Cognitive decline is driven by a number of underlying interacting changes in the brain that, together, gradually and significantly cause a decline in brain function. There are three key underlying changes in the brain that cause this decline:

  1. A slowing in brain processing speed.
  2. A weakening of brain signals from the senses.
  3. A decrease in the production of key brain chemicals (neuromodulators).
