What science tells us about about memory and the brain, including how brief lapses and serious issues happen.
There are so many reasons—normal, non-scary reasons—why we forget things, whether it’s the name of that dog-walking neighbor, or our friend’s birthday, or where we parked our car. Sometimes we’re moving at too fast a pace, multi-tasking all the way. Or maybe our lives are full of too much stress and too little sleep. Of course, there are more serious and definitely scary-to-consider reasons why people become forgetful—and those are the ones we worry about.
Stress has been shown in multiple studies to affect how our brain stores and retrieves memories. When you’re under high stress the body releases the hormone cortisol, which affects parts of the brain involved in the processing of memory.When cognition declines“Some loss of cognitive function—age-related cognitive decline—is normal at a certain point,” says Tracy. Everyone experiences it as they get older, to some degree or another.
