Sleeping Less Than 6 Hours a Night Linked to Higher Dementia Risk, Scientists Show

The links between poor sleep and symptoms of dementia have been studied for years, but there's still much we don't know about how lack of sleep may contribute to cognitive decline in conditions like Alzheimer's disease.  One of the limitations in our data is many observational studies looking at sleep duration and dementia have relatively short follow-up windows, or only examine senior individuals at their outset – whereas the development and manifestation of dementia symptoms often take place over decades, and can start emerging much earlier in people's lives.To provide a longer-term analysis examining how sleep in the years leading up to old age might affect dementia outcomes, a research team led by first author and epidemiologist Séverine Sabia from the University of Paris looked at da...

The Brain's Pleasure System Wastes Away in Early-Onset Dementia, Study Finds

Dementia is a thief that picks many pockets. In some guises, it takes our memories. Other forms rob us of inhibition. Sometimes it even takes away happiness itself.A new study has shown for the first time how some forms of early-onset dementia are associated with a profound loss of pleasure linked to a wasting of 'hedonic hotspots' – brain regions associated with reward seeking.  An absence of pleasure is known as anhedonia, and it's a common symptom in mental health conditions such as depression and obsessive-compulsive disorder.  Where most of us are rewarded with a sense of satisfaction, excitement, and bliss when we achieve a goal or associate with loved ones, those experiencing anhedonia can't.Interestingly, early dementia is often confused with depression, and a decline in motivatio...

What Is Dementia-Related Psychosis?

More than 2 million Americans have dementia-related psychosis. If you have a loved one who has dementia, you know that it can be a scary condition -- for both those going through it and for their caregivers. When they have to deal with psychotic episodes, too, it can be even more unnerving."But instead of thinking psychotic features as this taboo, icky subject, I just want people to understand that it's a normal manifestation of these illnesses. An expected manifestation. A disease talking," says Pierre N. Tariot, the director of the Banner Alzheimer's Institute in Phoenix, AZ."Your loved one is not 'crazy.' They're ill. Their brain isn't functioning properly. And we can evaluate that, and we can help you understand that. And we can help relieve the distress -- yours and your loved one's."...

Recognizing the Symptoms, From Hallucinations to Delusions

Many of the 50 million people or so who are living with dementia also have psychosis. You may hear doctors use the term "psychotic episodes." It's when a person struggles with determining what is real and what is not.It can include things like:A false belief that a caregiver is trying to harm themAn insistence that they see someone in their room, like a long-dead sibling or friend, or even someone famous, who isn't thereOften, experts say, the signs of dementia-related psychosis go undetected and untreated for too long. That can have a big impact on both the health of the person with dementia and the well-being of their families and other caregivers."If somebody has dementia, the doctor or the family may not take seriously some of the things the [person is] saying, and not recognize that i...
