Brain Herniation
Overview Brain herniation is the pathological displacement of brain tissue across rigid intracranial structures, such as the falx cerebri or tentorium cerebelli, or through an opening such as the foramen magnum. It develops when a pressure gradient forces tissue from one intracranial compartment into another. 1 Herniation may compress the brainstem, cranial nerves and cerebral…

Shoulder Impingement Syndrome (Subacromial Pain Syndrome)
Overview Shoulder impingement syndrome, now more commonly referred to as subacromial pain syndrome (SAPS) , is one of the most frequent causes of shoulder pain. It accounts for ~40–65% of shoulder complaints in primary care and sports medicine settings. It occurs due to mechanical compression of the rotator cuff tendons (most commonly supraspinatus) and subacromial…

Multiple Sclerosis
"Each patient ought to feel somewhat the better after the physician's visit irrespective of the nature of the illness." -Warfield Theobald Longcope Overview Multiple sclerosis (MS) is defined as an inflammatory demyelinating disease characterised by the presence of episodic neurological dysfunction in at least 2 areas of the CNS (brain, spinal cord, and optic nerves)…

Carpal Tunnel Syndrome
Overview Carpal tunnel syndrome (CTS) is a compressive neuropathy of the median nerve as it passes beneath the transverse carpal ligament at the wrist. It is the most common peripheral nerve entrapment syndrome and typically causes nocturnal paraesthesia, numbness or pain involving the thumb, index finger, middle finger and radial half of the ring finger.…

Cardiac Sarcoidosis
Overview Cardiac sarcoidosis is an inflammatory heart disease caused by myocardial infiltration with non-necrotising granulomas. Inflammation may subsequently resolve, recur, or progress to permanent fibrosis. The disease is often patchy and may affect the conduction system, ventricular myocardium, papillary muscles, valves, pericardium, or coronary microcirculation. 1 Cardiac involvement may occur as part of multisystem sarcoidosis…

Chronic Upper Limb Ischaemia
Overview Chronic upper limb ischaemia is a form of peripheral arterial disease that results in a symptomatic reduced blood supply to the upper limb. The common symptoms are weakness, cramps, pain, and digital ischaemia/gangrene. Upper limb ischaemia occurs less frequently than lower limb ischaemia. Peripheral artery disease (PAD) is a chronic obstruction of arteries supplying…

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…

Good places to begin
Explanations learners return to.
Multiple Myeloma – signs and symptoms, pathophysiology, treatment
Dive into Multiple Myeloma as we explore its hallmark signs and symptoms, underlying pathophysiology, and current treatment options. This video provides a concise and clinically relevant guide for students and healthcare professionals.
Introduction to Myeloproliferative Disorders
Discover the basics of Myeloproliferative Disorders — their types, causes, symptoms, and diagnosis. A concise overview designed for medical students, healthcare professionals, and anyone interested in hematology.
Malaria – Plasmodium
Learn about malaria and the Plasmodium species responsible for infection, including their life cycle, transmission, and impact on red blood cells. This video explains the key stages in the human host and mosquito vector, along with clinical features of the disease.
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…
