Study Notes
Introduction to Bipolar Disorder
- Bipolar disorder is a condition where depressive episodes are prominent, but the course is marked by at least one episode of mania or hypomania.
- The term "manic depressive psychosis" was introduced by Kraepelin (1921) to describe the similarity in the longer-term clinical course of mood disturbances.
- Leonhard et al. (1962) pointed out that bipolar disorder tends to show a distinct familial clustering, differing from unipolar depression.
- The differences between unipolar depression and bipolar disorder are not great, and there may be overlap between the two groups.
Clinical Features of Mania
- Elevation of mood, increased activity, and self-important ideas are the central features of the syndrome of mania.
- Mood can be cheerful and optimistic, but can also be irritable and turn to anger.
- Mood can vary during the day, with brief episodes of depression interrupting high spirits.
- Patients who are elated may have high spirits interrupted by brief episodes of depression.
Rapid Cycling Disorders
- Some bipolar disorders occur regularly, with intervals of only days or weeks between episodes.
- Rapid cycling disorder is characterized by frequent recurrence of mood disturbance, with at least four distinct episodes a year.
- The disorder is more common in women, and concomitant hypothyroidism is common.
- Antidepressant drug treatment can trigger rapid cycling.
- The lifetime risk of rapid cycling in bipolar populations is around 15-30%.
Cyclothymia
- Cyclothymia disorder refers to a persistent instability of mood, with numerous periods of mild elation or mild depression.
- It is seen as a milder variant of bipolar disorder.
- Episodes of more severe mood disorder can supervene in the course of the disorder.
Depression in Bipolar Disorder
- Depressive episodes are common in bipolar disorder, and most patients present initially with an episode of major depression.
- Family history of bipolar disorder can provide a clue to predict which patients will eventually develop bipolar illness.
- The presence of any hypomanic or mixed symptomatology at initial presentation has some predictive value.
- Psychomotor retardation, early morning awakening, morning worsening, and psychotic features are more common in patients with bipolar disorder.
Epidemiology of Bipolar and Unipolar Disorder
- Lifetime risk of bipolar disorder is around 1%, and of unipolar disorder is around 15%.
- Sex ratio is 1:1 for bipolar disorder and 1:2 for unipolar disorder.
- First-degree relatives of patients with bipolar disorder have a higher lifetime risk of bipolar disorder.
- Average age of onset is 18 years for bipolar disorder and 27 years for unipolar disorder.
- Patients with recurrence are around 90% for bipolar disorder and 80% for unipolar disorder.
Appearance and Behavior
- Patients' appearance often reflects their prevailing mood, with bright and ill-assorted clothing in manic states.
- Manic patients are overactive, and may start many activities but leave them unfinished.
- Appetite is increased, and sexual desires are increased, leading to uninhibited and out-of-character behavior.
- Sleep is often reduced, and patients wake early, feeling lively and energetic.
Speech and Thought
- Speech is rapid and copious, with thoughts crowding into the mind in quick succession.
- Flight of ideas is common, with rapid changes in the flow of thought.
- Expansive ideas are common, with patients believing their ideas are original and their opinions important.
- Grandiose delusions and delusions of persecution can occur.
Perceptual Disturbances
- Hallucinations occur, usually consistent with the mood, taking the form of voices speaking to the patient about their special powers.
Other Features
- Insight is invariably impaired in more severe manic states.
- Patients see no reason why their grandiose plans should be restrained or their extravagant expenditure curtailed.
- Most patients can exert some control over their symptoms for a short time, and many do so when the question of treatment is being assessed.
Clinical Features of a Manic Episode in ICD-10
- Mood is elevated out of keeping with the individual's circumstances, varying from carefree joviality to almost uncontrollable excitement.
- Increased energy results in overactivity, pressure of speech, and a decreased need for sleep.
- Social inhibitions are lost, attention cannot be sustained, and there is often marked distractibility.
- Self-esteem is inflated, and grandiose and optimistic ideas are freely expressed.
- Perceptual disorders may occur, such as vivid appreciation of colors.
Criteria for Manic Episode in ICD-10 and DSM-5
- ICD-10 requires a diagnosis of manic episode to be made if the episode lasts for at least one week and is severe enough to disrupt ordinary work and social activities.
- DSM-5 requires a diagnosis of manic episode if the episode lasts for at least one week, and at least three manic symptoms are present.
- Both ICD-10 and DSM-5 note that some patients with mania present with psychotic symptoms, in which case the clinical picture is typically more severe.
