Understanding Alzheimer's Disease: Biomarkers and Early Detection

Beyond Dryness: Recognizing and Managing Sjögren's Syndrome in Everyday Care

In this episode of MD Newsline, Dr. Hina Tareen, a double board-certified rheumatologist and internal medicine physician, provides a comprehensive and practical guide to diagnosing and managing Sjögren's syndrome in everyday clinical practice. Drawing from her experience in private practice, she highlights the challenges of recognizing this often-overlooked autoimmune condition and emphasizes the importance of early suspicion and multidisciplinary care. Dr. Tareen walks through the hallmark symptoms of Sjögren's, including dry eyes and dry mouth, while underscoring the broader systemic nature of the disease. She discusses how to differentiate clinically significant disease from common dryness complaints, outlines a step-by-step diagnostic framework, and explores management strategies ranging from symptomatic relief to systemic immunosuppressive therapy. The conversation also addresses common pitfalls in diagnosis, the role of collaboration across specialties, and the importance of patient education and long-term monitoring. With emerging research on novel biomarkers and evolving treatment options, this episode offers valuable insights for clinicians navigating the complexities of Sjögren's syndrome. Episode Highlights: Recognizing Early Signs of Sjögren's Syndrome Dr. Tareen explains that persistent dry eyes and dry mouth are the most common presenting symptoms, but clinicians must also look beyond dryness to identify fatigue, joint pain, and systemic features. Distinguishing Sjögren's from Benign Dryness Clinical context is key—frequent use of artificial tears, difficulty swallowing dry foods, and associated systemic symptoms help differentiate Sjögren's from more common causes of dryness. Primary vs Secondary Sjögren's Syndrome Sjögren's often coexists with other autoimmune diseases like rheumatoid arthritis and lupus. Identifying whether the disease is primary or secondary is essential for guiding management. Diagnostic Approach and Laboratory Evaluation A thorough history and physical exam remain foundational. Key labs include ANA, ENA panel, inflammatory markers, complement levels, and organ function tests, with biopsy reserved for unclear cases. Managing Seronegative or Atypical Cases Patients who do not meet full criteria may still be treated based on clinical suspicion. Additional testing, including salivary gland biopsy, may help confirm the diagnosis when necessary. Assessing and Monitoring Systemic Involvement Clinicians must remain vigilant for extra-glandular manifestations, including renal, pulmonary, neurologic, and hematologic involvement, which may require imaging, lab monitoring, and specialist referrals. Stepwise Treatment Strategy Management begins with symptomatic relief for dryness, followed by systemic therapy such as hydroxychloroquine, methotrexate, or mycophenolate based on organ involvement and disease severity. Addressing Fatigue and Quality of Life Fatigue is often multifactorial. Dr. Tareen emphasizes evaluating sleep, mood, nutritional deficiencies, and overall disease control to improve patient outcomes. Long Diagnostic Journeys and Missed Opportunities Many patients experience years of symptoms before diagnosis due to vague presentations. Increasing awareness among clinicians can help reduce delays and improve care. Lymphoma Risk and Long-Term Monitoring While Sjögren's carries an increased lymphoma risk, careful monitoring through labs and clinical evaluation helps identify higher-risk patients and guide timely referrals. Patient Education and Self-Management Hydration, eye and dental care, and lifestyle modifications play a crucial role. Empowering patients with knowledge helps them better manage their condition and advocate for their care. Future Directions in Sjögren's Research Emerging biomarkers and new therapeutic options are on the horizon, offering hope for earlier diagnosis and more targeted treatment strategies. Key Takeaway: Dr. Tareen emphasizes that Sjögren's syndrome is a complex, systemic autoimmune disease that often presents subtly. Early recognition, a thorough clinical approach, and multidisciplinary collaboration are essential to improving patient outcomes and preventing long-term complications.

