Parkinson's Disease is a progressive and lifelong disease of the neurological system that predominantly affects movement. The most common recognizable symptoms include tremors, especially at rest, and bradykinesia (slow movement). Individuals affected by Parkinson's Disease generally present muscle rigidity and stiffness, making it difficult to move certain body parts. Gradually, individuals may also develop postural instability and thus experience increased difficulty in maintaining balance and an increased risk for falls. Other motor symptoms include a shuffling walk, difficulty performing fine motor activities such as buttoning a shirt or writing, and a decreased range of motion. Generally, there are non-motor symptoms such as depression, anxiety, sleep disturbances, and cognitive changes, which include problems with memory and concentration. As the disease progresses, these symptoms become more pronounced, significantly affecting everyday life and independence.
