1. Stiffness: Stiffness increases gradually, movements become slower and less, and it becomes more and more difficult to start. Stiffness combined with too little exercise may lead to muscle pain and fatigue.
Second, tremor: the first symptom is usually a static "twisting pill-like" tremor of 4-8 Hz in one hand. This tremor is most obvious when the limbs rest, weakens when the limbs move, and disappears when sleeping. Emotional tension or fatigue will aggravate the tremor. Tremors generally occur in the hands, the arms and legs are the most serious, and the order of symptoms is also the earliest in the hands, and the latest in the legs, jaws, tongue, forehead and eyelids, but the sound is not affected.
Third, in addition, some patients have early symptoms of Parkinson's disease, such as autonomic nervous dysfunction. The early symptoms of Parkinson's disease are greasy face, sweating, drooling, difficulty in defecation and orthostatic hypotension, as well as depression and dementia.
