The diagnostic boundary between recurrent unipolar depression and bipolar disorder may not be clear-cut and, further, the symptoms of unipolar depression compared with bipolar depression (although similar) are subtly different. Here we review the potential implications for clinical practice and research of new thinking about the relationship between recurrent unipolar depression and bipolar disorder. 
Diagnosing and treating bipolar disorder in primary care
TLDR
Many patients have undiagnosed bipolar depression, ie, depression with shifts to periods of mania, which is important for prognostic and treatment reasons.
Differential failure to deactivate the default mode network in unipolar and bipolar depression
Neuroimaging studies have revealed evidence of brain functional abnormalities in bipolar depressive disorder (BDD) and major depressive disorder (MDD). However, few studies to date have compared
Is depression one thing or many?
Until 1980, manic depressive illness (MDI) was defined as follows: the presence of recurrent severe depressive or manic episodes alternating with periods of normal mood or markedly decreased mood
Bipolar I and II versus unipolar depression: Clinical differences and impulsivity/aggression traits
Distinct resting‐state perfusion patterns underlie psychomotor retardation in unipolar vs. bipolar depression
TLDR
Psychomotor abnormalities characterize both unipolar (UP) depression and bipolar (BP) depression in terms of motor activity and resting‐state cerebral blood flow and their association in BP, UP, and healthy controls (HC).
A Comparative Study of Depressive Episode in Major Depressive Disorder and Bipolar Disorder
Distinguishing between major depressive disorder (MDD) and bipolar disorder is important because there are differences in the optimal management of these conditions. Antidepressant treatment of
A Comparative Study on Clinical Profile and Substance Use of Patients with Bipolar Versus Unipolar Depression
TLDR

TLDR
The choice and use of medicines in the management of bipolar affective disorder are discussed, and Pharmacology, interactions and side‐effects, as well as information to give to patients are described.
Reward and Punishment Sensitivity and Emotion Regulation Processes Differentiate Bipolar and Unipolar Depression
TLDR
The data suggest that patterns of affective responding previously linked to underlying risk for mania in BD may remain evident during a major depressive episode, and current models of reward sensitivity inBD may benefit from the inclusion of punishment sensitivity and behavioral avoidance, particularly with respect to bipolar depression.

Clinical differences between bipolar and unipolar depression

TLDR
Rather than proposing a categorical diagnostic distinction between bipolar I depression and major depressive disorder, this paper would recommend a 'probabilistic' (or likelihood) approach.

TLDR
The significance of the depressed phase of bipolar disorder has been markedly underestimated and appears to be the major contributant to the disability related to this condition.

TLDR
The classification of recurrent mood disorders is in need of review and the importance of examining the conceptual assumptions of contemporary psychiatric nosology is well illustrated by the diagnostic complexity of bipolar disorders.

TLDR
The HCL-32 and BSDS screening questionnaires may be more useful for detecting broader definitions of bipolar disorder than DSM-IV-defined bipolar disorder.
