Something may already be changing in someone you love — and it may not look like memory loss at all. In this powerful conversation, Dr. Hiroshi Nakamura explains the subtle early signs of dementia that families often overlook for years. From personality shifts and emotional withdrawal to poor judgment, language struggles, sleep disturbances, and changes in behavior, this video reveals what cognitive decline can actually look like before obvious memory problems begin.
You’ll also learn about medical conditions that can mimic dementia — including vitamin B12 deficiency, thyroid disorders, depression, medication side effects, sleep apnea, and more — and why early evaluation can make an enormous difference.
If someone you care about “just doesn’t seem like themselves anymore,” this video will help you understand what to watch for, how to respond compassionately, and why waiting can sometimes do more harm than good.

• How judgment and decision-making begin to change

1. Insulin resistance (pre diabetes).
2. Disruption of the oral biome and/or gut bacteria.
3. Poor sleep
4. Inflammation
5. Lack of exercise
6. Stress
Yet no one i speak with says anything. Its like "am i noticing what they do not notice?" Or "are co-workers too young to even preceive i am struggling finding words in light general conversations?".
Regardless, it is truly scary to watch my own brain change ever so slightly.
It may be stress... and it may be a topic i really do not want to go in depth with someone i only know on a work- basis.
It has made me decide to retire this year instead of waiting an extra year or two.
Hoping that helps my stress and brain!
Just a humble observation.
Dementia is in my family and I had a friend with dementia symptoms too. He was an alcoholic and was deficient in Vitamin B12. Sadly, he died on his bed alone when he was 53 years old because he refused to admit he had an alcohol problem 😢
