A prior diagnosis of ADHD from childhood does not automatically block service connection for PTSD. These are distinct psychiatric diagnoses with different criteria, and the VA evaluates them separately. There is no regulation or VA policy that treats a childhood ADHD diagnosis as an automatic disqualifier for a later, unrelated PTSD claim.
To establish service connection for PTSD under 38 CFR 3.304(f), you generally need three things: a current PTSD diagnosis that meets DSM-5 criteria from a qualified clinician, credible evidence of an in-service stressor (documentation is not required, but it helps, and combat or personal-assault stressors have relaxed evidentiary standards), and a medical nexus linking the diagnosis to that stressor. If a C&P examiner or rating specialist diagnosed you with PTSD in the military and can trace it to a specific event, that diagnosis stands on its own merits.

If that happens, it's often a flawed exam rather than a settled legal bar. The presumption of soundness under 38 USC 1111 also matters here: unless ADHD was noted at your entrance exam, you are presumed to have entered service in sound psychiatric condition regarding that specific issue, and the burden falls on the VA to show clear and unmistakable evidence otherwise.
In the appealed VA decisions in VetAid's library, PTSD claims that reached the appellate stage had roughly 52% vacated or remanded, 27% affirmed as denied, and 6% reversed or granted outright — though this reflects only cases that were already appealed, not the odds of your initial claim being approved, and appealed cases are not a random sample of all claims filed.
If your PTSD claim gets denied and the decision leans on your ADHD history, request the full C&P exam report and rating decision to see exactly how the examiner reasoned it out, then consider obtaining an independent medical opinion (IMO) from a psychologist or psychiatrist who can clearly differentiate PTSD symptoms from ADHD ones and address the in-service stressor directly.
