Fresh insights into the spread of damaging proteins that build up in the brains of people with Alzheimer’s disease could hold the key to stopping the condition progressing, a study says.
Researchers have discovered that synapses, which send essential signals through the brain, are also transporting toxic proteins known as tau around the brain.
Large clumps of the protein tau – called tangles – form in brain cells and are one of the defining features of Alzheimer’s disease. As these tangles spread through the brain during the disease there is a decline in brain function.
