Parkinson’s disease is more common among the elderly, so it has become a problem for many middle-aged and elderly people. Parkinson’s disease is a kind of sudden disease and characterized by slow development, a little lack of attention to treatment will aggravate the development of the disease, and even death. First of all, we need to confirm the diagnosis of Parkinson’s disease, but how to confirm the diagnosis of Parkinson’s disease? Parkinson’s diagnosis is a strong basis for the treatment of Parkinson’s, only accurate diagnosis of Parkinson’s disease, in order to develop a scientific treatment program. 1, the difference between the diagnosis: often mistaken for Alzheimer’s disease: Parkinson’s patients in 30% -40% of patients, the early does not appear hand tremor. Only manifested as slow movements, inflexible hands and feet, stiff limbs, facial expressionlessness, etc., often mistakenly said to be “dementia”, “dementia”, etc., due to these Parkinson’s disease patients will be accompanied by nervousness, worry, fidgeting, insomnia, etc., the so-called “Parkinson’s disease”, “Parkinson’s disease” is often mistakenly said to be “dementia”. Because these Parkinson’s disease patients will be accompanied by nervousness, worry, restlessness, insomnia and other so-called “non-motor symptoms of Parkinson’s disease” in the early stage of the disease, they are sometimes treated as Alzheimer’s disease by the doctors and their families. 2, and other diseases to identify: Parkinson’s disease early symptoms are not very obvious, often confused with other diseases. The diagnosis of Parkinson’s disease is differentiated from hysterical, nervous and senile tremor. At the same time, also exclude encephalitis, cerebrovascular disease, poisoning, trauma and other triggers of Parkinson’s disease syndrome. 3, symptomatic diagnosis: Parkinson’s symptoms are mainly manifested as tremor, muscle tonus, bradykinesia, postural gait abnormality, oral, pharyngeal, palatal muscle movement disorder. Parkinson’s neurological symptoms also include greasy face, constipation, abnormal sweating, excessive saliva, salivation, nearly half of the patients have depression or sleep disorders. 4, Medopa/Hypnin: with Medopa or Hypnin effective, can be initially judged as Parkinson’s disease, there are some Parkinson’s syndrome, early on Medopa is also effective, and even anisometropia, but the final diagnosis is not primary Parkinson’s disease. There are also primary Parkinson’s disease, with Medoxomil or Benzine, the effect is not obvious. 5, imaging tests MRI (magnetic resonance imaging) of the head: you can look at the basic condition of the brain, general neurology will be used as a basic examination program, which is conducive to the identification of Parkinson’s disease and certain Parkinson’s syndrome. TCS (Tonal Cerebral Cavity Ultrasound): specifically looks at the substantia nigra, which is the main problem in Parkinson’s disease. If there is a problem with the substantia nigra, Parkinson’s disease can be highly determined, and if you want to be further sure, you can consider a PET test.DAT-PET: It is currently the most accurate test in the auxiliary examination of Parkinson’s disease.
