Summary
Many depressed patients may have undiagnosed bipolar disorder (BD). Differentiating BD from major depressive disorder (MDD) requires thorough clinical history and screening tools to improve accurate diagnosis.
Area of Science:
- Psychiatry
- Mood Disorders
- Diagnostic Accuracy
Background:
- Bipolar disorder (BD) is a prevalent mood disorder.
- BD is frequently misdiagnosed as unipolar major depressive disorder (MDD).
Purpose of the Study:
- To summarize features distinguishing bipolar disorder from major depressive disorder.
- To improve the diagnostic accuracy of bipolar disorder.
Main Methods:
- A MedLine search was conducted for English-language articles (1996-2006).
- Key search terms included 'bipolar disorder,' 'manic-depression,' and 'major depressive disorder.'
Main Results:
- Twenty-six features were identified to aid in differentiating BD from MDD.
- Effective diagnostic methods include detailed clinical history and self-reported screening tools.
Conclusions:
- Up to 20% of depressed outpatients may have undiagnosed bipolar disorder.
- Enhanced clinical acumen and screening tools can improve BD recognition.

Bipolar Disorder
Bipolar disorder is a chronic mental health condition marked by significant mood fluctuations, including episodes of mania and depression. Elevated energy levels, heightened mood or irritability, impulsive behavior, reduced sleep needs, rapid speech, racing thoughts, inflated self-esteem, and distractibility characterize mania. Individuals with bipolar disorder often alternate between depressive and manic states, with periods of emotional stability lasting an average of six months to a year.
Mania and Antimanic Drugs: Overview
Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as a...
Antidepressant Drugs: MAOIs and Other Agents
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...
Depressive Disorders: MDD and Dysthymia
Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...
Depressive Disorders: Etiology
Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...

Depression: Overview
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...
