Medical Terminology

517 terms across 31 categories — evidence-based, APA cited

Every term in this glossary includes APA 7th edition citations from peer-reviewed journals and official Australian guidelines. Our sources include: The Lancet, Journal of Alzheimer's Disease, International Journal of Geriatric Psychiatry, Dementia Australia evidence briefs, Australian Nursing and Midwifery Board standards, and clinical handbooks from the Wicking Dementia Research and Education Centre (University of Tasmania). This ensures the definitions you read are current, clinically accurate, and legislatively informed.

The DSM-5-TR (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, Text Revision — American Psychiatric Association, 2022) is the definitive clinical reference for diagnosing mental health conditions in Australia and internationally. It is the standard used by psychiatrists, psychologists, geriatricians, and GPs when diagnosing dementia-related conditions (classified as Major and Mild Neurocognitive Disorders), depression, delirium, anxiety disorders, and BPSD.

For professionals and students: Understanding DSM-5 diagnostic criteria helps you understand why a person has been given a particular diagnosis, what symptoms are expected, and how care should be tailored. It is not a tool for lay use — diagnosis requires a qualified clinician — but familiarity with its framework supports better clinical communication and more informed advocacy.

Educational resource. All definitions include APA citations. Each term links to the Merriam-Webster Medical Dictionary — a peer-reviewed professional medical reference. This glossary supports learning and does not replace clinical education or professional supervision.

The Human Brain — Visual Reference

The human brain is the most complex organ in the known universe — containing approximately 86 billion neurons (Azevedo et al., 2009) and an enormous number of synaptic connections, with published totals varying widely depending on the counting method (von Bartheld et al., 2016). Weighing approximately 1.4 kg, it controls every thought, memory, emotion, and bodily function.

Understanding the brain's anatomy is foundational to dementia care — each type of dementia targets different brain regions, causing different patterns of cognitive and behavioural change. The terms below cover the key structures, their functions, and their relevance to dementia and aged care practice.

Frontal — behaviour & planningTemporal — memory & languageParietal — spatial & touchOccipital — vision
