What causes the degeneration of brain tissue in CBD?
Unfortunately, the cause of CBD is entirely unknown. There is currently no strong evidence to suggest CBD is an inherited disease, and no other risk factors, such as toxins or infections, have been identified. Studies of brain tissue of individuals with CBD show certain characteristic cell changes. Similar, although not identical, changes are observed in two other neurodegenerative diseases, Pick’s disease and progressive supranuclear palsy. These changes, involving a brain protein called tau, have provided researchers some initial clues in their search for the causes of CBD.
