Symptoms of Parkinson’s disease can vary at different stages as the disease progresses. They may also vary from patient to patient and cannot be generalized. In general, the disease gets progressively worse over time. Parkinson’s disease is divided into several main stages: initial, intermediate, and late stages. Initial symptoms include tremor, stiffness, and slow movements. Uncontrolled tremors in the affected hands and legs occur continuously, especially at rest. The tremor starts on one side of the hand or leg and then slowly progresses to the same side of the body. The muscles of the arms and legs become stiff, and when the patient straightens or flexes the arms or legs, he or she notices a greater resistance in the area, making it difficult to move as if turning a gear. This stiffness can lead to muscle soreness or an inability to straighten the body. The symptoms of bradykinesia include difficulty in writing, smaller and smaller fonts, prolonged sitting without changing sitting position, difficulty in starting and stopping, and lack of facial expression. In the middle stage, the symptoms include: the development from one side of the body to both sides; the phenomenon of “switching off” of the medication, in which the medication fails to have an effect during two doses and the ability to interact is lost, as if the power is turned off; walking and posture are affected, the feet cannot be lifted when walking, and walking drags on the ground; loss of balance, easy to fall, and lack of swinging of the hands when walking. Lack of swing, so the patient used to start, that is, to rush forward with sharp broken steps to maintain a stable center of gravity; the speed of turning the body becomes slower, but the patient can still maintain the ability to take care of themselves. The main symptoms in the late stage are: further deterioration of the disease, walking is obviously affected, or even the complete loss of mobility; the patient loses the ability to take care of himself and needs the care of others; difficulty in speaking and swallowing; some “involuntary movements” of the body, i.e., “anomia The patient has difficulty in speaking and swallowing; some “involuntary movements” of the body, i.e. “anomia”; distortion of the joints of the limbs. In addition to the above major symptoms, Parkinson’s disease patients may also have some other symptoms: speech impairment, the patient’s language ability is affected by the low volume, slow, difficult pronunciation and other problems; swallowing difficulties, eating and swallowing difficulties, drooling, choking easily when drinking water, etc.; excessive sebum production, such as greasy surface; joint swelling; weight loss; severe constipation, urinary incontinence; impaired sexual ability; frequent dozing ; cramps and muscle pain; emotional depression; frequent awakening during night sleep. The main methods of treatment for Parkinson’s disease are currently drugs and minimally invasive brain pacemaker surgery. Accurate staging and positioning according to the patient’s clinical manifestations, combined with comprehensive treatment such as diet and rehabilitation exercises, can greatly slow down the symptoms, effectively alleviate the progression of the deterioration of the disease, and leave the patient in a relatively comfortable state of life.
