Attention deficit hyperactivity disorder (ADHD) may persist into old age with prevalence rates up to 4.4%. We present a case report of an 80-year old man with ADHD complicated by personality pathology and a mild impairment in some executive functions. We illustrate that ADHD in older adults may be misdiagnosed for a neurodegenerative disease or personality disorder. To differentiate ADHD from neurodegenerative diseases or personality disorders, it is important to focus on the course of the problems by obtaining a complete history and a long term follow-up.
