A recent research, published in the European Respiratory Journal, finds that sleep apnea, a common disorder that interferes with the breathing while sleeping, is connected to the changes in brain structure similar to changes seen in early dementia.
For the study, 83 participants were involved with the age from 51 to 88. They reported memory and mood problems to their doctors. None of them was diagnosed with obstructive sleep apnea (OSA) They underwent memory tests and MRI brain scans.
Having analyzed the received data, the scientists concluded that a low level of oxygen in blood during sleep was associated with the loss of thickness of the right and left temporal lobes of the brain. These brain structures play important role in memory processes and proved to be changed in dementia.

A new study that included about one million people in Britain finds that people who wake up late, so-called night owls, have 10% higher risk of dying sooner than people who rise and set with the sun.
For the study, the scientists have analyzed information on more than 430,000 people aged from 38 to 73 from a public database, who defined themselves as “definitely a morning person” (27%), “more a morning person than evening person” (35%), “more an evening person than a morning person” (28%), or “definitely an evening person” (9%).
One of the authors of the study Kristen Knutson of Northwestern University in Chicago says: “The higher risk may be because people who up late have an internal biological clock that doesn’t match their external environment. It could be psychological stress, eating at the wrong time for the body, not exercising enough, not sleeping enough, being awake at night by yourself, maybe drug or alcohol use.”
Previously, it was thought that senior people just need less sleep than youth, but a new research has discovered that adults begin losing their ability to lapse into a deep and restorative sleep from about their middle thirties.
For the study, the researchers analyzed the scientific literature published in the medical journal Neuron. The scientists also found that we also start showing signs of aging.
One of the authors of the study Professor Matthew Walker says that it is the lack of sleep also linked to a number of deadly diseases, especially those affecting the brain. He explains: “Sleep changes with aging, but it doesn’t just change with aging; it can also start to explain aging itself.”
For the study, a team of scientists fed 3-week-old male rats a diet of either standard chow or chow with prebiotics. The rats that consumed prebiotics spent more time in rapid-eye-movement sleep.
The researchers from the University of Colorado Boulder that executed the study say: “It is possible that a diet rich in prebiotics started in early life could help improve sleep, support the gut microbiota and promote optimal brain/psychological health.”
