Study finds link between dementia and lack of sleep - The Globe and Mail

The researchers’ findings, published Wednesday in the journal Science Advances, indicate disrupted sleep may contribute to changes in a type of immune cells in the brain called microglia, which in turn, appear to be related to poorer cognitive functions, such as memory and the ability to reason.

While further research is needed to determine whether fixing people’s sleep problems can prevent or reverse cognitive decline, Andrew Lim, one of the authors of the study, said fragmented sleep should not be ignored.

Many people believe “having bad sleep is just part of aging, and it’s something that’s annoying but to be tolerated, rather than aggressively managed or aggressively investigated,” said Dr. Lim, an associate professor of neurology at the University of Toronto and sleep neurologist at the Sunnybrook Health Sciences Centre. “This adds one more reason to take sleep problem seriously and to look for your treatable causes and to address them.”

This study builds on previous research, including studies on rodents and genetic studies, that suggest microglia play a role in the link between poor sleep and cognitive impairment and dementia. Microglia normally help fight infections and clear debris from the brain. But dysfunction of microglia appears to be involved in the development of Alzheimer’s disease, Dr. Lim said.

Sandra Day O’Connor, first female justice on U.S. Supreme Court, reveals she has dementia - The Globe and Mail

Ms. O’Connor was born in El Paso, Texas, and grew up in Arizona on the Lazy B Ranch, 250 square miles of high desert along the state’s border with New Mexico. Her upbringing has remained a point of pride, and she has often referred to herself as a cowgirl.

“It is possible to survive and even make a living in that formidable terrain,” she wrote in her memoir of her childhood, “Lazy B,” in 2002. “The Day family did it for years; but it was never easy. It takes planning, patience, skill and endurance.”

She left Arizona for Stanford Law School, where she finished third in her class in 1952. It was also where she met her future husband, a fellow law-review editor at the university.

The top graduate in her class was William H. Rehnquist, the future chief justice, who received a clerkship on the Supreme Court.

July 21: Letters to the editor - The Globe and Mail
Dealing with dementia

Re Health Care: Ontario Aims To Expand Care for ‘Difficult’ Dementia
Patients (July 19): “Experts believe that in many cases difficult
behaviour could be avoided or more easily controlled if it is properly
understood.” So when my dementia-ridden mother suddenly swung her cane
like a baseball bat at my face, it could have been prevented if I’d been
trained to “understand” her behaviour? Aggression, irrationality, anger
& frustration combine with a loss of inhibitions & judgment to
make maniacs out of what were once nice, rational people. Understanding
behaviour may help caregivers to forgive, but it won’t help Mom.

Her nursing home needs extra staff (but has none) to care for my mother
because she physically resists all help but can do nothing for herself.
Send 4 of those 700 new health-care workers to bathe Mom, brush her
teeth, wash her hair & trim her nails & that will make a
difference. But tell them to watch out. She bites.

Brenda McMillan, Toronto.

Seven health risks that could lead to Alzheimer’s - The Globe and Mail
PUBLIC HEALTH REPORTER— From Wednesday's Globe and Mail
Published Tuesday, Jul. 19, 2011

The seven risk factors, in descending order of magnitude, were identified as:

* Low education: "Use it or lose it" is an important credo in Alzheimer's prevention. Schooling is key because stimulating the brain builds neural networks and the more education a person has the more likely they are to engage in stimulating brain activity.

* Smoking: Among other things, smoking weakens blood vessels and it affects blood flow to the brain. But almost one-third of adults in the world still smoke. The research estimates 13.9 per cent of Alzheimer's cases are linked to smoking.

* Physical inactivity: Studies show that people who are physically active have better cognitive abilities and are less likely to develop dementia. Worldwide about one in six people are inactive. The new study found that 12.7 per cent of Alzheimer's cases were likely due to inactivity.

* Depression: People who suffer from depression have more than double the risk of developing dementia. About one in seven people in the world will suffer from serious depression. Researchers calculated that about 10.6 per cent of Alzheimer's cases could be traced to depression.

* High blood pressure: About one in nine people in the world have hypertension in middle age. The study estimated that poorly-controlled blood pressure accounts for 5.1 per cent of Alzheimer's cases.

* Diabetes: Research shows patients with type 2 diabetes have a significantly higher risk of developing Alzheimer's. Globally, almost seven per cent of adults have diabetes. The research team found it could be responsible for about 2.4 per cent of Alzheimer's cases.

*Obesity: Women and men who are obese at middle age have an increased risk of dementia later in life. Worldwide about 3.5 per cent of the population is both obese and middle-aged. The study found that obesity is associated with about two per cent of Alzheimer's cases.

Why Canada needs a national strategy on dementia
September 18, 2010 | The Globe and Mail | by André Picard.
"Canada's health and welfare systems are woefully unprepared for a
coming crisis. The Alzheimer Society is pleading for a national action
plan, as it has repeatedly in its 32 years of existence. Yet the federal
government refuses to invest in a strategy for dementia to match those
already in place for cancer, heart disease and mental health. The Health
Minister is refusing even to meet a new independent group of leading
researchers in the field.

So, today and next week, The Globe and Mail's journalists do what the
government would not: They consult experts, from renowned scientists to
the members of dementia victims' families, gathering facts and recording
personal experiences with the devastating disease. They also present a
seven-point plan to grapple with the coming crisis. It is only a
starting point, but if we don't begin the quest for desperately needed
solutions, more and more of us will slip away."

Well - Physical Toll of Dementia Often Overlooked in Treatment -
October 19, 2009 | New York Times | By TARA PARKER-POPE . The
lack of understanding about the physical toll of dementia means that
many patients near the end of life are subjected to aggressive
treatments that would never be considered with another terminal illness.
