Final answer:
Antidepressant drugs, in addition to treating depression, are also commonly used to help manage anxiety disorders and can be used in the treatment of eating disorders.
Step-by-step explanation:
In addition to depression, antidepressant drugs are also used in the treatment of anxiety disorders. These drugs include but are not limited to sertraline, which can treat depression, anxiety, and eating disorders. Anxiety disorders, which affect a significant portion of the adult population in the United States, can also be managed with anxiolytics like buspirone and diazepam. While there are medications for schizophrenia and personality disorders, they often involve other classes of drugs such as antipsychotics and mood stabilizers, not typically categorized as antidepressants.
