If you get less than 7 hours of sleep a night, and you need a regular amount, it could spell danger for your brain.
A whole host of Americans are sleep deprived. According to the Centers for Disease Control and Prevention (CDC), one third of adults in the U.S doesn’t get enough sleep, and is resting for less than the recommended minimum of seven hours at night.
The information is based on self-reported data, and so answers could be slightly off, but still, it paints a negative picture. Apart from being less productive and increasing the risk of developing high blood pressure, diabetes and constant mental distress, those who regularly lack enough sleep are laying the groundwork for developing dementia later in life.

The study analyzed data from two previous studies called the Rush Memory and Aging Project and the Religious Orders Study, and focused on people older than 65 years of age.
