Continue active phase of psychological treatment, e.g., CBT and IPT
–Plan how to cope with future triggers to depressed mood
–Develop a plan for how to respond if symptoms re-emerge
Treatments specifically for relapse:
–Wellbeing cognitive therapy
–Preventive cognitive therapy
–Mindfulness-based cognitive therapy
When did mania and depression begin to be seen as a single entity?
During the late nineteenth century
How is Bipolar Disorder diagnosed?
Bipolar disorders embrace a spectrum of disorders including bipolar I, bipolar II and cyclothymic disorder
These three disorders all share symptoms of pathologically elevated mood
These elevated mood states are referred to as ‘manic’ and ‘hypomanic episodes’
What are manic and hypomanic episodes?
A manic episode is defined by the DSM-5as elevated, expansive or irritable mood with increased goal-directed activity or energy for at least 1 week, plus at least three of the following: Inflated self esteem or grandiosity, sleep disturbance, decreased need for sleep, pressure of speech, flight of ideas, distractibility, heightened activity, risk taking
A hypomanic episode only requires symptoms to be present for at least 4 days, and symptoms tend to be less severe
What are the different types of Bipolar Disorder?
Bipolar I disorder:
–Presence of one or more manic episodes
–Major depression may be present but not required for the diagnosis
Bipolar II disorder:
–At least one episode of major depression
–At least one period of hypomania
–Must not have had a manic episode
Cyclothymic disorder:
–Symptoms are less severe but more chronic than bipolar I or II
–Numerous periods of elevated and depressed mood, but not severe enough to meet criteria for hypomanic, manic or major depressive episode
What are key problems with underdiagnosis and overdiagnosis of bipolar disorder?
Patients with bipolar disorder may be misdiagnosed as having schizophrenia (men) or major depressive disorder (women):
–Misdiagnosis as schizophrenia may be because of similarities between psychotic features of acute mania and schizophrenia (e.g., delusions and hallucinations)
–Misdiagnosis as major depressive disorder may be because past episodes of hypomania or mania are not adequately explored by the clinician
Brief periods of elevated mood may be wrongly diagnosed as hypomania
–Common for those with borderline personality disorder
–Could mean inappropriate use of mood-stabilising medications
What is the lifetime and 12 month prevalence of Bipolar Disorder?
Lifetime prevalence of 1.3 per cent
12-month prevalence of 0.9 per cent
What are key problems are associated with Bipolar Disorder?
Anxiety disorders
Substance misuse:
Reported in 39 per cent of people with bipolar disorder
Social and economic costs:
Those with bipolar disorder are almost five times more likely to have disrupted relationships
Suicide: Suicide rate is nearly 15 times that of the general population
What is the relationship between Bipolar Disorder and Creativity?
Research findings are inconsistent but many people with bipolar disorder identify as creative
Subjective value of creativity has implications for treatment of bipolar disorder, e.g., addressing concerns that bipolar medication might blunt creativity
Shared vulnerability model – Vulnerability to pathology and creativity share factors such as cognitive disinhibition, an attentional bias towards novel stimuli, and neural hyperconnectivity
What do twin studies suggest the heritability rate of Bipolar Disorder disorder is?
85 per cent