Beyond Back Pain: Recognizing and Treating Axial Spondyloarthritis Early

In this episode of MD Newsline, Dr. Jill Weintraub, founder of Integrative Rheumatology Consultants, explores the complexities of axial spondyloarthritis, a chronic inflammatory condition that often goes undiagnosed for years. Dr. Weintraub provides a comprehensive overview of this umbrella disease, including its radiographic and non-radiographic forms, and explains why early recognition is critical to preventing long-term damage. She highlights the key differences between inflammatory and mechanical back pain, the challenges in diagnosing women, and the role of advanced imaging such as MRI. The conversation also dives into the interplay between genetics, the gut microbiome, and immune system dysfunction, as well as how modern therapies—from TNF inhibitors to JAK inhibitors—are transforming patient outcomes. Dr. Weintraub emphasizes the importance of integrating lifestyle interventions like exercise and physical therapy alongside medical treatment to improve long-term quality of life. Episode Highlights: Understanding Axial Spondyloarthritis Dr. Jill Weintraub explains axial spondyloarthritis as an umbrella of inflammatory diseases primarily affecting the spine, while also involving joints and entheses. She distinguishes between radiographic (ankylosing spondylitis) and non-radiographic forms, emphasizing how evolving definitions are improving diagnosis. Recognizing Inflammatory Back Pain A key diagnostic feature is inflammatory back pain, typically presenting before age 40 with morning stiffness that improves with movement. Dr. Weintraub contrasts this with mechanical back pain and highlights why this distinction is critical in clinical practice. Diagnostic Challenges and Delays Diagnosis can take years, especially in women, due to atypical presentations and central sensitization of pain. She stresses the importance of patient advocacy and clinician awareness to reduce delays. Role of Imaging and Clinical Evaluation MRI of the pelvis with appropriate sequences is essential for early detection, particularly in non-radiographic disease. However, Dr. Weintraub underscores that diagnosis remains largely clinical, as lab markers may often appear normal. Genetics, Microbiome, and Immune Interplay The episode explores how genetic factors like HLA-B27, combined with environmental triggers and gut microbiome imbalances, contribute to disease development and progression. Treatment Strategies and Biologic Selection Dr. Weintraub discusses how treatment is tailored to the whole patient, comparing TNF inhibitors, IL-17 inhibitors, and JAK inhibitors, while weighing risks such as infection, cardiovascular events, and long-term safety. Importance of Exercise and Integrative Care Exercise, physical therapy, and lifestyle interventions are essential components of treatment. While supplements and diet can support symptom relief, they are not substitutes for disease-modifying therapies. Managing Overlapping Conditions She highlights the importance of coordinating care for patients with related conditions such as psoriasis, uveitis, and inflammatory bowel disease, ensuring treatment choices address multiple disease pathways. Future Directions in Research Emerging research on the gut microbiome offers promising insights into new therapeutic targets, potentially transforming how axial spondyloarthritis is managed in the future. Key Takeaway Early recognition of inflammatory back pain is critical in axial spondyloarthritis. A combination of clinical awareness, appropriate imaging, and personalized treatment—including both pharmacologic and lifestyle approaches—can significantly improve patient outcomes and prevent long-term disease progression.

Addiction, Overstimulation, and Performance in Sports Psychiatry

In this episode of MD Newsline, Dr. Justin Morales, Addiction Psychiatry Fellow at Mass General Brigham Harvard Medical System, explores how our understanding of addiction has evolved from a simple reward-pathway model to a comprehensive biopsychosocial framework. Dr. Morales discusses substance use disorders alongside emerging behavioral addictions such as social media overuse, gaming, and binge behaviors. He explains how dopamine signaling, reward-based learning, and executive function circuits influence compulsivity and craving—and why modern overstimulation may blur the line between habit and addiction. The conversation also examines cannabis potency trends, co-occurring psychiatric conditions, sports psychiatry, and emerging neuromodulation treatments for addiction. Episode Highlights: The Biopsychosocial Model of Addiction Dr. Morales outlines the shift from a narrow neurochemical model to a holistic framework incorporating biology, psychology, and social environment. Treatment may involve medication, therapy, and social interventions working together rather than in isolation. Substance vs. Behavioral Addictions While behavioral addictions like social media overuse are not formally classified the same way as substance use disorders in DSM-5, clinicians can adapt similar criteria—such as functional impairment, compulsivity, and high-risk behaviors—to assess severity. Cannabis Potency and Psychiatric Risk Modern cannabis products are significantly more potent than in prior decades. Dr. Morales highlights growing concerns about high-THC exposure potentially contributing to psychosis and mood destabilization. Co-Occurring Mood Disorders Over half of individuals with substance use disorders have a co-occurring psychiatric condition. Dr. Morales discusses common treatment pitfalls—such as addressing depression without addressing substance use—and emphasizes integrated care. Digital Overstimulation and Dopamine Social media and gaming platforms leverage reward-based learning similar to substances. The brain adapts to chronic overstimulation, which may lead to reduced baseline motivation and mood flattening. Dopamine Detox: Myth or Medicine? Although strong research evidence is limited, reducing overstimulation may help the brain recalibrate toward homeostasis and improve natural reward sensitivity. Integrated Treatment for Multiple Addictions Dr. Morales explains how clinicians may treat different substances pharmacologically while addressing underlying psychological drivers—such as avoidance or emotional numbing—through unified therapy strategies. Sports Psychiatry and Identity Athletes face unique pressures tied to performance, injury, career transitions, and identity fusion. Substance use and mood disorders may emerge during times of injury or role changes. Youth Sports and Escalating Pressure With increasing financial and performance stakes at younger ages, adolescent athletes face heightened mental health risk before full neurodevelopment. Neuromodulation in Addiction Emerging treatments—including transcranial magnetic stimulation (TMS), deep brain stimulation (DBS), and vagus nerve stimulation (VNS)—target brain circuits involved in executive function and craving, particularly the prefrontal cortex. Executive Function and Craving Addiction involves planning, coordination, and decision-making processes—not simply impulsivity. Targeting prefrontal control circuits may influence compulsive behaviors and substance-seeking. Collaborative Care Model Effective addiction and sports psychiatry care requires collaboration among psychiatrists, psychologists, social workers, trainers, coaches, and family members to identify behavioral changes early and provide coordinated support. Key Takeaway Addiction in the modern era extends beyond substances to include digital and behavioral reinforcers embedded in everyday life. A biopsychosocial framework—combined with integrated treatment, executive function support, and collaborative care—offers the most effective approach for addressing substance use disorders and behavioral addictions alike.

