Alzheimer's disease (AD) is the commonest form of dementia, estimated to affect 37 million people worldwide. Currently there is nothing to halt the progression of AD – treatment focuses largely on slowing the development of symptoms. More recently disease-modifying interventions, such as immunotherapy, have been investigated as their aim is to halt or even reverse symptoms by removing β-amyloid (Aβ) pathology. This paper assesses the developments made in this particular field, offers critical appraisal of important papers and assesses the viability of this potential form of treatment.
