Lecture 9, Bipolar Disorder Flashcards
How do we know if a disorder is ‘normal’?
There are subjective and objective ways to determine if the symptoms of a disorder are normal. Subjective ways include personal experiences or opinions of friends, while objective ways involve checking if the symptoms fall within a normal distribution, if people without the disorder experience them, if a person can function effectively despite experiencing the symptoms, and if they can be explained by normal cognitive functioning.
Study on Self-reported History of Hypomanic Symptoms in a Student Population
Udachina and Mansell (2007) conducted a study on first-year psychology undergraduate students using the Mood Disorder Questionnaire. The questionnaire is a self-report inventory that screens for a lifetime of (hypo)manic experiences. The study sample consisted of 167 students.
Characterisations of Mood Episodes in Bipolar Disorder
Mood episodes in bipolar disorder are characterized by an unequivocal change in functioning that is uncharacteristic of the person when not symptomatic. The symptoms must cause clinically significant distress or impairment in social, occupational, or other important areas of functioning. Additionally, the disturbance in mood and change in functioning is observable by others.
Symptoms of Major Depression
Symptoms of major depression include depressed mood most of the day, nearly every day for at least two weeks, along with markedly diminished interest or pleasure in all, or almost all, activities. At least three of the following symptoms must also be present: significant change in appetite or weight, insomnia or hypersomnia, psychomotor agitation or retardation, fatigue or loss of energy, feelings of worthlessness and/or inappropriate guilt, diminished ability to think or concentrate, and recurrent thoughts of death, suicidal ideation, suicide attempt, or a specific plan to commit suicide.
Symptoms of Mania and Hypomania
Mania and hypomania are characterized by an abnormally and persistently elevated, expansive or irritable mood, along with abnormally and persistently increased activity or energy. In mania, these symptoms must last for at least one week, while in hypomania, they must last for at least four days. Additionally, at least three of the following symptoms must be present: inflated self-esteem/grandiosity, decreased need of sleep, more talkative than usual/pressure of speech, flight of ideas/thoughts racing, distractibility, increased goal-directed activity, and excessive involvement in pleasurable activities that may have high potential for painful consequences. Mania must lead to marked impairment in social or occupational functioning, hospitalization or psychosis.
Predictors of Relapse in Bipolar Disorder:
-> Stressful interpersonal life events (Hammen et al., 1992)
-> High ‘Expressed Emotion’ (hostility, overprotectiveness, criticism) in family members (Miklowitz et al., 1988)
-> Disrupted social rhythm events (Malkoff-Schwartz et al., 1998) including sleep changes
-> Goal-attainment events (Johnson et al., 2000) *manic symptoms and not depression
Cyclothymia:
For at least 2 years:
-> Numerous periods of hypomanic symptoms not meeting threshold for hypomanic episodes
-> Numerous periods of depressed mood / loss of interest that do not meet depression
-> The symptoms cause clinically significant distress or impairment in: social, occupational or other important areas of functioning
Other Specified Bipolar Disorder:
Different types: There is a lot of co-morbidity between mood disorders, trauma disorders and anxiety disorders
Short-duration hypomanic like episodes (2-3 days) and major depressive episodes
Hypomanic-like episodes with insufficient symptoms and major depressive episodes
Hypomanic episodes without prior major depressive episode(s)
Short-duration cyclothymia
Short-duration manic-like episodes
Unable to determined whether bipolar or related disorder is primary.

Bipolar At Risk (BAR) Criteria:
Early detection of BD has focused on familial risk and identification of state-trait factors.
Standardised BAR criteria developed by Bechdolf & colleagues (2010) – youth (15-25) experiencing short duration high mood; short duration high and low mood & first degree relative with BD plus low mood.
BAR criteria has predictive validity, can be reliably assessed in an NHS context, and holds clinical utility.
What do we know about BD? Importance of early identification:
BD affects 1-3% of the population
Average duration of untreated illness (DUI) is 6-10 years, or longer for onset in adolescence
Longer DUI is associated with more mood episodes and higher risks of suicide
Economic impact of BD in the UK is projected to be £8.2 million by 2026
Biological & Psychological Underpinnings of BD:
High heritability, separate heritability of mania & depression, and genes for mania may involve reward pathways, i.e., dopamine function are all biological factors that lead or contribute to the onset of BD
‘Resistance’ to Bipolar Disorder (Seal et al., 2008):
12 individuals aged 30+, most with a history of diagnosable hypomanic episodes, that never sought treatment, no history of clinical depression and no diagnosis of BD.
Key findings:=
High levels of functioning
Lower levels of catastrophizing about changes in internal states
Reported ‘awareness’ of behavior and social impact when feeling high
NICE Guidelines for Bipolar Disorder (BD) Treatment in Primary Care
Review treatment and care, including medication (e.g., antidepressant medication)
Offer choice of an evidence-based psychological intervention developed for BD (Cognitive Behavioural Therapy, Interpersonal Therapy, or Behavioural Couples Therapy)
NICE Guidelines for Bipolar Disorder (BD) Treatment in Secondary Care
Refer urgently if there is deterioration in depressive symptoms, signs of hypomania, or mania
Consider stopping antidepressant medication if mania or hypomania develops and offer an antipsychotic
Offer evidence-based psychological intervention
Treatments for Bipolar Disorder (BD)
Medication: mood stabilisers (e.g., lithium), antidepressants, and antipsychotics
High relapse rates despite adequate medication (Solomon et al., 1995)
Psychological treatments: relapse prevention, psychoeducation, Family Focused Therapy, and Cognitive Behavioural Therapy
