Marfans Syndrome
Overview Marfan's Syndrome is one of the most common inherited disorders of connective tissue. Marfan syndrome is a hereditary disease affecting connective tissues in the body, resulting in symptoms such as aortic dissection and musculoskeletal deformities. However, no family history of Marfan's does not exclude the diagnosis as 30% can occur through gene mutation. Marfan syndrome:…

Obstructive Sleep Apnoea
Overview Sleep apnea syndrome is an extremely common medical disorder associated with important morbidity. Sleep Apnea and can be classified as: Obstructive Sleep Apnea – is the most common, characterized by repetitive, intermittent collapse of the upper (pharyngeal) airway during sleep, which causes apnoeic episodes terminated by partial arousal Central Sleep Apnea - characterised by repetitive absent or diminished…

Pseudogout: Calcium Pyrophosphate Deposition Disease
Overview Pseudogout, more accurately known as calcium pyrophosphate deposition disease (CPPD), is a crystal arthropathy characterized by the deposition of calcium pyrophosphate dihydrate crystals in articular cartilage and soft tissues, leading to joint inflammation. It most commonly affects elderly individuals, especially over the age of 60, with a slight female predominance. Clinically, it often mimics…

Anklylosing Spondylitis (AS)
Overview Ankylosing spondylitis (AS) is a chronic, progressive inflammatory arthritis that primarily affects the axial skeleton, especially the sacroiliac joints and spine. It is a subtype of the seronegative spondyloarthropathies and is characterised by inflammatory back pain, morning stiffness, and eventual spinal fusion in severe cases. AS often presents in young adults, typically males, and…

Urinary Tract Infection
Overview Infection of the urinary tract is common and more so in women (due to shorter urethra and hormonal changes). UTIs may be classified as either a lower (Cystitis, urethritis and Prostatitis) or upper UTI (pyelonephritis). The main causative agents are bacteria such as E-coli. A lower UTI can progress to an upper UTI causing systemic symptoms…

Nephrotic Syndrome
Overview Nephrotic syndrome is a relatively rare but important manifestation of kidney disease.Nephrotic syndrome classically presents with heavy proteinuria , minimal hematuria, hypoalbuminemia, hypercholesterolemia, edema , and hypertension. In general, all patients with hypercholesterolemia secondary to nephrotic syndrome should be treated with lipid-lowering agents because they are at increased risk for cardiovascular disease. Nephrotic syndrome…

Rett Syndrome
Protein Structure and Function – Overview
Proteins are the molecules that do most of the work in the body—learn protein structure, function, and clinical relevance. In this clear, engaging video you'll discover what proteins are (chains of amino acids linked by peptide bonds), why amino acid order dictates shape and function, and how folding produces primary, secondary (alpha helices, beta sheets),…
Endocytosis
Dive into the mechanisms of endocytosis, including phagocytosis, pinocytosis, and receptor-mediated uptake, in this concise, high-yield explainer. Ideal for students preparing for exams like the USMLE, MCAT, or NEET who need to solidify their understanding of cellular transport.
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.
Chronic inflammatory demyelinating polyneuropathy (CIDP)
Overview Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired immune-mediated disorder of peripheral nerves and nerve roots, causing demyelination, impaired nerve conduction, weakness, sensory disturbance and reduced or absent reflexes. Typical CIDP causes progressive or relapsing symmetrical proximal and distal weakness with sensory loss developing over at least 8 weeks . This time course helps…
