Cambridge: In a finding that could lead to new treatment for insomnia, a new study has claimed that sleeplessness may actually shrink a person`s brain. The University of Cambridge study- the first to link insomnia to a reduction in vital grey matter- showed that those with chronic sleep problems had lower grey matter density in brain areas used to make decisions. Dr Ellemarije Altena, who led the research, said, "The findings predict that chronic insomnia sufferers may have compromised capacities to assess stimuli.” “This could have consequences for other thought processes, notably decision-making," she said, adding that their finding could pave way for new treatment for those who struggle with sleeplessness as the brain areas are also used to regulate rest. For their study, the scientists compared the brains of chronic insomnia patients to normal sleepers.
However, the researchers are not yet able to pin down whether sleeplessness precedes grey matter loss or the other way around. ANI
