A statistical and functional correlation strategy to identify changes in cellular pathways specifically linked to impaired cognitive function with aging. Analyses using the strategy identified multiple groups of genes expressed in the hippocampi of mammals, where the genes were expressed at different levels for several ages. The aging changes in expression began before mid-life. Many of the genes were involved in specific neuronal and glial pathways with previously unrecognized relationships to aging and / or cognitive decline. The processes identified by the strategy suggest a new hypothesis of brain aging in which initially decreased neuronal activity and / or oxidative metabolism trigger separate but parallel genomic cascades in neurons and glia. In neurons, the cascade results in elevations in calcium signaling and reductions of immediate early gene signaling, biosynthesis, synaptogenesis and neurite remodeling. In contrast, glia undergo increased lipid metabolism and mediate a cycle of demyelination and remyelination that induces antigen presentation, inflammation, oxidative stress and extracellular restructuring. These identified genes and the proteins they encode can be used as novel biomarkers of brain aging and as targets for developing treatment methods against age-related cognitive decline, Alzheimer's Disease and Parkinson's Disease.

Alternative cellular energy pigments (ACE-pigments) provide a source of cellular energy other than that provided through the oxidative metabolism of foods, or in the case of plants and certain bacteria, through the process of photosynthesis. In some patients, ACE pigments exist in a form that can be further energized or activated using ultraviolet (UV) light, especially if the reaction is initially triggered by the presence of suitable dyes, such as neutral red. A method is described to further enhance the activation of the ACE pathway in humans and animals deprived of ACE. The method comprises using natural or man-made sources of ACE products (enerceuticals), with or without the inclusion of a suitable dye, such as neutral red; or other activating components, such as magnesium chloride; with the combined mixture being put into a UV transparent container, such as a plastic bag, or placed on some other material, which can be laid onto the skin and illuminated with a UV light source. The process of activating the ACE pathway is evidenced by UV inducible fluorescence seen within areas of the patients' skin and / or mucus membranes. This fluorescence fades as the ACE pathway becomes fully activated. Activating the ACE pathway can have therapeutic benefits in various infectious and non-infectious diseases including illnesses attributed to infections with stealth adapted and conventional viruses and diseases attributed to an inadequacy of the mitochondria and associated metabolic pathways, including states of hypoxia and nutritional deficiencies.
