The complete bipolar spectrum includes the a range of mood disorders, ranging from recurrent unipolar depression all the way to bipolar disorder with psychotic features (or schizobipolar disorder).

According to KR Jamison in Touched with Fire, "The ... reality of manic-depressive illness is far more lethal and infinitely more complex than the current psychiatric nomenclature, bipolar disorder, would suggest. Cycles of fluctuating moods and energy levels serve as a background to constantly changing thoughts, behaviors, and feelings. The illness encompasses the extremes of human experience. Thinking can range from florid psychosis, or "madness," to patterns of unusually clear, fast and creative associations, to retardation so profound that no meaningful mental activity can occur. Behavior can be frenzied, expansive, bizarre, and seductive, or it can be seclusive, sluggish, and dangerously suicidal. Moods may swing erratically between euphoria and despair or irritability and desperation. The rapid oscillations and combinations of such extremes result in an intricately textured clinical picture."

A simple nomenclature system was introduced in 1978, although there are others, by Angst, J., et al, to easier label individuals' affectedness within the spectrum, following a clinical study by the Psychiatric University Clinic of Zurich.

Points on the spectrum using this nomenclature are denoted using the following codes:

• 'M' severe mania
• 'D' severe depression (unipolar depression)
• 'm' less severe mania (hypomania)
• 'd' less severe depression

Thus, 'mD' represents a case with hypomania and major depression. A further distinction is sometimes made in the ordering of the letters, to represent the order of the episodes, where the patient's normal state is euthymic, interrupted by episodes of mania followed by depression ('MD') or vice versa ('DM'). This article is about the medical condition. ... It is common to feel sad, discouraged , or down once in a while, and anyone in this state might say they are suffering from depression. ... Hypomania is a state involving combinations of: elevated mood, irritability, racing thoughts, people-seeking, hypersexuality, grandiose thinking, religiosity, and pressured speech. ... Euthymia is a word used for indicating a normal non-depressed, reasonably positive mood. ...

On this scale, major depression would be denoted as 'D'. Unipolar mania ('M') is, depending on the authority cited, either very rare, or nonexistent with such cases actually being 'Md'.

Unipolar hypomania ('m') without accompanying depression is not observed in the medical literature. There is speculation as to whether some high-achieving individuals are actually 'm', with their successful social functioning keeping them out of sight of the mental health profession.

Although it is officially considered a personality disorder rather than an affective/mood disorder, some experts advocate adding borderline personality disorder (BPD) to the bipolar spectrum. BPD has a lot of similarities to rapid-cycling bipolar type II and other depressive disorders, and many patients show a positive response to the same types of medication. Personality disorders form a class of mental disorders that are characterized by long-lasting rigid patterns of thought and behaviour. ... The affective spectrum is a grouping of related psychiatric and medical disorders which may accompany bipolar, unipolar, and schizoaffective disorders at statistically higher rates than would normally be expected. ... A mood disorder is a condition where the prevailing emotional mood is distorted or inappropriate to the circumstances. ... Borderline personality disorder (BPD) is defined within psychiatry, and some other fields, as a disorder characterized primarily by emotional dysregulation, extreme black and white thinking in some areas, and disrupted relationships. ... Oral medication A medication is a licenced drug taken to cure or reduce symptoms of an illness or medical condition. ...
