Quick Answer
Absolutely. Adult ADHD is significantly under-diagnosed, particularly inattentive ADHD in women. Adult evaluations include a careful childhood history (DSM-5 requires symptoms before age 12, even for adult diagnoses), the ASRS or Conners adult rating scale, Qbtest, and screening for anxiety, depression, thyroid issues, and sleep disorders — all of which can mimic or worsen attention symptoms.
