My Grandson paces and chews his fingernails until they bleed. Most of the time he seems like he’s in his own world. Could this be a sign of autism?
Autism, or autism spectrum disorder, refers to a range of conditions characterized by challenges with social skills, repetitive behaviors, speech and nonverbal communication, as well as by unique strengths and differences. We now know that there is not one autism but many types, caused by different combinations of genetic and environmental influences.
I do not know if it is autism with this limited information but depending on his age I truly believe that you should look to have your grandson evaluated further to determine if the habits that you are noticing are associated with an form of autism. You could look to a developmental pediatrician or if he is in school talk to his teacher to see if the school has a counsellor that could help with an evaluation.
