(WBBM NEWSRADIO) — The danger of dementia has been dialed up, with a new study sounding the alarm.
Over 40% of people over the age of 55 in the U.S. are likely to develop dementia later in life, according to the new research published in the journal Nature.
“I've been with the association for 11 years, and every year it keeps just rising and rising – the numbers. So what we know is that this is a global crisis,” Senior Manager of Education & Community Volunteers at Alzheimer’s Association Illinois Chapter, Hadi Finnerty said.
Taking longer to recall a name or where you put your keys is typical with older age. But dementia isn’t that. It's a progressive loss of memory, language and other cognitive functions.
However, for adults forgetting names or misplacing items, Finnertay says not to panic.
“Because sometimes it's not Alzheimer's or dementia. It could be thyroid abnormalities. It could be vitamin deficiencies. It could be depression that's playing a role.”
While genetics and aging drive most cases of dementia, the study shows that nearly half could be prevented or delayed by managing risk factors like weight, diet, mental health, and hearing loss. Additionally, exercise, nutrition, keeping your brain active, and keeping social can also help delay or prevent onset.
That age marker of 55 might sound young, but Finnerty says it is not that uncommon.
“Bruce Willis had his diagnosis. Wendy Williams, you know, they're younger, so it's not as rare.”
The study also found Black adults face higher risks in earlier onset compared to white adults.
Socioeconomic factors including limited access to care and nutrition, may play a role.
