    Researchers say wealthier, industrialized nations have a greater occurrence of dementia.

    A study published in the UK says people living in wealthy, industrialized countries are more likely to develop Alzheimer’s disease due to—get this—cleanliness!  Because residents of these nations are far less likely to come in contact with excessive bacteria, viruses, and other microorganisms, they could have problems with the development of their immune system, which could lead to inflammation in the brain typically linked with Alzheimer’s.  Known as the hygiene hypothesis, past research has already linked cleaner environments with a higher risk of allergies and autoimmune diseases.  The researchers said that “exposure to microorganisms is critical for the regulation of the immune system.”
