Turns out that feel-good hormone dopamine (you experience it when pleased or motivated) can help out your sluggish memory as you age. Researchers have found that dopamine specifically affects episodic memory. This is the part of long-term memory that allows us to recall actual events, and happens to be the first part of the memory affected in Alzheimer’s dementia. This finding will allow scientists to study Alzheimer’s disease in more depth and better understand why memories fade more quickly after the disease’s initial onset. Their finding—that memories can be influenced—provides hope for Alzheimer’s patients and their families.
