Parkinson's disease is a brain condition that develops slowly over time. It happens when the brain loses cells in an area called the substantia nigra, which makes an important chemical called dopamine. Dopamine helps control movement, memory, and feelings of pleasure.
When these dopamine-producing cells decrease, symptoms like tremors, slow movements, and balance problems begin to appear. While Parkinson's can be treated to help manage symptoms, there is currently no cure. Though the condition becomes more challenging over time, it's important to know that people with Parkinson's generally have similar life spans to those without the condition.
