Mixed muscle tone can be indicative of what is called Dyskinetic CP. Learning disabilities are associated with the majority of patients presenting, with the degree of disability increasing with their degree of physical impairment. That said, it's the majority, not a given. Also associated with Dyskinetic CP is seizure disorder. Given that your son has a seizure disorder without an otherwise known cause AND the mixed muscle tone, Dyskinetic CP would be what a doctor/medical professional is leaning toward which would lead them to the intellectual disabilities part of things. That said, like Mandy mentioned-saying "never" is absolutely inappropriate. Letting you know of probabilities and highly unlikelies is one thing but absolutes in a 5 month old that hasn't been given a definitive diagnosis? That wouldn't sit well with me. I would make sure and address that, but I would also follow the diagnostics advice because in CP early intervetions are so important. The benefits of those interventions usually will far exceed the risks of sedation/MRI/etc.
