Cerebral Palsy
Overview Cerebral palsy is a non-Progressive neurological disorder. Usually with significant motor component. Clinical presentation overtime changes due to increased developmental challenges.Cerebral palsy (CP) is the most common physical disability in childhood. Prevalence is about 1 – 3/ 1000 live births. Cerebral palsy can affect: Cerebral cortex – causing spasticity Basal ganglia – causing dyskinesia…
View topic ↗Urinary Incontinence
Overview Urinary incontinence is an important condition because it causes significant distress. Approximately 15% of the general female adult population have a significant problem with urinary incontinence. Urinary incontinence: Defined as the condition in which there is invontary loss of urine, which can be objectively demonstrated and which is a social or hygienic problem. Stress…
View topic ↗Iron Deficiency Anaemia
Overview In the clinical setting, iron deficiency is the most common cause of anaemia. Iron Deficiency is lack of iron in the body resulting from inadequate iron intake, increased iron loss and increased iron demand which can lead to anaemia. Iron is an integral part of haemoglobin the oxygen carrying protein. Without iron, oxygen is unable to…
View topic ↗Bowel Obstruction
Overview Bowel obstruction is a blockage of intestinal contents, either mechanical (e.g., adhesions, hernias, malignancy) or functional (e.g., ileus), leading to impaired transit, proximal dilation, and downstream complications including ischaemia and perforation if untreated. Key features of bowel obstruction include colicky abdominal pain, distension, nausea with bilious or faeculent vomiting, obstipation, initially high-pitched then absent…
View topic ↗Adult onset Still's Disease
Overview Adult Onset Still’s Disease (AOSD) is a complex multisystemic autoinflammatory disease characterised by recurrent episodes of spiking fever (> 39–40°C), pink–salmon transient skin rash, and the presence of arthralgia or polyarthritis. First described by Eric Bywaters in 1971 it closely resembles systemic onset juvenile idiopathic arthritis (Still’s disease). retrospective observational study in Japan found…

Overview Parturition Physiology Preterm: defined as babies born alive before 37 weeks of pregnancy are completed. Term: defined as babies born alive after 37 weeks and before 42 weeks Postterm (induced for labour): defined as babies born alive after 42 weeks. Birthweight Low birth weight: <2500g regardless of age Very low birth weight: <1500g regardless of…
View topic ↗Vitamin B12 Deficiency Anaemia
Overview Vitamin B 12 (cobalamin) deficiency is a common cause of megaloblastic anemia, a variety of neuropsychiatric symptoms, and elevated serum homocysteine levels, especially in older persons. The recognition and treatment of vitamin B 12 deficiency is critical since it is a reversible cause of bone marrow failure and demyelinating nervous system disease. Anaemia (Anemia): The…

Congenital Hip Dysplasia
Explore hip dysplasia, its developmental causes, clinical signs, and diagnostic approaches in both infants and adults. This video also covers the pathophysiology and treatment options, including bracing and surgical correction.

Understanding Vitamin B12 metabolism
Learn how vitamin B12 is absorbed, transported, and utilized in the body, highlighting its essential roles in red blood cell formation and nervous system function. This video explains the key steps in B12 metabolism, including intrinsic factor binding, absorption in the ileum, and clinical implications of deficiency.

Compensatory Mechanisms of (Medical) Shock
Discover the body's compensatory mechanisms during medical shock, including how the cardiovascular and endocrine systems respond to maintain perfusion and blood pressure. This video explains key processes like sympathetic activation, vasoconstriction, tachycardia, and fluid retention aimed at stabilizing circulation.
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.
“The notes I make during his videos help me retain everything better.
“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.
Lambert-Eaton Myasthenic Syndrome
Overview Lambert–Eaton myasthenic syndrome (LEMS) is a rare autoimmune disorder of the presynaptic neuromuscular junction. It causes impaired acetylcholine release, producing the characteristic triad of proximal muscle weakness, reduced reflexes and autonomic dysfunction. LEMS may occur as a paraneoplastic syndrome—most commonly associated with small-cell lung cancer (SCLC)—or as a non-tumour-associated autoimmune disorder. Neuromuscular junction: connection…
