There are two abnormal physiological structures, called “plaques and tangles” that are causing the damage to the brain, which manifests as Alzheimer’s disease.
Plaques are deposits of a protein called “Beta- Amyloid”. When these plaques are formed together they create a toxic effect on the neurons in the brain and disrupt the communication between different brain cells.
Tangles are twisted fibres of a different protein, which is called “tau”. They build up inside cells, and interfere with the brain’s transport system.
All people develop plaques and tangles in their brain as they age, but for people who suffer from Alzheimer’s disease, these plaques and tangles develop far faster and in particular areas of the brain that are important for memory and cognitive abilities.
The plaques and tangles block communication between versace cells and are interrupting processes that allow nerve cells to build new connections and grow.
