A World Health Organization expert released a video explaining the early signs of dementia to help the public identify symptoms and seek intervention [1].
Early detection is critical because it allows patients and caregivers to plan for the future and access supportive care before cognitive decline progresses. Identifying these signs helps distinguish between normal aging and the onset of a medical condition.
The video, published on the WHO YouTube channel, aims to raise awareness so that detection can happen sooner [1]. The expert said specific behavioral and cognitive changes may indicate the start of dementia and urged viewers to seek professional assessments promptly.
In the U.S., the scale of the issue is significant. More than seven million Americans aged 65 and older have Alzheimer's disease, which is the most common form of dementia [2]. Despite the prevalence of the disease, many patients face significant delays in receiving a formal medical confirmation.
Wait times for a dementia diagnosis are often extensive. These wait times range from 12 months to nearly four years [2]. Such delays can prevent patients from receiving timely treatments or lifestyle adjustments that may slow the progression of symptoms.
WHO said that knowing the difference between occasional forgetfulness and persistent cognitive impairment is the first step toward a diagnosis. The organization encourages families to document changes in memory, mood, or personality before visiting a healthcare provider to ensure a more accurate clinical evaluation [1].

The gap between the onset of symptoms and a formal diagnosis—sometimes spanning years—indicates a systemic failure in early screening and healthcare access. By leveraging digital platforms like YouTube, the WHO is attempting to bypass traditional clinical barriers to educate the public directly, potentially reducing the time it takes for patients to enter the healthcare system.
