Medical treatments are shifting from broad approaches to precise genetic targeting, especially for finicky diseases like Alzheimer's dementia. While many past efforts focused on amyloid β plaques, new research is exploring genetic regulators like APP, which influences amyloid levels, and KDM5, an enzyme linked to memory and cognition. Clinical trials are testing drugs that could balance these proteins and potentially slow cognitive decline at its root. Tune in this week for a deep look into the genetics of Alzheimer's
