Background Previous studies have reported that elevated total homocysteine levels are associated with cognitive dysfunction. However, few studies have examined the radiological markers of associated neuropathology in A lzheimer's disease ( AD ). We hypothesized that elevated levels of homocysteine are associated with cerebral grey matter volume loss. We compared the grey matter in a high homocysteine group and a normal homocysteine group using an optimized voxel‐based morphometry. Methods The study included 79 patients with AD who were divided into two groups: a high homocysteine group and a normal homocysteine group. The participants underwent brain magnetic resonance imaging using a standardized protocol and neurocognitive evaluation. Homocysteine tests and other routine laboratory examinations for dementia assessment were carried out in all patients. Results There was no significant difference in grey matter volume between the patients with high homocysteine levels and those with normal homocysteine levels. A multiple regression analysis also revealed that the levels of homocysteine were not associated with the grey matter volume in patients with AD . Homocysteine levels were not correlated significantly with M ini‐ M ental S tate E xamination, G lobal D eterioration S cale, or C linical D ementia R ating. Conclusion Our results showed that elevated homocysteine levels are not associated with reduced cerebral grey matter volume in AD . Larger samples will be needed to assess potential correlations between homocysteine and neuroanatomical pathology in the future.
