If the underlying illness is treated or managed, symptoms of MCI often disappear and cause no further problems. But in some cases, people with MCI are at increased risk of going on to develop dementia, which is usually caused by Alzheimer's disease. There are many dementia research projects and clinical trials going on around the world, many of which are based in the UK.
