What are the early signs of Parkinson’s disease? Chen Haibo said that Parkinson’s disease mainly affects a person’s ability to move around, called motor symptoms. These symptoms are the main basis for our diagnosis of Parkinson’s disease. The typical motor symptoms of Parkinson’s disease include four aspects, such as slow movement, tremor, muscle tonus and postural balance disorder, etc. A person who has symptoms of two aspects should consider the possibility of Parkinson’s disease. Slow movement, early manifestations of slow movement, walking can not walk fast, can not keep up with peers. Due to slow facial movements, facial expressions become dull, and smiling when happy is not natural. Some patients feel that they can’t lift their feet when walking and feel weak. The upper limb of the affected side does not swing when walking, as if the arm is tied up. Patients often have reduced activity and sit at home without moving. Tremor. Tremor in Parkinson’s disease is called resting tremor, which means that the tremor occurs in the limb when it is relaxed and quiet, and decreases or disappears when it is active. Tremor is the first symptom of Parkinson’s disease in about 50% of people with Parkinson’s disease and is one of the main symptoms of Parkinson’s disease. Tremor is characterized by tremors of large rhythmic amplitude. Early tremor begins in one hand and gradually extends to the other limbs. The tremor worsens when angry and decreases when emotionally stable, and it can be completely terminated during sleep. Although strong willful effort can temporarily suppress the tremor, it is short-lived and tends to worsen afterwards Myotonicity, which is an increase in muscle tension. The patient himself often feels that the muscles are stiff and cannot be relaxed, as if they are tied up. There is a noticeable resistance when pulling the patient’s limb and it appears stiff. Myotonicity in elderly patients can cause pain in the joints and is sometimes misdiagnosed as arthrosis for a long time. Sometimes hip pain can occur during standing and walking, which is due to increased myotonia causing obstruction of blood supply to the nutrient vessels of the joint and decreased muscle strength, and compression of the joint by weight. Some patients feel weak due to increased muscle tone in the lower limbs. When symptoms are limited to one limb, it is often misdiagnosed as cerebrovascular disease. Postural balance disorders, due to muscle tonus, patients develop a specific posture with forward head tilt, prone trunk flexion, elbow flexion in the upper extremity, and slight hip and knee flexion in the lower extremity. Due to the imbalance of muscle tone on both sides of the trunk, patients may develop trunk scoliosis. Due to the imbalance of muscle tone on both sides of the trunk, patients may have scoliosis. Patients with trunk ankylosis and postural balance disorders often fall on the chair when trying to sit down. Chen Haibo suggests that patients with these symptoms should see a doctor as soon as possible for early diagnosis and treatment.
