Harvard HMS Dementia Course 2025 (consolidated curricular source)

Harvard Medical School. "Dementia: A Comprehensive Update." Continuing Medical Education course, 2025. Faculty included Bradford Dickerson, Jason Karlawish, Helen Kales, Mary Mittelman, Bruce Miller, James Galvin, Marsel Mesulam, Clifford Ballard, Seth Price, John Shaughnessy, Sandra Weintraub, Kirk Daffner, and others. Three of those lectures are cited separately as their own source notes — Dickerson, Karlawish, Kales, and Mittelman — because their content is load-bearing for specific wiki claims.

Consolidated scope

This source captures the shared curricular picture of the 2025 HMS Dementia CME — the framework statements that appear across lectures and are not attached to a single speaker. It is cited when a wiki claim reflects the course as a body of clinical teaching rather than a single argument.

Key points used in wiki

Dementia is not one disease

  • The course treats dementia as a family of syndromes, each with distinct cognitive, behavioral, and functional profiles. Alzheimer's disease is the most common subtype, but care planning, risk, and prognosis depend on which syndrome is present.
  • Subtypes covered across the 2025 course include:
  • Alzheimer's disease (AD) — predominantly amnestic at onset, with variable early executive and language involvement.
  • Vascular cognitive impairment (VCI) — cognitive effects of cerebrovascular disease, often stepwise rather than smoothly progressive, and highly modifiable by cardiovascular risk control (HMS Vascular Cognitive Impairment lecture, 2025).
  • Dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD) — parkinsonian motor features, visual hallucinations, fluctuating cognition, REM sleep behavior disorder, and notable antipsychotic sensitivity (Galvin, The Parkinsonian Dementias, 2025).
  • Frontotemporal dementia (FTD) — behavioral variant (bvFTD) and primary progressive aphasia (PPA) variants, with early personality, language, or executive change rather than memory as the dominant presentation (Miller, FTD Harvard 2025; Mesulam, Harvard 2025 Mesulam).
  • Frontal-executive dementias more broadly — frontal-subcortical circuits and their cognitive signature (Daffner, 2025).
  • Each subtype implies different caregiver realities. FTD caregivers face personality and disinhibition change early; LBD caregivers face hallucinations and falls; VCI caregivers face sudden stepwise loss and the possibility of slowing progression through vascular risk management.

Diagnosis, disclosure, and care planning

  • Case-based teaching (Harvard Dementia Course Cases, 2025) emphasizes that a careful diagnostic workup — history, informant input, examination, neuropsychology, structural and sometimes molecular imaging — matters because different subtypes have different treatment and planning implications.
  • Some cognitive presentations are partially reversible or modifiable (e.g., depression, medications, thyroid, B12, NPH, sleep apnea, untreated vascular risk), and missing them shortcuts both patient outcome and caregiver planning.
  • Biomarker disclosure and diagnosis-as-narrative shape how patients and families plan ahead — see Karlawish, Mind Care, for the mind-care framing; see Weintraub (2025) for cognitive-status communication in practice.
  • Several lectures (Price 2025; Shaughnessy 2025; Ballard 2025; Kales 2025) emphasize that care planning is multidisciplinary and longitudinal: medical, psychiatric, functional, legal, financial, and social needs all shift as disease progresses, and no single clinician or discipline can carry the full care plan.
  • A dedicated legal lecture in the 2025 series (Dementia and the Law: Testamentary Capacity and Undue Influence) treats capacity as decision-specific and time-specific, not a single binary determination — which is why advance planning is more effective the earlier it begins.
  • End-of-life conversations in dementia are often delayed because decline is slow; the course flags this as a systemic problem in dementia care.

Why it matters for the wiki

  • Gives a single citable anchor for the claim that dementia is not one disease, and that caregiver realities differ meaningfully by subtype — load-bearing for conditions/dementia.md and for any future per-subtype page.
  • Provides academic grounding for existing wiki claims about diagnostic workup, reversible lookalikes, and early planning — without multiplying per-lecture source notes for material that is common across the course.
