Good Lifestyle

When we think of aging, it is difficult not to worry about the possibility ofcognitive decline. Science and researchers work to better understand dementia - which currently has no remedy - and to identify the factors that could put somePersons at risk. Now a new study has drawn attention to a night practice that could keep your brain healthy. Read the rest to find out how to reduce the risk of your dementia by making an adjustment tonight.

In progress research on dementia has contributed to identifying a number of life changes that can really avoid cognitive decline. Dust your French or mandarin could be a proactive approach, as experts suggest speakingtwo or more languages could have a positive effect onLong -term cognitive health And reduce your risk of Alzheimer's disease - the most common form of dementia. In addition, a 2015 study published inThe Journal of Neuroscience suggested thatSleep on the side can help yourThe brain emerges from waste More effectively, lowering your risk of Alzheimer's disease and Parkinson. However, there is another sleep habit that could affect your cognitive health - and that could make you consider changing your morning alarm.

A study published on April 28Aging of nature identified theideal sleep quantity For adults of middle and older age, at seven o'clock at seven o'clock. When sleeping hours were below or above this number, researchers from the University of Cambridge in the United Kingdom and Fudan University in China found that study participants had more cognitive performance Low, affecting memory, treatment speed and the ability to solve problems. According to the researchers, the association indicates that the duration of the sleep could be a risk factor for cognitive decline as we age, which is a "characteristic symptom" of Alzheimer's disease and dementia.

Unfortunately, a solid sleep becomes more difficult as we age, characterized by difficulties in falling asleep, to remain asleep and to reduce the quality and the amount of sleep. According to researchers, finding solutions to these sleep challenges is essential for older populations.

""Have a good night's sleep is important at all stages of life, but especially as we age, "author of the studyBarbara Sahakian, SCD, FMEDSCI, professor at the Cambridge Psychiatry Department, said in a press release (via Sciencedaily). "Finding ways to improve sleep for the elderly could be crucial to help them maintain good mental health and well-being and avoid cognitive decline, especially for patients with psychiatric disorders and dementia. ""

When we do not get the right amount of sleep, something called slow wave sleep is disrupted, the researchers said. According toNature wallet, it's theThird wave of sleep And is the deepest phase of the sleep of non -fast eye movements (Nrem). Experts think that memory consolidation occurs during this sleep phase, as well as the amyloid deposit - the process when the amyloid plate regroups and forms deposits in the brain, that some researchers think that the main cause of the disease Alzheimer's.AE0FCC31AE342FD3A1346EBB1F342FCB

Investigators noted that their results are supported by previous studies, which have identified a link between the duration of the night sleep and the risk of Alzheimer's disease. In this study, one of the most important brain structures involved in the ineffectiveness of sleep was the hippocampus. As the hippocampus plays a role in memory processes and in Alzheimer's disease, researchers cited this observation as being particularly important.

Investigators studied data from 498,277 people connected to the Biobank of the United Kingdom. Participants between 38 and 73 years old completed tactile questionnaires on their sleep practices and mental health and also carried out various cognitive tests.

In addition to the link with cognitive performance, the researchers found that obtaining seven hours of sleep was linked to better mental health. Plur more or less than seven hours of sleep led participants to the study with more symptoms of anxiety, depression and mania, as well as overall well-being.

Investigators said that the link between sleep and cognitive problems is not yet final, but that previous studies have linked abnormal sleep to changes in brain structures in this population, the subject requires additional research.

"Although we cannot say in a conclusive way that too little or too much sleep causes cognitive problems, our analysis examining individuals over a longer period seems to support this idea", author of the studyJianfeng Fengsaid a professor at Fudan University, in a statement. "But the reasons why the elderly have a lower sleep seem complex, influenced by a combination of our genetic composition and the structure of our brain."

The study was also limited because it only approached sleep hours and no other sleep hygiene elements. The study pool mainly included white participants who self -declamed their sleep habits, which means that they were not objectively measured. Finally, investigators did not take into account overall health and how it could come into play with individual sleep habits.
