Bipolar disorder or bipolar affective disorder ( historically known as manic-depressive disorder ) is a psychiatric diagnosis for a mood disorder in which people experience disruptive mood swings that encompass a frenzied state known as mania ( or hypomania ) and, usually, symptoms of depression.

Bipolar disorder is defined by the presence of one or more episodes of abnormally elevated energy levels, cognition, and mood with or without one or more depressive episodes.

Bipolar disorder may be a polygenic disease.

Bipolar disorder is a condition in which people experience intermittent abnormally elevated ( manic or hypomanic ) and, in many cases, abnormally depressed states for periods of time in a way that interferes with functioning.

Bipolar disorder can appear to be unipolar depression: what distinguishes bipolar disorder from unipolar depression is the presence of mania ( or hypomania ).

Bipolar disorder is also accompanied by changes in cognitive processes and abilities.

Several rating scales for the screening and evaluation of bipolar disorder exist, such as the Bipolar spectrum diagnostic scale.

; Bipolar I disorder: One or more manic episodes.

; Bipolar II disorder: No manic episodes, but one or more hypomanic episodes and one or more major depressive episode.

; Bipolar disorder NOS ( not otherwise specified ): This is a catchall category, diagnosed when the disorder does not fall within a specific subtype.

Bipolar disorder can be a severely disabling medical condition.

" Bipolar disorder is currently regarded " as possibly the most costly category of mental disorders in the United States.

Bipolar disorder can cause suicidal ideation that leads to suicidal attempts.

Bipolar I disorder is a mood disorder that is characterized by at least one manic or mixed episode.

Bipolar I disorder sometimes occurs along with episodes of hypomania or major depression as well.

MWC 922, a nebula in the Mount Wilson Catalog, is a Symmetric Bipolar Nebula notable for its appearance as a perfectly symmetrical square or rectangle.

Bipolar transistors can be made to conduct by exposure to light, since absorption of photons in the base region generates a photocurrent that acts as a base current ; the collector current is approximately β times the photocurrent.

Bipolar HVDC lines at which each pole is operated with the same voltage toward ground are also balanced lines.

Due to this being an emotionally charged time, it is not unusual for mood swings to be passed off as hormonal or teenage ups and downs and for a diagnosis of Bipolar Disorder to be missed until there is evidence of an obvious manic / hypomanic phase.

Bipolar percussion is not popular with hobbyists, but there is evidence that bipolar percussion was the preferred way of dealing with certain problems.

Bipolar percussion is often used to break open small cobbles, or to have a second chance with spent lithic cores, broken bifaces, and tools that have been reworked so much that it is impossible to make further useful tools using traditional lithic reduction.

Bipolar depression is generally more pervasive with sleep and appetite disturbances, as well as a marked non-reactivity of mood, whereas mood with respect to borderline personality and co-occurring dysthymia remains markedly reactive and sleep disturbance not acute.

It is possible Xu Wei suffered from Bipolar Disorder, a condition actually recognized in China at this time.

Bipolar disorder is characterized by extreme mood swings, usually between mania and depression

Bipolar junction transistors offer high speed, high gain, and low output resistance, which are excellent properties for high-frequency analog amplifiers, whereas CMOS technology offers high input resistance and is excellent for constructing simple, low-power logic gates.

Bipolar disorder, or manic-depression, is itself comorbid with a number of conditions, including autism.

Bipolar devices are also limited to a fixed power supply voltage, typically 5 V, while CMOS parts often support a range of supply voltages.

Bipolar outflows or jets may also be associated with protostars ( young, forming stars ), or with evolved post-AGB stars ( often in the form of bipolar nebulae )

Bipolar disorder is an often severe mood disorder characterized by periods of days, weeks, or months of deep depression, alternating with periods of normal mood and / or manic episodes, which are not just periods of " high energy " or " productivity ", though these may be a symptom of mania.

Condensation of water produced by a PEMFC on the air channel wall.

Bipolar disorder ( also known as manic depression ) involves abnormally " high " or pressured mood states, known as mania or hypomania, alternating with normal or depressed mood.

That same study also reported that in adult patients with Bipolar 1 disorder who were already receiving either lithium or valproate, the addition of topiramate did not produce a statistically significant improvement versus placebo, while adding the above adverse reactions.

Bipolar systems with both positive and negative cables may also retain a seawater grounding electrode, used when one pole has failed.

The Weitek FPUs were replaced by a floating point chipset made by Bipolar Integrated Technology and a redesigned vector processor with 32 64-bit vector elements, 8 64-bit scalar floating point registers, 8 32-bit integer registers, and 8 32-bit address registers.

Individuals with Bipolar I Disorder experience severe episodes of mania and depression with periods of wellness between episodes.
