Discover the main triggers who can cause recurrent nightmares; Science explains the phenomenon
Do you usually have many nightmares? Why, after all, that they come at night? According to science, the ugly recurring dreams can be more than a simple night discomfort. A study, recently presented in European Academy of NeurologyIt suggests that they can work as a “warning sign” for cognitive problems. The adults and the elderly of middle -aged who often face nightmares have a high risk of developing cognitive decline and even dementia.
Higher risks for the brain
The research, conducted by experts of the Imperial College LondonHe accompanied two groups over the years: 605 middle -aged adults for over 13 years and 2,600 elderly people for 7 years. The results attracted attention: those who reported nightmares at least once a week had risks four times higher than cognitive decline and more than double the chances of developing dementia.
Although stress, anxiety and depression are already known to cause disturbing dreams, scientists have observed that genetic factors can also influence. Some genes may make some people more vulnerable to have frequent nightmares, which can also be related to predisposition to brain diseases. The team also highlighted the connections with conditions such as the Parkinson’slupus and even childhood disorders, such as the Attention deficit disorder and hyperactivity (ADHD).

The nightmares occur during the REM phase of sleep and can be caused by several factors. Among these are: intense stress or emotional trauma; Sleep deprivation; use of specific medicines; abuse or interruption of the use of alcohol and drugs; frightening movies or readings before going to bed; Disorders such as depression.

At this point, they can be considered a sleep disorder. Symptoms include vivid and distressing dreams; Often wake up with a fast heart and sweat; difficulty in returning to sleep; And sensations of fear, sadness or irritation when he wakes up.
Nightmares as a clinical sign
Based on data, researchers support a new clinical position in front of nightmares. Healthcare professionals should pay more attention to relationships, especially in older patients. Identifying the problem in advance can allow interventions that delay or even prevent the progress of this cognitive decline. In addition, some strategies can help control the frequency of nightmares. For example:
- Keep regular times to sleep and awaken;
