We'll, that was fascinating. I didn't realize Alzheimer's patients lost their sense of smell. I truly doubt it enters in that way, especially since it seems to be predominantly based on age rather than outside factors. That said, any way to diagnose it early to try and slow or arrest its progression is good.
Diabetes drug 'significantly reverses memory loss' in mice with Alzheimer's. A drug developed for diabetes could be used to treat Alzheimer's after scientists found it 'significantly reversed memory loss' in mice through a triple method of action. This is the first time that a triple receptor drug has been used which acts in multiple ways to protect the brain from degeneration. It combines three growth factors. Problems with growth factor signalling have been shown to be impaired in the brains of Alzheimer's patients. Source 3g.
Anxiety: An early indicator of Alzheimer's disease? A new study suggests an association between elevated amyloid beta levels and the worsening of anxiety symptoms. The findings support the hypothesis that neuropsychiatric symptoms could represent the early manifestation of Alzheimer's disease in older adults. Source 7b.
Antibody removes Alzheimer's plaques, in mice. Plaques of a brain protein called amyloid beta are a characteristic sign of Alzheimer's disease. But nestled within the plaques are small amounts of another Alzheimer's protein: APOE. Now, researchers have shown that an antibody not only targets APOE for removal but sweeps away plaques in mice. The findings could lead to a way to halt the brain damage triggered by amyloid plaques while the disease is still in its early stages, perhaps before symptoms appear. Source 7c.
