For adults with ADHD and possible autism, how do you prioritise assessments?

When an adult presents with ADHD symptoms plus possible autism traits, the smartest way to prioritize assessments is to look at what’s impairing function right now, what’s developmentally relevant, and what will actually change the treatment plan.severe executive dysfunction → prioritize ADHD shutdowns, meltdowns, sensory overload → prioritize autism burnout, depression, or anxiety overshadowing everything → stabilize mood first You always start where the person is struggling the most, not with the most “interesting” diagnostic question. ADHD is usually assessed first if the goal is to improve day‑to‑day functioning quicklyAutism is prioritized first when the core issue is identity, sensory processing, or social cognition When both are present, the order depends on the pattern of symptoms; Prioritize ADHD assessment when:symptoms fluctuate with structure, interest, or stimulation executive dysfunction is the main barrier the person says “I can do it sometimes, but not consistently” emotional dysregulation looks reactive, not baseline Prioritize autism assessment when:symptoms are lifelong, stable, and not context‑dependent sensory issues dominate social differences are present even in low‑demand settings masking is causing exhaustion or burnout Consider what the assessment will changeThis is the most practical question. ADHD assessment changes:medication options executive‑function strategies workplace/school accommodations task‑activation supports Autism assessment changes:sensory accommodations communication supports identity understanding expectations around social functioning burnout prevention If one of these domains is urgently needed, that assessment goes first. If trauma, anxiety, or depression are muddying the picture, stabilize those firstNot because they “cause” ADHD or autism — but because they can mimic or amplify symptoms.
