Dementia risk nearly doubles among those with common sleep disorder, study finds

In the latest evidence of the direct relationship between Sleep and healthThe researchers found that chronic insomnia can significantly increase the risk of dementia.

This is equivalent to an acceleration for three years Brain agingAccording to the study, published in neuroscience, the American Academy of Neuroscience.

The study pursued 2750 healthy, cognitive adults with an average of 70 years over a period of more than 5 and a half years. Nearly 16 % of them suffered from chronic insomnia, according to a press press statement.

“Chronic insomnia” is defined as a struggle for falling and/or staying asleep – which differs from people trying to follow the “ideal sleep”, according to the author Draigo G. Carvalho, PhD in Medicine, from Mayo Clinic in Rochester, Minnesota.

“Chronic insomnia has been associated with an increased risk of infection by 40 % of the development of cognitive weakness and dementia,” Carvalho, a member of the American Academy of Neuroscience, told Fox News Digital.

Throughout the study, 14 % of people with chronic insomnia developed a mild or dementia, compared to 10 % of those who had no. Sleep disorder.

The researchers were surprised when it was found that participants who suffer from chronic insomnia who have been more than usual than usual had less than white stains in the brain – areas where small vessels may have damage to the brain tissue, which have been linked to brain diseases.

Additional tests also found that this group recorded less in thinking skills. This was after controlling other factors such as age, high blood pressure, sleep medications and sleep -stopping diagnoses.

Participants who suffer from chronic insomnia with a decrease in the duration Alzheimer’s disease “The vascular brain disease,” Carvalho said.

People who have APOE ε4 geneThe study found that more risks associated with Alzheimer’s disease were more likely to show greater declines in memory and thinking skills.

Based on these results, chronic insomnia can be a dangerous factor that can be adjusted to poor perception and dementia, according to Carvalu.

“This enhances the importance of treating chronic insomnia – not only to improve sleep quality, but it is likely that Protect brain health With our age, our results also add to an increasing range of evidence that sleep is not only related to comfort – it also relates to brain flexibility. “

Dr. Mark Siegel, the chief medical analyst at Fox News in New York, did not participate in the study, but said that he showed an “important link” between sleep deprivation, dementia or cognitive weakness.

He told Fox News Digital: “We already know that the self-brain waste is waste of waste during sleep, and that sleep depends on the brain cells-but we still do not know whether the effect that was observed here is directly due to the lack of attention from insomnia (upon test) and memory effects that may be short-term,” he told Fox News Digital.

“The issue of actual nervous degeneration due to insomnia is possible, but this study has not been proven.”

Siegel added that the cognitive decrease may be directly due to the same insomnia or the collapse of the brain function that occurs as a result.

Dr. Ernst Li Murray, a Anti -nerve physician from the Board of Directors At Jackson Madison County General Hospital in Jackson, Tennessee, he confirmed that chronic insomnia has long been known to lead to health concerns, nervously and non -reverse.

“The study confirms that up to a short period of chronic insomnia can lead to possible harmful traces of perception later in life,” Murray, who did not participate in the research, told Fox News Digital.

“The study also showed that chronic insomnia changes the structure of the brain by increasing the changes in the white matter that was usually witnessed in patients with vascular diseases, such as High blood pressure and diabetes“

The researcher indicated that the study has some restrictions.

“We had no tools to assess the intensity of insomnia in the first place or over time,” Carvalho told Fox News Digital. “We lack sleeping data longitudinally to consider the duration of sleep over the years.”

Researchers were also unable to adapt to patients who have received a treatment for sleep stop, such as CPAP treatment.

“We also had no full information about the duration of use or doses of sleep medications,” Carvalho added.

He also emphasized that the study does not prove that insomnia causes directly Brain agingJust that there is a relationship between the two.

Anyone who suffers from insomnia on a frequent basis should talk to their doctor about excluding possible medical causes.

“Cognitive behavioral therapy may include, or Pharmaceutical It may be an option. “

The researchers recommended adopting better sleep practices, including disposal of caffeine drinks in the afternoon, lowering alcohol consumption, avoiding large meals or exercising before going to bed, and reducing exposure to electronics before bed.

The researcher warned that the pursuit of “perfect sleep” can sometimes lead to an obsession with excessive tracking of sleep data, which leads to “performance anxiety”, which can have an opposite effect.

“Tracking does not help in your sleep – Good sleep practices He said.

He also urged Carvalho to be careful when it comes to giving birth control pills for a better sleep.

“Although sleep medications can help and have patients with chronic insomnia, they do not work very well in the long run if good sleep practices are not adopted,” he said. “There is no solution to the weakness of sleep issues that do not start with the patient who does the right things.”

Murray repeated the importance of good sleep cleanliness, including not using electronic devices in bed and reducing the amount of light exposure in the room to enhance the quality of sleep.
