i am not sure what my neighbor's 5 year old son has but it worries me. when he was smaller he was a typical kid and born free of illness, now he blinks rapid and often (not a normal blink), he makes a clicking noise with his throat (not like he's trying to clear it ), he is also forgetting how to count to 10, the difference between english and spanish and he'll get on his hands and knees kick his legs back then come to a kneeling position and then start rocking he'll do that like three times. He's seen a neurologist which have done studies to his brain waves they dont see anything real abnormal but a few stronger brain waves in some areas the doctor said his issues will go away eventually. can you shed some light to what this might be?
