Apoe Gene Associated With Cholesterol-Related Traits In The Hispanic Population, Stephanie Lozano, Victoria I. Padilla, Manuel Lee Avila, Mario Gil, Gladys E. Maestre, Kesheng Wang, Chun Xu

Health & Biomedical Sciences Faculty Publications and Presentations

Genetic variants in the apolipoprotein E (APOE) gene are associated with lipid metabolism and lipid-related traits in the non-Hispanic population. There have been limited studies regarding the association between the APOE gene and hypercholesterolemia in the Hispanic population; therefore, our aim for this study is to examine the APOE gene’s associations with cholesterol level and its related phenotypes. The APOE gene consists of three different alleles, ε2, ε3, and ε4, with ε4 being associated with dementia and cardiovascular diseases. A total of 1,382 subjects were collected from the Texas Alzheimer’s Research and Care Consortium (TARCC, N = 1320) and the …

Virtual Reality (Vr)-Based Environmental Enrichment In Older Adults With Mild Cognitive Impairment (Mci) And Mild Dementia, Waleed Riaz, Zain Yar Khan, Ali Jawaid, Suleman Shahid

Medical College Documents

Background: Despite an alarming rise in the global prevalence of dementia, the available modalities for improving cognition and mental wellbeing of dementia patients remain limited. Environmental enrichment is an experimental paradigm that has shown promising anti-depressive and memory-enhancing effects in pre-clinical studies. However, its clinical utility has remained limited due to the lack of effective implementation strategies.
Objective: The primary objective of this study was to evaluate the usability (tolerability and interactivity) of a long-term virtual reality (VR)- based environmental enrichment training program in older adults with mild cognitive impairment (MCI) and mild dementia. A secondary objective was to assess …

Background:

Neuropsychiatric symptoms play an important role in diagnosing and clinical follow-up of cognitive impairment and dementia.

Objective:

We investigated the relationship between neuropsychiatric symptoms, cognitive impairment, and dementia in Hispanics.

Methods:

We included 529 participants (age ≥40 years) from the Maracaibo Aging Study with standardized neuropsychiatric assessments, including the Neuropsychiatric Inventory (NPI). Based on the Clinical Dementia Rating and the Mini-Mental State Examination scores, participants’ cognitive status was categorized into normal cognition, mild/moderate, and severe cognitive impairment. Diagnosis of dementia was established in a consensus conference. Statistical analyses included multivariable logistic regression models and area under the curve (AUC). …

Association Of Dementia With Immunoglobulin G N-Glycans In A Chinese Han Population, Xiaoyu Zhang, Hui Yuan, Jihui Lyu, Xiaoni Meng, Qiuyue Tian, Yuejin Li, Jie Zhang, Xizhu Xu, Jing Su, Haifeng Hou, Dong Li, Baoliang Sun, Wei Wang, Youxin Wang

Immunoglobulin G (IgG) functionality can drastically change from anti- to proinflammatory by alterations in the IgG N-glycan patterns. Our previous studies have demonstrated that IgG N-glycans associated with the risk factors of dementia, such as aging, dyslipidemia, type 2 diabetes mellitus, hypertension, and ischemic stroke. Therefore, the aim is to investigate whether the effects of IgG N-glycan profiles on dementia exists in a Chinese Han population. A case–control study, including 81 patients with dementia, 81 age- and gender-matched controls with normal cognitive functioning (NC) and 108 non-matched controls with mild cognitive impairment (MCI) was performed. Plasma IgG N-glycans were separated …

A White Matter Connection Of Schizophrenia And Alzheimer’S Disease, Peter Kochunov, Artemis Zavaliangos-Petropulu, Neda Jahanshad, Paul M. Thompson, Meghann C. Ryan, Joshua Chiappelli, Shuo Chen, Xiaoming Du, Kathryn Hatch, Bhim Adhikari, Joanne E. Curran, John Blangero

Schizophrenia (SZ) is a severe psychiatric illness associated with an elevated risk for developing Alzheimer’s disease (AD). Both SZ and AD have white matter abnormalities and cognitive deficits as core disease features. We hypothesized that aging in SZ patients may be associated with the development of cerebral white matter deficit patterns similar to those observed in AD. We identified and replicated aging-related increases in the similarity between white matter deficit patterns in patients with SZ and AD. The white matter “regional vulnerability index” (RVI) for AD was significantly higher in SZ patients compared with healthy controls in both the independent …
