A new study revealed that dreams can reveal a lot of information about brain health, especially when it comes to nightmares that prompt you to wake up with fright, or even bad dreams that do not prevent you from continuing to sleep.
The study, published in the eClinicalMedicine journal, and prepared by a researcher in the Department of Neuroscience at the University of Birmingham, UK, Abideme Otaiko, stated that these nightmares or bad dreams that recur in middle or old age, may be linked to a higher risk of developing Alzheimer’s dementia. One of its most common types.
The study indicates that nightmares may first be an indication of the first symptoms of dementia, including problems related to poor memory, and that frequent nightmares and bad dreams may be a cause of dementia and not just an indicator of it.
The researcher stated, in a summary published by himself on the conversation website, that he analyzed health data for 600 people between 35 and 64 years old, and 2,600 people aged 79 years or older, and all the participants did not have symptoms of dementia at the beginning of the study, which the researcher started collecting its data. Since 2002.
The researcher found that the middle-aged participants who had bad dreams on a weekly basis, were four times more likely to suffer in the future from a decline in their cognitive abilities, which is one of the biggest precursors of dementia.
On the other hand, it was found that the elderly participants who suffer in their sleep from the same phenomenon are twice more likely (than people who do not have these dreams) to develop dementia.
The study showed, according to the researcher, that men are more susceptible to dementia than women, as the percentage is more than four times for men who are exposed to nightmares compared to those who are not exposed to them, while the percentage for women is not more than 41 percent, whether among the elderly or the elderly. Those who are middle aged.
But it is not inevitable, according to the researcher, and there are multiple ways to overcome nightmares and avoid their recurrence, which leads to slow deterioration of cognitive abilities and stops the development of dementia. The researcher does not refer to these methods, but previous experts advise a sports routine in the day, regulating sleep hours, avoiding stimulant drinks, relaxing, and avoiding eating directly before bed.
A study carried out by researchers from Uppsala University of Sweden, the results of which were published in the journal Neurology, concluded that a lack of sleep for one night may have a serious impact on Alzheimer’s disease. She reported that healthy men, if they can not sleep properly in just one night, they have a higher level of the protein “tau”, which is common in people with Alzheimer’s.
