Three different methods confirmed the association of macro and microelements with cerebrospinal fluid biomarkers of Alzheimer's disease
The homeostasis of metals is altered in the brain of Alzheimer’s disease (AD) patients. It was proposed that changes in metal homeostasis are related to AD pathology. Additionally, metals that are not present in the brain under normal circumstances (such as mercury, lead and cadmium) were associated with AD pathogenesis. The aim of this study was to test if macro and microelements (Li, B, Na, Mg, Al, S, K, Ca, Cr, Fe, Co, Mn, Ni, Cu, Zn, As, Se, Sr, Mo, Cd, Ba, Tl, Pb, and Hg) measured in cerebrospinal fluid (CSF) and plasma of patients with dementia are associated with CSF biomarkers of AD. CSF AD biomarkers reflect pathological changes in AD brain, while the involvement of different metals in AD pathogenesis is still the matter of debate. Macro and microelements were determined by inductively coupled plasma mass spectroscopy (ICP-MS), while CSF biomarkers were measured by enzyme-linked immunosorbent assays (ELISA). Macro and microelements were measured in CSF of 194 subjects and in plasma of 144 subjects (study included overall 125 AD patients, 50 patients with mild cognitive disorder and 19 healthy controls). We used three different statistical methods to test the association of macro and microelements with CSF biomarkers of AD. All three methods (simple correlation and two machine learning algorithms ; redescription mining and principal component analysis [PCA]) demonstrated the association of macro and microelements with CSF biomarkers of AD. Possible explanations for association of macro and microelements with CSF biomarkers of AD await elucidation of their environmental sources or detection of their release from brain tissue due to cell death. Also, these results should be further validated on larger cohorts.
