-
- Occurrence of one or more manic episodes which may be preceded or followed by hypomanic or major depressive episodes
- Manic episodes involve a distinct period of abnormally and persistently elevated, expansive, or irritable mood and increased activity or energy lasting at least one week (or any duration if hospitalization is necessary)
- Presents with three or more symptoms (four if mood is only irritable) such as inflated self-esteem, decreased need for sleep, talkativeness, flight of ideas, distractibility, increased goal-directed activity (work, school, social activities), and excessive involvement in risky activities (unrestrained buying sprees, sexual indiscretions)
- Mood disturbance is sufficiently severe to cause marked impairment in social or occupational functioning (inability to work or maintain relationships) or to necessitate hospitalization to prevent harm to self or others
-
- Characterized by a current or past hypomanic episode and at least one
- Hypomanic episodes involve a distinct period of abnormally and persistently elevated, expansive, or irritable mood and increased activity or energy lasting at least four consecutive days

Bipolar I vs Bipolar II
- Bipolar I Disorder
- Presence of one or more manic episodes which are more severe than hypomanic episodes
- Manic episodes cause marked impairment in functioning (inability to work, maintain relationships, or care for oneself) or require hospitalization to prevent harm to self or others
- Bipolar II Disorder
- Presence of one or more hypomanic episodes and at least one major depressive episode
- Hypomanic episodes are less severe than manic episodes and do not cause marked impairment in functioning or require hospitalization
- Absence of manic episodes differentiates Bipolar II from Bipolar I Disorder
Subtypes and specifiers of bipolar disorders

- With catatonia: Presence of catatonic symptoms (stupor, mutism, negativism, posturing, stereotyped movements) during manic or depressive episodes
- With peripartum onset: Onset of mood episode during pregnancy or within 4 weeks postpartum
- With seasonal pattern: Regular temporal relationship between mood episode onset and a particular time of year (fall or winter , spring or summer or )
Impact of bipolar disorders
- Impairment in social and occupational functioning
- Manic or hypomanic episodes may lead to impulsive or risky behaviors (unprotected sex, reckless driving), strained relationships (increased conflicts, separation or divorce), and poor judgment (overspending, unwise business decisions)
- Depressive episodes may cause withdrawal from social activities, decreased productivity at work or school, and difficulty in maintaining relationships due to low energy and motivation
- Increased risk of suicide
- Suicidal ideation and attempts are common during depressive episodes due to feelings of hopelessness, despair, and worthlessness
- Comorbidity with other mental health disorders
- (generalized anxiety disorder, panic disorder), (alcohol or drug abuse), and personality disorders (borderline personality disorder) are common comorbid conditions that complicate treatment and worsen prognosis
- Chronic course and need for long-term treatment
- Bipolar disorders are often lifelong conditions requiring ongoing medication management (, antipsychotics, antidepressants) and (cognitive-behavioral therapy, interpersonal therapy, family therapy) to prevent relapse and maintain stability
- Stigma and discrimination
- Individuals with bipolar disorders may face stigma and discrimination in personal and professional settings due to misconceptions about the illness (perceived as dangerous, unpredictable, or unable to function) leading to social isolation and reduced opportunities
- Economic burden
- Bipolar disorders are associated with high healthcare costs (frequent hospitalizations, emergency room visits, medication expenses), lost productivity (absenteeism, presenteeism, unemployment), and financial strain on individuals and families
Key Terms to Review (19)
Anxiety Disorders: Anxiety disorders are a group of mental health conditions characterized by excessive fear or worry that disrupts daily functioning. They encompass various disorders that can lead to physical symptoms like increased heart rate and sweating, and can significantly impact a person's quality of life.
Bipolar I Disorder: Bipolar I Disorder is a mental health condition characterized by at least one manic episode that lasts for at least seven days, or by manic symptoms that are so severe that immediate hospital care is needed. This disorder often involves episodes of depression and can significantly impact a person's life. The mood swings can lead to problems in work, relationships, and daily functioning, highlighting the disorder's complexity and the need for effective management.
Bipolar II Disorder: Bipolar II Disorder is a mental health condition characterized by the presence of at least one major depressive episode and at least one hypomanic episode, without ever having experienced a full manic episode. This disorder is essential to understand within the broader context of bipolar disorders, as it showcases the spectrum of mood fluctuations, where individuals experience elevated moods that are less severe than full mania but can still impact their daily functioning.
Cognitive-Behavioral Theory: Cognitive-behavioral theory is a psychological framework that emphasizes the connection between thoughts, feelings, and behaviors, suggesting that maladaptive thought patterns can lead to negative emotional states and behaviors. This theory is pivotal in understanding various psychological conditions, as it focuses on changing unhelpful thinking patterns to improve emotional well-being and behavior. By addressing cognitive distortions, individuals can learn healthier coping mechanisms and improve their overall functioning.
Depression: Depression is a common and serious mental health disorder characterized by persistent feelings of sadness, hopelessness, and a lack of interest or pleasure in activities. It can significantly impair daily functioning and is often linked to various biological, psychological, and social factors that contribute to its onset and maintenance.
