My son was born with klippel-trenaunay syndrome and took neurontin for nerve pain at the age of 8. The dose was too high and he became disorientated, could not sleep and very active. Was taken off for about four months then back on at a lower dose for five months the off completely. Since then I have seen inattention and reading problems. He has always been very shy and never talked in school, until taking this drug. About a year after taking neurontin he became very active in school and was not the same child, and was diagnosed with ADHD. Could he have developed this for neurontin?
