The report does suggest that Samuel exhibits ADHD-like symptoms, but there are multiple diagnostic weaknesses:
•Lack of corroboration from sources other than the patient and mother.
•Insufficient differentiation between ADHD and autism.
•No clear evidence of childhood functional impairment.
•No exploration of alternative explanations.
•Insufficient consideration of the impact of past drug use.

A more thorough differential diagnosis and broader input from other sources (e.g., past teachers, colleagues, or structured executive function testing) would strengthen the diagnostic validity.
