Sjögren’s Syndrome
Overview Sjögren’s Syndrome is a chronic, systemic autoimmune disorder characterized by lymphocytic infiltration and destruction of exocrine glands, primarily affecting the salivary and lacrimal glands, leading to dry mouth (xerostomia) and dry eyes (keratoconjunctivitis sicca). It commonly affects middle-aged women, with a female:male ratio of approximately 9:1. It can be primary (isolated) or secondary (associated…

Alzheimer's Disease
Overview Alzheimer disease is characterised by an insidious onset of symptoms with initial forgetfulness progressing over time to profound memory impairment with accompanying dysphasia, dyspraxia and personality change. Dementia: Clinical syndrome that is characterised by a progressive deterioration in cognition with resulting decline in function. Alzheimer disease: Characterised by an insidious onset of symptoms with initial…

Chronic Exertional Compartment Syndrome (Exercise-induced Compartment Syndrome)
Overview Chronic compartment syndrome (also known as chronic exertional compartment syndrome or exercise induced compartment syndrome) is an exertional condition in which repetitive activity causes transiently elevated pressure within a closed myofascial compartment, leading to ischemic pain, tightness, and sometimes neurologic symptoms that predictably begin with exercise and abate with rest. It most often affects…

Cardiac Sarcoidosis
Overview Cardiac sarcoidosis is an inflammatory heart disease caused by myocardial infiltration with non-necrotising granulomas. Inflammation may subsequently resolve, recur, or progress to permanent fibrosis. The disease is often patchy and may affect the conduction system, ventricular myocardium, papillary muscles, valves, pericardium, or coronary microcirculation. 1 Cardiac involvement may occur as part of multisystem sarcoidosis…

Delirium
Overview Delirium is a neuropsychiatric syndrome characterized by a disturbance in consciousness and cognition. It typically presents as an acute confusional state , with inattention as its core symptom. Unfortunately, the diagnosis of delirium is often delayed or missed, especially the hypoactive form that is common in older persons. Aetiology & Risk Factors Aetiology A…

Piriformis Syndrome
Overview Piriformis syndrome describes buttock pain attributed to irritation or entrapment of the sciatic nerve near the piriformis muscle. Pain may radiate down the back of the thigh and resemble lumbar sciatica. Prolonged sitting often aggravates symptoms. Diagnosis can be difficult because buttock and leg pain have several possible causes and there is no single…

Reactive Arthritis
Overview Reactive arthritis is a seronegative spondyloarthropathy that occurs after a genitourinary or gastrointestinal infection, typically presenting as an asymmetric oligoarthritis, often with associated conjunctivitis and urethritis (formerly Reiter’s syndrome). It most commonly affects young adults aged 20–40 and shows a strong association with HLA-B27. Incidence is estimated at 30–40 per 100,000, with higher rates…

Good places to begin
Explanations learners return to.
Part II – Inflammation
Delve deeper into inflammation by examining the chemical mediators that drive the inflammatory process, such as histamine, prostaglandins, and cytokines. This video explains how these molecules coordinate vascular changes, immune cell recruitment, and resolution of inflammation.
PART II – Pneumonia (Transmission, Causative Agents, Investigations, Management)
This video dives into Part II of Pneumonia, focusing on how it's transmitted, key bacterial and viral causative agents, and the clinical workup. Learn the essential investigations and management strategies for effective diagnosis and treatment.
Nephrology – Kidney Physiology Overview
Explore the fundamental functions of the kidneys, including filtration, reabsorption, secretion, and urine formation. This video provides a clear overview of kidney physiology and how these processes maintain fluid, electrolyte, and acid-base balance in the body.
Our mission
Medical science is complex. Understanding it should feel possible.
Armando Hasudungan turns difficult medical science into clear visual explanations and connected learning experiences—so learners can see the whole picture, remember what matters and find a clearer way forward.
See it clearly
Turn abstract processes and invisible relationships into something the learner can picture.
Connect the pieces
Build understanding around how concepts fit together—not a pile of isolated facts.
Make it useful
Help learners move from explanation to recall, revision and the next logical step.
What clarity feels like
When the topic stops being a blur.
Learners do not come back because the subject became easy. They come back because the explanation gave them a picture they could work with.
“Armando's teaching style gives me the foundational knowledge.

Coming soon: the AH study platform
The explanation is only the start.
The free library helps you find a clear explanation. The AH platform is being built to help you connect the resources, follow a clearer path and check what actually stuck.
- Watch in a focused, ad-free study environment.
- Move between connected videos, notes, diagrams and questions.
- Know what belongs next instead of rebuilding the study path yourself.
- Test your understanding while the topic is still fresh.
New and worth a look
Keep building the picture.
Femoroacetabular Impingement Syndrome
Overview Femoroacetabular impingement syndrome (FAIS) is a motion-related clinical disorder of the hip in which symptoms and clinical signs occur in association with characteristic femoral and/or acetabular morphology. The accepted diagnostic concept is a triad of symptoms, clinical signs and imaging findings ; bone morphology alone does not establish the syndrome. Patients commonly present with…
