Bipolar disorder does not automatically get worse with age, but it can change over time. Some research suggests that repeated, untreated mood episodes may make the condition harder to manage, while other studies find that symptoms like mania can become milder in later life. How bipolar disorder changes with age varies widely from person to person, and consistent treatment appears to play a major role.
If you or someone you love is living with bipolar disorder, it's natural to wonder what the years ahead might look like. The good news is that many of the factors that shape the long-term course are things you and your care team can work on together.
Key Takeaways
Bipolar disorder often starts early and lasts a lifetime: Symptoms usually begin in late adolescence or early adulthood, and the condition typically needs ongoing care. However, its course over the decades differs a lot between people.
The evidence on "getting worse" is mixed: Some studies link more mood episodes to a harder course, while others find mania may soften with age and that thinking skills stay fairly stable for most people.
Steady treatment may help protect the long-term course: Staying on medication, protecting sleep, avoiding alcohol and drug misuse, adding therapy, and keeping up with physical health checks are practical steps to discuss with your provider.
What Is Bipolar Disorder?
Bipolar disorder is a mental health condition that causes significant shifts in mood, energy, activity levels, and the ability to function. These shifts happen in episodes of mania or hypomania (unusually elevated or irritable mood) and depression.
There are three main types of bipolar disorder:
Bipolar I disorder: Defined by manic episodes lasting at least 7 days, or mania severe enough to need hospital care. Depressive episodes are also common.
Bipolar II disorder: A pattern of depressive episodes and hypomanic episodes, which are usually milder than full mania.
Cyclothymic disorder: Recurring hypomanic and depressive symptoms that aren't intense or long enough to count as full episodes.
Blossom's guide to bipolar 1 vs. 2 explains these differences in more depth.
How Common Is Bipolar Disorder?
Bipolar disorder affects millions of people in the U.S., and symptoms usually begin in late adolescence or early adulthood. An estimated 4.4% of U.S. adults will experience it at some point in their lives, and about 2.8% had it in the past year. Most people with bipolar disorder (82.9%) experience serious impairment.
About 25% of people with bipolar disorder in Western countries are over age 60, and experts expect that number to keep growing as the population ages.
Does Bipolar Get Worse With Age? What the Research Shows
Researchers have studied this question for decades, and the answer is not a simple yes or no. Here's what different lines of evidence suggest.
The Case for Progression
Some studies suggest bipolar disorder can become harder to manage as mood episodes add up. Research shows that more episodes can be linked to a higher risk of recurrence, longer episodes, more severe symptoms, and a lower threshold for new episodes. The same review noted that the course still varies between individuals.
The Kindling Theory and Its Limits
One well-known idea, called kindling, proposes that early mood episodes are often triggered by stress, while later episodes start more easily, with less or no trigger. However, this pattern may not always hold.
Staging Models
Some experts describe bipolar disorder in stages, moving from an at-risk period to a first episode and then to recurrences that may either improve or progress. These staging models are still being tested, and other researchers have raised questions about whether progression is the only explanation for what's observed.
Signs That Symptoms May Ease
There's also evidence that some symptoms soften with age. In a large study of more than 1,200 adults with bipolar disorder, older age was linked to less severe mania and was not linked to worse day-to-day functioning. Reviews also note that the illness may shift toward depression in later life, with manic recurrences becoming less likely.
How Bipolar Disorder Can Change in Later Life
Beyond the question of "better or worse," bipolar disorder can look and feel different as people get older. Several changes deserve attention.
Thinking and Memory
About one-third of older adults with bipolar disorder may have some cognitive impairment, such as trouble with memory, attention, or planning. However, an analysis of 10 studies following people for nearly 9 years on average found no significant difference in long-term cognitive change between people with bipolar disorder and healthy comparison groups. The authors concluded this does not suggest progressive decline for most people.
Dementia Risk
Research does link bipolar disorder with a higher risk of dementia. One meta-analysis found people with bipolar disorder had roughly three times the odds of dementia, with more mood episodes associated with higher risk. The same analysis found lithium treatment was associated with lower dementia risk, though these are observational findings and don't prove cause and effect.
Physical Health
People with bipolar disorder have higher rates of several physical health conditions and, on average, a shorter life expectancy. An analysis found all-cause death rates were about twice as high as in the general population, including higher rates of death from heart and circulatory disease.
Older adults also tend to have more medical conditions and may be more sensitive to medication side effects. That's one reason regular checkups and good coordination between your psychiatric provider and primary care team matter.
Menopause and Hormonal Shifts
For women with bipolar disorder, the menopause transition may bring more mood symptoms, especially depression. Moreover, menopause can be linked with worsening BPD symptoms.
Late-Onset Bipolar Disorder
Most people develop bipolar disorder as teens or young adults, but some have their first manic or hypomanic episode later in life. One study found about 10% of people with bipolar disorder had their first manic episode after age 45.
When manic symptoms appear for the first time in an older adult, a careful medical evaluation is important. Mania-like symptoms can sometimes be caused by:
Certain medications, including corticosteroids and some antibiotics or chemotherapy drugs
Stroke or other neurological conditions
Thyroid disease
Other medical illnesses
Factors That May Make Bipolar Disorder Harder to Manage
While no one can control every aspect of a chronic condition, research points to several factors that may worsen the course of bipolar disorder over time:
Untreated or frequent mood episodes: More episodes have been linked to a harder course in some studies.
Stopping medication: Discontinuing mood stabilizers, especially suddenly, can raise the risk of relapse.
Antidepressants used alone: Taking an antidepressant without a mood stabilizer may trigger mania or rapid cycling in some people.
Alcohol and drug use: Substance use can mimic or worsen mood symptoms.
Sleep disruption: Irregular or reduced sleep is a common trigger for mood episodes.
Ongoing stress: Major life stress can contribute to episodes for some people.
Ways to Support Long-Term Stability as You Age
Bipolar disorder usually requires ongoing treatment, but many people stay stable for long periods. These approaches may help protect your long-term course.
Consistent Medication
Mood stabilizers can help prevent future episodes, and lithium has been shown to lower suicide risk. Lithium does require extra care with age: older adults often need lower doses and closer monitoring because the body clears it more slowly. The lithium label calls for regular checks of kidney and thyroid function.
Therapy Alongside Medication
Adding structured therapy to medication may lower relapse risk. Family or couples therapy, cognitive behavioral therapy (CBT), and psychoeducation (learning about the condition and its warning signs) can each be linked to fewer relapses compared with usual care alone.
Healthy Daily Routines
Regular routines can support mood stability. Helpful habits may include:
Keeping a consistent sleep and wake schedule
Limiting alcohol and avoiding recreational drugs
Staying physically active in ways that suit your health
Tracking your mood to spot early warning signs
Keeping up with routine physical health screenings
When to Seek Medical Attention
Reach out to a mental health provider if you notice:
Signs of a new mood episode, such as sleeping much less, racing thoughts, or several weeks of low mood
New confusion, memory problems, or personality changes
Side effects from medication, such as tremor, nausea, or unusual thirst while taking lithium
Mood symptoms around menopause that feel different or harder to manage
Manic symptoms for the first time later in life
