Q: “How can diagnosing clinicians differentiate between rejection sensitive dysphoria (RSD) – the emotional highs and lows associated with ADHD – and the similar ups and downs of bipolar disorder?”A: Bipolar disorder and attention deficit hyperactivity hyperactivity disorder (ADHD or ADD) share 14 features in common, so even a well-trained clinician could easily misdiagnose ADHD as bipolar, vice versa, or miss that both disorders are present.
Two studies, the STAR*D program and the STEP-BD program, both found a tremendous overlap between the disorders; if you have bipolar disorder, you have a 40% chance of having ADHD as well.
So, the question is: Could it be ADHD, bipolar disorder, or both?Unlike ADHD, bipolar is a classic mood disorder that has a life of its own separate from the events of a person’s life, outside of the person’s conscious will and control.
Bipolar moods aren’t necessarily triggered by something; they just come and they stay. Usually, the onset is very gradual over a period of weeks to months.
