In epilepsy, poor sleep is associated with dementia (opens in new tab)

For people with epilepsy, getting poor sleep was associated with a higher risk of dementia compared to people without epilepsy, according to a study published in Neurology. In addition, getting optimal sleep, six to eight hours a day, is associated with higher cognitive scores than getting poor sleep, less than six or more than eight hours a day. The study does not prove that poor sleep quality causes worse cognition and dementia risk; it only shows an association.
