neuropsychological testing

Has anyone here done comprehensive neuropsychological testing? If so, did it confirm your OCD diagnosis? **Did anyone “lose” their OCD diagnosis/have it questioned through this process?** I ask because I (24F) was officially diagnosed with OCD last summer by a psychiatric nurse practitioner, whom I only met virtually. Several therapists had brought up the possibility with me over the past several years, but I had never been formally diagnosed. Once I received the diagnosis last summer, it provided a coherent, precise explanation for many thought patterns and experiences! It felt like a revelatory framework that explained many confusing and persistent issues in my life. I started ICBT and switched meds, which yielded major positive results. However, that psych provider also suggested a diagnosis of obsessive compulsive personality disorder (OCPD), which led me and my family to desire a second opinion. OCPD’s name resembles OCD, but the conditions differ quite starkly due to OCPD arising from a personality-level, ego-syntonic need for control vs. OCD arising from trigger-based, distressing, ego-dystonic thoughts. Also, I resonated significantly less with OCPD than OCD. Also, my therapist and I suspect possible ADHD and/or autism. Hence, I pursued full neuropsychological testing. At my intake yesterday, the doctor explained that she intends to actively assess/test for OCD along with autism and ADHD. The re-assessment of OCD surprised me and sent me into a worried state. I understand that neuropsychological testing requires thoroughness to specify and differentiate diagnoses. At the same time, the re-assessment of OCD raises the stakes around this testing because it opens the possibility of finding this diagnosis, which I embraced as profoundly explanatory and a catalyst to genuine relief via therapy and meds, to be false. While I believe that I meet criteria and know how to articulate my symptoms clearly, the stories of neuropsychologists attributing symptoms to other mental health disorders, particularly in women, ring loudly in the back of my mind. I also had an assessment for autism that also considered OCD at age 17, which found adequate evidence for neither condition. It attributed all symptoms to my anorexia, which I unfortunately still struggle with. Granted, my insight has grown tremendously since then and will certainly benefit the accuracy of this assessment. However, that past experience, the report from which this doctor will review, raises my concern about the potential attribution of all traits to my eating disorder, anxiety, and depression with not only no ADHD/autism but also no real OCD. So I decided to reach out here to ask if anyone sought out neuropsychological testing and, if so, how they inquired into and determined the validity of an OCD diagnosis. Thanks for any light you can shed on the process!
