<s>[INST] My son was diagnosed with ASD when he was 2 years old (4 years ago). We recently have started the discussion of a ADHD diagnosis as well, with meds used to treat (they want to use vyvanse.) What are the general thoughts on a multiple diagnosis like this? [/INST] Welcome to the ChatDoctorI understand your concerns. Child Chat Doctor.  Periodic developmental surveillance, screening, evaluation, and reevaluation throughout childhood may enhance identification of significant deficits, allowing for appropriate therapies and education to enhance later academic, behavioral, psychosocial, and adaptive functioning. As such, the prognosis of atrial septal defect is excellent. Hopefully this will help you. I would be happy to help you in any further questions. Take care </s>
