Seizure Disorder Hello. We are desperate searching for answers. Our 3 yr. old boy was on Singulair for 11 months when we noticed he began having atonic seizures (his head would drop forward - loss of muscle tone). He was a perfectly healthy little boy. Our intuition as parents is that Singulair is responsible for this seizure disorder he has developed. He has been off the Singulair now for 1 month and a half. His seizures have not improved at all - we feel in our hearts that he has had some neurological damage done. He had an EEG done and it shows a generalized atonic seizure disorder. He was completely healthy before. What can you tell me about your child? Any feedback will be appreciated. Thanks so much.
