I based this off of the effects of a clinical trial for a new form of epidural in the 1990s. This drug isn't used now, and was found to cause perinatal hypoxia in some cases. Hypoxia can cause ADD/ADHD, dyslexia, NvLD, fine motor problems, etc., but rarely reduces intelligence. Therefore, the effects can have permanent emotional implications.
It isn't limited to this interpretation, however. It should be fluid as well.
