Dementia
Overview Dementia is a disorder that is characterized by impairment of cognition, typically involving memory and at least one other cognitive deficit, such as aphasia, apraxia, agnosia, or disturbance in executive functioning. These must represent a decline from previous level of function and be severe enough to interfere with daily function and independence. Decrease in intellectual…

Takayasu Arteritis
Overview Takayasu arteritis is a rare, chronic large-vessel vasculitis primarily affecting the aorta and its major branches, leading to stenosis, occlusion, or aneurysm formation. It most commonly affects young women (<40 years), particularly of Asian descent. The global incidence is estimated at 1–2 per million per year, with a female predominance (F:M ~9:1). It is…

Lateral and Medial Elbow Tendinopathy (Epicondylitis)
Overview Medial and lateral elbow tendinopathies are common overuse injuries affecting the common flexor and extensor tendon origins at the elbow, respectively. Commonly known as Golfer's Elbow (medial) and Tennis Elbow (lateral), these conditions are primarily degenerative (tendinosis) rather than inflammatory (tendinitis), resulting from repetitive microtrauma and failed healing responses. Lateral Elbow Tendinopathy (Tennis Elbow…

Goodpasture Syndrome (Anti-GBM disease)
Overview Goodpasture syndrome, now more precisely termed anti-glomerular basement membrane (anti-GBM) disease , is a rare autoimmune small-vessel vasculitis affecting lungs and kidneys, typically manifesting with diffuse alveolar hemorrhage and rapidly progressive glomerulonephritis. Microscopic polyangiitis (MPA) has an estimated incidence of approximately 0.5 to 1.8 cases per million per year. It demonstrates a bimodal age…

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…

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…

Developmental Hip Dysplasia
Overview Developmental Dyplasia of the hip (DDH) is previously known as congenital dislocation of the hip (however name changed as some of the hip problems develop after birth). Spectrum of condition related to development of the hip in infants and young children. Includes abnormal development of the acetabulum and proximal femur + mechanical instability of the hip joint. Usually involves…

Achalasia (esophageal) – signs and symptoms, pathophysiology, investigations and treatment
Achalasia is a rare disorder that results from progressive destruction of ganglion cells in the myenteric plexus of the oesophageal wall. The destruction of these cells leads to the inability of the lower oesophageal sphincter to relax, and leads to the loss of peristalsis of the distal oesophagus. As a result there is dilatation of…
Immunology – Innate Immunity (Toll-Like Receptors)
Discover the role of Toll-Like Receptors (TLRs) in innate immunity with this immunology video, covering how TLRs recognize pathogens and trigger immune responses. Perfect for exams and clinical prep, learn key TLR types, their ligands, and downstream signaling pathways.
Quadriceps muscle – Clinical Anatomy
Learn the clinical anatomy of the quadriceps muscle group, including its structure, function, and role in knee extension and stability. This video highlights the individual muscles, their innervation, common injury sites, and relevance in physical examination and rehabilitation.
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.
Juvenile Idiopathic Arthritis (JIA)
Overview Juvenile Idiopathic Arthritis (JIA) is an umbrella term encompassing a heterogeneous group of chronic inflammatory arthritides of unknown etiology presenting in children under 16 years of age. It represents the most common chronic pediatric rheumatic disease, with an estimated prevalence of 1 in 1,000 children. To meet the diagnostic criteria, arthritis must persist for…
