What happens when hippocampus shrinks

Hippocampal shrinkage also damages cognitive functions and interferes with the process of creating memories, which has a profound impact on both behavior and the ability to form a stable, realistic, and cohesive sense of self.It is an s shaped structure which is a layer of densely packed neurons.First, neurons in the cortex jot down what our sensory neurons see and feel and hear.Some of the ways to quick­ly shriv­el it with­in months or years include stress, anx­i­ety, untreat­ed depres­sion, obe­si­ty, uncon­trolled dia­betes, seden­tary lifestyle, eat­ing junk food, and con­cus­sions.There's also some evidence that the hippocampus could regulate neurogenesis.

While mild forgetfulness occurs as part of the natural part of aging, memory problems caused.In fact, duration of stress is almost as destructive as extreme stress.The hippocampus is responsible for regulating memory, spatial navigation, and conflict avoidance.+ and − represent an increase and decrease …Here, neurons are injured and die throughout the brain, connections between networks of neurons break down as well.

For example, age, in addition to affecting fitness, also has a direct effect on hippocampus size.Studies have shown that atrophy of the hippocampus also correlates with mild cognitive impairment.One of those parts is called the hippocampus.The hippocampus is about 1/100th of the size of the outer layer of the brain, or cerebral cortex.Some animal studies, though, show that high levels of cortisol may play a role in damaging or destroying cells in the hippocampus.

But studies show that the shrunk hippocampus can be there before the disease.
