Disease Category
Bipolar disorder is a mood disorder in which manic and hypomanic episodes and depressive episodes may recur, and changes can occur not only in mood but also in energy, activity, and behavior.
Core Mechanism
The exact cause has not been identified, but it is explained as involving genetic predisposition, brain structure and function, and environmental factors together.
Main Causes · Related Factors
The core of the disease lies in the disruption of mood, arousal, and activity regulation, leading to manic or depressive states, with the degree and duration of recovery between states varying by individual.
Representative Manifestations
Representative patterns include manic/hypomanic episodes characterized by elevated or irritable mood and increased energy; depressive episodes centered on sadness, hopelessness, and loss of interest; or mixed symptoms where both patterns appear together.
Individual Variability
The risk may increase if a close family member has bipolar disorder, and trauma or major stressful events can influence the risk.
Diagnosis
Symptoms vary greatly between individuals, episodes can last for a week or more than two weeks, and bipolar disorder is a condition that requires long-term management.
Management
Diagnosis is made by comprehensively evaluating symptoms, lifelong mood changes, functional changes, and family history, along with physical examinations, necessary medical tests, and mental health assessments.
Treatment/Research Status
It is difficult to confirm based on a single mood state or a single test alone, and other similar causes, such as other medical conditions or substance use, must be differentiated.
Read Evidence
The broad framework of management involves combining pharmacotherapy and psychotherapy tailored to the individual's situation, while monitoring changes in sleep, activity, and mood to reduce the risk of relapse.
Key Precautions
Current treatment aims for symptom control and relapse prevention, and the combination of medication or therapy can be adjusted while monitoring effectiveness and side effects.

At a Glance

How the disease works

The exact cause has not been identified, but it is explained as involving genetic predisposition, brain structure and function, and environmental factors together.

The core of the disease lies in the disruption of mood, arousal, and activity regulation, leading to manic or depressive states, with the degree and duration of recovery between states varying by individual.

Variations in presentation among individuals

The risk may increase if a close family member has bipolar disorder, and trauma or major stressful events can influence the risk.

The broad framework of diagnosis and management

Symptoms vary greatly between individuals, episodes can last for a week or more than two weeks, and bipolar disorder is a condition that requires long-term management.

Diagnosis is made by comprehensively evaluating symptoms, lifelong mood changes, functional changes, and family history, along with physical examinations, necessary medical tests, and mental health assessments.

Current status of treatment

It is difficult to confirm based on a single mood state or a single test alone, and other similar causes, such as other medical conditions or substance use, must be differentiated.

The broad framework of management involves combining pharmacotherapy and psychotherapy tailored to the individual's situation, while monitoring changes in sleep, activity, and mood to reduce the risk of relapse.

Current treatment aims for symptom control and relapse prevention, and the combination of medication or therapy can be adjusted while monitoring effectiveness and side effects.

How to read clinical trials

In follow-up observations, changes in symptoms, functioning, sleep, medication adherence, and side effects must be continuously monitored, and effectiveness, approval, or status as standard treatment should not be judged solely by the fact of clinical trial registration or completion.

Points to verify during clinical consultations

In clinical practice, it is important to assess the onset, duration, and frequency of mood episodes; changes in sleep and activity levels; impulsive behaviors; depression and suicidal ideation; family history; current medications and side effects; and substance use.
