Mental health is all about how people think, feel, and behave. Mental health specialists can help people with depression, anxiety, bipolar disorder, addiction, and other conditions that affect their thoughts, feelings, and behaviors.
Mental health can affect daily living, relationships, and physical health.
However, this link also works in the other direction. Factors in people’s lives, interpersonal connections, and physical factors can contribute to mental ill health.
Looking after mental health can preserve a person’s ability to enjoy life. Doing this involves balancing life activities, responsibilities, and efforts to achieve psychological resilience.
Stress, depression, and anxiety can all affect mental health and disrupt a person’s routine.
Although health professionals often use the term mental health, doctors recognize that many psychological disorders have physical roots.
This article explains what people mean by mental health and mental illness. We also describe the most common types of mental disorders, including their early signs and how to treat them.
“Mental health is a state of mental well-being that enables people to cope with the stresses of life, realize their abilities, learn well and work well, and contribute to their community.”
The WHO states that mental health is “more than just the absence of mental disorders or disabilities.” Peak mental health is not only about managing active conditions but also looking after ongoing wellness and happiness.
It also emphasizes that preserving and restoring mental health is crucial individually and at a community and society level.
In the United States, the National Alliance on Mental Illness estimates that almost 1 in 5 adults experience mental health problems each year.
In 2020, an estimated 14.2 million adults Trusted Source in the U.S., or about 5.6%, had a serious psychological condition, according to the National Institute of Mental Health (NIMH).
Risk factors for mental health conditions
Everyone is at some risk of developing a mental health disorder, regardless of age, sex, income, or ethnicity. In the U.S. and much of the developed world, mental disorders are one of the leading causes of disability.
Social and financial circumstances, adverse childhood experiences, biological factors, and underlying medical conditions can all shape a person’s mental health.
Many people with a mental health disorder have more than one condition at a time.
It is important to note that good mental health depends on a delicate balance of factors and that several elements may contribute to developing these disorders.
The following factors can contribute to mental health disruptions.
Continuous social and economic pressure
Having limited financial means or belonging to a marginalized or persecuted ethnic group can increase the risk of mental health disorders.
A 2015 Iranian study Trusted Source describes several socioeconomic causes of mental health conditions, including poverty and living on the outskirts of a large city.
The researchers also described flexible (modifiable) and inflexible (nonmodifiable) factors that affect the availability and quality of mental health treatment for certain groups.
Modifiable factors for mental health disorders include:
- socioeconomic conditions, such as whether work is available in the local area
- a person’s level of social involvement
- housing quality
Nonmodifiable factors include:
The researchers found that being female increased the risk of low mental health status by nearly 4 times. People with a “weak economic status” also scored highest for mental health conditions in this study.
Several studies Trusted Source support that adverse childhood experiences such as child abuse, parental loss, parental separation, and parental illness significantly affect a growing child’s mental and physical health.
There are also associations between childhood abuse and other adverse events with various psychotic disorders. These experiences also make people vulnerable to post-traumatic stress disorder (PTSD).
The NIMH suggests that genetic family history can increase the likelihood Trusted Source of mental health conditions as specific genes and gene variants put a person at higher risk.
However, many other factors contribute to the development of these disorders.
Having a gene associated with a mental health disorder does not guarantee that a condition will develop. Likewise, people without related genes or a family history of mental illness can still have mental health issues.
Chronic stress and mental health conditions such as depression and anxiety may develop due to underlying physical health problems, such as cancer, diabetes, and chronic pain.
No physical test or scan reliably indicates whether a person has developed a mental illness. However, people should look out for the following as possible signs of a mental health disorder:
- withdrawing from friends, family, and colleagues
- avoiding activities they would normally enjoy
- sleeping too much or too little
- eating too much or too little
- feeling hopeless
- having consistently low energy
- using mood-altering substances, including alcohol and nicotine, more frequently
- displaying negative emotions
- being confused
- being unable to complete daily tasks, such as getting to work or cooking a meal
- having persistent thoughts or memories that reappear regularly
- thinking of causing physical harm to themselves or others
- hearing voices
- experiencing delusions
Diagnosing a mental health disorder requires a multi-step process. A doctor may begin by looking at a person’s medical history and performing a thorough physical exam to rule out physical conditions or issues that may be causing the symptoms.
No medical tests can diagnose mental disorders. However, doctors may order a series of laboratory tests such as imaging exams and bloodwork to screen for other possible underlying causes.
They will also do a psychological evaluation. This includes asking about a person’s symptoms, experiences, and how these have impacted their lives. Sometimes, the doctor may ask a person to fill out mental health questionnaires to get an idea about a person’s thoughts, feelings, and behavior patterns.
Most mental health specialists use the American Psychiatric Association’s (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM-5) to make a diagnosis. This manual contains descriptions and specific criteria to qualify for a diagnosis.
There are various methods for managing mental health problems. Treatment is highly individual, and what works for one person may not work for another.
Some strategies or treatments are more successful in combination with others. A person with a chronic mental disorder may choose different options at various stages in their life.
The individual needs to work closely with a doctor who can help them identify their needs and provide suitable treatment.
Below are some treatment options for people with mental ill health.
Psychotherapy, or talking therapies
This type of treatment takes a psychological approach to treating mental illness. Cognitive behavioral therapy (CBT), exposure therapy, and dialectical behavior therapy are examples.
Psychiatrists, psychologists, psychotherapists, and some primary care physicians carry out this treatment.
It can help people understand the root of their mental illness and start to work on more healthful thought patterns that support everyday living and reduce the risk of isolation and self-harm.
Some people take prescribed medications, such as antidepressants, antipsychotics, and anxiolytic drugs.
Although these cannot cure mental disorders, some medications can improve symptoms and help a person resume social interaction and a routine while working on their mental health.
Some of these medications boost the body’s absorption of feel-good chemicals, such as serotonin, from the brain. Other drugs either boost the overall levels of these chemicals or prevent their degradation or destruction.
A person coping with mental health difficulties may need to change their lifestyle to facilitate wellness.
Such changes can include reducing alcohol intake, sleeping more, and eating a balanced, nutritious diet. People may need to take time away from work or resolve issues with personal relationships that may be causing damage to their mental health.
People with conditions such as anxiety or depressive disorder may benefit from relaxation techniques, which include deep breathing, meditation, and mindfulness.
Having a support network, whether via self-help groups or close friends and family, can also be essential to recovery from mental illness.

The prevalence of mental disorders tends to peak in people ages 18–25 Trusted Source, but drops significantly in people aged 50 and over.
Having a mental health problem, especially depression, is strongly associated with severe chronic health conditions such as diabetes, stroke, hypertension, cancer, and heart disease.
