Asthma (Adults)
Clinical features of asthma such as dyspnoea, chest tightness and wheezing can mimic other respiratory conditions. It is important to take a careful history and examination and ideally demonstrate reversible airflow obstruction. Other clinical features of asthma arise during periods of bronchoconstriction (ie. exercise, smoking, stress, cold air). Exacerbation of asthma confounds the breathing difficulty, cough and wheeze in patients.

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…

Long-Term Complications of Diabetes (Overview)
Overview Classification Microvascular Complications Retinopathy Nephropathy Neuropathy Macrovascular Complications Coronary heart disease Cerebrovascular disease Diabetic foot Diabetic Retinopathy Overview Diabetes is the most common cause of blindness in the working population. Blindness is preventable. Annual retinal screening is advised for patients at risk. Pre-symptomatic screening enables laser photocoagulation to be used, aimed to stop production of…

Carotid Sinus Hypersensitivity
Overview Carotid sinus hypersensitivity is an exaggerated autonomic response to stimulation of the carotid sinus. The resulting reflex may cause marked bradycardia, transient asystole, vasodilatation, hypotension, or a combination of these effects. This can reduce cerebral perfusion and produce presyncope or syncope. 1 Carotid sinus hypersensitivity is a physiological finding demonstrated during carotid sinus massage.…

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)…

Febrile Seizure
Overview Seizures are a common occurrence in children. 8% will have at least one seizure by 15 years of age. A seizure is the result of an abnormal paroxysmal discharge by cerebral neurons. Many underlying conditions and neurological challenges may provoke seizures, and in over 50% of children seizures are isolated events associated with either a fever…

X-linked Agammaglobulinaemia (XLA / Bruton’s Disease)
Overview X-linked agammaglobulinaemia (XLA) is a rare primary immunodeficiency caused by mutations in the Bruton’s tyrosine kinase (BTK) gene , leading to failure of B-cell maturation. It results in profound hypogammaglobulinaemia and susceptibility to recurrent bacterial infections, particularly with encapsulated organisms. It usually presents after 6 months of age (once maternal IgG wanes). Prevalence is…

Explanations learners return to.
Headache – Overview (types, signs and symptoms, treatment)
Explore the different types of headaches including tension, migraine, and cluster, along with their characteristic signs and symptoms. This video also covers key treatment options and clinical clues for effective headache management.
Overview of Fluid and Electrolyte Physiology (Fluid Compartment)
This video offers a clear overview of fluid and electrolyte physiology, focusing on the body's major fluid compartments and their roles in homeostasis. Learn how water and electrolytes are distributed, regulated, and clinically significant in health and disease.
Immunology – Interleukin 1 (IL1) physiology and IL1 antagonist pharmacology
Explore the role of Interleukin-1 (IL-1) in immune responses, including its effects on inflammation, fever, and cytokine signaling. This video also covers the pharmacology of IL-1 antagonists, detailing their mechanisms of action and clinical applications in inflammatory diseases.
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…
