Waswasa and Religious OCD - Understanding the Differences

Hey, I've been thinking about the difference between Waswasa and Religious OCD. Are they basically the same thing or are they different? I know Waswasa is about those intrusive thoughts from Shaytan that make you feel anxious and doubt your worship - it's seen as a spiritual issue. But I also know OCD is more of a biological or genetic thing, a full mental disorder. Some people say it doesn't really make sense to treat OCD as just whisperings from Shaytan because that kind of downplays the disorder, especially when some recommend only Islamic remedies for something that might need therapy or even medication too. I'm a bit unsure about all this, so if anyone has some insights or knowledge on these topics, that'd be really helpful.
