Migraine, the Trigeminovascular Pathway, and CGRP
Learn how trigeminal pain pathways and CGRP contribute to migraine, why aura is a distinct phenomenon, and how a practical headache diary can improve a clinical conversation.
Multiple Sclerosis: Demyelination and Changing Nerve Signals
Explore how inflammation affects myelin and axons in multiple sclerosis, why symptoms vary, and how current diagnostic evidence is interpreted in a clinical setting.
Chronic Rhinosinusitis With Nasal Polyps: Phenotype and Endotype
Separate the visible nasal-polyp phenotype from eosinophilic or type 2 inflammatory pathways, and understand what those patterns can and cannot establish.
Diabetic Retinopathy Screening: Timing, Exams, and Treatment
A source-grounded guide to screening schedules by diabetes type, dilated examination, additional imaging, and treatment options.

Understand the IL-23/IL-17–keratinocyte connection and keep skin findings, joint symptoms and treatment safety checks distinct.
Celiac Disease: Gluten Immunity and Preparing for Testing
Understand the limits of TG2/HLA mechanisms, discuss gluten intake before testing, and prepare a useful consultation record.
Cushing Syndrome: How Excess Cortisol Relates to Body and Muscle Changes
Cushing syndrome is prolonged exposure to excess cortisol. This guide separates medication-related and endogenous causes, explains metabolic and tissue changes, and outlines why diagnosis requires clinical evaluation.
Gout and Hyperuricemia: Diagnosis, Urate Targets and Records
Distinguish blood urate from joint crystals, apply ACR 2020 recommendations to their intended groups and prepare a record of results and flares.

Distinguish steatosis, inflammation and fibrosis, understand FIB-4 limits, and prepare records using the scope of the 2024 society guidelines.
Obstructive Sleep Apnea: Tests, AHI and CPAP Records
Distinguish airway obstruction from PAP support, interpret test results in context and prepare a useful record of device use and problems.
Type 1 Diabetes: Autoimmunity and Islet Autoantibody Testing
An evidence-bounded guide to beta cells, autoimmunity, what islet autoantibody tests can show, and why a positive result is not a diagnosis.
How Cortisol and Aldosterone Deficiency Differ in Addison Disease
An explanation of how primary adrenal damage affects cortisol, aldosterone, and fluid and electrolyte regulation. Symptoms are nonspecific; this is not a diagnostic or treatment guide.
Atopic Dermatitis and the Skin Barrier: Moisture Loss and Care Limits
How barrier changes relate to moisture loss and the itch–scratch cycle, and what specialist guidance supports about care and its limits.
Atrial Fibrillation, Left Atrial Appendage Clots, and Stroke Risk
Atrial fibrillation can disrupt coordinated atrial contraction, allowing blood to pool and raising the possibility of clot-related stroke. This guide explains the left atrial appendage and why clinical risk assessment is not a score-only rule.
Caffeine at Adenosine Receptors: Connecting Mechanism and Intake Records
How caffeine antagonizes adenosine A1 and A2A receptors, and how label amounts, timing, and sleep observations fit an intake record. Neither the mechanism nor a label total establishes an individual safe amount.
