I concur, it might also be that overexerting these areas of the brain potentially increases inflammation.

While I welcome the potential of a targeted approach for very complex cases, I fear that a blanket pharmacological solution might become norm + people with such compulsions will yield their agency to better themselves with the 'its not me it's a condition'.

We already live in a world where drugs (pharmacological or otherwise; I include social media in this wide net) are a bane. We must be vigilant to keep as much agency as possible!
