There are currently more than 160,000 practicing lawyers over the age of 65 in the U.S., a 50% increase from just a decade ago. But this age group is also more at risk of Alzheimer's disease or other forms of dementia. That can have serious consequences for a lawyer's clients, especially if that attorney is a solo practitioner or works in a small firm.

On this episode of On The Merits, Bloomberg Law reporter Holly Barker talks about her recent reporting on lawyers that are unaware of, or are in denial about, their own cognitive impairment. Barker says most state bars are struggling to figure out how to help these attorneys gracefully exit the profession while protecting their clients.
