Hello,
As per your description here, I will definitely suggest you to take your son to a mental health professional for assessment of his mental health. Many psychiatric and mental health ailments may have similar presentation, these problems may range from poor interest in studies, bullying, alternative interests, to more severe mental health ailments like depression, psychosis/schizophrenia, addiction etc, or medical illnesses like
thyroid, anemia, visual difficulties etc. Hence a comprehensive assessment is required to get to bottom of his issues.
Hope this helps you and your son. Best wishes for your health and future..
Regards
