The Congress Office of Technology Assessment produced key reports which claimed that environmental medicine had for too long concentrated on cancer, and ignored impacts on the brain, including dementia. This hidden hunger often stems from land degradation and forest depletion compounded by population pressure.
Improved literacy reduces population growth.
But intellectual decline reduces literacy, increasing population, and precipitating a regressive spiral. The Decade of the Brain has seen these two parallel concerns. Presence-absence synergism is largely ignored, yet this is significant. The full extent of EMID The evidence jigsaw Lead pollution and iodine deficiency are well-known causes of EMID, but there are many others. This could surpass the significance of lead, because these chemicals are persistent and there is no clinical treatment.
