Can a bout of gastroenteritis cause a regression?
Any infectious disease can temporarily cause behaviors to worsen. This is typically not a regression but an amplification of aggression, anxiety, or worsening of focus. There is typically no loss of any prior developmental gains; you just might not see the prior gains because these other issues can be so overwhelming for the child.nWithin a few weeks, after the infectious process resolves, the child will recover from the inflammatory injury and return back to their most recent neurological baseline.
