Condition: Alzheimer's Disease (AD) · Sponsor: Imperial College London
Alzheimer's disease is a degenerative condition affecting the brain and is the most frequent form of dementia in older adults. Dementia is currently a major healthcare issue in the UK, affecting approximately a million people. The progression of the disease varies between individuals and the early stages may be characterised by only minimal changes in memory and thinking. These changes could remain undetected as the symptoms may be mistakenly regarded as normal age-related forgetfulness. However, dementia is not part of the normal ageing process. The disease process is now known to start at least 20 years prior to the emergence of symptoms. A protein called amyloid starts to deposit in the brain, forming clumps referred to as 'plaques'. Another protein called tau sticks to other tau molecules inside the brain cell and forms structures called 'tangles'. These changes cause damage to the brain cells, disrupting their normal functioning, leading to inflammation and ultimately destruction of the brain cells. So far, there is no cure for Alzheimer's disease, but by better understanding the changes that occur over time in the brain, scientists can find ways of detecting and therefore diagnosing and treating the disease earlier. One way in which scientists learn about how a disease develops, is by following people unaffected by the condition over an extended period of time. The same tests and sample collections are repeated to monitor any clinical changes. These are known as longi…
