Who’s who in Alzheimer’s? A medical fieldwork guide December 7, 2018 Alzheimer’s is a physical disease that affects the brain and is the most common type of dementia in the UK. Over time, the disease causes proteins to build up in the brain and form structures called’plaques’ and’tangles’. These proteins lead to the loss of connections between nerve cells, eventually resulting in the death of the cells and loss of brain tissue. Additionally, Alzheimer’s sufferers also have a shortage of vital chemicals which help to transmit signals around the brain, meaning that the signals aren’t transmitted effectively.
