Multiple Sclerosis
"Each patient ought to feel somewhat the better after the physician's visit irrespective of the nature of the illness." -Warfield Theobald Longcope Overview Multiple sclerosis (MS) is defined as an inflammatory demyelinating disease characterised by the presence of episodic neurological dysfunction in at least 2 areas of the CNS (brain, spinal cord, and optic nerves)…

Fibromyalgia
Overview Fibromyalgia is a chronic, nociplastic pain condition characterised by widespread pain with prominent fatigue, sleep disturbance, and cognitive symptoms, reflecting altered central pain processing rather than tissue injury. Global prevalence is ~2–4%, higher in women, ages 20–60, and in those with mood/sleep disorders, obesity, low socioeconomic status, and comorbid rheumatic disease. Major complications include…

Angina Pectoris
Overview Angina Pectoris refers to the pain caused by myocardial ischaemia. Myocardial Ischaemia is usually caused by stenosis within the vessel decreasing blood flow to the muscle, but it can be caused by tachycardia, anaemia, aortic stenosis, left ventricular hypertophy and many other disease. Angina "latin choking". Angina Pectoris: Pain caused by myocardial ischaemia (not myocardial…

Otitis Externa
Overview Otitis externa is an acute or chronic inflammation of the external auditory canal, which extends from the tympanic membrane to the pinna. It is predominantly a localized bacterial infection caused by a breakdown in the natural protective barriers of the ear canal—namely cerumen, an acidic pH, and an intact epithelial lining. Frequently referred to…

Myelofibrosis
Overview Myelofibrosis is a type of myeloproliferative diseasecharacterized by clonal myeloid expansion, followed by progressive fibrous connective tissue deposition in the bone marrow, resulting in bone marrow failure. Clonal evolution can also occur, with an increased risk of transformation to acute myeloid leukemia. In addition, disabling constitutional symptoms secondary to the high circulating levels of…

Parturition and Routine Care
Overview Parturition Physiology Preterm: defined as babies born alive before 37 weeks of pregnancy are completed. Term: defined as babies born alive after 37 weeks and before 42 weeks Postterm (induced for labour): defined as babies born alive after 42 weeks. Birthweight Low birth weight: <2500g regardless of age Very low birth weight: <1500g regardless of…

Acute Pancreatitis
Overview Acute pancreatitis is sudden inflammation of the pancreas caused by premature activation of pancreatic digestive enzymes within the gland. It ranges from a mild, self-limiting illness to severe necrotising pancreatitis with persistent organ failure. The most common causes are gallstones and alcohol, although hypertriglyceridaemia, medicines, procedures and metabolic disorders are also important. Acute Pancreatitis:…

Good places to begin
Explanations learners return to.
Compensatory Mechanisms of (Medical) Shock
Discover the body's compensatory mechanisms during medical shock, including how the cardiovascular and endocrine systems respond to maintain perfusion and blood pressure. This video explains key processes like sympathetic activation, vasoconstriction, tachycardia, and fluid retention aimed at stabilizing circulation.
Pulomary Collapse Atelectasis
Learn the key concepts of pulmonary collapse (atelectasis), including its types, causes, and clinical implications. This video offers a clear breakdown of pathophysiology and diagnostic clues essential for exams and clinical practice.
Hypertrophic cardiomyopathy – signs and symptoms, causes, pathophysiology, treatment
Explore hypertrophic cardiomyopathy, a genetic heart disorder marked by abnormal thickening of the myocardium that can impair cardiac function. This video explains its causes, symptoms like chest pain and syncope, the underlying pathophysiology, and treatment approaches to reduce risk and manage symptoms.
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.

Student, Neelain University
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.
Aortic Aneurysm
Overview An aortic aneurysm is a pathological dilatation of the aorta caused by weakening of the arterial wall. It may involve the aortic root, ascending aorta, arch, descending thoracic aorta, thoracoabdominal aorta or abdominal aorta. Most aortic aneurysms are asymptomatic and are discovered incidentally or through screening. Progressive enlargement increases the risk of rupture, dissection,…
