Parkinson’s disease is a degenerative disease of the nervous system and is one of the common diseases that afflict the elderly. The incidence of Parkinson’s disease is generally considered to be 0.3%, and 1% in people older than 60 years old. Many patients are diagnosed in the middle and late stages, missing the best time for treatment. Parkinson’s is a common disease in middle-aged and elderly people, and its manifestations vary, from a perceptible tremor in mild cases to a severe disability at the end of the disease, which affects the patient’s daily life and prevents him/her from taking care of himself/herself, and brings a heavy burden to the family. Therefore, it is important to understand the symptoms of Parkinson’s disease. So what are the symptoms of Parkinson’s disease? Parkinson’s disease starts slowly, the early symptoms are not very obvious, and there are individual differences, generally divided into the following five cases: 1, resting tremor Tremor is often the earliest manifestation of the onset, the typical frequency of tremor is 4-6Hz, mainly in the distal limbs, the tremor in the hand is called “pill-like” action, in the head area The tremor in the head region occurs mainly in the lip, chin and jaw joints. The tremor may increase in response to emotional changes. In general, Parkinson’s patients with tremor as their first symptom have a good prognosis for a slow progression of the disease. Not all Parkinson’s patients exhibit tremor, and it is estimated that 75% of patients exhibit tremor during the course of the disease. 2. Muscle stiffness and flexion posture The early stage starts with a unilateral limb, where the patient feels stiffness in the joints and tightness in the muscles. It can occur at the proximal end of the limb (e.g. neck, shoulder, hip) or distal end (e.g. ankle, wrist) and often causes discomfort and pain. Therefore, shoulder pain caused by muscle tightness is often the first symptom of Parkinson’s disease, and is often referred to orthopedic and pain departments for pain, and is also often misdiagnosed as arthritis and synovitis. When the facial muscles are affected, the expression will be reduced, and we often mention the “mask face”; muscle ankylosis affecting the trunk, limbs and knee joints will show the postural deformity of flexion. 3, motor retardation is the most characteristic manifestation of Parkinson’s disease, early patients show the slowdown of daily activities, slow movement and slow response. Often, fine activities are impaired, such as tying shoelaces, buttoning and other movements are much slower than before, and even cannot be completed successfully. When walking, it is difficult to start, and once you start walking, your body leans forward and your pace becomes smaller and faster, and you cannot stop walking in time, which is called “panic gait”. The swing of the affected upper limb decreases or even disappears; it is difficult to turn around, so that it is possible only with several consecutive small broken steps. This condition often occurs in the later stages of Parkinson’s disease and is accompanied by a freezing of gait. Freezing is also the most common reason why Parkinson’s patients are prone to falls and may lead to injuries, such as fractures of the trunk position. Parkinson’s patients have postural instability during complex movements, especially when there are symptoms of forward trunk flexion, walking with panic gait to chase the center of gravity to prevent falls; sitting down with loss of postural reflexes and sitting directly on the chair, etc. 5. Non-motor symptoms Although Parkinson’s disease is a movement disorder, there is a growing awareness of its non-motor symptoms. 88% of patients have non-motor symptoms, and even in 28% of patients these non-motor symptoms themselves or fluctuations in non-motor symptoms affect patients’ lives more than motor symptoms. Non-motor symptoms include: decreased sense of smell, feelings of exertion, anxiety, depression, leg pain, insomnia, urinary frequency and urgency, constipation, salivation, inattention, psychiatric symptoms, abnormal sweating, dementia, etc. It can be seen that non-motor symptoms can involve many systems of the patient’s body and have a huge impact on the patient. The loss of smell, constipation, shoulder pain and other non-motor symptoms also as early symptoms of Parkinson’s patients can help neurologists early in the patient’s presentation. For the symptoms of Parkinson’s disease in the elderly need to be detected early, if the above situation, to draw attention to the hospital in a timely manner for early diagnosis, early treatment, to prevent the progress of the disease, early recovery, early return to normal work life.
