Unsynchronized Brain Rhythms during Sleep Cause Memory Loss in Older Adults


A recent research says that older adults may be more likely to face memory disruptions due to their lost brain rhythm while sleeping. The research findings are published in the Neuron journal.

One of the authors of published study and professor of psychology and neuroscience, Matt Walker from the University of California, Berkeley said in a statement that, “It’s like a drummer that’s perhaps just one beat off the rhythm. The aging brain just doesn’t seem to be able to synchronize its brain waves effectively.”

The results appear to be answering to the question existing since long time that how the rising age can impact on memory in people, who even are not suffering from Alzheimer’s or any brain disease.

A lecturer and researchers in sleep and plasticity, Julie Seibt from the University of Surrey in Guildford, Surrey, who was not a part of research team said in that, “This is the first paper that actually found a cellular mechanism that might be affected during aging and therefore be responsible for a lack of memory consolidation during sleep.”

Walker with his associated team of researchers followed 20 young adult participants, who learnt 120 couples of words, with intent to find the output of the research.  Walker said while describing the experiment that, “Then we put electrodes on their head and we had them sleep.

Those electrodes allowed Walker and the team observe the electrical waves formed by brain while they were in deep sleep. They also monitored an interaction between the slow waves that occur 12 times or more in a second.
