Liver Cirrhosis
Overview Cirrhosis is the advanced stage of chronic liver injury characterised by widespread fibrosis, regenerative nodules and distortion of normal hepatic architecture. This causes two major consequences: Portal hypertension Reduced hepatic function Cirrhosis may remain asymptomatic for years before progressing from a compensated to a decompensated stage. Compensated cirrhosis: cirrhosis without major clinical complications. Decompensated…

Bipolar Disorder
Overview Bipolar disorder, previously termed manic depression, is a psychiatric diagnosis characterised by abnormally elevated or irritable mood episode(s) accompanied by disruptive symptoms of distractibility, indiscretions, grandiosity, flight of ideas, hyperactivity, decreased need for sleep, and talkativeness. It is well known that bipolar disorder carries with it high mortality and morbidity rates. The lifetime risk…

Interstitial Lung Disease
Overview Interstitial Lung Disease is also known as Diffuse Parenchymal Lung Disease (DPLD). A Heterogeneous collection of restrictive lung conditions (>100) that primarily (or at least initially) disrupt the pulmonary interstitium. Interstitial Lung Disease (ILD) are grouped together as they share similar pathophysiological mechanisms, clinical features and radiological findings. Pulmonary Interstitium: Intervening structural tissue between the alveoli space and pulmonary…

Osteomalacia / Rickets
Overview Osteomalacia (adults) and rickets (children) are disorders of impaired bone mineralisation leading to soft, poorly mineralised bone. It arises when there is insufficient calcium–phosphate supply to the mineralising matrix due to vitamin D deficiency, calcium deficiency, phosphate deficiency (often FGF23-mediated). Nutritional rickets still occurs worldwide, while hypophosphataemic forms (e.g., XLH, tumour-induced osteomalacia) are rarer…

Asthma (Adults)
Clinical features of asthma such as dyspnoea, chest tightness and wheezing can mimic other respiratory conditions. It is important to take a careful history and examination and ideally demonstrate reversible airflow obstruction. Other clinical features of asthma arise during periods of bronchoconstriction (ie. exercise, smoking, stress, cold air). Exacerbation of asthma confounds the breathing difficulty, cough and wheeze in patients.

Chronic Peripheral Arterial Disease: Intermittent Claudication
Overview Peripheral arterial disease (PAD) is an atherosclerotic disorder that reduces blood flow to the limbs, most often the legs. Intermittent claudication is exertional muscle discomfort caused by a mismatch between oxygen supply and demand; it is reproducibly triggered by walking and usually resolves within about 10 minutes of rest. Although claudication is a limb…

Acute Liver (Hepatic) Failure
Overview Acute liver failure (ALF) is a rare, rapidly evolving syndrome of severe hepatocellular injury with loss of hepatic function. Patients can deteriorate from apparently mild illness to encephalopathy and multiorgan failure within days. Prompt recognition, cause-specific treatment and early transplant-centre involvement are essential. These notes describe adult ALF; paediatric diagnostic criteria differ. [1–4] Acute…

Good places to begin
Explanations learners return to.
Neurology – Divisions of the Nervous System
Learn about the major divisions of the nervous system, including the central and peripheral components, and how they coordinate body functions. This video explains the roles of the somatic and autonomic systems, highlighting their structure and function in regulating voluntary and involuntary actions.
Anatomy of the Hip Joint | Capsule, Muscles & Clinical Relevance Explained
Learn the detailed anatomy of the hip joint in this concise medical video, covering the hip joint capsule, key muscles including iliopsoas, gluteals, and short external rotators, and relevant clinical conditions such as hip dislocations, vascular necrosis and examination techniques. This video is ideal for medical students, physiotherapists, orthopaedic trainees, and anyone studying musculoskeletal anatomy.…
MHC class II processing – antigen presentation mechanism
Learn how MHC II molecules present extracellular antigens to helper T cells, playing a key role in activating adaptive immune responses. This video explains the antigen processing steps, including endocytosis, peptide loading in endosomes, and the involvement of the invariant chain and HLA-DM.
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.
Jessica Payne-Burnett
Medical Student, Charles Sturt University
“The notes I make during his videos help me retain everything better.
Ayesha RaiStudent, Islamabad Medical and Dental College
“The drawings are amazing and super easy to remember.

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…
