The use of digital technologies may help to diagnose Alzheimer's Disease (AD) at the pre-symptomatic stage. However, before implementation into clinical practice, digital measures (DMs) need to be evaluated for their diagnostic benefit compared to established questionnaire-based assessments, such as Mini-Mental State Examination (MMSE) and Functional Activity Questionnaire (FAQ). We analyzed data from smartphone based virtual reality game and Alzheimer's Disease Neuroimaging Initiative (ADNI). We employed an Artificial Intelligence (AI) based approach to elucidate the relationship of DMs to MMSE and FAQ. Furthermore, we used Machine Learning (ML) and statistical methods to assess the diagnostic benefit of DMs compared to questionnaire-based scores. We found non-trivial relationships between DMs, MMSE, and FAQ which can be visualized as a complex network. DM showed a better ability to discriminate between different stages of the disease than questionnaire-based methods. Our results indicate that DMs have the potential to act as a crucial measure in the early diagnosis and staging of AD.

Abstract Objective Individuals with probable Alzheimer’s disease (pAD) often have neuropsychiatric symptoms; however, the relationship of these symptoms and ApoE4 status is unclear. Recent research suggests gender moderates the relationship of ApoE4 to AD. We examined how ApoE4 genetic status and gender predict neuropsychiatric symptoms in older adults with pAD. Method Data from the National Alzheimer’s Coordinating Centers (NACC) was utilized in the present study. We included only individuals diagnosed with pAD with collaterals who were judged reliable by clinical NACC staff and who saw the participant at least three times per week. The selected sample (N = 6943) was 52% male; 85.6% White, 10.2% African American; and 7.5% Hispanic. Average age was 73 years. The Neuropsychiatric Inventory-Questionnaire, completed by the participant’s collateral, was used to assess symptoms. Analyses controlled for age and cognitive impairment as measured by the Mini-Mental State Examination. Results The presence of at least one ApoE4 allele predicted higher severity of delusions, p = .04. Males had higher severity of agitation, apathy, and irritability; females had higher delusions, depression, and anxiety, all p’s < .05. Gender moderated the relationship of ApoE4 with disinhibition, night disturbances, and appetite, all p’s < .05. In all three cases, for males, scores were higher for non-carriers than for ApoE4 carriers; however, for females, differences did not exist between carriers and non-carriers. Conclusions Differences between ApoE4 carriers and non-carriers as well as between genders are demonstrated, and evidence supports the hypothesis that gender and ApoE4 status interact to predict some pAD neuropsychiatric symptomatology.

Background: Alzheimer’s disease (AD), the most threatening neurodegenerative disease, is characterized by the loss of memory and language function, an unbalanced perception of space, and other cognitive and physical manifestations. The pathology of AD is characterized by neuronal loss and the extensive distribution of senile plaques and neurofibrillary tangles (NFTs). The role of environment and the diet in AD is being actively studied, and nutrition is one of the main factors playing a prominent role in the prevention of neurodegenerative diseases. In this context, the relationship between dementia and wine use/abuse has received increased research interest, with varying and often conflicting results. Scope and Approach: With this review, we aimed to critically summarize the main relevant studies to clarify the relationship between wine drinking and AD, as well as how frequency and/or amount of drinking may influence the effects. Key Findings and Conclusions: Overall, based on the interpretation of various studies, no definitive results highlight if light to moderate alcohol drinking is detrimental to cognition and dementia, or if alcohol intake could reduce risk of developing AD.

Abstract In addition to cognitive impairment, apathy is increasingly recognized as an important neuropsychiatric syndrome in Alzheimer's disease (AD). Aims: To identify the relationship between dementia severity and apathy levels, and to discuss the association of this condition with other psychopathological manifestations in AD patients. Methods: This study involved 15 AD patients (mean age: 77 years; schooling: 4.9 years), with mild, moderate and severe dementia, living in Rio Claro SP, Brazil. Procedures included evaluation of cognitive status by the Mini-Mental State Examination, Clinical Dementia Rating, and Global Deterioration Scale. Apathy syndrome was assessed by the Apathy Evaluation Scale and Neuropsychiatric Inventory (NPI-apathy domain). Other psychopathological manifestations such as depression were also considered. Results: Patients with more severe dementia presented higher levels of apathy, reinforcing the hypothesis that apathy severity aggravates as the disease progresses. Using the Spearman coefficient correlation an association was identified between the MMSE and Apathy Evaluation Scale (r=0.63; p=0.01), and also between the MMSE and NPI-apathy domain (r=0.81; p=0.01). Associations were also found between the Global Deterioration Scale and Apathy Evaluation Scale (r=0.58; p=0.02), and between the Global Deterioration Scale and NPI-apathy domain (r=0.81; p=0.01). Conclusions: Apathy is a distinct syndrome among patients with AD and increases with global deterioration.
