physical health problems. Mental illness can also
cause legal and financial problems. Complications 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.
● Poverty and homelessness.
● Self-harm and harm to others, including suicide or homicide.
● Increased risk of motor vehicle accidents.
● Weakened immune system, so your body has a hard time resisting colds
and other infections.
● Heart disease and other medical conditions.

Determining which mental illness you have
Sometimes it's difficult to find out which particular mental illness may be causing your symptoms. But taking the time and effort to get an accurate diagnosis will help determine the appropriate treatment.

The defining symptoms for each mental illness are detailed in the
Diagnostic and Statistical Manual of Mental Disorders (DSM) published by the
American Psychiatric Association. Mental health providers use this manual to
diagnose mental conditions, and insurance companies use it to reimburse for
treatment. To be diagnosed with a particular mental illness, you must meet the
criteria listed in the DSM.

Treatments and drugs
Your particular treatment depends on the type of mental illness
you have, its severity and what works best for you. In many cases, a
combination of treatments works best.
If you have a mild mental illness with well-controlled symptoms,
treatment from one health care provider may be sufficient. However, often a
team approach is appropriate to make sure all your psychiatric, medical and
social needs are met. This is especially important for severe mental illnesses,
such as schizophrenia.

● Psychiatrist, a medical
doctor who diagnoses and treats mental illnesses.
● Psychotherapist, such as a
psychologist or a licensed counselor.
● Pharmacist.
● Social worker.
● Family members.
Medications
Although psychiatric medications don't cure mental illness, they can often significantly improve symptoms. Psychiatric medications can also help make other treatments, such as psychotherapy, more effective. The best medications for you will depend on your particular situation and how your body responds to the medication.

Here's an overview of some of the most commonly used classes of
prescription psychiatric medications:
● Antidepressant medications. Antidepressants are
used to treat various
types of depression and sometimes other conditions. Antidepressants can
help improve such symptoms as sadness, hopelessness, lack of energy,
difficulty concentrating and lack of interest in activities. Different types of
antidepressants are grouped by how they affect brain chemistry. The best

most commonly used
to treat bipolar disorder, which is characterized by alternating episodes of
mania and depression. Sometimes mood-stabilizing medications are added
to antidepressants to treat depression.

● Anti-anxiety medications. Anti-anxiety
medications are used to treat
anxiety disorders, such as generalized anxiety disorder and panic disorder.
They may also help reduce agitation and insomnia. These medications are
typically fast acting, helping relieve symptoms in as little as 30 to 60
minutes. A major drawback, however, is that they have the potential to
cause dependency.

Psychotherapy
Psychotherapy, also called talk therapy or psychological counseling, is a process of treating mental illness by talking about your condition and related issues with a mental health provider. During psychotherapy, you learn about your condition and your moods, feelings, thoughts and behavior. Using the insights and knowledge you gain, you can learn coping and stress management skills.

During psychotherapy, you learn about your condition and your moods, feelings, thoughts and behavior. Using the insights and knowledge you gain, you can learn coping and stress management skills.
There are many specific types of psychotherapy, each with its own
approach to improving your mental well-being. Psychotherapy often can be
successfully completed in a few months, but in some cases, long-term treatment
may be helpful. It can take place one-on-one, in a group or along with family
members.
Brain-stimulation treatments
Brain-stimulation treatments are sometimes used for depression and some other mental health disorders. They are generally reserved for situations in which medications and psychotherapy haven't worked. They include electroconvulsive therapy (ECT), transcranial magnetic stimulation, vagus nerve stimulation and an experimental treatment called deep brain stimulation.

Make sure you understand all the risks and benefits of any
recommended treatment.
Hospitalization and residential treatment
programs
Sometimes mental illness becomes so severe that you need psychiatric hospitalization. Hospitalization is generally recommended when you can't care for yourself properly or when you're in immediate danger of harming yourself or someone else. Options include 24-hour inpatient care, partial or day hospitalization, or residential treatment, which offers a supportive place to live. One other option may be intensive outpatient treatment.

Participating in your own care
Working together, you and your health provider can decide which treatment options may be best for you, depending on your symptoms and their severity, your personal preferences, side effects, and other factors. In some cases, a mental illness may be so severe that a doctor, loved one or guardian may need to guide your care until you're well enough to participate in decision making.

Lifestyle and home remedies
In most cases, a mental illness won't get better if you try to
treat it on your own without professional care. But you can do some things for
yourself that will build on your treatment plan:
● Stick to your treatment plan. Don't skip therapy
sessions. Even if you're
feeling better, don't skip your medications. If you stop, symptoms may come
back. You could also have withdrawal-like symptoms if you stop a
medication too suddenly. If you have bothersome medication side effects or
other problems with your treatment, talk to your doctor before making
changes.

● Avoid alcohol and drug use. Using alcohol or
illegal drugs can make it
difficult to treat a mental illness. If you're addicted, quitting can be a real
challenge. If you can't quit on your own, see your doctor or find a support
group to help you.

● Stay active. Exercise can help you manage symptoms such
as depression,
stress and anxiety. Physical activity can also counteract the effects of some
psychiatric medications that may cause weight gain. Consider walking,
jogging, swimming, gardening or taking up another form of physical activity
that you enjoy. Even light physical activity can make a difference.

● Don't make important decisions when your symptoms are severe.
Avoid decision making when you're in the depth of mental illness
symptoms, since you may not be thinking clearly.

● Prioritize your life. You can reduce the
impact of your mental illness by
carefully managing your time and energy. Cut back on obligations when
necessary, and set reasonable goals for yourself. Give yourself permission
to do less when your symptoms are bad. You may find it helpful to make a
list of daily tasks, use sticky notes as reminders, or use a planner to
structure your time and stay organized.

Coping and support
Coping with a mental illness can be challenging. Talk to your
doctor or therapist about improving your coping skills, and consider these
tips:
● Learn about your mental illness. Include your family,
too — this can help
the people who care about you understand what you're going through and
learn how they can help. Your doctor or therapist may provide information
directly or may recommend classes, books or websites.

Prevention
There's no sure way to prevent mental illness. However, if you do
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 in watching for warning signs.
