New screening instruments, such as the rapid mood screener and bipolarity index, have higher accuracy in detecting both bipolar 1 and bipolar 2.
The proposed cognitive subtype of depression is characterized by slow processing speed, insomnia, and reduced activity in cognitive control circuits, requiring alternative treatment options.

The Importance of Screening for Bipolar Disorder
Regularly screening for bipolar disorder is crucial as it can be easily missed. The mood disorder questionnaire is a popular screening tool, although it is more effective in identifying bipolar 1 than bipolar 2. Newer screening instruments, such as the rapid mood screener and bipolarity index, look beyond symptoms and also consider signs of bipolar disorder. These new instruments have shown higher accuracy in detecting both bipolar 1 and bipolar 2.
While symptoms are important in diagnosing bipolar disorder, signs play a crucial role as well. Certain signs, including age of onset, recurrence of depression, treatment response, and family history, can help distinguish bipolar disorder from other conditions. Newer screening instruments, such as the rapid mood screener and Bipolarity Index, take these signs into account, providing more accurate diagnoses. By using comprehensive tools that consider both symptoms and signs, clinicians can improve their ability to identify bipolar disorder.
The Cognitive Subtype of Depression
A cognitive subtype of depression has been proposed, characterized by slow processing speed, insomnia, poor psychosocial functioning, and reduced activity in cognitive control circuits. Patients with this subtype often experience difficulties with response inhibition. Antidepressant treatments may have less effectiveness for this cognitive subtype, but alternative options such as TMS therapy, vortioxetine, modafinil, and behavioral approaches like aerobic exercise and CBT insomnia may be beneficial. Further research is needed to better understand and develop targeted interventions for this specific cognitive subtype.
