Can Parkinsonism be a solitary manifestation of Wilson's Disease?

Abstract

Wilson's disease (WD) is a secondary parkinsonian condition that results in multi-organ dysfunction. Accurately diagnosing this disorder as soon as possible is crucial since it is a treatable condition. In order to diagnose WD, a doctor must be aware of the disorder's early signs and request the following diagnostic tests. These include serum ceruloplasmin levels, 24-hour urinary copper excretion, slit-lamp examination for Kayser-Fleischer rings, liver biopsy, and ATP7B genetic testing when needed. It is mentioned that WD can present with a wide range of manifestations; however, according to our observations of thoroughly analyzing cases and papers concerning WD patients, we conclude that parkinsonism cannot be the only early symptom of WD. Most patients who developed parkinsonian symptoms also showed accompanying features such as dysarthria, dystonia, or behavioral changes. This finding would assist doctors in rolling out WD diagnosis and focusing on other potential diseases. By avoiding unnecessary investigations for WD in cases of isolated, typical parkinsonism, physicians can more effectively allocate resources and explore other more probable differential diagnoses. This situation allows for earlier initiation of appropriate therapy tailored to the correct underlying condition, and the overall financial burden on individuals and health systems would be lessened. Such an approach would also help reduce patient anxiety caused by uncertainty.
