Brain Abscess
Overview A brain abscess is a focal, encapsulated suppurative infection originating within the brain parenchyma. It begins as a localized area of unencapsulated parenchymal inflammation (cerebritis) that evolves over days to weeks into a pus-filled core surrounded by a vascularized collagen capsule. Despite significant advances in neuroimaging, stereotactic neurosurgery, and broad-spectrum antimicrobial therapy, a brain…

Acute Heart Failure
Overview Acute Heart Failure (AHF) is a life-threatening medical emergency defined as the rapid onset or sudden worsening of symptoms and signs of heart failure. It results from severe cardiac dysfunction leading to inadequate systemic cardiac output, elevated intracardiac pressures, or both. AHF can present either as de novo heart failure in a patient without…

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…
