A ground-breaking new book from the bestselling author Dr David Perlmutter that will transform our understanding and treatment of degenerative brain diseases that are afflicting people around the world. In recent years microglia cells housed in the brain have been identified as playing a key role in a host of neurodegenerative diseases such as Alzheimer's, Parkinson's, Long Covid, and MS amongst others. When operating optimally, these cells support healthy brain function. However, when they go rogue, they cause inflammation in the brain, contributing to cell death and devastating neurological conditions. Current drug treatments mostly mask symptoms rather than cure and the statistics are grim: worldwide, 55 million people suffer from Alzheimer's, 10 million people have been diagnosed with Parkinson's, and serious neurological disorders are on a rapid rise. And the good news? By following the lifestyle protocol that Dr David Perlmutter presents in the book based on supporting microglial cells to work in harmony with the body, people can become 'architects of their cognitive destiny'. The program is accessible to all with practical diet, lifestyle and exercise advice, Brain Defenders will help us start to win the war against the scourge of neurodegenerative diseases.
