Alzheimer's is caused by the loss of what?

Answer 1

Alzheimer’s happens when brain cells start to die. The connections between brain cells also break down. This makes it more difficult for the brain to function properly. Over time, parts of the brain shrink, especially those involved in memory and thinking.

You can think of it like the brain’s wiring is getting damaged. The brain gradually forgets how to perform tasks. That’s why people with Alzheimer’s feel confused and forget things easily. It’s not just normal aging—it’s a disease that changes how the brain works.

Answer 2

Alzheimer's disease is primarily caused by the loss of neurons and synapses in the brain, leading to cognitive decline and memory loss. This neurodegeneration is associated with the accumulation of amyloid plaques and tau tangles, which disrupt communication between brain cells. Additionally, inflammation and vascular factors may also contribute to the progression of the disease. The exact cause remains complex and multifactorial, involving genetic, environmental, and lifestyle factors.
