The Structure of the Brain
The brain is the body's control center, and it's made up of billions of tiny cells called neurons.
narration
What Is a Neuron?
A neuron is a special kind of cell in our brain and nervous system. It’s like a tiny messenger that carries information all around our body. When we learn, the connections between neurons are strengthened, and this is believed to be the basis for memory and learning.
narration
What Is Alzheimer's?
Alzheimer’s disease is a serious condition that affects the brain.
One of the ways it does damage is by killing neurons, causing:
Difficulty WithCoordination
Memory Loss

Theories of Alzheimer's
Scientists still don’t know exactly what causes Alzheimer’s disease. Today, there are a few leading theories.
Tau Tangle Theory
Inflammation Theory
Amyloid Plaque Theory
Infectious Theory
narration
In a healthy brain signals travel freely between neurons.
Amyloid Plaque Theory
With Alzheimer's, signals are blocked by amyloid plaques from outside the neuron.
As a result, neurons starve and die, affecting brain function.

Tau Tangle Theory
Instead of the buildup of amyloid plaques outside the neuron, the Tau Tangle Theory states that it is the build up of tau tangles inside the neurons that lead to their death.
Tau tangles form inside neurons and disrupt brain signals. As a result, neurons starve and die, leading to problems like memory loss and difficulty with coordination.

Inflammation Theory
Lack of Exercise
Infections
The inflammation theory is a relatively recent theory. It says that it is not just the blockages in our brains that matter, but it is about our ability to heal too. People with Alzheimer’s disease have higher levels of inflammation in their brains. Inflammation can damage brain cells and lead to problems with memory and thinking.
Injury
Unhealthy Diet
narration
Inflammation Theory
Microglial cells are janitors of the brain, they reduce inflammation by clearing out plaques
and toxins.
With Alzheimer's, microglial cells become inactive,
causing inflammation.

Infectious Theory
Stress
Infection
Our bodies are filled with bacteria, viruses, and fungi, and these microbes may cause an inflammatory response. Microbes can enter the brain and lay dormant for decades, but once activated, they cause an infection that makes plaques more likely to accumulate. This theory does not claim that Alzheimer's disease is the result of an infection, but it does represent a new direction of research.

Imagine if a telephone line got cut or broken. The messages would not be able to get through. This is what happens when neurons die or get damaged: The brain can’t communicate properly.
Imagine a house is on fire, the fire department comes to put out the fire, but the fire trucks and the water they use to put out the fire also damages some of the house, that's similar to what happens in the brain, when there's an injury or an infection, the body sends inflammatory cells to fight it, but these cells can also cause damage to the neurons.
