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.…

Blount’s Disease
Overview Blount's disease, also called tibia vara, is a developmental growth disorder of the posteromedial proximal tibial physis. Asymmetric growth produces progressive genu varum centred below the knee, commonly with procurvatum, internal tibial torsion and relative shortening. It differs from physiological bowing because the deformity persists or progresses rather than following normal spontaneous correction.¹,² Early-onset…

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…

Pernicious Anaemia
Overview Pernicious Anaemia is a condition where there is lack of intrisinc factor, a glycoprotein responsible for the absorption of Vitamin B12. Vitamin B12 (Cobalamin) is an essential vitamin responsible for many physiological process in our body. Vitamin B12 deficiency causes megaloblastic anaemia and maybe accompanied by neurological abnormalities. Aetiology Pernicious Anaemia is associated with…

Bronchiectasis
Overview Bronchiectasis was a common disabling and fatal condition in the pre-antibiotic era and remains more common in medically underserved regions of the world. Irreversible dilatation of airways due to in ammatory destruction of airway walls resulting from persistently infected mucus. Bronchiectasis usually affects medium sized airways Bronchiectasis: Bronchiectasis is the permanent dilation of bronchi…

Pelvic Inflammatory Disease
Overview Pelvic inflammatory disease (PID) comprises a spectrum of inflammatory disorders of the upper female genital tract, including any combination of endometritis, salpingitis, tubo-ovarian abscess, and pelvic peritonitis. Causative organisms are either sexually transmitted (such as C trachomatis , N gonorrhoeae , Mycoplasma genitalium ) or endogenous vaginal organisms (for example, Bacteroides species) that ascend…

Shingles (Herpes Zoster)
Overview Shingles is reactivation of latent varicella-zoster virus (VZV) following previous chickenpox or, less commonly, varicella vaccination. After primary infection, VZV remains dormant in the dorsal-root or cranial-nerve ganglia. Reactivation occurs when VZV-specific cell-mediated immunity declines. In Australia, incidence is approximately 560 cases per 100,000 people annually and increases markedly after age 50. Lifetime risk…

Cerebral Palsy – (DETAILED) Overview
This detailed video on Cerebral Palsy covers its causes, types, clinical features, and management strategies. Gain a comprehensive understanding of this neurological disorder essential for healthcare professionals and students.
Systemic Lupus Erythematosus (SLE) – signs and symptoms, pathophysiology, investigations, treatment
Systemic Lupus Erythematosus (SLE) is a complex autoimmune disease that affects multiple organs with symptoms like fatigue, rash, and joint pain. This video explains its underlying pathophysiology, diagnostic approaches, and current treatment strategies.
Thrombocytopaenia (low platelets) Overview – platelet physiology, classification, pathophysiology
Learn the basics of thrombocytopaenia, including platelet physiology, classification, and the key mechanisms behind low platelet counts. This video breaks down common causes and how they affect clotting and overall hemostasis.
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.

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…
