Can ADHD Affect Focus with OCD?

Hello Doctor,

I have been diagnosed with OCD and am currently taking fluvoxamine 200 mg, aripiprazole 2 mg, and vortioxetine 20 mg. Despite this, I’m struggling a lot with concentration and focus while studying. I often find myself daydreaming and can’t sit through more than five minutes or even complete one full topic. I spoke with my online doctor, and they recommended trying modafinil to help with focus. However, when I researched modafinil, I found some studies suggesting that it might actually worsen OCD symptoms. I’m feeling confused and worried, could you please advise which medication might be better for improving my concentration without making my OCD worse?
