High homocysteine levels as potential indicators of subacute combined degeneration of the spinal cord.

Homocysteine (Hcy) is widely recognized as a significant risk factor for cardiovascular and cerebrovascular diseases. However, our research has uncovered a novel perspective, suggesting that elevated levels of Hcy could serve as an indicator for neurological diseases. This article presents a unique case of Subacute Combined Degeneration of the spinal cord(SCD), characterized by high homocysteine levels, yet normal vitamin B12 and imaging results. This discovery could facilitate early detection and ensure timely referral of patients to specialized departments for further treatment.
