Schizophrenia

Overview Schizophrenia is a complex syndrome often presenting in late teens/early 20s with positive, negative and cognitive symptoms. Positive symptoms include behaviours and thoughts that are not normally present (psychosis). Negative symptoms include social withdrawal and affective flattening. Finally, cognitive symptoms are expressed as a broad set of cognitive dysfunction. The average lifetime prevalence of…

Aortic Stenosis

Overview Aortic valve stenosis is characterised by obstruction of left ventricular outflow, resulting in inadequate cardiac output, decreased exercise capacity, heart failure, and death from cardiovascular causes. Mild to moderate aortic stenosis is usually a symptomatic, but occasionally can be found on routine examination Locations of stenosis – Valvular (common), supravalvular and subvalvular Aortic Stenosis…

Complement Deficiencies

Overview Complement deficiencies are rare primary immunodeficiencies resulting from inherited absence or dysfunction of complement proteins, regulators, or receptors. They predispose to recurrent bacterial infections, autoimmune disease (particularly systemic lupus erythematosus–like syndromes), and in some cases angioedema. Complement proteins play a central role in innate immunity by opsonisation, chemotaxis, and direct lysis of pathogens via…

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.…

Neonatal Respiratory Distress Syndrome

Overview Neonatal respiratory distress syndrome (RDS) , previously called hyaline membrane disease, is a disorder caused primarily by pulmonary surfactant deficiency and structural lung immaturity. It occurs mainly in premature infants and presents shortly after birth with tachypnoea, grunting, chest recession and increasing oxygen requirements. Severity increases as gestational age decreases. Neonatal RDS is different…

Pulmonary Sarcoidosis

Overview Sarcoidosis is a multisystem granulomatous disease of unknown cause, characterised by the formation of non‑caseating granulomas in affected organs. Pulmonary involvement occurs in ~90% of patients, making it the most common manifestation. Global prevalence varies widely (e.g., 3.7/100,000 in Japan vs. 28.2/100,000 in Finland), with higher rates in Black Americans and Northern Europeans. Peak…

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.

01

See it clearly

Turn abstract processes and invisible relationships into something the learner can picture.

02

Connect the pieces

Build understanding around how concepts fit together—not a pile of isolated facts.

03

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.

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.

Cerebral Aneurysm

Overview Cerebral (Intracranial) aneurysm is a focal dilation of an intracranial artery due to weakness of the arterial wall. It occurs in roughly 1-5% of adults and can lead to permanent disability. The most common type is a saccular “berry” aneurysm. Most common location is anterior communicating artery.  Cerebral aneurysms are typically asymptomatic until rupture,…
