Timely diagnosis of dementia: the contribution of non-medical and informal contacts.

Non-medical community contacts—librarians, hairdressers, home aides—are uniquely positioned to identify early cognitive concerns in their older customers. This Dutch survey study finds these individuals often feel responsible to act when suspecting dementia, with about half of participants reporting they acted on their concern. Enhancing diagnostic timeliness requires equipping these observers with clear communication tools and referral guidance, though broader sampling is needed to validate findings across diverse settings.
