ADHD and Bipolar Disorder have a fair amount in common. For example, both conditions can cause someone to feel like they have racing thoughts. Not surprisingly, you can have both conditions at the same time.
In fact, it happens quite frequently:
One study estimated that around 12-40% of people with ADHD might also have Bipolar Disorder. Similarly, around 9-35% of those with Bipolar Disorder may also have ADHD.
This overlap isn’t just with Bipolar Disorder.
Individuals with ADHD frequently experience additional mental health conditions. One study estimated that up to 80% of people with ADHD will experience at least one other mental health condition.
Studies have also found higher rates of anxiety and depression in those with ADHD.
Having ADHD and bipolar disorder together also affects the symptoms we experience. One study found that those with ADHD and Bipolar Disorder were more likely to experience episodes of mania.
Essentially, having both conditions together makes Bipolar Disorder more severe.
As shown in summary below, ADHD also affects when we start experiencing the symptoms of Bipolar Disorder, as ADHD is associated with earlier episodes of mania.
Having ADHD and Bipolar Disorder together can make it harder to treat ADHD symptoms.
One of the warnings for Adderall and Ritalin highlights the risk of prescribing these medications to individuals with Bipolar Disorder.
These medications can potentially cause manic episodes for those with Bipolar Disorder.
This risk is significant enough that the FDA recommends that individuals with ADHD and depressive symptoms should be screened for Bipolar Disorder before taking stimulant medications.
This doesn’t necessarily mean that ADHD symptoms shouldn’t be treated if someone has bipolar disorder. Stimulants can be a safe treatment option if the underlying symptoms of bipolar disorder are treated first.
In a scientific review of the data on ADHD treatments and Bipolar Disorder, scientists concluded that stimulants and Strattera could be used safely once a patient with bipolar disorder is treated for their symptoms.
