Abstract
Depressive and bipolar disorders are medical conditions which are often first diagnosed and treated in primary care settings [1, 2]. Hence, family physicians are in a frontline position to provide optimal care for patients who suffer from these disorders. This chapter will provide succinct and practical information on the diagnosis and most effective pharmacologic and nonpharmacologic treatments of these disorders in a primary care setting. Newer therapies, such as deep brain stimulation and special populations, will also be discussed.
