Many people become depressed at some point in their lives, but when these feelings interfere with an individual's ability to live a normal life and persist for an extended period, the individual should seek professional help. Some individuals not only experience depression but also extreme highs, known as mania, making it more difficult to live a normal, productive life. Write a 700- to 1,050-word paper outlining the differences between unipolar and bipolar disorders. Address the underlying causes of unipolar and bipolar disorders. What symptoms would indicate that an individual may be suffering from a unipolar or bipolar disorder? What treatments are available for individuals who suffer from unipolar or bipolar disorders? Provide at least two references to support your research. Format your paper consistent with APA guidelines.
