Bipolar disorder is often thought of as a condition that affects younger adults—but that picture is incomplete. As our population ages, Older Age Bipolar Disorder (OABD) is becoming increasingly common and deserves focused attention from patients, families, and healthcare providers alike.
Older Age Bipolar Disorder is typically defined as bipolar disorder in adults age 60 and over, and it presents with unique clinical, medical, and treatment considerations that differ from bipolar disorder earlier in life.
How Common Is Bipolar Disorder in Older Adults?
Epidemiological studies suggest that 0.5–1% of older adults live with bipolar disorder, compared to about 1.4% of adults ages 18–44. While the prevalence appears lower, this is likely an underestimation, as bipolar disorder is often missed or misdiagnosed in older populations.
Currently, adults over 60 make up approximately 25% of the bipolar population, and projections suggest this number may rise to 50% by 2030 due to increased life expectancy and population aging.
An interesting demographic note: nearly 70% of individuals with OABD are women, largely attributed to longer female life expectancy.
When Does Bipolar Disorder Begin?
Most individuals with bipolar disorder experience symptom onset between ages 20 and 40, often starting with depression or anxiety in adolescence. However, a smaller group develops bipolar disorder later in life, known as late-onset bipolar disorder.
Late-onset cases often look different clinically and require careful assessment to rule out medical or neurological causes.
How Bipolar Disorder Looks Different in Older Adults
Bipolar disorder in older adults often presents with:
- Irritability and agitation
- Confusion or cognitive changes
- Depression-predominant episodes
- Mixed mood features
As people age, episodes may become more frequent or severe, yet paradoxically:
- Suicide attempts are less common
- Psychotic symptoms occur less frequently
These differences can make diagnosis more challenging.

The Risk of Misdiagnosis
One of the biggest challenges in older adults is that bipolar symptoms can overlap with other conditions, such as:
- Dementia or Alzheimer’s disease
- Stroke
- Delirium or medication side effects
Symptoms like agitation, memory problems, or confusion may lead to bipolar disorder being mistaken for a neurocognitive disorder. Additionally, secondary mania may occur later in life due to medical conditions such as infections or neurological illnesses, making a thorough medical evaluation essential.
Medical Complexity and Cognitive Health
Older adults with bipolar disorder often manage three to four chronic medical conditions, commonly including:
- Cardiovascular disease
- Diabetes
- Metabolic syndrome
These comorbidities contribute to:
- Polypharmacy (multiple medications)
- Increased risk of medication interactions
- A reduced average life expectancy of about 10 years
Cognitive impairment is also common, affecting 40–50% of individuals with OABD, particularly in areas such as:
- Memory
- Attention
- Executive functioning
- Processing speed
Importantly, bipolar disorder in older age is considered a risk factor for developing dementia, reinforcing the need for early identification and ongoing monitoring.
Comprehensive Assessment: What’s Important?
A thorough evaluation is critical and should include:
- Medical workup (labs, physical exam, possible neuroimaging)
- Medication review, especially for drugs that may induce mania
- Comprehensive psychiatric assessment
- Collateral information from family or caregivers (with consent)
- Mood pattern evaluation (irritable, mixed, or depression-dominant)
- Suicide risk assessment
- Cognitive screening
Helpful tools may include:
- Mood Disorder Questionnaire (MDQ)
- Geriatric Depression Scale
- Geriatric Anxiety Scale
Treatment and Management in Older Adults
There are currently no FDA-approved medications specifically for bipolar disorder in older adults, so treatment follows principles of geriatric psychiatry:
“Start Low and Go Slow”
Medication sensitivity increases with age, making cautious dosing essential.
Common medication considerations include:
- Lithium (often first-line for maintenance), with close monitoring of kidney and thyroid function
- Lower target blood levels are recommended (approximately 4–0.8)
- Mood stabilizers such as valproic acid and lamotrigine
- Second-generation antipsychotics like quetiapine or lurasidone, used carefully
The Role of Therapy and Psychosocial Support
Medication alone is rarely enough. Evidence-based therapies are especially valuable in older adults, including:
- Cognitive Behavioral Therapy (CBT)
- Interpersonal and Social Rhythm Therapy (IPSRT), which focuses on stabilizing daily routines such as sleep, meals, and social activity
- Family-Focused Therapy, which supports caregivers and strengthens communication
Routine, consistency, and social connection are vital protective factors for seniors with bipolar disorder.
Why This Matters
Older Age Bipolar Disorder is a complex and growing clinical population with overlapping medical, cognitive, and psychiatric needs. Compared to younger individuals with bipolar disorder, older adults benefit most from an integrated care model that addresses both mental and physical health.
As we look toward the future—where half of all individuals with bipolar disorder may be over age 60—increasing awareness, improving diagnostic accuracy, and providing age-appropriate treatment will be essential.
At Therapy Treatment Team, we believe that thoughtful, collaborative care can make a meaningful difference at every stage of life.
