Alzheimer's disease (AD) is a neurodegenerative disease with a slow onset and worsening over time.
NEURON
"Memory is actually reactivating the once activated connections between brain regions."
The brain and spinal cord are made up of neurons.
Neurons have different functions, such as controlling movement, processing sensory information and making decisions.
Cells in the brain and spinal cord don't regenerate.
Excessive damage can be devastating and irreversible.
Neurodegenerative diseases are caused by the loss of neurons or their myelin sheath.
