Our 6 year old ds has suddenly developed symptomsof adhd. Also sudden change in vision],fine motor skills and speech pattern. Scheduled to see neurologist but searching for answer in meantime. Came across info on PANDA. he had his tonsils removed in august because of repeated step. He always acted crazy whenever he had step, pediatrician said it was probably because of the additives on antibiotics. Just wondering if it is a possibIlity. Thanks!
