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. Physiology of…

Long-Term Complications of Diabetes (Overview)
Overview Long-term complications of diabetes are chronic injuries affecting blood vessels, nerves and organs in both type 1 and type 2 diabetes. The principal groups are microvascular disease (retinopathy, kidney disease and neuropathy) and macrovascular disease (coronary, cerebrovascular and peripheral arterial disease). They may develop silently before causing visual loss, kidney failure, pain, disability or…

Developmental Hip Dysplasia
Overview Developmental Dyplasia of the hip (DDH) is previously known as congenital dislocation of the hip (however name changed as some of the hip problems develop after birth). Spectrum of condition related to development of the hip in infants and young children. Includes abnormal development of the acetabulum and proximal femur + mechanical instability of the hip joint. Usually involves…

Viral Encephalitis
Overview Viral encephalitis is an acute, life-threatening inflammatory condition of the brain parenchyma caused by direct viral invasion or secondary immune-mediated mechanisms. It represents a neurological emergency associated with high rates of mortality and long-term neurodevelopmental or cognitive sequelae if treatment is delayed. Infectious encephalitis is distinct from aseptic viral meningitis; while meningitis is confined…

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.

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.
Femoroacetabular Impingement Syndrome
Overview Femoroacetabular impingement syndrome (FAIS) is a motion-related clinical disorder of the hip in which symptoms and clinical signs occur in association with characteristic femoral and/or acetabular morphology. The accepted diagnostic concept is a triad of symptoms, clinical signs and imaging findings ; bone morphology alone does not establish the syndrome. Patients commonly present with…
