Chronic Kidney Disease
Overview CKD is responsible for a substantial burden of illness and premature death. The kidneys are basically not working as good. Always assume a ↓ eGFR represents acute kidney injury until proven otherwise. Acute Kidney Injury: Rapid reduction in kidney function over hours to days, as measured by serum urea and creatinine and leading to a…

Parkinson Plus Syndrome
Overview Parkinson-Plus syndromes (also known as atypical parkinsonism ) are a heterogeneous group of neurodegenerative diseases characterized by parkinsonian features—bradykinesia, rigidity, tremor, and gait impairment—occurring alongside additional ("plus") prominent neurological signs. These extra features typically include early postural instability with falls, vertical supranuclear gaze palsy, severe autonomic failure, cerebellar ataxia, early cognitive decline, or cortical…

Sweet’s Syndrome (acute febrile neutrophilic dermatosis)
Overview Sweet's syndrome, also known as acute febrile neutrophilic dermatosis , is an autoinflammatory skin disorder belonging to the group of non-infectious neutrophilic dermatoses . It is characterized by the sudden onset of high fever, leukocytosis with absolute neutrophilia, tender erythematous cutaneous papules, plaques, or nodules, and a dense dermal infiltrate of mature neutrophils on…

Hypermobility Syndromes
Overview Hypermobility Spectrum Disorder (HSD) describes symptomatic joint hypermobility with musculoskeletal (and sometimes systemic) consequences in people who do not meet the 2017 diagnostic criteria for hypermobile Ehlers–Danlos syndrome (hEDS) or another heritable connective-tissue disorder (HCTD). Prevalence of generalised joint hypermobility varies (≈2–35% depending on age/sex/ethnicity and cut-offs), with symptomatic states more common in females…

Systemic Sclerosis-Associated Interstitial Lung Disease
Overview Systemic sclerosis–associated interstitial lung disease (SSc-ILD) is one of the most common and severe internal organ manifestations of systemic sclerosis (SSc), occurring in up to 50–60% of patients on HRCT, with clinically significant disease in ~25–30%. It is a major cause of SSc-related mortality. The most frequent histopathological pattern is nonspecific interstitial pneumonia (NSIP),…

Gallstone Disease
This section looks at gallstone disease in general. For info on cholecystitis specifically click here . Overview Gallstones, also called cholelithiasis, are solid deposits formed from components of bile, most commonly cholesterol or bilirubin. They usually develop within the gallbladder but may migrate into the biliary ducts. Gallstones range from very small particles to large stones…

Good places to begin
Explanations learners return to.
Cancer – Introduction II
Continue exploring the fundamentals of cancer by examining how it grows, invades surrounding tissues, and spreads through metastasis. This video also discusses the role of the immune system, angiogenesis, and factors that influence cancer progression and treatment strategies.
Chemistry Revision IV – Electron Configuration
Understand the basics of electron configuration, including how electrons are arranged in shells, subshells, and orbitals. This video simplifies key rules like the Aufbau principle, Hund’s rule, and the Pauli exclusion principle to support your chemistry learning.
Viruses overview – structure, classification and bacteriophage replication
Explore the structure and classification of viruses, including key components like capsids, envelopes, and genetic material. This video also explains bacteriophage replication cycles, highlighting the lytic and lysogenic pathways in viral reproduction.
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…
