As the number of people with Parkinson’s disease grows, Parkinson’s disease is gradually becoming more recognized, but again, due to the complexity of Parkinson’s disease, many people’s understanding of Parkinson’s disease stays on limb tremors, and when they see hand tremors, they think it is Parkinson’s disease, in fact, hand tremors are not necessarily Parkinson’s disease, in addition, motor slowing and body stiffness and inflexibility are also often overlooked in the early stages and mistaken for the disease of old age. Nowadays, after more and more in-depth research on Parkinson’s disease, it is found that there are many precursor symptoms that may exist before the appearance of symptoms such as limb tremors, stiffness and sluggishness, such as mental anxiety, depression and loss of sense of smell, etc. If Parkinson’s disease can be detected earlier, it can be treated and benefited earlier. Here are the 7 symptoms that need to be alerted to early Parkinson’s disease. Parkinson’s disease can be divided into five stages according to the progression of symptoms: Stage 1: unilateral lesions only, unilateral hand tremor, foot tremor or stiffness, walking is not as sharp as usual, holding things unstable; Stage 2: bilateral mild lesions, from unilateral lesions to bilateral, hands shake, even the whole body shake, stiffness aggravated, buttons, chopsticks and other daily activities become difficult, poor balance; Stage 3: bilateral lesions with early balance disorders. Difficulty in lifting legs, walking in small steps, easy to fall. Stage IV: severe lesions, often unconscious drooling, difficulty in swallowing, slow eating. Speech is slurred, expression is dull, face is expressionless, movement is difficult, and daily life is inseparable from family care; Stage V: Patients are confined to bed or wheelchair and cannot take care of themselves completely, some patients are only bedridden for a long time, cannot turn over by themselves after being bedridden, and cannot take care of themselves completely in daily life. Parkinson’s disease is a chronic progressive disease and the timing of surgery is particularly important. Surgery is most appropriate after the honeymoon period of medication and when motor complications arise, which means that surgery is best when the disease has progressed to “stage 3”. Careful selection of patients with Parkinson’s disease in the early stages of the disease who have just developed motor complications will help to maximize the long-term benefits of pacemaker therapy after a team of physicians has fully evaluated the pros and cons of the patient.
