Bipolar Disorders Flashcards
(110 cards)
What two core dimensions define all bipolar-spectrum disorders?
Pathological oscillations in mood (elevated/irritable ↔ depressed) and in energy/activity.
What are the hallmark mood states required for a manic episode?
An abnormally and persistently elevated, expansive, or irritable mood and increased goal-directed activity or energy.
How long must manic symptoms persist to meet DSM-5-TR duration criteria?
At least one week, or of any duration if hospitalisation is necessary.
How does hypomania differ from mania in duration and severity?
Duration is a minimum of four consecutive days and the episode is not severe enough to cause marked functional impairment or require hospitalisation.
Which symptoms (besides mood elevation) count toward the manic/hypomanic symptom list?
Grandiosity, decreased need for sleep, pressured speech, flight of ideas, distractibility, increased goal-directed activity/psychomotor agitation, and risky behaviour.
How many ancillary symptoms are required in mania when mood is elevated/expansive?
At least three (or four if mood is only irritable).
What DSM-5-TR specifier captures simultaneous opposite-pole symptoms?
“With mixed features,” applied when ≥3 symptoms of the opposite pole appear during an episode.
What episode is required to diagnose Bipolar I Disorder?
One lifetime manic episode; a major depressive episode is common but not required.
What is the typical age of onset for Bipolar I Disorder?
Clustered around 18 years, with a broader range extending into the 30s.
What is the approximate lifetime prevalence of Bipolar I Disorder?
About 0.6–1 percent.
What is the sex ratio in Bipolar I Disorder?
Roughly equal (female : male ≈ 1 : 1).
What proportion of individuals with Bipolar I experience psychotic features during mania?
A majority; most patients experience hallucinations or delusions in at least one manic episode.
What is the estimated suicide mortality in Bipolar I Disorder?
Up to 15–20 percent die by suicide, and over half attempt at least once.
How heritable is Bipolar I Disorder?
Genetic contribution estimated at 60–85 percent with polygenic overlap with major depression and schizophrenia.
What percentage of people with a first manic episode will have future mood episodes?
Approximately 90 percent.
List commonly applied DSM-5-TR specifiers for Bipolar I.
Rapid cycling, melancholic features, atypical features, anxious distress, mixed features, seasonal, peripartum, psychotic features.
Name the first-line maintenance pharmacological treatments for Bipolar I.
Lithium, valproate, lamotrigine, and several atypical antipsychotics.
Which psychotherapies have proven relapse-prevention value in Bipolar I?
Psychoeducation, cognitive-behavioural therapy (CBT), and family-focused therapy.
What episodic pattern defines Bipolar II Disorder?
At least one hypomanic episode and at least one major depressive episode, with no history of mania.
How does the age of onset of Bipolar II usually compare with Bipolar I?
Onset is later, commonly in the mid-20s.
What is the lifetime prevalence of Bipolar II Disorder?
Approximately 0.8 percent.
Is Bipolar II considered clinically milder than Bipolar I?
No; time spent depressed is greater, functional impairment substantial, and suicide rates comparable.
Which pattern of episode frequency is more common in Bipolar II than in Bipolar I?
Rapid cycling (≥4 mood episodes per year).
Why must antidepressant monotherapy be used cautiously in Bipolar II?
It can precipitate hypomania and induce rapid cycling.
