Step-by-step explanation:
Mood Disorders
Mood disorders are the second most common mental disorders in the United States, affecting roughly 10 percent of U.S. adults every year. The two major mood disorders are depression and dysthymic disorder. Depression is a long-term, debilitating illness characterized by a severely depressed mood, while dysthymic disorder is a chronic form of depression that lasts for at least two years. Bipolar disorder, formerly known as manic depression, is characterized by dramatic shifts in energy and mood.
Schizophrenia
Schizophrenia is a serious mental illness affecting one percent of people in the United States. It is characterized by symptoms such as hallucinations, delusions, difficulty thinking, and problems with social situations. Treatment for schizophrenia often involves antipsychotic medications that work by blocking dopamine receptors in the brain.
Anxiety Disorders
Anxiety disorders are the most common mental disorders in the United States, affecting almost 18 percent of U.S. adults in a single year. These disorders include obsessive compulsive disorder (OCD), panic disorders, posttraumatic stress disorder (PTSD), and various phobias. It is important to differentiate between occasional feelings of anxiety and a true anxiety disorder, which is characterized by prolonged and excessive worry and fearfulness.
Eating Disorders
Eating disorders are mental health disorders defined by abnormal eating habits that adversely affect health. They are much more common in females than males and have the highest mortality rate among mental disorders. Common types of eating disorders include anorexia nervosa, bulimia nervosa, and binge eating disorder.
