ALZHEIMER’S DISEASE
Alzheimer’s disease is a progressive, neurodegenerative disease which is
caused by physiological changes to the brain. It changes the delicate
organisation of the nerve cells in the brain by creating the gradual spread of
sticky plaques and clumps of tangled fibres. As brain cells stop communicating
with each other, they atrophy, causing memory and reasoning to fade. Tangles and
plaques first appear in the entorhinal cortex, an essential memory-processing
centre needed for creating memories and retrieving old ones. This does not
affect detailed complex memories, but rather the simple recollections of facts
that allow us to function socially, such as birthdays and lunch dates. Over time
they move higher, invading the hippocampus, that part of the brain that forms
complex memories of events or objects. These kinds of memories are, of
necessity, more detailed and involve longer recollection
