What Triggers Neurodegeneration in Dementia?

What actually causes the brain to deteriorate in dementia? Scientists have long been searching for answers. While we know that misfolded proteins—like beta-amyloid plaques and tau tangles—disrupt brain cell function, the true triggers behind these changes remain a mystery. Are genetics to blame? Could environment or lifestyle play a role? This short video breaks down what we know so far and where current research is heading in the quest to understand, treat, and prevent neurodegeneration.
