Poor sleep may put you at greater Alzheimer's risk

Research has shown that one-third of Americans don't get enough sleep while 45% of the global population also has trouble sleeping. It can make you forgetful, tempt you to overeat, cause lethargy and raise your blood pressure.

People who sleep badly could be at a greater risk of Alzheimer's later in life, new research has suggested.

The findings of the study showed that people who reported bad quality of sleep, sleep problems and daytime sleepiness showed more biological markers that indicate the risk for Alzheimer's disease.

This is because they had either a parent with the disease or being a carrier of a gene that increases the risk for Alzheimer's disease called apolipoprotein E (APOE).

There is a growing amount of data extrapolated from research on mice and humans that show that interrupted and poor sleep leads to higher levels of a protein that forms the plaques that kills brain cells and hinders information processing.

While some of these relationships were strong when looking at everyone as a group, not everyone with sleep problems has abnormalities in their spinal fluid.

"As well as improving our understanding of diseases like Alzheimer's, knowing the precise structure of tau will help inform research into new treatments".

"It is still unclear if sleep may affect the development of the disease or if the disease affects the quality of sleep", Bendlin said. These foods relax your muscles and exhausted nerves, they contain amino acid tryptophan that encourages sleep and promote the production of sleep hormone melatonin that signals your brain to switch off and rest.

"This will require studies that directly test whether modifying sleep has a beneficial effect on the brain", Bendlin said.

It's always been known that people with Alzheimer's suffer sleep issues.

Participants were surveyed about sleep quality. In a recent study, investigators examined 101 cognitively normal individuals--with an average age of 63 years--who completed sleep questionnaires.

"It's important to identify modifiable risk factors for Alzheimer's", Bendlin said. This could explain why people with more Alzheimer's markers were more likely to report poor sleep, they added.

'It is estimated that delaying Alzheimer's disease onset by a mere five years would reduce Alzheimer's disease cases by 5.7 million and save $367 billion [£284 billion] in healthcare spending in the United States, ' she said.

"In experimental studies, there does seems to be evidence of both chicken and egg", said neuroscientist Jeffrey Iliff of Oregon Health and Sciences University. "So there may be a bio-directional interaction". According to Dr Sjors Scheres, one of the researchers, drugs aimed at the disease protein till date was akin to "shooting in the dark".

Amyloid is a protein that folds and forms plaques.

Finding out what causes Alzheimer's could be critical to stopping the disease as early as possible, before irreversible damage has been done.
