Can Bipolar Disorder Begin in Later Life?

Bipolar disorder most commonly develops in early adulthood. However, some individuals are diagnosed for the first time after the age of 60. In other cases, a long-standing condition may evolve or become more complex with age.

Late-onset bipolar disorder is less common but possible. It may be linked to neurological changes, vascular conditions or medication effects. A thorough medical assessment is critical to rule out secondary causes of mood instability.

In older adults with a previous bipolar diagnosis, symptom patterns often shift over time. Manic episodes may become less intense but more frequent, while depressive episodes may dominate the clinical picture.

How Mania Appears in Seniors

 Care Home Directory

Mania in older adults often looks different from the heightened energy and impulsivity typically associated with younger patients.

Instead of extreme euphoria, seniors may display irritability, agitation or sudden changes in spending behaviour. Sleep disturbance is common, though reduced need for sleep may be less pronounced. Speech may become pressured, but cognitive slowing associated with ageing can mask this sign.

In some cases, mania may be mistaken for early dementia, particularly when accompanied by disinhibition or poor judgement.

Depression in Bipolar Disorder Later in Life

Depressive episodes in elderly individuals with bipolar disorder can be severe and prolonged. Symptoms may include persistent low mood, withdrawal, loss of interest and changes in appetite or sleep.

Because depression is more common in older adults generally, bipolar depression may be misdiagnosed as unipolar depression. This distinction is important, as treatment strategies differ.

Incorrect prescription of antidepressants without mood stabilisers can trigger manic episodes in individuals with bipolar disorder.

Key Differences Between Younger and Older Presentations

The following table outlines how bipolar disorder may appear differently in later life compared to younger adults.

Because symptoms may overlap with dementia or medication side effects, professional assessment is crucial.

Medical and Neurological Considerations

In later life, mood instability may be influenced by physical health conditions. Thyroid disorders, vitamin deficiencies, vascular disease and medication interactions can all affect mood.

Neurological conditions, including stroke or Parkinson’s disease, may also present with mood fluctuations. Comprehensive evaluation helps determine whether symptoms represent primary bipolar disorder or a secondary condition.

In England, GPs can refer individuals to mental health specialists or geriatric psychiatry services for further investigation.

Treatment and Management in the UK

Treatment of bipolar disorder in seniors typically includes mood stabilisers or antipsychotic medication, carefully adjusted to account for age-related metabolic changes.

Psychological therapies such as cognitive behavioural therapy may also support mood regulation. Monitoring physical health is particularly important, as older adults are more sensitive to medication side effects.

Structured daily routines and stable environments reduce mood fluctuation. Regular sleep patterns, social engagement and consistent medical oversight contribute to long-term stability.

In more complex cases where independent living becomes difficult due to severe mood episodes, structured support environments may be considered as part of a broader care strategy.

When to Seek Professional Help

Families should seek medical advice if an older adult exhibits sudden mood swings, impulsive behaviour, prolonged depressive episodes or alternating periods of agitation and withdrawal.

Early diagnosis prevents mismanagement and reduces the risk of hospitalisation. Bipolar disorder in later life can be effectively managed when properly identified.
