Cognitive decline represents a clinical continuum spanning healthy cognitive aging, Mild Cognitive Impairment (MCI), and Major Neurocognitive Disorder (Dementia). Mild Cognitive Impairment (MCI) involves objective cognitive decline in one or more domains (memory, executive, language, visuospatial) that is greater than expected for age, yet independence in activities of daily living is preserved. In contrast, Dementia involves progressive, irreversible cognitive erosion severe enough to compromise independent living. Grounded in behavioral neurology and neuropathology, the Mild Cognitive Impairment and Dementia Psychoeducation Module delivers 24 structured video lessons covering Alzheimer’s amyloid/tau cascades, Vascular Dementia, Lewy Body Dementia, Frontotemporal Lobar Degeneration (FTD), and person-centered caregiver support.

Differential Profiles: Alzheimer’s, Vascular, Lewy Body, and FTD
- Alzheimer’s Disease (AD): Insidious onset with early episodic anterograde amnesia (hippocampal neurofibrillary tangles and beta-amyloid plaques), followed by aphasia, apraxia, and agnosia.
- Vascular Dementia (VaD): Stepwise cognitive deterioration associated with cerebrovascular infarcts, characterized by prominent early executive slowing and gait abnormalities.
- Dementia with Lewy Bodies (DLB): Alpha-synuclein inclusions producing the triad of fluctuating cognition, vivid visual hallucinations, and spontaneous parkinsonism. Antipsychotics carry extreme neuroleptic sensitivity risks.
- Frontotemporal Dementia (FTD): Early onset (ages 45-65) marked by profound personality changes, social disinhibition, apathy, or progressive primary language deficits.
Tom Kitwood’s Person-Centered Dementia Care
Kitwood emphasized that dementia disability is the interactive product of neurological impairment and the “malignant social psychology” of the environment (infantilization, invalidation, outpacing). Preserving personhood through sensory engagement, validation therapy, and circadian stabilization enhances quality of life across all stages.
