Guillain–Barré Syndrome
Overview Guillain-Barré Syndrome (GBS) is an acute, immune-mediated polyneuropathy typically triggered by a preceding gastrointestinal or respiratory infection. It is characterised by an autoimmune attack on the peripheral nerves, leading to mainly demyelination but also axonal degeneration, which impairs nerve conduction and causes muscle weakness and paralysis. GBS affects about 1–2 per 100,000 people annually.…

Patellar Tendinopathy (Jumper’s Knee)
Overview Patellar tendinopathy, commonly called jumper’s knee , is a load-related disorder of the patellar tendon. It typically causes localised anterior knee pain at the tendon’s attachment to the inferior pole of the patella. The condition is particularly associated with sports involving repeated jumping, landing, acceleration and rapid changes of direction, such as basketball, volleyball…

Infective Endocarditis
Overview Infective endocarditis is a condition which occurs in the setting of bacteraemia whereby endothelial surfaces of the heart, such as valvular structures, become infected. It can present acutely or subacutely, and is often associated with fevers, new heart murmurs, constitutional symptoms and embolic phenomena. The classical organism associated is Staphylcoccus aureus, however there are…

Osteonecrosis of the Hip
Overview Osteonecrosis of the hip, usually referring to osteonecrosis of the femoral head (ONFH), is a progressive disorder caused by compromised subchondral blood supply leading to death of osteocytes and marrow elements, failed structural repair, subchondral fracture, femoral head collapse, and eventually secondary hip osteoarthritis. [1-4] It most often affects younger to middle-aged adults, commonly…

Brain Tumour
Overview Brain tumours: refers to a mixed group of neoplasms originating from intracranial tissues and the meninges with degrees of malignancy ranging from benign to aggressive. Classification WHO Classification of Primary Brain Tumors Neuroepithelial tumors Astrocytic tumors Oligodendroglial tumors Oligoastrocytic tumors Ependymal tumors Choroid plexus tumors Neuronal and mixed neuronal-glial tumors Pineal tumors Embryonal tumors…

Acute Cholecystitis
Overview Acute cholecystitis is acute inflammation of the gallbladder, usually caused by a gallstone obstructing the cystic duct. Persistent obstruction causes gallbladder distension, inflammation and possible secondary bacterial infection. Most cases are calculous, while acalculous cholecystitis occurs mainly in critically ill or severely immunocompromised patients. Cholecystectomy: surgical removal of the gallbladder. Calculous cholecystitis: gallbladder inflammation…

Polyarteritis Nodosa
Overview Polyarteritis Nodosa (PAN) is a necrotising vasculitis that affects medium-sized muscular arteries, leading to transmural inflammation, fibrinoid necrosis, and subsequent aneurysm formation or ischemia. It does not involve arterioles, capillaries, or venules, and is not associated with ANCA. PAN can affect any organ except the lungs. It typically presents in middle-aged adults, more commonly…

Good places to begin
Explanations learners return to.
Primary Myelofibrosis – Overview (presentation, pathophysiology, investigation, treatment)
Learn about Primary Myelofibrosis, a chronic myeloproliferative disorder characterized by bone marrow fibrosis, splenomegaly, and cytopenias. This video covers its clinical presentation, underlying pathophysiology, diagnostic approach, and current treatment strategies.
Liver Cirrhosis (Causes II)
Continue learning about the causes of liver cirrhosis with a focus on autoimmune, genetic, and biliary conditions. This video explains how these less common factors contribute to progressive liver damage and scarring.
Human Metabolism Map IV – Acetyl Coa Transport
Explore the role of Acetyl-CoA Transport in cellular metabolism with this video from the Human Metabolism Map series. Learn how Acetyl-CoA moves across compartments to support fatty acid synthesis and energy production—essential for biochemistry exams and clinical understanding.
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.
Reem Mohamed Khair Abdalrazig
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.
Cervical Radiculopathy
Overview Cervical radiculopathy is dysfunction of a cervical nerve root caused by irritation or compression as it leaves the spine. It commonly produces pain radiating from the neck into one arm, sometimes with paraesthesia, numbness, weakness or altered reflexes. A disc herniation or degenerative narrowing of the neural foramen is a common cause. Diagnosis is…
