In this segment Dr. David Perlmutter explains that the brain’s exceptionally high energy requirements make it especially vulnerable to metabolic problems. He argues that metabolic defects in the brain—issues with how the brain creates and uses energy—appear 20 to 30 years before any clinical signs of Alzheimer’s disease, such as memory loss or difficulty performing purposeful activities. These early metabolic disturbances are therefore the first site of pathology, preceding the later cognitive symptoms that define Alzheimer’s.

The brain is very energy hungry and as such problems with metabolism, how it creates the energy, would be very obvious then in the brain and it's really the first place to suffer. The reality is that the metabolic defects of the brain that presage to the development of Alzheimer's disease begin 20 to 30 years prior to the clinical manifestations, in other words, the changing in memory, the issues with carrying out purposeful activities.