DSM-5 Criteria: The DSM-5 criteria are a set of standardized guidelines used to diagnose mental disorders as defined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. These criteria provide specific symptoms and duration requirements for each disorder, helping clinicians determine the appropriate diagnosis and treatment plans for individuals experiencing psychological distress.
Ellen Frank: Ellen Frank is a prominent psychologist known for her research in the field of mood disorders, particularly in understanding and treating bipolar I and bipolar II disorders. She developed the Interpersonal and Social Rhythm Therapy (IPSRT), which emphasizes the importance of maintaining stable daily routines to manage mood fluctuations. This approach highlights how social rhythms and interpersonal relationships can significantly influence the course of these disorders.
Episode duration: Episode duration refers to the length of time that a mood episode lasts in individuals diagnosed with mood disorders, particularly those experiencing bipolar disorders. Understanding episode duration is essential in distinguishing between different types of bipolar disorders, such as Bipolar I and Bipolar II, as it helps determine the severity and impact of mood changes on a person's life.
Family Systems Theory: Family Systems Theory is a psychological framework that views the family as an emotional unit and emphasizes the interconnectedness of its members. This theory posits that individual behavior cannot be fully understood in isolation, as it is influenced by family dynamics, roles, and communication patterns. In the context of mental health disorders, understanding these familial relationships can provide insight into the development and maintenance of conditions like mood disorders.
Genetic Factors: Genetic factors refer to the inherited characteristics and variations that can influence an individual's likelihood of developing certain psychological disorders. These factors play a crucial role in understanding how mental health conditions, such as mood and personality disorders, may be passed down through families or arise due to specific genetic predispositions. By examining genetic factors, researchers can better comprehend the biological underpinnings of these disorders and their interactions with environmental influences.
Hypomania: Hypomania is a milder form of mania characterized by an elevated mood, increased energy, and heightened activity levels, but without the severe impairments or psychotic features associated with full-blown mania. This state can lead to impulsive behavior, increased goal-directed activities, and a sense of euphoria, making it an important aspect in the diagnosis and understanding of bipolar disorders, particularly Bipolar II Disorder.
Kay Redfield Jamison: Kay Redfield Jamison is a prominent clinical psychologist and author known for her work on mood disorders, particularly bipolar disorder. Her personal experience with bipolar disorder has deeply influenced her research, helping to shed light on the complexities of living with this mental illness. Jamison’s contributions to understanding bipolar I and II disorders have been vital in both clinical practice and public awareness.
Major depressive episode: A major depressive episode is a period characterized by a persistently low mood and loss of interest or pleasure in most activities, lasting for at least two weeks. This episode includes a range of cognitive and physical symptoms that significantly impair daily functioning and quality of life, often seen in individuals with mood disorders. Understanding major depressive episodes is crucial for recognizing their role in conditions like bipolar I and bipolar II disorders, where they can manifest alongside periods of elevated mood or mania.
Mania: Mania is a state of abnormally elevated mood, energy, and activity that can significantly impair judgment and functioning. It is often characterized by excessive enthusiasm, impulsivity, and a decreased need for sleep. In the context of Bipolar I and Bipolar II disorders, mania plays a crucial role as it represents the most extreme form of mood disturbance that can lead to various behavioral issues and the need for medical intervention.
Manic episode: A manic episode is a period of abnormally elevated mood and high energy that lasts at least one week, characterized by increased activity or energy levels, impulsive behavior, and grandiose thoughts. It is a core feature of bipolar disorders, specifically in the context of Bipolar I, where the presence of at least one manic episode is required for diagnosis, while in Bipolar II, the focus is more on hypomanic episodes that are less severe but still impactful.
Mood Stabilizers: Mood stabilizers are a class of medications primarily used to treat mood disorders, especially bipolar disorder, by reducing the frequency and severity of mood swings. They play a critical role in managing the manic and depressive episodes associated with these disorders, and their effects are often observed in the context of biological perspectives, bipolar disorders, biological treatments, and integrated approaches to mental health care.
Neurotransmitter imbalances: Neurotransmitter imbalances refer to the disruption in the normal levels of neurotransmitters, which are chemical messengers that transmit signals in the brain. These imbalances can significantly affect mood, cognition, and behavior, playing a crucial role in various mental health disorders. Understanding these imbalances helps in recognizing the underlying biological factors contributing to conditions like depression and bipolar disorder.
Psychotherapy: Psychotherapy is a therapeutic approach that involves structured interactions between a trained mental health professional and an individual seeking to address psychological issues or emotional difficulties. This method aims to help individuals understand their feelings, behaviors, and thoughts, leading to improved mental health and coping strategies. Various techniques and modalities, such as cognitive-behavioral therapy and interpersonal therapy, are employed depending on the specific needs of the individual, making psychotherapy adaptable for conditions like mood disorders and personality disorders.
Substance Use Disorders: Substance use disorders are a group of conditions characterized by the compulsive use of substances despite harmful consequences, leading to significant impairment or distress. These disorders can manifest through tolerance, withdrawal, and a desire to cut down on substance use, which often leads to issues in various aspects of life including relationships, work, and mental health.
