What are the symptoms of Parkinson’s? In addition to trembling, Parkinson’s disease symptoms include stiffness, slow movement, abnormal gait and balance disorders, etc. Parkinson’s disease patients move slowly, not just half a beat slower than normal people, but to the point that their movements are as slow as “slow motion” in a movie. For example, it takes a normal person only a few seconds to raise their hand or make a fist, but a person with Parkinson’s disease in the middle to late stages of the disease may take one to three minutes to do so, which is very slow and awkward, especially when it comes to fine motor movements. At the same time, Parkinson’s disease patients will blink slower, medically known as “transient eye movement reduction”, normal people blink dozens of times a minute, Parkinson’s disease patients may only blink a few times a minute, so the “eye” is not normal. In addition, Parkinson’s disease patients with facial expression stagnant, mute, feel always staring at people, in fact, is unconscious. Some people with Parkinson’s disease can’t close their mouths or even drool. Hazards of reduced transient eye movements Many Parkinson’s patients often complain of decreased vision, reading difficulties, dry eyes, etc. The earliest symptoms of dry eyes that are prone to occur are mainly due to the reduced function of the muscles responsible for eye movements, which makes the movements including blinking reduced, and these movements can precisely make the tears wet the surface of the eyeballs, keep the cornea glossy, and remove the dust and bacteria inside the eye, so Parkinson’s patients in the early stages of are prone to symptoms such as dry eyes and eye irritation. Parkinson’s disease is a common neurodegenerative diseases, the elderly are common, Parkinson’s disease on the elderly harm, second only to tumors and cardiovascular disease, and is now clearly showing a younger development trend. According to statistics, about 1.7% of the elderly population over 65 years old in China suffer from Parkinson’s disease. At present, the total number of Parkinson’s disease patients in China is more than 2 million, accounting for about half of the global number of such patients, and Parkinson’s disease has become the “third killer” of middle-aged and elderly people. Understanding the early symptoms of Parkinson’s disease is conducive to early detection and treatment. Earlier detection and treatment will help to control the disease and improve the quality of life of patients.
