Understanding Dementia: Brain Science and Caregiving

Identify Alzheimer's, vascular, Lewy body, and frontotemporal dementias and their distinct brain regions, symptoms, and progression. Understand how accurate diagnosis, biomarkers, and care planning guide treatment and caregiving.

Discover how doctors diagnose dementia early using history, memory tests, interviews, brain scans, and lab work to guide treatment, plan care, and distinguish reversible causes.

Explore how genetics and modifiable risk factors shape dementia risk, examine ApoE, Presenilin 1 and 2, and APP roles, and learn how diet and exercise influence brain and heart health.

Explore how amyloid plaques and tau tangles damage brain cells, starting in the hippocampus and spreading to the cortex to cause inflammation, acetylcholine loss, brain atrophy, and memory decline.

Explore how Lewy body dementia, vascular, and frontotemporal dementias differ from Alzheimer's by detailing brain region targets, pathology, and hallmark symptoms like hallucinations, stepwise decline, and language changes.

Explore the mild, moderate, and severe stages of dementia, detailing memory loss, daily task challenges, diagnosis and planning, and care strategies for families.

Explore why dementia-related behaviors arise as communication signals, not symptoms. Apply the abc model to identify triggers, responses, and consequences, and respond with calm environments and simple choices.

Learn dementia-aware communication that accommodates language changes in Broca's and Wernicke's areas using short words, simple phrases, calm pace, and nonverbal cues.

Develop daily caregiving skills for people with dementia by using predictable routines, simple choices, calm communication, and dignity-preserving support during dressing, bathing, eating, and toileting.

Discover how dementia affects eating and drinking, signs of dehydration and malnutrition, and how caregivers promote nourishment and dignity through calm meals, familiar foods, and hydration strategies.

Learn how cholinesterase inhibitors raise acetylcholine to aid memory in early Alzheimer's and how memantine supports attention in later stages, plus cautious use of mood meds and monoclonal antibodies.

Explore non-pharmacological dementia care strategies—music, movement, sensory activities, routines, and therapeutic communication—to reduce anxiety, boost mood, and personalize care through familiar cues and deep emotional memories.

Tailor cognitive, physical, and sensory activities for individuals with dementia to fit their interests, abilities, and stage, boosting identity, mood, and connection through familiar tasks that aren’t too difficult.

Learn to manage safety and wandering in dementia by understanding sundowning, reducing hazards, and using visual cues, grab bars, door chimes, and GPS trackers to balance safety and independence.

Navigate legal and financial planning after dementia diagnosis by establishing durable power of attorney for finances and health care, advanced directives, and guardianship options to protect rights and reduce stress.

Explore how dementia caregiving is a 24/7 responsibility, highlighting stress, burnout, ambiguous loss, and self-care strategies to maintain emotional and physical well-being through support.

Provide comfort-focused end-of-life care for dementia, prioritizing pain relief, gentle presence, and peaceful environments. Highlight hospice and palliative options, support families, and cherish meaningful moments through touch, music, and love.
