Mental Health: Types of Mental Illness, Diagnosis, Treatment

Mental health refers to your emotional and psychological well-being. Having good mental health helps you lead a relatively happy and healthy life. It helps you demonstrate resilience and the ability to cope in the face of life’s adversities. Your mental health can be influenced by a variety of factors, including life events or even your genetics.
Mental health statistics
Mental health issues are common in the United States. About one in five American adults experience at least one mental illness each year. And around one in five young people ages 13 to 18 experience a mental illness at some point in their lives, too. Although mental illnesses are common, they vary in severity. About one in 25 adults experience a serious mental illness (SMI) each year. An SMI can significantly reduce your ability to carry out daily life. Different groups of people experience SMIs at different rates.
According to the National Institute of Mental Health, women are more likely to experience SMI than men. Those ages 18 to 25 are most likely to experience an SMI. People with a mixed-race background are also more likely to experience an SMI than people of other ethnicities.
Mental health disorders
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) helps mental health professionals diagnose mental illnesses. There are many types of mental health disorders. In fact, almost 300 different conditions are listed in DSM-5. These are some of the most common mental illnesses affecting people in the United States:
Generalized anxiety disorder
Generalized anxiety disorder (GAD) goes beyond regular everyday anxiety, like being nervous before a presentation. It causes a person to become extremely worried about many things, even when there’s little or no reason to worry.
Those with GAD may feel very nervous about getting through the day. They may think things won’t ever work in their favor. Sometimes worrying can keep people with GAD from accomplishing everyday tasks and chores. GAD affects about 3 percent of Americans every year.
Post-traumatic stress disorder (PTSD)
Post-traumatic stress disorder (PTSD) is a mental illness that’s triggered after experiencing or witnessing a traumatic event. Experiences that can cause PTSD can range from extreme events, like war and national disasters, to verbal or physical abuse.
Symptoms of PTSD may include flashbacks or being easily startled. It’s estimated that 3.5 percent of American adults experience PTSD.
Schizophrenia
Schizophrenia impairs a person’s perception of reality and the world around them. It interferes with their connection to other people. It’s a serious condition that needs treatment. They might experience hallucinations, have delusions, and hear voices. These can potentially put them in a dangerous situation if left untreated. It’s estimated that 1 percent of the American population experiences schizophrenia.
Coping with mental illnesses
The symptoms of many mental illnesses may get worse if they’re left untreated. Reach out for psychological help if you or someone you know may have a mental illness. If you’re unsure where to start, visit your primary care doctor. They can help with the initial diagnosis and provide a referral to a psychiatrist. It’s important to know that you can still have a full and happy life with a mental illness. Working with a therapist and other members of your mental health team will help you learn healthy ways to manage your condition.
