Can you give more details? My daughter had one at 4 months and I think there might be parallels.
Honestly, jim, I would suspect the REASON he got a spinal tap in the first place, instead of the spinal tap itself. It sounds like your son had a serious illness that warranted a spinal tap.
I think looking in that direction - toward the disease or virus or bacteria - instead of the spinal tap procedure - might be helpful.
On the other hand a lot of boys have ADHD who have never had a spinal tap or any serious disease that would warrant a spinal tap.
My son is 6 and he gets a spinaltap every 3 months.....i have not noticed nore have his teacher any add,or adhd behavior.....in 2006 he was dinosed with cancer and had 13 spinaltaps in that year,,so its been almost 3 years of constent spinal taps at first every week... then every month..now every 3 months until he is done with his cemo...On the other hand my 7 yrold dose show add,adhd behavior..but our dr wont test until he is 9......so good luck and i hope this helps a little...
