The video explains prion proteins, which are misfolded proteins that aggregate and cause diseases like Alzheimer's, Parkinson's, and kuru. These aggregates disrupt neuron function, leading to brain deterioration and death. The video uses analogies to clarify the misfolding and aggregation process, emphasizing the critical role of prion propagation in disease onset.
