Parkinson's disease is a neurodegenerative disorder that affects movement control. It is characterized by symptoms such as tremors, stiffness, slow movements, and difficulty with balance and coordination. The disease is caused by the loss of dopamine-producing cells in the brain, leading to a decrease in dopamine levels, which affects the communication between nerve cells and muscle control. Research in Parkinson's disease focuses on understanding the underlying causes of the disease, developing new treatments to manage symptoms and slow disease progression, and improving the quality of life for individuals living with the condition. This research includes studying the genetic and environmental factors that contribute to the development of Parkinson's disease, investigating potential biomarkers for early diagnosis, and exploring new therapies such as deep brain stimulation and gene therapy. Additionally, research is also being conducted on the role of inflammation, oxidative stress, and mitochondrial dysfunction in the development of Parkinson's disease.
