Canadian scientists from the University of Montreal have shown that older people suffering from insomnia have a greater risk of memory problems. This means that they are more often threatened by senile dementia.
The study is based on data from more than 26,000 people aged 45 to 85. Over a long period, they reported on the quality of sleep, while scientists put them through cognitive tests. The worse people slept, the lower their test scores were. Insomnia was strongly associated with memory impairment when compared to people who had only occasional episodes of insomnia or had no sleep problems at all.

The memory deficit found was specific because the researchers also explored other areas of cognitive function, such as concentrating while multi-tasking. But the differences are set only in the memory area. Unlike previous studies on sleep quality, the current one relies on a significant data set and focuses specifically on sleep disturbances.

This is not just tossing and turning in bed at night, but a real diagnosis, which requires the presence of a number of symptoms that persist for three months. And every year, scientists receive more and more data about the serious consequences of insomnia in the body. (READ MORE)
