Happy to have a crack at answering this. I have been diagnosed with both ADHD and Bipolar II, and my psychiatrist (who happens to be a world renowned expert in ADHD) tells me that the two disorders are 10% co-morbid.
ADHD can present in lots of different ways, and it’s not always hyperactive - I can be distractibility, trouble concentrating and yes a bit restless. Both conditions involve impulsivity, irritability, hyperactivity, emotional dysregulation, sleep problems, a racing brain, and problems with maintaining attention.
Bipolar episodes are more clearly marked by elevated mood states or hypo-manias in my case. It’s a more persistent state of mind. I tend to lose the flavour for life, my sleep patterns permanently change (I’m awake most of the night and don’t need sleep, or I’ll sleep 18 hours a day), I’ll become more goal oriented and start working 10-12 hours a day and don’t feel that I can stop or I will lose momentum.
Low energy is another give away, as my kind of ADHD does have me functioning with quiet a high motor.
Sever changes in my mood, from all systems firing to crashing and can barely leave the house. Self destructive behaviour, and delusional thoughts (last episode I hated everyone, couldn’t trust anyone, became paranoid and believed everyone was working against me).
These more severe changes in my mood are what gave away the bipolar diagnosis. Also, I reacted poorly to the ADHD medication and SSRI antidepressants, which cause a rapid cycling of my mood states, and a mixed episode which was basically a “depressed mania”, which was awful.
If you have extra questions, I’m very happy to answer them 🙂 and hope this helps!
