Therapeutic Use Of Music For Geriatric Dementia Patients, Katelynn Roscioli

Scholar Week 2016 - present

Dementia impacts millions of individuals and their families worldwide, yet many caregivers remain untrained, unpaid, and unable to maintain their own health while caring for their patients. Despite the need for support, limited resources exist to aid these caregivers in combatting this progressive, debilitating disease. One possibility lies in practices rooted in music therapy, which have been shown to restore memory retention, personhood, and quality of life in dementia patients. However, individuals outside of music therapists, especially those with limited musical backgrounds, may not consider implementing music therapy within their care plan. To make this approach more accessible, a website …

Digital Clock Drawing As An Alzheimer's Disease Susceptibility Biomarker: Associations With Genetic Risk Score And Apoe In Older Adults, L I Thompson, M Cummings, S Emrani, David J. Libon, A Ang, C Karjadi, R Au, C Liu

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

BACKGROUND: Alzheimer's disease (AD) is the leading cause of dementia in older adults, but most people are not diagnosed until significant neuronal loss has likely occurred along with a decline in cognition. Non-invasive and cost-effective digital biomarkers for AD have the potential to improve early detection.

OBJECTIVE: We examined the validity of DCTclockTM (a digitized clock drawing task) as an AD susceptibility biomarker.

DESIGN: We used two primary independent variables, Apolipoprotein E (APOE) ε4 allele carrier status and polygenic risk score (PRS). We examined APOE and PRS associations with DCTclockTM composite scores as dependent measures.

SETTING: We used existing data …

Hippocampal Volume And The Detection Of Mild Cognitive Impairment In An Older Adult Population: Assessing Performance On Cognitive Screeners Administered In-Person And Electronically, Kristen Fabrizi

Dissertations

The present study investigated how performance on in-person and electronic neuropsychological assessment measures predicted subcortical hippocampal volume and cognitive decline consistent with mild cognitive impairment. It was hypothesized that the Montreal Cognitive Assessment would display better predictive strength than the Cogstate Brief Battery when evaluating subcortical hippocampal volume measured via structural magnetic resonance imaging. It was further hypothesized that the Montreal Cognitive Assessment would be more sensitive to predicting group membership to the diagnostic classification of mild cognitive impairment compared to the Cogstate Brief Battery. The sample included 445 older adult participants selected from the Alzheimer’s Disease Neuroimaging Initiative 3. …

Refugees Living With Dementia: Assessing The Barriers To Healthcare Access In Crisis-Affected Populations In Lebanon And Switzerland, And The Role Humanitarian Actors Have On Addressing Them, Pedro Gomez

Independent Study Project (ISP) Collection

As life expectancies increase in many places around the world, the prevalence of aging populations has increased. Consequently, increased numbers of people globally, especially in developing countries, have been diagnosed with conditions associated with old age. Dementia, a group of conditions associated with impaired cognitive functions, is among these. Notwithstanding, many developing countries have done poorly with regards to diagnosing and treating dementia, with some cultures not even having a word to describe the condition. (ADI 2022). The lack of a diagnosis and knowledge about dementia for some refugee communities has led to healthcare challenges in their host countries (Corfield …

Estimating Dementia Risk In An African American Population Using The Dctclock, Marissa Ciesla, Jeff Pobst, Joyce Gomes-Osman, Melissa Lamar, Lisa L Barnes, Russell Banks, Ali Jannati, David Libon, Rodney Swenson, Sean Tobyne, David Bates, John Showalter, Alvaro Pascual-Leone

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

The prevalence of Alzheimer's disease (AD) and related dementias (ADRD) is increasing. African Americans are twice as likely to develop dementia than other ethnic populations. Traditional cognitive screening solutions lack the sensitivity to independently identify individuals at risk for cognitive decline. The DCTclock is a 3-min AI-enabled adaptation of the well-established clock drawing test. The DCTclock can estimate dementia risk for both general cognitive impairment and the presence of AD pathology. Here we performed a retrospective analysis to assess the performance of the DCTclock to estimate future conversion to ADRD in African American participants from the Rush Alzheimer's Disease Research …

Can Variables From The Electronic Health Record Identify Delirium At Bedside?, Ariba Khan, Kayla Heslin, Michelle Simpson, Michael L. Malone

Journal of Patient-Centered Research and Reviews

Delirium, a common and serious disorder in older hospitalized patients, remains underrecognized. While several delirium predictive models have been developed, only a handful have focused on electronic health record (EHR) data. This prospective cohort study of older inpatients (≥ 65 years old) aimed to determine if variables within our health system’s EHR could be used to identify delirium among hospitalized patients at the bedside. Trained researchers screened daily for delirium using the 3-minute diagnostic Confusion Assessment Method (3D-CAM). Patient demographic and clinical variables were extracted from the EHR. Among 408 participants, mean age was 75 years, 60.8% were female, and …

COGNISTAT as a neuropsychological instrument is a recent screener being introduced to a few outpatient clinics. In this study; COGNISTAT is translated to Filipino for the first time using a rigorous procedure and pilot tested on elderly volunteers in local …

Plasmalogen Deficiency: A Risk Factor For Dementias And Potential Treatment Target, Mitchel A. Kling, Mallika Mendu, Rima F. Kaddurah-Daouk, Sheldon Jordan, Dayan B. Goodenowe

Rowan-Virtua Research Day

Altered lipid metabolism is implicated in the risk of sporadic Alzheimer’s disease (AD) and related dementias (ADRD); however, the precise mechanisms accounting for findings from observational studies remains to be fully elucidated.

