Alzheimer's disease is significantly affected by cerebral blood flow (CBF). Reduced CBF is a hallmark of the disease and contributes to its progression. Step 1: In Alzheimer's, there is a decline in the brain's ability to regulate blood flow, leading to hypoperfusion (reduced blood flow) in certain brain regions, particularly those involved in memory and cognition. Step 2: This reduced blood flow means that brain cells, especially neurons, receive less oxygen and glucose, which are essential for their function and survival. Step 3: The lack of adequate nutrients and oxygen can exacerbate the damage caused by the hallmark amyloid plaques and tau tangles of Alzheimer's, leading to neuronal dysfunction and death. Step 4: This impaired CBF is thought to contribute to the cognitive decline, memory loss, and other symptoms experienced by individuals with Alzheimer's disease. That's 3 done, 2 left today.
