Yes, it is possible for a non-autistic individual to have OCD (Obsessive-Compulsive Disorder), ADHD (Attention-Deficit/Hyperactivity Disorder), Tourette's Syndrome, Selective Mutism, ARFID (Avoidant/Restrictive Food Intake Disorder), NVLD (Non-Verbal Learning Disorder), Dyspraxia, and Prosopagnosia. These are all separate neurological and psychological conditions that can affect individuals independently of each other.
As for being asexual and aromantic, one's sexual orientation and romantic orientation are separate aspects of their identity, and it is entirely possible for someone to identify as both asexual (experiencing little or no sexual attraction) and aromantic (experiencing little or no romantic attraction). These orientations are independent of any neurological or psychological conditions.
Regarding being a sociopath, it's important to clarify that the term "sociopath" is not a clinical diagnosis in the current mental health classification systems. Instead, it is often used colloquially to describe individuals who exhibit certain behavioral traits associated with Antisocial Personality Disorder (ASPD).
If someone experiences ASPD or sociopathic traits, it is still possible for them to have other neurological or psychological conditions such as those listed above. Mental health conditions and orientations are diverse and can coexist in different combinations within individuals.
If you are concerned about your own mental health or well-being or suspect that you might have specific conditions or orientations, I encourage you to reach out to a qualified mental health professional for a comprehensive evaluation and support. They can provide a proper assessment and guidance tailored to your unique situation. Self-diagnosis can be misleading and is best avoided. Seek professional help to gain a better understanding of your experiences and to explore potential treatment options if needed.
