LONDON: Are you experiencing fragmented sleep? If yes, then it's high time that you consult a doctor, for a study says it affects the ability to build memories and could raise the risk of developing dementia in later life.
"Sleep continuity is one of the main factors affected in various pathological conditions that impact memory including Alzheimer's disease and other age-related cognitive deficits," said Dr Luis de Lecea, who led a team at Stanford University which carried out the study.
Researchers have, in fact, based their findings on an analysis of laboratory rodents , the findings of which are published in the latest edition of the 'Proceedings of the National Academy of Science' journal. In their study, the researchers found disrupting sleep made it harder for the animals to recognize familiar objects.
Broken sleep also affects people addicted to alcohol, and those with sleep apnoea. The researchers add there is no evidence of a causal link between sleep disruption and any of these conditions. But they added: "We conclude that regardless of the total amount of sleep or sleep intensity, a minimal unit of uninterrupted sleep is crucial for memory consolidation."
