<2> Alzheimer’s may begin with a silent drop in brain blood flow
<3> The Vascular Connection to Alzheimer’s
Research has long established that Alzheimer’s disease is a multifaceted condition, driven by both amyloid plaques and neurofibrillary tangles in the brain. However, a growing body of evidence suggests that subtle changes in brain blood flow and oxygen use may be an early warning sign of the disease. < href='https://www.who.int/news-room/fact-sheets/detail/alzheimers-disease' target='_blank'>According to the World Health Organization, Alzheimer’s is a leading cause of dementia worldwide, affecting millions of people.
<3> The Role of Brain Blood Flow in Alzheimer’s
Studies have shown that individuals with Alzheimer’s tend to experience a decline in brain blood flow, which can lead to a reduction in oxygen delivery to the brain. This, in turn, can cause damage to brain cells and contribute to the formation of amyloid plaques. < href='https://www.nature.com/articles/s41598-021-89538-4' target='_blank'>A study published in Nature found that changes in brain blood flow were closely linked to the development of amyloid plaques in individuals with Alzheimer’s
