    Study Notes

    • Bipolar and related disorders bridge the gap between schizophrenia spectrum and depressive disorders.
    • Diagnoses in this chapter include bipolar I disorder, bipolar II disorder, cyclothymic disorder, substance/medication-induced bipolar and related disorder, bipolar and related disorder due to another medical condition, other specified bipolar and related disorder, and unspecified bipolar and related disorder.
    • Bipolar I disorder is characterized by recurring mood episodes, including manic, depressive, and hypomanic, but at least one manic episode is required for the diagnosis.
    • Bipolar II disorder requires the lifetime experience of at least one major depressive episode and at least one hypomanic episode, but no history of mania.
    • Cyclothymic disorder affects adults who experience at least 2 years of both hypomanic and depressive periods without fulfilling the criteria for mania, hypomania, or major depression.
    • Substance/medication-induced bipolar and related disorder and bipolar and related disorder due to another medical condition can occur due to substance abuse, prescribed medications, or medical conditions.

    Manic Episode for Bipolar I Disorder

    • Requires a distinct period of abnormally elevated, expansive, or irritable mood and persistently increased activity or energy, lasting at least 1 week.
    • Must be present most of the day, nearly every day.
    • If the mood is irritable, at least four symptoms must be present.

    Hypomanic Episode

    • A distinct period of abnormally elevated, expansive, or irritable mood and increased activity or energy, lasting at least 4 consecutive days.
    • Must be present most of the day, nearly every day.
    • Three or more symptoms must be present, representing a noticeable change from usual behavior.
    • During antidepressant treatment, a full hypomanic episode that persists beyond the physiological effect of the treatment is sufficient evidence for a diagnosis.

    Bipolar I Disorder

    • Characterized by a clinical course of recurring mood episodes, including manic, depressive, and hypomanic.
    • At least one manic episode is required for diagnosis.
    • Major depressive episodes are common but not required.
    • Diagnostic code depends on current or most recent episode type, current severity, presence of psychotic features, and remission status.
    • Manic episodes involve euphoric, excessively cheerful, high, or "feeling on top of the world" moods.
    • May be characterized by unlimited and haphazard enthusiasm for interpersonal, sexual, or occupational interactions.
    • May involve rapid shifts in mood, referred to as lability.
    • In children, happiness, silliness, and "goofiness" may indicate abnormally elevated mood if recurrent, inappropriate to the context, and beyond expected developmental levels.
    • During a manic episode, individuals may engage in numerous overlapping new projects, often with little knowledge of the topic.
    • Increased activity or energy levels may manifest at unusual hours, like during the individual's normal sleep phase.
    • Inflated self-esteem is typically present, ranging from uncritical self-confidence to marked grandiosity, and may reach delusional proportions.
    • Decreased need for sleep is a common feature, distinct from insomnia.
    • Individuals may sleep little, if at all, or wake several hours earlier than usual, feeling rested and full of energy.
    • Both Criterion A and Criterion B symptoms may be accompanied by symptoms of the opposite (i.e., depressive) pole.
    • Thoughts race faster than speech, often leading to a flight of ideas and disorganization.
    • Distractibility prevents individuals from holding rational conversations or attending to instructions.
    • Increased goal-directed activity often includes excessive planning and participation in numerous activities.
    • Increased sexual drive, fantasies, and behavior are often present.
    • Increased sociability, psychomotor agitation, or restlessness are common.
    • Expansive mood, excessive optimism, grandiosity, and poor judgment often lead to reckless involvement in activities.
    • The diagnosis of bipolar I disorder is based on the presence of psychotic features during a manic episode, which can result in impairment.
    • Manic symptoms or syndromes attributable to the direct physiological effects of a drug of abuse, side effects of medications or treatments, or another medical condition do not count toward the diagnosis of bipolar I disorder.
    • However, a fully syndromal manic episode that arises during treatment and persists beyond the physiological effect of the inducing agent is sufficient evidence for a manic episode considered due to bipolar I disorder (Criterion D).
    • Individuals in a manic episode often do not perceive they are ill and resist treatment.
    • Mood may shift rapidly to anger or depression, and some individuals may become hostile, physically threatening, and even suicidal.
    • Depressive symptoms occur in about 35% of manic episodes, and mixed features are associated with poorer outcomes and increased suicide attempts.
    • Bipolar I disorder is associated with significant decrements in quality of life and well-being.
    • Having a first-degree relative with bipolar disorder increases the risk of diagnosis approximately 10-fold.

