Final answer:
Anxiety disorders have the highest prevalence among the conditions listed, affecting nearly 18 percent of U.S. adults yearly and 28 percent over their lifetime, which includes various types of anxiety-related problems.
Step-by-step explanation:
Among the conditions listed, anxiety disorders have the highest prevalence. In the United States, almost 18 percent of adults may be affected by an anxiety disorder in a single year, and about 28 percent may experience one at some point in their lifetime. Anxiety disorders include a range of issues such as obsessive-compulsive disorder (OCD), panic disorders, posttraumatic stress disorder (PTSD), social phobias, and specific phobias.
Following anxiety disorders are depressive disorders, or mood disorders, which affect roughly 10 percent of U.S. adults annually, with a lifetime prevalence of about 21 percent. Conditions such as major depressive disorder and bipolar disorder fall under this category.
Schizophrenia affects about 1 percent of the population, while the prevalence of dementia increases significantly with age, particularly affecting those over 65. Substance abuse disorders, as characterized in the DSM-5, involve a pattern of compulsive drug use that can lead to significant adverse effects.
