Flashbulb Memories Dims With Age

In the article, psychologists found that some aspects of memory and processing change as people get older. Chaik, Phd. and Salthouse, Phd. have been investigating how this came to be.

Their findings show that the brain starts to decline after the 20s, and during the 40s, people start to notice change in how they remember new information. This is due to the aging of the brain having lower blood flow. This blood flow causes decrease of the efficiency of the mind." As the brain changes, so does behavior." A lot of this is due to the inability to make new long term memories.

After running series of tests, scientists felt that this decline of efficiency also affects the flashbulb memories. Of course a lot of booster methods such as brain games and classes that introduce such manner can best give improvement of retaining information. However, those flashbulb memories are forever scarred for the accuracy diminished during the aging process.

As I was scrolling down, the section about how the brain begins to decline in the 20s was intriguing so I went back to the source to learn more.
Apparently, the brain volume reaches it peak while we are in our early 20s, meaning essentially when most college students graduate (coincidental?), then begins to gradually decrease. It becomes noticeable for many in their 40s when name escape their memory or not being able to multitask as they once did - this is because the cortex begins to shrink and the blood flow slows down. Another effect this has is a person's inability to verbally communicate in an articulate way as they once did. Experts say that to combat the shrinkage of the brain, it would be wise to do something mentally challenging such as learn a new language or play a new instrument. Although reading about this was fascinating, I'm in no hurry to experience it.
