The main symptoms of Parkinson's disease are divided into two major categories: motor symptoms and non-motor symptoms. The motor symptoms include bradykinesia and hypokinesia, specifically characterized by slow movement speed and reduced amplitude. In daily life, this results in clumsiness with actions such as difficulty standing up, small arm swings while walking, or even no swinging at all, a lack of facial expressions, and progressively smaller handwriting. The second type is resting tremor, which includes pill-rolling movements along with muscle rigidity and postural and gait imbalances, such as a panicked gait or taking very small steps that accelerate and become faster without the ability to stop or turn promptly. Non-motor symptoms include issues such as olfactory dysfunction, sleep disturbances, constipation, and depression.
