why does alzheimer’s increase the likelihood of aggression/anger in older people?
In: 263
From a science pov, Alzheimer’s tends to heavily affect the hippocampus which has a role in memory formation. As the disease progresses, patients also experience diffuse cortical atrophy of the brain, which will affect the prefrontal cortex. This part of the brain is heavily involved with the part of your mind that tells you when something is “bad” and that you “shouldn’t do it”. A simplistic explanation, but in other words, you can’t remember things and then the part of your brain that inhibits some of your “bad” thoughts/actions begins to not function correctly, so you’re confused and eventually start to act out in anger, frustration, and/or fear
