How long older adults sleep could affect their brain health, according to a study published Monday in the journal JAMA Neurology.

Disrupted sleep is common in late life, the study authors wrote, and associated with changes in cognitive function -- the mental capacity for learning, thinking, reasoning, problem-solving, decision-making, remembering and paying attention.

The"amyloid hypothesis," one of the leading theories on the culprit of this destruction, suggests accumulation of the protein might disrupt communication between brain cells, eventually killing them. Previous research has suggested"that sleep may both help to limit the production of amyloid in the brain and support the drainage system that clears it," said Laura Phipps, head of communications at Alzheimer's Research UK, who wasn't involved in the study, via email.

How Depression Changes People's VisionNew research suggests depressed people process visual information differently. It has saved me thousands of dollars in flights (and continue to do so) any longer than 90 minutes. I can only get 1-2 time zones away. Pretty weak effort view: people are different by nature because of their experiences & how they are brought up. That already casts a unique difference on how they see the world. For emotions and mental challenged few, they will have more colored filters to their vision to the world. The current leading treatment for depression is cognitive therapy, which operates under the assumption that the depressed patient is sad because he is misperceiving his environment. That patient is only remembering negative things and failing to perceive the positive.
