Yes, Bipolar mood swings ADHD can create confusion, especially when symptoms overlap. During manic or hypomanic episodes, people with bipolar disorder may appear impulsive, distracted, and disorganised, behaviours that resemble ADHD. However, the root causes and patterns behind these symptoms differ significantly.

Understanding the Overlap 

In inattention bipolar disorder, focus problems are typically episodic. A person may have bursts of energy, racing thoughts, and an inability to focus during a manic phase, followed by deep fatigue and disengagement during depression. In contrast, ADHD-related inattention is more chronic and consistent across time and situations. 

Here’s how ADHD-like symptoms might show up in bipolar disorder: 

During mania:  

The person may start many projects without finishing them, struggle to stay on topic, and act impulsively. 

During depression:  

They may experience slowed thinking, low energy, and difficulty concentrating, symptoms also found in ADHD. 

Between episodes:  

Attention may return to baseline, unlike in ADHD where issues tend to persist. 

This overlap makes accurate diagnosis tricky, but vital. Treating bipolar disorder with ADHD medications (like stimulants) without mood stabilisation can increase the risk of triggering mania. 

If you’re experiencing Bipolar mood swings ADHD similarities, it’s important to consult a clinician who understands both conditions and can offer a clear, tailored diagnosis.
