Parkinson's Disease [Parts 1 & 2] | 4 Cardinal Signs & Detailed Mechanism with Basal Nuclei

The video provides a comprehensive overview of Parkinson's disease, focusing on its cardinal signs, causes, and the role of the basal nuclei in movement. It explains the TRAP symptoms and how dopamine modulates the direct and indirect pathways in the brain. The video also delves into the mechanisms of Parkinson's disease, highlighting the progressive degeneration of the substantia nigra and its impact on movement, leading to hypokinesis.
