First, breathe. He's still the same little boy. The diagnostic process is just to help him, not to say there's anything wrong with him or with your parenting.

It's a good idea to do genetic testing, just to rule anything out. You said he had abnormalities on his CT scan, has he had an MRI? Sometimes those can catch more of what's going on in the brain. Also, testing can help find a specific condition that he might have, and then if it's a more common condition, there's help from groups supporting people with that, even without insurance. If you're in the United States, your state might have some sort of insurance for children.

Even if he has a few challenges, he's still your son, and he still has a lot of hope for the future!
