Combating the persistent death of neurons is a long-standing challenge in treating Alzheimer’s disease, in which neurons are forced into programmed cell death, causing cognitive decline. Once neurons die, the brain lacks the capacity to simply replace them. Current therapies can only slow neuronal degradation and cannot replenish the loss of neuronal circuits within the brain.…
