Types of Depression
Several illnesses and conditions may cause symptoms of depression. Without a complete history, bipolar depression may be mistaken for major depressive disorder. An accurate diagnosis is an important first step toward receiving appropriate care.
Bipolar disorder can be missed as a diagnosis because the symptoms of bipolar depression—the phase that people with the illness tend to spend most of their time in when they are ill—are similar to those of other types of depression.
However, to be diagnosed with bipolar disorder a person must have experienced a high period (mania or hypomania) as well. Be sure to give your doctor an accurate description of all your experiences and symptoms. This can help ensure you have an accurate diagnosis and are getting the appropriate treatment for your symptoms.
Bipolar Depression or Major Depressive Disorder?
Many people with bipolar disorder initially seek treatment for their depressive symptoms rather than for their manic symptoms. Unfortunately, the diagnosis of bipolar disorder is oftentimes missed, since it’s the manic or hypomanic episodes that differentiate bipolar disorder from major depressive disorder.
In a national survey, over one-third of people with bipolar disorder who were originally misdiagnosed waited 10 years or more before receiving an accurate diagnosis. And more than two-thirds of people with bipolar disorder were originally misdiagnosed with other disorders.
The consequences of an inaccurate or delayed diagnosis can be significant. For example, treatment with antidepressants alone, such as SSRIs (selective serotonin reuptake inhibitors) or SNRIs (serotonin-norepinephrine reuptake inhibitors), can trigger a manic episode. And delayed proper treatment for bipolar disorder can mean future episodes, and marital, work, and financial problems.
