Seniors with Poor Sleep Are 3x More Likely to Develop Cognitive Problems, New Study Reveals

New research suggests that older individuals experiencing sleep disturbances face an increased likelihood of developing Motoric Cognitive Risk Syndrome (MCR).

The findings, published in the journal Neurology by the American Academy of Neurology, indicate that older adults who experience excessive daytime sleepiness or severe sleep problems face an elevated risk of MCR.

Researchers conducted a study involving 445 participants with an average age of 76, all of whom were free from dementia. The participants were asked to report their sleep habits through a questionnaire, which included questions about nighttime awakenings and the use of sleep medications.

Among the participants, 177 were classified as poor sleepers, and 268 were considered to have good sleep quality. At the study’s outset, 42 individuals had MCR, with an additional 36 developing the syndrome during the research.

The study found that participants with excessive daytime sleepiness and a lack of enthusiasm for daytime activities were three times more likely to develop MCR than those without such symptoms.

Dr. Verna Porter, a neurologist, explained in an interview that chronic sleep disorders such as sleep apnea and insomnia can have long-lasting effects on cognitive function. She emphasized that chronic sleep issues starting at a young age may increase the risk of neurodegenerative diseases later in life.

Dr. Porter emphasized the importance of improving sleep quality by maintaining a balanced diet rich in fruits and vegetables and incorporating regular exercise. She recommended at least 150 minutes of moderate-intensity physical activities like walking, swimming, or yoga each week, along with strength training to maintain muscle mass.

For seniors, Dr. Porter stressed the importance of getting 7-8 hours of sleep per night and improving sleep quality as crucial steps toward preventing neurodegenerative diseases.
