Lecture
This lecture provides a comprehensive overview of Parkinson's disease, detailing its historical context, clinical symptoms, and the underlying neurobiology. The instructor begins by discussing the initial clinical description by James Parkinson and the subsequent identification of the disease's pathology, particularly the role of the substantia nigra and Lewy bodies. The lecture highlights the four cardinal motor symptoms: bradykinesia, resting tremor, rigidity, and postural instability, along with various non-motor symptoms such as depression and cognitive decline. The challenges in diagnosing Parkinson's disease are emphasized, noting the reliance on clinical features and the absence of definitive tests. The instructor also discusses current treatment options, including dopamine replacement therapy and deep brain stimulation, while addressing the limitations of these therapies in managing both motor and non-motor symptoms. The lecture concludes with a discussion on the future of Parkinson's research, focusing on the need for early biomarkers and disease-modifying therapies to improve patient outcomes.
