There are many variations of dementia syndrome but there are certain causes that are more common. These are: Alzheimer’s: Scientists know that during Alzheimer’s two abnormal proteins build in the brain. They form clumps called either ‘plaques’ or ‘tangles’. These plaques and tangles interfere with how brain cells work and communicate with each other. The plaques are usually first seen in the area of the brain that makes new memories. A lot of research is focused on finding ways to stop these proteins in their tracks and protect brain cells from harm.

3. People suffering from dementia often have problems processing information; this is due to chemical reactions that usually take place in the brain, no longer happening due to the damage of the neurons. Therefore the neurons are not able to produce or transmit important chemicals which are required for the person to function properly. Some of these chemicals are:
Dopamine: This chemical controls body movements. Lack of dopamine means you will no longer be able to control your movements very well. Dopamine also controls the transportation of information
