Study Notes
Medication for Bipolar Disorder
- Lithium is effective in maintenance treatment of recurrent mood disturbances in patients with bipolar disorders, with a mean relative risk of 0.65 for preventing relapses of all mood disorders.
- Lithium is effective in preventing manic relapse, but its effect in preventing depressive episodes is more equivocal.
- Predictors of a relatively poorer response to lithium maintenance treatment include rapid-cycling disorders or chronic depression, mixed affective states, alcohol and drug misuse, and mood-incongruent psychotic features.
- Valproate is increasingly used in the treatment of acute mania, with evidence of its longer-term maintenance effects showing that it is associated with a lower relapse rate compared to lithium.
Antimanic Drugs Ranked by Efficacy and Acceptability
- Haloperidol, risperidone, olanzapine, and quetiapine are ranked as the top four antimanic drugs by efficacy and acceptability.
- Lithium and aripiprazole are ranked 5th and 6th, respectively, while carbamazepine, ziprasidone, lamotrigine, and topiramate are ranked lower.
Treatment of Bipolar Depression
- Antidepressant drugs may be effective in bipolar depression, but have a number of disadvantages, including a risk of inducing mania and rapid cycling.
- Lithium may have a role in the prevention of depression in bipolar disorder, but evidence for its effectiveness in acute bipolar depression is limited.
- Atypical antipsychotic drugs such as quetiapine and lurasidone have been shown to be effective in the treatment of bipolar depression.
- Anticonvulsants such as lamotrigine and valproate may also be effective in treating bipolar depression, with lamotrigine showing benefits in a large pragmatic trial.
Psychotherapy for Bipolar Disorder
- Studies of structured psychotherapies in bipolar disorder have aimed to improve and sustain recovery, with cognitive-behavioral techniques potentially valuable in helping patients accept their illness and manage emotionally stressful situations.
- Family-based therapy has been shown to improve relationships and support for patients within their families, reducing hospitalizations and symptomatology.
- Interpersonal and social rhythm therapy has been effective in reducing relapses by maintaining regular sleep-wake routines and careful attention to sleep hygiene.
- Group psychoeducation has been shown to be beneficial in reducing relapses, with treatment adherence an important treatment goal.
Practical Management of Bipolar Disorder
- Assessment of bipolar disorder involves deciding on the diagnosis, assessing the severity of the disorder, forming an opinion about the causes, assessing the patient's social resources, and judging the effects on other people.
- Management of mania involves hospital admission, general clinical management, medication, and electroconvulsive therapy (ECT) in some cases.
- Monitoring for depressive disorder is crucial, with careful monitoring for symptoms of depressive disorder and transient but profound depressive mood change with depressive ideas.
- NICE guidance for pharmacological treatment of mania and hypomania recommends haloperidol, olanzapine, quetiapine, or risperidone as first-line treatments, with lithium or valproate added if necessary.
Continuation Treatment and Bipolar Depression
-
Continuation treatment should be continued for at least 6 months, with treatment not withdrawn until the patient has been asymptomatic for at least 8 weeks.
-
Be cautious when withdrawing lithium to avoid rebound mania.
-
Depressive episodes are common in bipolar illness and are associated with the majority of the illness burden in both bipolar I and bipolar II disorder.
-
Assessment of depression should be carried out with particular attention to suicidal thinking, which may be especially prominent after a sudden switch from mania to depression or during the course of a mixed affective state.### Treatment of Bipolar Disorder
-
Psychosocial measures can enhance treatment plans and randomized trials of approaches like psychoeducational programs and family intervention.
Psychological Approaches
- Advice on lifestyle, including regular social and sleep routines, and avoidance of illegal drugs
- Identification and avoidance of relapse triggers, such as sleep deprivation and substance misuse
- Identification of early subjective signs of relapse, like feeling driven or sleeping badly, with contingency plans
- Education about medication importance, discussion of sensitivity to side effects, and active measures to reduce them
Medication
- Antidepressant drugs should not be a first-line choice for treating bipolar depression
- Optimizing blood levels of mood stabilizers like lithium and valproate is important
- Initial treatment options for patients not taking mood stabilizers include quetiapine, olanzapine and fluoxetine, or lurasidone
- Lamotrigine can be used as a monotherapy or added to ineffective quetiapine, but slow dose escalation is required to minimize the risk of rash
- Conventional antidepressants can be used, but with caution and concomitant treatment with a mood stabilizer or an antimanic dose of an atypical antipsychotic
- ECT can be considered for patients with severe depressive symptoms requiring urgent treatment or where pharmacotherapy has been ineffective
Psychotherapy
- Structured psychotherapies like cognitive behavior therapy or interpersonal therapy can be offered to patients with bipolar depression, especially those with severe symptoms or a preference for psychotherapy
Prevention of Relapse and Recurrence
- Long-term maintenance treatment with a mood stabilizer or an atypical antipsychotic drug like quetiapine should be considered for patients with two or more episodes of illness in less than 5 years
- Valproate should not be prescribed to women of childbearing age due to the risk of neurodevelopmental defects during pregnancy
NICE Guidance on Pharmacological Treatment
- Fluoxetine combined with olanzapine or quetiapine alone can be offered to patients with moderate or severe bipolar depression not taking a mood stabilizer
- Olanzapine alone or lamotrigine alone can be considered as alternative options
- Lamotrigine can be used if there is no response to fluoxetine combined with olanzapine or quetiapine
Reluctance to Treatment
- People with bipolar disorder may be reluctant to consider long-term treatment with medication due to reasons like difficulty accepting a lifelong condition, believing they can control their mood without medication, or fearing medication will blunt their emotional life
