The brain gut connection refers to the idea that No answer is correct O Diseases like Parkinson s start with disruptions to neural function that then act directly on the gut to reduce microbial diversity The same microbes that occupy the gut are also found in the brain Microbes in the gut produce substances that can travel to and affect the brain via nerves the immune system or through circulation Endocrine disrupting chemicals affect both the gut and the brain although through different epigenetic mechanisms

The gold standard neuropathological evidence for Alzheimer s disease are the plaques and tangles in brain tissue True O False

According to Bredesen one of our guest speakers Alzheimer s disease AD O Is analogous to an autoimmune disease where the body s defense system attacks itself O Mechanistically is linked to APP being cut at three sites resulting in four pieces rather than at one resulting in two pieces O Occurs when neuroblastic processes overtake neuroclastic ones O Is a socially constructed illness with the medical model of AD too focused on pathologizing populations over age 65 O Results from amyloid plaques and tangles on the brain
