The world's population is graying, and as a result, nations around the globe are staring down a rising tide of people who will grapple with the ravages of Alzheimer's disease and other dementias. According to a new report from Alzheimer's Disease International, some 35.6 million people worldwide will have a form of dementia in 2010. That number is expected to nearly double every 20 years, reaching an estimated 65.7 million in 2030 and 115.4 million in 2050.
A new shoe outfitted with a GPS chip aims to offer peace of mind to Alzheimer's patients and their caregivers.
The embedded GPS tracking system will allow the wearer of the shoe to be located instantly online and for their whereabouts to be monitored in real time.
The shoe may offer hope to the growing number of people with Alzheimer's disease. More than 26 million people worldwide live with Alzheimer's, and the figure is set to exceed 106 million by 2050, according to researchers at the Johns Hopkins Bloomberg School of Health.
Alzheimer's sufferers who catch a cold or a stomach bug need to be treated as soon as possible to prevent it worsening their dementia, new research has suggested.
A study by scientists at the University of Southampton found a link between the infections and an increase in inflammation-like reactions in the brain, which led to an increased rate of cognitive decline.
One of the many tragedies of Alzheimer's disease is that patients don't know until it's too late that they actually have the condition. By the time the first signs of forgefulness and confusion set in, experts believe, the disease has already been ravaging the brain for a decade or more, causing irreversible damage.
Veterans diagnosed with post-traumatic stress disorder (PTSD) have a significantly higher risk of developing dementia comparing with veterans who don't have the disorder, a study reports today.
Using data from the Department of Veterans Affairs National Patient Care Database, scientists from the University of California-San Francisco analyzed files of 181,093 veterans ages 55 and older without dementia from 1997 to 2000. The mean age at the start of the study was 68, and 97% were male.
Middle-aged adults who live alone are twice as likely to develop dementia or Alzheimer's disease later in life compared to those who are married or live with a partner. And the risk is three times higher among those who are divorced or widowed, according to a new study by Swedish and Finnish researchers.
The study included 2,000 men and women in Finland who were initially surveyed when they were 50 years old and again 21 years later.
When Diane Thornton first realized she was having trouble keeping track of appointments, she would write herself reminder notes. When she got lost on her way to the office, she'd call her secretary and ask for directions. On days she had trouble speaking or remembering words, she would avoid answering her phone.
Two European research teams have identified three genes that affect a person's risk of developing Alzheimer's disease, the most common cause of dementia in the elderly.
The new genes appear to have at least as big a role as four others discovered in the last 15 years that are known to play a role in Alzheimer's.
"The message here is that genes are important in Alzheimer's disease...and there may be multiple ways of reducing the risk that the genes produce," said Julie Williams, a neuroscientist at Cardiff University in Wales who helped lead one of the teams.
