Bipolar Disorder
Also known as Manic depression
This article is general health information for the selected condition. It is not a diagnosis and does not replace clinical judgement. If you have questions or need treatment advice, please consult a qualified healthcare professional.
What is bipolar disorder?
Bipolar disorder involves distinct episodes of elevated mood, called mania or hypomania, alternating with depressive episodes. It is frequently misdiagnosed as unipolar depression because people usually seek help when low rather than when high, and antidepressants given alone can destabilise mood. Asking directly about periods of elevated energy is therefore important.
Causes
- Strong genetic contribution
- Differences in neurotransmitter and circadian regulation
- Stressful life events acting as triggers
- Sleep disruption precipitating episodes
- Substance use, which can unmask or worsen episodes
Symptoms
- Elevated, expansive or irritable mood during manic episodes
- Reduced need for sleep with sustained high energy
- Rapid speech and racing thoughts
- Impulsive spending, risk taking or sexual behaviour
- Depressive episodes with low mood and loss of interest
- Marked change in function between episodes
- Psychotic symptoms in severe mania
Risk factors
- First degree relative with bipolar disorder
- Onset of mood symptoms in late teens or early twenties
- Substance misuse
- Major life stressors or shift work disrupting sleep
Diagnosis
- Detailed psychiatric history covering both poles of mood
- Collateral history from family, which is often decisive
- Mood charting over time
- Blood tests and thyroid function to exclude medical causes
- Assessment of substance use
Treatment
- Mood stabilisers such as lithium or valproate
- Atypical antipsychotic medicines
- Careful use of antidepressants, usually with a mood stabiliser
- Psychoeducation and relapse prevention planning
- Regular sleep and routine, which protects against relapse
- Crisis planning and support for family members
Self care
- Protect a regular sleep schedule, which is the strongest stabiliser
- Take mood stabilisers consistently and never stop abruptly
- Track mood, sleep and energy to spot early warning signs
- Avoid alcohol and recreational drugs
- Keep a written relapse plan agreed with family
- Build routine around meals, activity and daylight
- Attend blood monitoring appointments if on lithium
When to see a doctor
Book an appointment if:
- Early warning signs such as reduced need for sleep
- Mood changes despite taking medication
- Troublesome side effects
- Planning pregnancy, since some medicines carry risks
- Alcohol or drug use increasing
- Low mood becoming persistent
Some symptoms need emergency care rather than an appointment. See the warning signs listed above.
Prevention
- Take maintenance treatment as prescribed
- Keep sleep and daily routine regular
- Avoid stimulants and limit alcohol
- Recognise and act on personal early warning signs
- Involve family in relapse planning
- Manage stress and shift work carefully
Outlook
Bipolar disorder is long term but treatable. Consistent maintenance treatment substantially reduces relapse frequency and severity, and many people work, study and raise families without major disruption. Outcomes are best when sleep is protected, substances are avoided and treatment continues during well periods rather than being stopped once mood settles.
Common questions
How is bipolar disorder distinguished from depression?
The presence of at least one manic or hypomanic episode defines bipolar disorder. Because people rarely report elevated periods spontaneously, clinicians ask specifically about times of reduced sleep need with unusually high energy.
Is lifelong medication always necessary?
Long term treatment substantially reduces relapse for most people. Any change should be planned with a psychiatrist, since abrupt discontinuation, particularly of lithium, carries a high risk of relapse.
Why does sleep matter so much?
Sleep loss is both a common trigger for mania and an early warning sign of it. Protecting a regular sleep schedule is one of the most effective non drug relapse prevention measures.