Plasmalogens are a subclass of integral membrane phospholipids with unique properties that appear to play important roles relevant to the pathophysiology of AD and ADRD, including vesicle fusion necessary for synaptic neurotransmitter release, modulation of membrane fluidity and microdomain dynamics, membrane antioxidant functions, and neuroprotection. Like the more familiar phosphatides, plasmalogens are synthesized on a 3-carbon glycerol backbone; however, they differ from phosphatides by the presence of a …

Alzheimer's And Patient Caregiver Burnout: A Review Of The Literature, Madeline Hekeler

James Madison Undergraduate Research Journal (JMURJ)

The term “silent epidemic” is fitting for Alzheimer’s disease (AD), as its negative impact is widely felt but rarely discussed. Burnout among AD caregivers has become an epidemic of its own as caregivers experience an increase in health risks, stress, and financial burden. This literature review focuses on caregiver burnout and how imperative it is that caregivers are better supported in their role. Researchers have developed instruments to assess and intervene in caregiver burnout that have shown effectiveness among caregivers and their families.Nevertheless, further longitudinal research is warranted regarding more effective interventions, including stress management and social support mechanisms.

Recent Advances In Our Molecular And Mechanistic Understanding Of Misfolded Cellular Proteins In Alzheimer’S Disease (Ad) And Prion Disease (Prd), Walter J. Lukiw

School of Medicine Faculty Publications

Naturally occurring neuron-abundant proteins including amyloid Aβ42 peptide and the microtubule-associated protein tau (MAPT) can, over time and under pathological situations, assume atypical conformations, altering their normal biological structure and function, and causing them to aggregate into insoluble and neurotoxic intracellular inclusions. These misfolded proteins ultimately contribute to the pathogenesis of several progressive, age-related and ultimately lethal human neurodegenerative disorders. The molecular mechanism of this pathological phenomenon of neuronal protein misfolding lends support to the ‘prion hypothesis’, which predicts that the aberrant folding of endogenous natural protein structures into unusual pathogenic isoforms can induce the atypical folding of other similar …

Identifying the leading health and lifestyle factors for the risk of incident dementia and Alzheimer's disease has yet to translate to risk reduction. To understand why, we examined the discrepancies between observational and clinical trial evidence for seven modifiable risk factors: type 2 diabetes, dyslipidemia, hypertension, estrogens, inflammation, omega-3 fatty acids, and hyperhomocysteinemia. Sample heterogeneity and paucity of intervention details (dose, timing, formulation) were common themes. Epidemiological evidence is more mature for some interventions (eg, non-steroidal anti-inflammatory drugs [NSAIDs]) than others. Trial data are promising for anti-hypertensives and B vitamin supplementation. Taken together, these risk factors highlight a future need …

Intra-Arterial Combination Therapy For Experimental Acute Ischemic Stroke, Michael E. Maniskas, Jill M. Roberts, Amanda A. Gorman, Gregory J. Bix, Justin F. Fraser

Neurosurgery Faculty Publications

Acute ischemic stroke continues to devastate millions of individuals worldwide. Current treatments work to restore blood flow but not rescue affected tissue. Our goal was to develop a combination of neuroprotective agents administered intra-arterially following recanalization to target ischemic tissue. Using C57Bl/6J male mice, we performed tandem transient ipsilateral middle cerebral/common carotid artery occlusion, followed by immediate intra-arterial pharmacotherapy administration through a standardized protocol. Two pharmacotherapy agents, verapamil and lubeluzole, were selected based on their potential to modulate different aspects of the ischemic cascade; verapamil, a calcium channel blocker, works in an acute fashion blocking L-type calcium channels, whereas lubeluzole, …

Primary care integration of Down syndrome (DS)-specific dementia screening is strongly advised. The current study employed principal components analysis (PCA) and classification and regression tree (CART) analyses to identify an abbreviated battery for dementia classification. Scale- and subscale-level scores from 141 participants (no dementia n = 68; probable Alzheimer’s disease n = 73), for the Severe Impairment Battery (SIB), Dementia Scale for People with Learning Disabilities (DLD), and Vineland Adaptive Behavior Scales—Second Edition (Vineland-II) were analyzed. Two principle components (PC1, PC2) were identified with the odds of a probable dementia diagnosis increasing 2.54 times per PC1 unit increase and by …

Rule Out Screening For Undiagnosed Dementia And Alzheimer’S Disease Using An Ehr Based Machine Learning Solution, Branum Stephan, David A. Julovich, Dustin Bracy, Jeff Nguyen

SMU Data Science Review

Abstract. Current detection methods for Dementia and Alzheimer’s disease include cerebral spinal fluid (CSF) markers and/or the use of positron emission tomography (PET) imaging, both being high-cost, highly invasive testing methods. The need for low-cost, minimally invasive methods to prescreen individuals for cognitive impairment has been a challenge for many years. Today’s costs associated with an annual screen for all adults 65 and above using current methods (CSF, PET) reach well beyond trillions of dollars per year. Motivated by the limited accessibly and high costs, an alternative tool presented within this paper demonstrates an effective rule out screening for Dementia …
