Bipolar Affective Disorder ICD-10: One’s mood may be sky high. Then you will have a lot of energy and feel extremely apt. As a spin-off, you can overestimate yourself. One may also be irritable abnormally. For instance, you might be very talkative, restless, or require little sleep.

You can also be depressive due to bipolar disorder. Your mood is then low. You feel very low, for instance, and you stop enjoying things. You may feel weary and find everyday activities harder than before. You can lose interest in things that you previously enjoyed. They may also be finding it harder to focus, and they may have lost confidence in themselves.
Disorders of Mood Affective (F30-F39)
The underlying problem with these disorders is an alteration in affect or mood, whether it be to depression (with or without accompanying anxiety) or to joy. In most cases, a change in mood is accompanied by a change in the general degree of activity; the majority of other symptoms are either secondary to or readily understood in the context of the shift in mood and activity.
The majority of these illnesses are often recurring, and the start of each episode can frequently be linked to stressful events or circumstances.
Manic Episode of The F30
This category should only be utilized for a single episode at a time across all of its subdivisions. A bipolar affective disorder (F31.-) should be diagnosed in people who have had one or more prior affective episodes (depressive, hypomanic, manic, or mixed) and now experience hypomanic or manic episodes. Including: bipolar illness, single manic episode
Hypomania, F30.0
A condition defined by a continuous, moderate increase in mood, higher energy and activity levels, and generally strong emotions of well-being and improved physical and mental performance. An increase in sexual desire, sociability, talkativeness, over-familiarity, and a reduced need for sleep are frequently seen, but not to the point where they cause major workplace disturbance or social ostracism.
Instead of the typical euphoric sociability, irritability, arrogance, and rude behavior can take its place. Hallucinations and delusions do not coexist with the mood and behavioral disturbances.
Mania in The Absence of Psychotic Symptoms (F30.1)
The patient’s mood might swing between extreme excitement and joyful carelessness, which is disproportionate to their situation. Higher energy levels accompany elation, which leads to pressure in speaking, excessive activity, and a reduced need for sleep.
It is difficult to maintain attention, and there is frequently significant distractibility. Grandiose notions and excessive optimism frequently inflate self-esteem. Behavior that is impulsive, foolish, or out of character may be caused by a loss of normal social inhibitions, which can be inappropriate for the situation.
F30.2 Mania with Psychotic Features
Delusions, which are often grandiose, or hallucinations, which are usually of voices speaking directly to the patient, are present in addition to the clinical presentation outlined in F30.1, or the exhilaration, excessive motor activity, and flight of ideas are so extreme that the subject is incomprehensible or inaccessible to ordinary communication.
Mania accompanied by:
- psychotic symptoms that are consistent with one’s mood
- psychotic symptoms that don’t match the mood
A manic state of mind
F30.8 Other manic incidents
Unidentified manic episode, F30.9
NOS Mania
Bipolar affective illness, F31

A condition characterized by two or more episodes during which the patient’s mood and activity levels are severely affected, with the disturbance sometimes consisting of a mood elevation accompanied by increased energy and activity, and at other times consisting of a mood depression accompanied by decreased energy and activity.
Repeated episodes of hypomania or mania alone are considered to be bipolar.
Included:
- Manic depression
- manic-depressive ailment
- psychosis
- response
Cyclothymia (F34.0), bipolar disorder, and a single manic episode (F30.-) are excluded.

Episodes of Depression at F32
Patients experience a decline in mood, a loss of energy, and a reduction in activity during a typical mild, moderate, or severe depressive episode. After even minimal effort, there is often significant weariness, as well as diminished capacity for enjoyment, curiosity, and focus.
Sleep is often disrupted, and appetite is suppressed. Even in its mildest form, some notions of guilt or worthlessness are frequently present, and self-esteem and self-confidence are almost always diminished.
The decreased mood doesn’t fluctuate much from day to day, doesn’t respond to events, and might be accompanied by so-called “somatic” symptoms like loss of interest and pleasurable sensations, waking up many hours earlier than usual in the morning, depression that is at its worst in the morning, significant psychomotor retardation, restlessness, loss of appetite, weight loss, and loss of libido.
A depressive episode may be categorized as mild, moderate, or severe based on the quantity and intensity of symptoms. This includes single episodes of:
- Response to depression
- Depression caused by psychological factors
- Reactive despair
Except: recurrent depressive illness (F33.-) and adjustment disorder (F43.2) when linked to behavior problems in F91.- (F92.0)
Moderate depressive episode at F32.0
Typically, two or three of the symptoms mentioned above manifest themselves. Even though they are usually upset by these, the patient will likely be able to carry on with the majority of their activities.
Moderate depressive episode, F32.1
Typically, four or more of the symptoms listed above are present, and the patient is probably experiencing significant challenges in carrying out daily tasks.
A severe depressive episode that lacks psychotic features (F32.2)
A depressive episode characterized by a number of the aforementioned symptoms, notably a loss of self-esteem and thoughts of worthlessness or guilt, that are often severe and upsetting. In addition to several “somatic” symptoms, suicidal ideation and behavior are frequent.
Significant depression, agitated depression, and a single occurrence of major depression without psychotic features
A major depressive episode with psychotic features is described by F32.3
A bout of depression as described in F32.2, but with the presence of hallucinations, delusions, psychomotor retardation, or stupor so severe that normal social interaction is impossible; there may be risk to life from suicide, dehydration, or starvation. Hallucinations and delusions might be mood-congruent or not. Single occurrences of:
- severe depression accompanied by psychotic features
- psychogenic depressive psychosis
- depression that is psychotic
- depressive psychosis that responds to stimuli

Depressive illness, not otherwise specified (NOS)
Recurrent depressive disorder F33
A condition characterized by recurrent episodes of depression as defined for depressive episode (F32.-), without any history of independent episodes of mood elevation and increased energy (mania). Immediately following a depressive episode, though, there may be brief instances of moderate mood improvement and hyperactivity (hypomania), which are occasionally brought on by antidepressant therapy.
The more severe forms of recurrent depressive disorder (F33.2 and F33.3) share many similarities with earlier notions of manic-depressive depression, melancholia, vital depression, and endogenous depression. The onset of the first episode can happen at any age, from childhood to old age, and it might be sudden or gradual. The length of the episode can range from a few weeks to several months.
No matter how many depressive episodes a patient with recurrent depressive disorder has had, there is always the chance that they will experience a manic episode. If such an event happens, the diagnosis should be switched to bipolar affective disorder (F31.-).
Incl.: recurrent episodes of:
- reaction to depression
- depression caused by psychological factors
- depression that is reactive
- seasonal depressive disorder
Excl.: recurrent short depressive episodes (F38.1)

Sometimes, a persistent mood illness can be characterized by repeated or isolated episodes of mania or depression.
Cyclothymia is known as F34.0
A persistent mood instability characterized by multiple episodes of mild joy and depression, none of which is severe or lasting enough to warrant a diagnosis of recurrent depressive disorder (F33.-) or bipolar affective disorder (F31.-).
