1.2. Physiopathological Mechanisms of Alzheimer’s Disease.95% cases of AD are late-onset and sporadic, while around 5% of AD cases are early-onset and associated to genetic mutations in some proteins (e.g. presenilin 1, presenilin 2, amyloid precursor protein), which is known as familial AD.Interestingly, biochemical changes produced in familial AD seem similar to those in sporadic AD [].

It is difficult to document the actual prevalence of AD in underdeveloped and low-income countries due to the lack of accurate diagnosis and lack of record keeping in many cases, as most studies are based on a clinical diagnosis, either of dementia, irrespective of etiology, or …ific areas of the brain, such as the left cerebellar cortex and the right inferior occipital cortex, which are associated with language processing and facial recognition, respectively. The study also found that individuals with SCD-plus had higher levels of depression, higher LDL (high cholesterol), and less healthy lifestyles.
Even though the findings need more inquiry over time, this study offers a valuable snapshot of how memory complaints and certain risk factors can overlap with subtle brain changes. By knowing the warning signs, healthcare professionals and researchers can develop earlier and more targeted interventions. Early detection means patients could benefit from lifestyle changes, medications, or therapies aimed at maintaining brain health for as long as possible. This study highlights the importance of monitoring self-reported memory issues within the elderly population, as they might be the first sign of something more serious developing.

Unveiling Alzheimer’s: Insights from Omics-based Biomarkers and Early Detection
Table of Contents
Alzheimer’s disease (AD) remains a meaningful challenge in medical research and practice. Recent advancements in omics-based biomarkers and non-invasive molecular markers are offering promising avenues for early diagnosis and intervention. This interview delves into the latest research findings and their implications for dementia care.
Physiopathological Mechanisms of Alzheimer’s Disease
Senior Editor (SE): Dr. Emily thompson, could you explain the physiopathological mechanisms of Alzheimer’s disease and the differences between late-onset and early-onset forms?
Dr. emily Thompson (ET): Certainly. alzheimer’s disease is characterized by two main types: late-onset, which comprises 95% of cases and is sporadic, and early-onset, which accounts for about 5% and is associated with genetic mutations in proteins such as presenilin 1, presenilin 2, and amyloid precursor protein. These mutations lead to familial Alzheimer’s disease. Interestingly, the biochemical changes observed in familial AD are quiet similar to those in sporadic AD, suggesting a common underlying pathology.
Biomarkers in Dementia Research and Practice
SE: How have biomarkers progressed in the context of Alzheimer’s pathology, and what are the key recommendations for their clinical use?
ET: The research on biomarkers for Alzheimer’s pathology has advanced substantially. We now have a better understanding of how these biomarkers can be used to diagnose and monitor the disease. For clinical practice, it is indeed essential to use a combination of biomarkers, including cerebrospinal fluid markers (like tau and amyloid-beta), imaging biomarkers (such as PET scans), and genetic biomarkers. These biomarkers help in distinguishing alzheimer’s disease from other types of dementia and in predicting disease progression.
Developing Non-Invasive Molecular Markers
SE: What are the challenges in documenting the prevalence of Alzheimer’s disease in underdeveloped and low-income countries, and how can non-invasive molecular markers help in early risk assessment?
ET: Documenting the prevalence of Alzheimer’s disease in underdeveloped and low-income countries is challenging due to the lack of accurate diagnosis and record-keeping. Most studies rely on clinical diagnoses, which can be misleading.Non-invasive molecular markers, such as blood-based biomarkers, can help in early risk assessment. These markers can detect subtle changes in the brain, such as those associated with language processing and facial recognition, even before clinical symptoms appear. This early detection can lead to timely interventions, including lifestyle changes, medications, and therapies aimed at maintaining brain health.
Implications for Healthcare Professionals
SE: what are the implications of these findings for healthcare professionals, and how can they use this information to improve patient outcomes?
ET: These findings highlight the importance of monitoring self-reported memory issues within the elderly population, as they might be the first sign of something more serious developing. Healthcare professionals should be vigilant in identifying warning signs and developing earlier and more targeted interventions. By doing so, they can help patients benefit from lifestyle changes, medications, or therapies aimed at maintaining brain health for as long as possible.
Conclusion
SE: Dr. Thompson, what are the main takeaways from our discussion today?
ET: The main takeaways are the significance of omics-based biomarkers in early Alzheimer’s disease diagnosis and the potential of non-invasive molecular markers for early risk assessment. These tools can revolutionize the way we approach dementia care, enabling earlier interventions and better patient outcomes. It is crucial for healthcare professionals to stay informed about these advancements and utilize them in clinical practice to improve the lives of patients with Alzheimer’s disease.
