A team of scientists in the UK has claimed to have found the reason behind brain cell death which leads to Alzheimer’s, offering hope for a future new line of drugs which could cure the disease. Alzheimer’s is the most common cause of dementia (decline of brain function, memory and thinking skills). 

It has a variety of complex causes, including the build-up of proteins called amyloid and tau in the brain (substances which create small structures called plaques and tangles), hindering brain function. There is also a loss of neurons - or brain cells - resulting in a breakdown of neural networks resulting in memory loss.
