Diagnosis information
Core diagnostic criteria, specifiers, differential considerations, and documentation support in one open, scan-friendly view.
All criteria are shown. No expand controls or hidden sections.
Core criterion A
Criteria met for major or mild NCD (substantial or modest cognitive decline in ≥1 domain)
Core criterion B
Insidious onset and gradual progression in ≥1 cognitive domain (most often episodic memory early)
Core criterion C
Probable AD: genetic mutation or ≥2 declining domains + no mixed aetiology; Possible AD: no genetic evidence or insufficient domains or mixed aetiology present
Core criterion D
Disturbance not better explained by cerebrovascular disease, another NCD, medical condition, or substances
Consistent with [Alzheimer's Disease] [specifier(s)]. There is insidious onset with gradual, progressive decline in one or more cognitive domains, with episodic memory impairment (particularly anterograde learning) typically the earliest and most prominent feature. Additional domains affected may include complex attention, executive functioning, language (word-finding, naming), perceptual-motor abilities, and social cognition. The pattern is consistent with Alzheimer's disease neuropathology, characterised by relentless progression without prolonged plateaus or stepwise changes. Symptoms cause clinically significant impairment in independence for instrumental or basic activities of daily living. The disturbance does not occur exclusively during delirium and is not better explained by another neurological disorder, medical condition, substance use, or primary psychiatric disorder. Reversible causes of cognitive impairment must be actively excluded.
