A 2023 analysis concluded that sleep disturbances, particularly nightmares, should be considered when evaluating a person's risk for dementia.
Research shows frequent distressing dreams and nightmares can link to higher cognitive decline and dementia risk among both middle-aged and older adults.
Middle-aged adults reporting weekly nightmares were found to be four times more likely to face cognitive decline compared to those with none.
For older adults, those with frequent nightmares are twice as likely to be at risk for dementia, emphasizing the potential warning signs.
