Parkinson’s disease is one of the common diseases that plague elderly patients, but many older people do not know enough about this disease. Parkinson’s disease mostly develops between the ages of 50 and 70, but now cases of Parkinson’s disease in the 40s are also found in outpatient clinics. Many patients with Parkinson’s disease are not detected early symptoms in time, missing the best time for treatment, which seriously affects their quality of life, so how to detect Parkinson’s disease early? What are the early symptoms of Parkinson’s disease? Through investigation, Parkinson’s disease Braak pathological staging is divided into pre-motor and motor phase, if it can be detected in the pre-motor phase and intervention treatment, can greatly delay the progress of Parkinson’s disease. The main manifestation of Parkinson’s disease in the pre-motor phase is hyposmia, which is commonly known as reduced ability of the nose to smell. In addition, there is also emotional indifference, poor mood, lack of interest in things that used to be of interest, poor sleep quality, low activity, back pain, back and leg pain, constipation, difficulty urinating and salivation, etc. Of course, these symptoms may not all be present, but as long as several of them are present, attention should be drawn to them. If there is involuntary tremor of the hands, head or mouth at rest, muscle stiffness, tremor of one side of the arms and legs, or slow movement of one side of the limbs, smaller movements, reduced swing of one side of the arms when walking, etc., this may be in the motor phase of Parkinson’s disease, which is the easiest time to detect and cause patients to suspect, and thus go to the hospital. Therefore, if middle-aged or elderly people develop the above symptoms, they should go to the neurology department of the hospital to receive diagnosis and treatment in time to avoid delaying the treatment. When the disease reaches a certain level, patients with Parkinson’s disease will walk and posture differently from normal people, such as the pace gradually becomes smaller and slower, becoming difficult to start, once started, it is not easy to stop, called “panic gait”, due to the stiffness of the limbs, easy to fall. If the above situation occurs, it is more important to pay attention to it and go to the hospital for treatment in time.