Understanding Alzheimer's Disease: Biomarkers and Early Detection

In this episode of MD Newsline, Dr. Rudolph J. Castellani, a neuropathologist and Director of the Division of Neuropathology at Northwestern University, offers a deep dive into the biology, diagnosis, and ongoing controversies surrounding Alzheimer's disease. He explores how Alzheimer's is defined clinically and pathologically, the evolving role of biomarkers in early detection, and why modifying biomarkers has not yet translated into meaningful clinical improvement for patients. Dr. Castellani also discusses the promise and limitations of artificial intelligence, personalized medicine, and lifestyle interventions in Alzheimer's research and care. Episode Highlights Defining Alzheimer's Disease Dr. Castellani explains how Alzheimer's disease can be defined clinically—through progressive memory and cognitive decline—or pathologically, based on hallmark brain lesions such as amyloid plaques and neurofibrillary tangles identified post-mortem. These structural changes remain central to diagnosis but do not fully explain disease progression. The Role of Amyloid and Biomarkers Amyloid beta, a key component of senile plaques, can now be detected through cerebrospinal fluid testing, blood-based biomarkers, and PET imaging. Dr. Castellani discusses how biomarkers help identify disease presence earlier but raises important questions about whether amyloid is a driver of disease or merely an associated marker. Early Detection: Promise and Ethical Concerns While biomarkers allow detection before symptoms appear, Dr. Castellani highlights the ethical dilemma of diagnosing asymptomatic individuals. He questions whether early identification without effective intervention may increase anxiety without improving outcomes. Therapies and Clinical Trial Limitations New anti-amyloid therapies, including FDA-approved agents, show only marginal cognitive benefit in highly selected trial populations. Dr. Castellani emphasizes caution when extrapolating these results to broader, more diverse patient groups and underscores the potential risks and toxicities associated with these treatments. Artificial Intelligence and Predictive Modelling AI and machine learning may enhance predictive modeling by integrating biomarkers, genetics, and cognitive data. However, Dr. Castellani notes that prediction alone is insufficient without therapies that meaningfully alter disease progression. Age of Onset and Risk Factors Alzheimer's disease can present as early as a patient's 30s in rare genetic cases or later in life in sporadic forms. Dr. Castellani reviews known risk factors, including APOE genotype, hypertension, diabetes, hearing loss, and traumatic brain injury, while stressing that many associations remain poorly understood. Personalized Medicine and Genetic Counseling Genetic testing—particularly for APOE and pathogenic mutations—plays a role in personalized risk assessment. Dr. Castellani emphasizes the importance of careful counseling, as not all individuals want or benefit from knowing their genetic risk. Supportive and Interdisciplinary Care With no curative treatments available, interdisciplinary care involving neurologists, neuropsychologists, and social workers is essential. Dr. Castellani highlights the importance of caregiver support, expectation management, and access to specialized centers. Lifestyle and Prevention Although lifestyle changes may not alter the underlying biology of Alzheimer's disease, healthy diet, exercise, and reducing inflammation and oxidative stress can improve quality of life and overall health. Key Takeaway Dr. Castellani underscores that while biomarkers and amyloid-focused therapies dominate current Alzheimer's research, they have not yet delivered meaningful clinical improvement. A broader research approach—beyond amyloid—combined with realistic expectations, ethical care, and strong support systems is essential for patients and families navigating Alzheimer's disease.
