파킨슨병증과 파킨슨병

There are no biological markers for the antemortem diagnosis of degenerative parkinsonian disorders, diagnosis currently relies upon the presence and progression of clinical features and confirmation depends on neuropathology. Clinicopathologic studies have shown significant false-positive and false-negative rates for diagnosing these disorders, and misdiagnosis is especially common during the early stages of these diseases. The diagnosis of the atypical parkinsonian disorders is relevant in clinical practice since prognosis and treatment of patients with these disorders differs from those with Parkinson's disease.
