Many people with Parkinson’s disease do not understand the stages of their disease and are blinded by the medication they see. Neurologists have subdivided the course of Parkinson’s disease into the following stages: Stage I: Unilateral lesions only Unilateral hand tremors, foot tremors or stiffness, walking less than usual, and unsteadiness in holding things. Because the impact on life is not very big, it is often easy to be ignored by patients and their families. If treated in time during this period, patients have great hope for complete control of their symptoms! Stage II: Bilateral mild lesions From unilateral to bilateral lesions, shaking of the hands or even the whole body, increased stiffness, daily activities such as buttoning and holding chopsticks become difficult, walking with difficulty and poor balance. Stage III: Bilateral lesions with early balance disorder Difficulty in lifting legs, legs like heavy sandbags, walking with small steps, dragging steps and leaning forward, easy to fall. The patient is unable to hold the bowl steadily during meals, and needs help from family members for daily activities such as turning over at night and bathing. Stage IV: severe lesions requiring a lot of help. Speech is slurred, and the voice is very small, so that people have to come closer to hear clearly. Dull expression, mask face, and increasingly stiff facial muscles, no expression on the face, little blinking, and reduced eye movements. Movement is difficult, and daily life cannot be done without the care of family members. Stage V: Completely unable to take care of oneself in daily life Confined to bed or wheelchair, completely unable to take care of oneself in daily life. Confined to bed or wheelchair unless assisted by family members. Some patients are only bed-ridden for a long time, unable to stand on their own after sitting down, unable to turn over on their own after being bed-ridden, and completely unable to take care of themselves in daily life. It is important to note that active treatment is required from the beginning of the disease, especially for patients with stage 1-2, where the disease progresses relatively slowly and is a golden period in terms of disease development, and the medication and treatment at this time should be active and regular, and if not actively treated the disease will aggravate sharply. After stage II, if the duration of the drug effect is shortened and the control effect is poor, this is the time to consider the method of deep brain electrical stimulation surgery to treat the disease. The quality of life of patients will also be much better.
