Alzheimer

Alzheimer's disease (AD) is a progressive neurodegenerative disorder associated with the accumulation of abnormal proteins, including amyloid-beta and tau, in the brain. Recent evidence suggests that the glymphatic and meningeal lymphatic systems, which contribute to the removal of waste products from the brain, may play a role in AD. In particular, impaired drainage through the deep cervical lymphatic system may contribute to the accumulation of disease-related proteins. The LymphDAD study is a prospective, single-center pilot study designed to explore whether surgically improving cervical lymphatic drainage may be associated with changes in biological markers, brain imaging, and cognitive and clinical measures in selected patients with AD who are not eligible for currently available disease-modifying treatments. Five participants with AD will undergo a minimally invasive microsurgical procedure called lymphovenous anastomosis (LVA), in which small cervical lymphatic vessels are connected to nearby small veins to facilitate lymphatic drainage. During the procedure, a small sample of lymphatic fluid will also be collected for exploratory analysis of amyloid-beta and tau proteins. Participants will undergo clinical and neuropsychological assessments, blood sampling, magnetic resonance imaging (MRI), and amyloid positron emission tomography (PET) before the procedure and during follow-up. Follow-up assessments will be performed at 1, 3, 6, and 12 months after surgery. The study is exploratory and is not designed to demonstrate a definitive clinical benefit. Its primary purpose is to obtain preliminary information on the feasibility, safety, and possible biological and clinical effects of cervical LVA in AD, which may support the design of future controlled studies.

The aim of the program to serve as a prototype for future preventive program for AD in the region. The program will recruit elderly participants. Cognitive assessment and lifestyle questionnaire will be performed with each participant to investigator their risk factor associate with AD. The program will offer medical referral and/or educational program(s) (e.g. tailor-made multidomain preventive measures plan, education talks) for participants who might have possible early AD or with high risk of AD

ALZEVIT is a nationwide, decentralized, digital-first cohort study in France designed to establish a large-scale Apolipoprotein E (APOE) genotyping registry and enable precision prevention strategies for Alzheimer's disease (AD). Sponsored by Firalis SA and conducted in collaboration with French memory centers, it addresses the need for early identification of individuals at high genetic risk, particularly APOE ε4 carriers and ε4/ε4 homozygotes, in the context of emerging disease-modifying therapies most effective in preclinical or early disease stages. Using an online recruitment platform, participants aged ≥45 years provide electronic informed consent and self-collected saliva samples via home collection kits for centralized APOE genotyping using the APO-Easy® assay, compliant with EU IVDR and US FDA requirements. Data are stored in a secure registry compliant with GDPR. Phase A (0-18 months) will enroll 50,000 participants to determine national APOE genotype distribution, identify high-risk individuals, and evaluate feasibility of large-scale digital genetic screening, with longitudinal online follow-up including cognitive and risk factor assessments. Phase B (12-24 months) includes detailed phenotyping of \~2,350 selected participants across all APOE genotypes, including \~750 ε4/ε4 homozygotes. Participants undergo clinical evaluation, MRI, cognitive testing, and multi-omics biomarker profiling (genomics, proteomics, metabolomics, environmental exposure), conducted at memory centers or via telemedicine. The study classifies participants along the cognitive continuum, including cognitively normal individuals, preclinical AD, mild cognitive impairment (MCI), and mild or moderate AD, to identify genotype-specific trajectories and modifiable risk and resilience factors. ALZEVIT aims to establish a scalable national infrastructure linking genetic stratification with longitudinal biomarker and clinical data to support prevention trials, improve understanding of APOE-related heterogeneity, and advance precision medicine for Alzheimer's disease.

Telemedicine has developed rapidly during the COVID-19 pandemic and is now integrated into the clinical practice of many hospitals. Telemedicine offers many advantages, and even after the end of the pandemic, many patients still choose to undergo healthcare visits remotely. However, the rapid expansion of telemedicine may be associated with the risk of providing patients with unvalidated and uncontrolled telehealth solutions, potentially negatively impacting their health. In this study, the researchers aim to investigate the effectiveness of remote cognitive training in patients with mild-to-moderate Alzheimer's disease (AD) using tablets equipped with virtual reality-based cognitive exercises. The investigators also aim to evaluate the impact of online supervision of cognitive training by a neuropsychologist and to compare the costs and burden of home-based versus hospital-based cognitive training in patients with AD. This project will define the optimal modalities for cognitive telerehabilitation to ensure validated protocols for the continuity of care in AD.

To evaluate the safety and tolerability of low-dose whole brain radiotherapy (WBRT) delivered as an induction course of 0.3 Gy × 10 fractions (3.0 Gy total) followed by 12 months of monthly maintenance LDRT (0.3 Gy × 10 fractions; 3.0 Gy total) in patients with Alzheimer's disease or dementia with inflammatory components

Malnutrition among hospitalized patients is a critical, yet often overlooked, public health issue associated with increased complications, longer hospital stays, higher mortality, and greater healthcare costs. In Iraq, factors such as dietary patterns, the burden of chronic diseases, and healthcare constraints may increase the risk of hospital-acquired malnutrition. Current standard care may not include systematic nutritional screening or protocol-driven support. This trial aims to test whether implementing an individualized nutritional support program can improve clinical outcomes for at-risk medical inpatients in Iraqi hospitals, building upon evidence from international studies
