Key mechanism has been discovered which prevents memory loss in Alzheimer's disease

Neurons communicate with one another by synaptic connections, where information is exchanged from one neuron to its neighbor. These connections are not static, but are continuously modulated in response to the ongoing activity (or experience) of the neuron. This process, known as synaptic plasticity, is a fundamental mechanism for learning and memory in humans as in all animals. In fact, we now know that alterations in synaptic plasticity are responsible for memory impairment in cognitive disord
