Why Bipolar and ADHD Overlap 

ADHD is a neurodevelopmental condition characterised by inattention, hyperactivity, and impulsivity. These symptoms are consistent over time and across situations. In contrast, bipolar disorder is a mood disorder defined by distinct episodes of mania/hypomania and depression. During manic phases, individuals may show hyperactivity, racing thoughts, and impulsive behaviour, features that resemble ADHD. This mood disorder overlap ADHD can easily mislead both patients and clinicians. 

Here’s how the differences play out: 

Symptom pattern:  

ADHD symptoms are chronic and relatively stable, while bipolar symptoms are episodic, appearing during mood episodes but not necessarily in between. 

Emotional changes:  

Bipolar disorder involves intense mood swings, from extreme highs to deep lows. ADHD involves emotional dysregulation but not the dramatic, sustained mood shifts seen in bipolar disorder. 

Onset and triggers:  

ADHD usually starts in childhood. Bipolar disorder often develops later, in late adolescence or adulthood, with mood episodes triggered by stress or life events. 

Because treatment approaches differ significantly, ADHD often involves stimulants, while bipolar disorder may require mood stabilisers, getting an accurate diagnosis matters. 

If you’re unsure whether your symptoms are tied to Bipolar vs ADHD, a specialist can conduct a thorough assessment to clarify the picture.
