If so, how has your OCD been lately?My answer: I've been struggling a lot with OCD recently, particularly after the birth of my first child. On the bright side, I've recently started tweeting about OCD as a coping mechanism and have found that to be quite cathartic.
Exposure and response prevention (https://iocdf.org/about-ocd/ocd-treatment/erp), a form of CBT, has helped me a lot. I'm less familiar with other interventions.
In terms of causes, OCD is substantially heritable. I think this sentence from a recent review paper (https://pubmed.ncbi.nlm.nih.gov/34030745) summarizes what's known better than I can: "Despite significant efforts to uncover the genetic basis of OCD, the mechanistic understanding of how genetic and environmental risk factors interact and converge at the molecular level to result in OCD's heterogeneous phenotype is still mostly unknown."
