Dr. Leroy emphasised that additional research are wanted higher to grasp the connection between sleep disturbances and cognitive decline. She additionally talked about the significance of learning how MCR syndrome may contribute to or be influenced by sleep-related points and cognitive decline.
A limitation of this research was that contributors reported their very own sleep experiences, which could not all the time be absolutely correct. This issue may have an effect on the reliability of some findings.
