Parkinson’s disease is a degenerative disease of the nervous system and is one of the most common diseases afflicting the elderly. The prevalence of Parkinson’s disease is generally considered to be 0.3%, and 1% in people older than 60 years. China is the high incidence of Parkinson’s disease in the world, it is estimated that the number of people with Parkinson’s disease in China is about 2 million, but most Parkinson’s patients have a low awareness of the disease, many Parkinson’s patients due to failure to detect the early symptoms in time, the disease is not effectively controlled, and many patients diagnosed with Parkinson’s disease is already in the late stages, missed the best time for treatment. Central Hospital neurologist Wang Cui reminds you that Parkinson’s is a common disease of middle-aged and elderly people, the performance varies, the light may only be manifested as a perceptible tremor, the heavy can be manifested in the end stage of the disease as a serious disability, affecting the patient’s daily life, can not take care of their own lives, but also bring a heavy burden on the family. Therefore, it is important to understand the symptoms of Parkinson’s disease. What are the symptoms of Parkinson’s disease? The onset of Parkinson’s disease is slow, early symptoms are not very obvious, and there are individual differences, generally divided into the following five cases: 1, static tremor. Tremor is often the earliest manifestation of the onset of the disease, the typical frequency of the tremor is 4-6Hz, mainly in the distal limbs, the tremor in the hands is called “rubbing pills-like” movements, the tremor in the head area mainly occurs in the lips, jaw and jaw joints. The tremor increases in response to emotional changes. In general, Parkinson’s patients with tremor as their first symptom have a slow progression of the disease and a favorable prognosis. Not all Parkinson’s patients show tremor, according to statistics, 75% of the patients show tremor in the course of the disease. 2, muscle stiffness and flexion posture. In the early stage, it starts from the unilateral limb, and the patient feels the stiffness of joints and tightness of muscles. It can occur at the proximal end of the limb (such as neck, shoulder, hip) or distal end (such as ankle, wrist), and can often cause discomfort and pain. Therefore, shoulder pain caused by myasthenia gravis is often the first symptom of Parkinson’s disease, and it is often referred to orthopedics and pain medicine because of the pain, and it is often misdiagnosed as arthritis and synovitis. When the facial muscles are affected, there will be a decrease in expression, and we often refer to the “mask face”; muscle ankylosis affecting the trunk, limbs and knee joints will show a posture deformity of flexion. 3.Motor retardation. Parkinson’s disease is the most characteristic manifestations, early patients manifested as the slowing of daily activities, slow movement and slow reaction. Often, fine activities are impaired, such as tying shoelaces, buttoning and other movements are much slower than before, and even cannot be completed successfully. Writing also becomes progressively more difficult, with a curved handwriting that becomes smaller and smaller, known as “micrographia”. When walking, it is difficult to start, and once you start walking, your body leans forward, your steps are small and get faster and faster, and you can’t stop in time, i.e. “panic gait”. When walking, the coordinated swing of the upper limbs on the affected side is reduced or even disappeared; it is difficult to turn around, so that it is necessary to use several consecutive small broken steps. 4. Loss of postural reflexes. This often occurs in the later stages of Parkinson’s disease and is accompanied by freezing of gait. Freezing is also the most common reason why Parkinson’s patients are prone to falls, which may lead to injuries, such as fractures in the trunk position. Parkinson’s patients have postural instability during complex movements, especially when there are symptoms of forward trunk flexion, panic gait to chase the center of gravity to prevent falls when walking; sitting down will sit directly on the chair because of the loss of postural reflexes, and so on. 5, non-motor symptoms. Although Parkinson’s disease is a movement disorder, but now more and more awareness of its non-motor symptoms, 88% of patients with non-motor symptoms, and even in 28% of patients, these non-motor symptoms itself or non-motor symptoms of fluctuations than the movement of the symptoms of the patient’s life. Non-motor symptoms include: decreased sense of smell, tiredness, anxiety, depression, leg pain, insomnia, dysuria, constipation, salivation, poor concentration, psychiatric symptoms, abnormal sweating, dementia, and more. It can be seen that non-motor symptoms can involve multiple systems of the patient’s body and have a huge impact on the patient. Loss of smell, constipation, shoulder pain and other non-motor symptoms can also be early symptoms of Parkinson’s disease, which can help the neurologist in the early stage of the patient’s symptoms. The above is the explanation of Parkinson’s disease motor symptoms and non-motor symptoms, I hope it will be helpful to you. For the symptoms of Parkinson’s disease in the elderly need to be detected early, if the above situation, we should pay attention to timely to the hospital for early diagnosis, early treatment, to prevent the progression of the disease, early recovery, early return to normal work and life.