    Prevalence and Course of Bipolar I Disorder

    • The 12-month prevalence of DSM-5 bipolar I disorder in a nationally representative U.S.adult sample was 1.5%.
    • Higher prevalence among Native Americans and lower among African Americans, Hispanics, and Asians/Pacific Islanders.
    • The lifetime prevalence ratio in men to women is approximately 1.1:1.
    • Peak age at onset of bipolar I disorder is between 20 and 30 years, but onset occurs throughout the life cycle.
    • About half of individuals diagnosed with bipolar disorder exhibit a predominant polarity, with 31.3% with predominant mania, 21.4% with predominant depression, and 47.3% without polarity predominant.
    • The course of bipolar I disorder is highly heterogeneous, with some patterns observed across episodes.
    • Childhood adversity, including early emotional trauma, parental psychopathology, and family conflict, is a known risk factor for bipolar disorder.
    • This adversity is associated with poorer prognosis and a worse clinical picture.
    • Recent life stress and other negative life events increase depressive relapse risk.
    • Manic relapse appears to be specifically linked to goal-attainment life events.
    • Cannabis and other substance use is associated with exacerbation of manic symptoms.

    Genetics and Cultural Factors

    • Genetic processes strongly affect predisposition to bipolar disorder, with heritability estimates around 90% in some twin studies.
    • Risk of bipolar disorder in the general population is around 1%, while risk in a first-degree relative is 5%-10%.
    • Monozygotic concordance rates are significantly less than 100% (40%-70%), indicating that much risk is left unexplained by genes alone.
    • Emerging genetic findings suggest that mania- and depression-proneness are inherited separately, and bipolar disorder shares a genetic origin with schizophrenia.
    • Cultural factors may affect disorder prevalence, such as countries with reward-oriented cultural values that place significance on individual pursuit of reward have a relatively higher prevalence of bipolar disorder.

    Cultural Variations in Bipolar Disorder

    • In the United States, individuals with bipolar disorder had an earlier age at onset than those in Europe and were more likely to have a family history of psychiatric disorder.
    • Additionally, African Americans with bipolar I disorder are at higher risk of being misdiagnosed with schizophrenia.

    Sex and Gender Issues

    • Women experience rapid cycling and mixed states, have different patterns of comorbidity than men, and have higher rates of lifetime eating disorders.
    • Women with bipolar I or II disorder are more likely to experience depressive symptoms than men and have a higher lifetime risk of alcohol use disorder than do men.

    Suicide Risk

    • The lifetime risk of suicide in individuals with bipolar disorder is estimated to be 20- to 30-fold greater than in the general population.
    • An estimated 5%-6% of individuals with bipolar disorders die by suicide.
    • While suicide attempts are higher in women, lethal suicide is more common in men with bipolar disorder.
    • A past history of suicide attempt and percent days spent depressed in the past year are associated with greater risk of suicide attempts or completions.

    Comorbidity

    • Nearly half of individuals whose symptoms meet criteria for bipolar disorder have an alcohol use disorder.
    • Those with both disorders are at greater risk for suicide attempt and suicide death.

    Misdiagnosis

    • Bipolar I disorder is often misdiagnosed as unipolar depression.
    • Factors that might indicate bipolar I disorder rather than major depressive disorder include family history of bipolar disorder, onset of illness in the early 20s, numerous past episodes, presence of psychotic symptoms, and a history of lack of response to antidepressant treatment or the emergence of a manic episode during antidepressant treatment.

