Tremors are very obvious signs, whether they occur in the hands, feet or head or other parts of the body, and can easily be detected as abnormal. When tremors occur, people generally seek active medical attention. Of course, Parkinson’s patients may also have tremors in their hands or legs and feet, but the presence of tremors does not necessarily mean Parkinson’s disease; idiopathic tremors can also have tremors. Parkinson’s disease and idiopathic tremor both belong to brain neurological dysfunction diseases, both diseases will have trembling symptoms, but trembling is the only symptom of idiopathic shock, while Parkinson’s disease has muscle stiffness, motor retardation, abnormal posture and gait, in addition to limb trembling. Now some Parkinson’s disease early or during the course of the disease are not tremor symptoms, but other symptoms, often by the patient and its surrounding to ignore, many diagnosed and then treated when it is too late. The following are the most easily ignored symptoms of Parkinson’s disease summarized by Professor Wang, and these symptoms should also be actively sought after. 1. Diminished or absent sense of smell is an important piece of information. Some studies found that Parkinson’s patients basically have abnormal sense of smell, about 50% of Parkinson’s patients have no sense of smell at all, 35% of them have severe olfactory impairment, and some of them have mild to moderate impairment. Therefore, if you find that middle-aged or elderly people have hyposmia, you can go to the hospital for examination and ask a neurologist for consultation to help make a clear diagnosis after observing whether there are other symptoms. 2. Slow movement, this is the most easily ignored symptom, especially in older people, because it is a common symptom in the elderly, but if you find that the movement of buttoning, putting on socks, tying carrying, etc. has become significantly slower, sometimes you feel that one side of the arm is always a little bit uncomfortable, a little bit stiff and less flexible. It is also important to pay attention to the fact that writing is getting smaller and smaller. Older people have more or less certain cervical spine problems, which are often misdiagnosed as cervical spondylosis, and in fact some of the patients are Parkinson’s disease. 3, the onset of the elderly expressionless face, non-blinking and double gaze, or the appearance of depression, unhappiness or fear, as well as fist punching, kicking, yelling and other violent movements during sleep, may also be a manifestation of Parkinson’s disease. 4. When walking, you find that the swing of one arm is less than the swing of the other, or that one foot scrapes the ground while the other is normal. Or it may be difficult to take the first step and need to be pulled in order to walk, or it may be difficult to walk very fast, unable to brake, unable to turn around for half a day, etc. Parkinson’s disease mostly occurs in middle and old age. If you find that an elderly person has the above symptoms, you should register with a neurologist, who will give you the correct diagnosis.
