Laughter may help stave off memory loss

Researchers from Loma Linda University in California say that laughter may actually help diminish memory loss and brain damage because it helps reduce levels of the stress hormone cortisol.

In the study, two groups of elderly people – one with diabetes and one healthy – watched a 20-minute comedic video followed by a memory test involving visual recognition, learning ability, and memory recall. A third group of elders took the memory test without watching the video. Researchers measured the cortisol level for all individuals before and after the experiment.

Both groups that watched the video recorded a slight decrease in cortisol levels compared to the group that did not see the funny video. The groups that watched the video also scored higher on the memory test. The group with diabetes received the most benefits from the video based on their cortisol levels and test results.

The results may indicate that laughter leads to better memory because it releases endorphins and dopamine and that lowers stress hormones that can damage neurons in the area of the brain associated with memory.
