Many people take sleeping for granted, disregarding the fact that prolonged lack of sleep poses a serious risk to one’s health.

A new study has linked lack of deep sleep to Alzheimer’s disease or the loss of one’s ability to remember.

Gawon Cho, a postdoctoral associate in internal medicine at the Yale School of Medicine in New Haven, Connecticut, told CNN that they found in a study that the volume of a part of the brain called the inferior parietal region shrunk in people with inadequate deep stages of sleep.

That part of the brain is known to be an early indicator of cognitive deterioration and Alzheimer’s disease, according to Cho.

The finding reinforces the need to get enough sleep.

Meanwhile, locally, a pickup truck driver who was filmed in a video that went viral on social media became the subject of a summons from the Land Transportation Office (LTO).

In the Facebook video shared by Yamato Kenji to GMA News, the truck is shown rolling slowly on Visayas Avenue, Quezon City last week. Other cars tailed the truck, trying to stop it.

The video then shows a motorcycle rider rolling beside the truck and honking his horn. The rider then banged on the door of the truck, waking up the dozing driver.

One motorcycle was damaged after it was hit by the truck of the snoozing driver.

LTO Assistant Secretary Vigor Mendoza told GMA News they asked the owner of the vehicle to present himself on 4 April to explain what happened.