    Bipolar II Disorder

    • Bipolar II disorder, cyclothymic disorder, and other specified bipolar and related disorders are similar to bipolar I disorder by virtue of their including periods of hypomanic symptoms in their presentations but are differentiated from bipolar I disorder by the absence of any manic episodes.
    • A careful history of symptoms is needed to differentiate generalized anxiety disorder from bipolar disorder.
    • Similarily, symptoms of posttraumatic stress disorder need to be differentiated from bipolar disorder.
    • The diagnosis of bipolar and related disorders should be made instead of bipolar I disorder if the manic episodes are judged to be the direct physiological consequence of another medical condition.
    • Substance/medication-induced bipolar and related disorder is distinguished from bipolar I disorder by the fact that a substance or medication is judged to be etiologically related to the manic episode.
    • Schizoaffective disorder is characterized by periods in which manic and major depressive episodes are concurrent with schizophrenia symptoms and periods in which delusions or hallucinations occur for at least 2 weeks in the absence of a manic or major depressive episode.
    • The diagnosis is “bipolar I disorder, with psychotic features” if the psychotic symptoms have occurred exclusively during manic and major depressive episodes.
    • Attention-deficit/hyperactivity disorder may resemble a manic episode and have its onset by age 12.
    • Personality disorders such as borderline personality disorder may have substantial symptomatic overlap with bipolar I disorder.
    • To make a diagnosis of bipolar I disorder, symptoms of mood lability and impulsivity must represent a distinct episode of illness, or there must be a noticeable increase in these symptoms over the individual’s baseline in order to justify an additional diagnosis of bipolar I disorder.
    • Bipolar II disorder requires a diagnosis based on specific criteria, including a hypomanic episode and a major depressive episode.
    • There has never been a manic episode.

    Bipolar II Disorder

    • Characterized by at least one hypomanic episode and at least one major depressive episode

    • Higher number of lifetime episodes compared to major depressive disorder or bipolar I disorder
    • Interval between episodes tends to decrease with age
    • Diagnosis in children is challenging, especially with non-episodic irritability
    • Distinguishing late-onset bipolar II disorder in older adults is challenging
    • Hereditary component, with a family history reported in about a third of cases
    • Rapid cycling pattern is associated with a poorer prognosis
    • Functional recovery is more likely in younger individuals and with less severe depression
    • More education, fewer years of illness, and marriage are associated with better functional recovery
    • Bipolar II disorder is more common in women than men
    • Females are more likely to experience mixed features and rapid cycling
    • Childbirth can be a trigger for hypomanic episodes
    • One-third of individuals report a lifetime history of suicide attempt

    Schizoaffective Disorder

    • Characterized by periods of depressive symptoms concurrent with active-phase symptoms of schizophrenia
    • Diagnosis is made when psychotic symptoms occur exclusively during major depressive episodes
    • Characterized by a prominent and persistent disturbance in mood due to a substance or medication

    • More common in adolescence or early adulthood
    • Youth with cyclothymic disorder often experience mood symptoms before age 10
    • Individuals with cyclothymic disorder have a 15%-50% risk of developing bipolar I or II disorder

    Differential Diagnosis

    • ADHD may be misdiagnosed as bipolar II disorder, particularly in adolescents and children
    • Personality disorder diagnosis should be reserved for lifetime history, not during untreated mood episodes
    • Substance use disorders are common in individuals with bipolar II disorder, especially alcohol and cannabis use
    • Premenstrual syndrome and premenstrual dysphoric disorder can complicate the course of bipolar disorder
    • Cyclothymic symptoms can be distinguished from symptoms of other mood disorders or medical conditions

    Other Important Points

    • Bipolar II disorder is often associated with co-occurring mental disorders, most commonly anxiety disorders
    • Sociocultural factors can influence the comorbidity of bipolar II disorder
    • Rates of comorbid psychiatric disorders in children with cyclothymic disorder are similar to those in children with bipolar I or II disorder

    • Substance/Medication-Induced Bipolar and Related Disorder:

      • Symptoms must precede substance/medication use or persist beyond withdrawal/intoxication.
      • Exception: Hypomania or mania after antidepressant use or ECT persisting beyond medication effects is indicative of bipolar disorder, not substance-induced.

    • Bipolar and Related Disorder Due to Another Medical Condition:

      • A prominent and persistent period of elevated, expansive, or irritable mood and increased activity/energy due to a medical condition.
      • Onset usually occurs within 1 month of the medical condition, but exceptions exist.
      • Common medical conditions include Cushing’s disease, multiple sclerosis, stroke, and traumatic brain injuries.

    • Other Specified Bipolar and Related Disorder:

      • Used when symptoms do not meet full criteria for any specific bipolar disorder.
