Alzheimer's and Parkinson's diseases are neurodegenerative disorders that affect millions worldwide. Alzheimer's primarily impairs memory and cognitive function, while Parkinson's disrupts motor skills. Both conditions share commonalities in the gradual loss of brain cells and proteins. While Alzheimer's targets memory-related regions, Parkinson's affects the dopamine-producing cells. Early detection is crucial for managing symptoms, but unfortunately, there is no cure for either disease. Ongoing research seeks to unravel their complexities and develop innovative treatments, offering hope for improved quality of life for those affected.
