As you can see, the scope of possible learning disabilities is wide. For this reason, it is so important to have testing done, and the results interpreted by a trusted professional in the field. A popular belief, in vogue 10-15 years ago, said that children with these issues were just "slow to mature". Having been through this scenario with one of my children, I want to assure you that it's not worth it to waste precious time hoping your child will simply "outgrow" his or her struggles.
If you're concerned about the possibility of learning problems in someone you love, see

common symptoms of learning problems.
There's no time like the present to address this issue.
I encourage you to learn all you can from this site, and then take action on behalf of the child or adult who is struggling.
