Symptoms of Manic Depression
Anxiety, Irritability, and Agitation in Bipolar Mania
Manic depression, also known as bipolar disorder, is characterized by alternating episodes of mania and depression. During manic episodes, patients often exhibit symptoms such as anxiety, irritability, and agitation. These symptoms are prevalent among patients with bipolar I disorder (BD-I) experiencing mania with depressive symptoms. In a study involving 960 patients, 61.4% had anxiety, 62.4% had irritability, and 76.4% had agitation. Notably, 34% of these patients exhibited all three symptoms, indicating severe anxiety, irritability, and agitation (AIA)1. These symptoms are more common in patients with depressive symptoms and can significantly impact the likelihood of remission during treatment1.
Early Symptoms and Prodromes
Identifying early symptoms or prodromes of manic and depressive episodes is crucial for managing bipolar disorder. Research indicates that at least 80% of individuals with mood disorders can identify one or more prodromal symptoms. Early symptoms of mania, such as sleep disturbances, are more frequently recognized compared to early symptoms of depression. The duration of manic prodromes is generally longer than depressive prodromes, with manic prodromes lasting over 20 days on average, while depressive prodromes last less than 19 days2. This early identification can help in timely intervention and management of the disorder.
Impulsivity and Manic Symptoms During Depressive Episodes
Manic symptoms can also occur during depressive episodes in bipolar disorder. These symptoms are often associated with increased impulsivity, which can lead to risky behaviors such as substance abuse and suicidal behavior. In a study of 56 bipolar I or II depressed subjects, manic symptoms were found to correlate significantly with anxiety and psychosis, but not with depression. This suggests a separate psychopathological mechanism at play. Increased impulsivity and a history of substance abuse or suicide attempts were more common in patients with higher Mania Rating Scale (MRS) scores3.
Mixed Features in Major Depressive Disorder
Manic symptoms below the threshold for hypomania, known as mixed features, are common in individuals with major depressive disorder (MDD). These mixed features are associated with severe depression, increased risk of recurrence, suicide attempts, substance abuse, and functional disability. A study evaluating the efficacy of lurasidone in treating MDD with mixed features found significant improvement in depressive and manic symptoms, indicating the potential for effective treatment of this complex condition4.
Co-occurrence of Manic and Depressive Symptoms
The co-occurrence of manic and depressive symptoms is common in bipolar disorder. In a cross-sectional analysis of 441 individuals with bipolar disorder, 94.1% of those with (hypo)mania had clinically significant depressive symptoms, while 70.1% of those in a depressive episode had clinically significant manic symptoms. This co-occurrence is associated with a worse quality of life and suggests that depressive and manic symptoms are positively correlated rather than inversely5.
Patterns of Manic/Hypomanic Symptoms in Depression
Manic or hypomanic symptoms can also be present in patients with major depressive disorder. A study involving 188 patients used a modified screening instrument to assess current manic/hypomanic symptoms. The analysis identified three factors: elation-disinhibition-increased goal-directed activity, risk-taking-impulsivity-substance use, and distractibility-irritability. These findings highlight the presence of manic symptoms in depression and the need for comprehensive assessment tools6.
Conclusion
Manic depression involves a complex interplay of manic and depressive symptoms. Anxiety, irritability, and agitation are common during manic episodes, while impulsivity and mixed features can complicate depressive episodes. Early identification of prodromal symptoms and understanding the co-occurrence of manic and depressive symptoms are crucial for effective management. Comprehensive assessment and targeted treatment strategies are essential to improve the quality of life for individuals with bipolar disorder.

Bipolar disorder is characterized by dramatic "highs" and "lows" (manic and depressive episodes) that can last hours or weeks, with a greater risk of suicide than the general population.

Manic and hypomanic symptoms can be differentiated, and few manic symptoms, particularly psychomotor agitation, are present in major depressive disorders.

Manic symptoms often accompany bipolar depressive episodes, making subsyndromal manic symptoms a more common, severe, and complex clinical state than pure bipolar depression.
Observational StudyHighly CitedAre manic symptoms that 'dip' into depression the essence of mixed features?
Distractibility, irritability, and psychomotor agitation are key symptoms of mixed depressive states in mood disorders, and their exclusion from the DSM-5 may be a mistake.
