Clinical and biochemical alterations in tremor: evidence from serum elements, blood counts, and liver function: a cross-sectional study

Aim: Tremor is one of the most common neurological movement disorders, arising from dysfunction in the neuromuscular system. However, comprehensive analyses of peripheral blood elements, red blood cells (RBC) and white blood cells (WBC) counts, as well as liver and kidney function in patients with tremor remain limited. This cross-sectional study investigated alterations in serum elements, complete blood counts, and liver function in patients with tremor. The study sought to identify independent risk factors and evaluate their diagnostic performance. Methods: Blood samples from 79 patients with tremor and 82 healthy controls were analyzed. Serum elements, RBC, WBC, platelet (PLT), liver function, and renal function were measured using the QL8000 element analyzer, XN 2800 automated hematology analyzer, and Roche Cobas 8000 system. Results: Serum copper (Cu) and lead (Pb) levels were significantly elevated in tremor patients. These patients also showed increased monocytes, decreased eosinophils, and impaired liver function, including elevated aspartate aminotransferase and globulin with reduced albumin. Conclusions: Tremor patients show distinct alterations in Cu, Pb, monocyte counts, eosinophil counts, and liver function markers. These findings suggest that these parameters may serve as potential diagnostic indicators and therapeutic targets. Cu and Pb were identified as independent risk factors, and their combination significantly improved diagnostic efficiency.
