Medications these patients received were reviewed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Metal abnormalities were detected in over half the subjects, including evidence of mercury, lead, and arsenic elevation as well as instances of excessive essential metals, iron (Fe), and copper. Some metal aberration was detected in 64% of the DE group and 66% of the MCI group. Females were more likely to have elevated copper, consistent with hormonal effects on copper excretion. Homocysteinemia was the most common abnormality, detected in 71% with DE and 67% with MCI, while methylmalonic acid was not elevated. Slight hyperammonemia was moderately common (38%) suggesting a hepatic factor in this subset. Findings of moderate insulin resistance were present in nearly half (44% DE, 52% MCI). Sixty of 65 (92%) had at least one abnormal biomarker and 60% had two or more. The most common drug taken by the total cohort was proton pump inhibitors at 22% DE and 38% MCI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>This study suggests that both toxic metals and excessive vital metals such as copper and iron, as well as common metabolic and hepatic factors are detectable at both stages of MCI and DE. There appears to be a multiplicity of provocative factors leading to DE. Individualized interventions based on these parameters may be a means to reduce cognitive decline leading to DE. A more comprehensive prospective study of these environmental and metabolic factors with corrective early interventions appears warranted.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1089\/jicm.2023.0583","type":"journal-article","created":{"date-parts":[[2024,2,8]],"date-time":"2024-02-08T17:16:46Z","timestamp":1707412606000},"page":"793-801","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Metabolic and Environmental Biomarkers in Mild Cognitive Impairment and Dementia: An Exploratory Study"],"prefix":"10.1177","volume":"30","author":[{"given":"Abigail C.","family":"Lyon","sequence":"first","affiliation":[{"name":"Department of Neurology, Cognitive Disorders &amp; Comprehensive Alzheimer's Disease Center, Vickie &amp; Jack Farber Institute for Neuroscience, Thomas Jefferson University Hospital, Philadelphia, PA, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carol F.","family":"Lippa","sequence":"additional","affiliation":[{"name":"Department of Neurology, Cognitive Disorders &amp; Comprehensive Alzheimer's Disease Center, Vickie &amp; Jack Farber Institute for Neuroscience, Thomas Jefferson University Hospital, Philadelphia, PA, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3906-5509","authenticated-orcid":false,"given":"Arnold R.","family":"Eiser","sequence":"additional","affiliation":[{"name":"Senior Scholar, Penn Center for Public Health, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,8,21]]},"reference":[{"key":"e_1_3_5_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/alz.12283"},{"key":"e_1_3_5_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-021-23620-z"},{"key":"e_1_3_5_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/ana.10440"},{"key":"e_1_3_5_5_2","doi-asserted-by":"publisher","DOI":"10.3329\/jhpn.v22i4.284"},{"key":"e_1_3_5_6_2","doi-asserted-by":"publisher","DOI":"10.3233\/JAD-210166"},{"key":"e_1_3_5_7_2","doi-asserted-by":"publisher","DOI":"10.2147\/NDT.S383654"},{"key":"e_1_3_5_8_2","doi-asserted-by":"publisher","DOI":"10.3389\/fnmol.2016.00057"},{"key":"e_1_3_5_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/s0197-0186(02)00041-4"},{"key":"e_1_3_5_10_2","doi-asserted-by":"publisher","DOI":"10.3390\/nu10050564"},{"key":"e_1_3_5_11_2","doi-asserted-by":"publisher","DOI":"10.1001\/jamanetworkopen.2019.7978"},{"key":"e_1_3_5_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/jat.4037"},{"key":"e_1_3_5_13_2","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.REV120.008207"},{"key":"e_1_3_5_14_2","doi-asserted-by":"publisher","DOI":"10.1002\/alz.12282"},{"key":"e_1_3_5_15_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.56.3.303"},{"key":"e_1_3_5_16_2","first-page":"10","article-title":"Diagnostic and Statistical Manual of Mental Disorders (5th ed.)","author":"American Psychiatric Association","year":"2013","unstructured":"American Psychiatric Association.
