Understanding Dementia
A Comprehensive Guide
An accessible overview of the major types of dementia — their causes, symptoms, and behavioral changes — to support patients, families, and caregivers.
What is Dementia?
Dementia is not a single disease — it is an umbrella term for a group of symptoms caused by disorders that affect the brain. These symptoms include memory loss, difficulty with thinking, problem-solving, language, and changes in mood and behavior.
Different types of dementia are associated with particular types of brain cell damage in particular regions of the brain, resulting in distinct patterns of symptoms. Understanding the type of dementia is essential for treatment, care planning, and family support.
There is currently no cure for most forms of dementia, but early diagnosis and appropriate care can significantly improve quality of life.
Alzheimer's Disease
The most common cause of dementia, caused by abnormal protein buildups (amyloid plaques and tau tangles) that progressively destroy brain cells. It develops slowly and worsens over time, typically beginning after age 65.
- ▸ Amyloid plaques build up between nerve cells
- ▸ Tau tangles form inside dying cells
- ▸ Brain cells lose connections and die
- ▸ Brain shrinks significantly over time
- ▸ Hippocampus (memory center) affected first
- ▸ Forgetting recent conversations and events
- ▸ Misplacing items frequently
- ▸ Difficulty finding words
- ▸ Confusion about dates, time, or place
- ▸ Trouble with planning and problem-solving
- ▸ Difficulty recognizing family members (late)
- ▸ Agitation and aggression
- ▸ Wandering and getting lost
- ▸ Sundowning (evening confusion)
- ▸ Depression and social withdrawal
- ▸ Paranoia and delusions
- ▸ Repetitive questioning and actions
Key Facts

Vascular Dementia
Caused by reduced or blocked blood flow to the brain — due to strokes, mini-strokes, or diseased blood vessels — starving brain cells of oxygen. Often develops suddenly after a stroke or in a stepwise pattern of decline.
- ▸ Strokes or mini-strokes (TIAs) damage brain tissue
- ▸ Diseased small blood vessels restrict flow
- ▸ Brain cells die from lack of oxygen
- ▸ Decline often stepwise — stable then sudden drop
- ▸ Cardiovascular risk factors are primary drivers
- ▸ Slowed thinking and poor concentration
- ▸ Difficulty planning and organizing
- ▸ Memory issues (less prominent than Alzheimer's)
- ▸ Shuffling gait and balance problems
- ▸ Urinary incontinence
- ▸ Confusion in unfamiliar environments
- ▸ Depression — often one of the earliest signs
- ▸ Emotional instability (sudden crying or laughing)
- ▸ Apathy and withdrawal
- ▸ Anxiety and fearfulness
- ▸ Personality changes — more passive or irritable
- ▸ Sleep disturbances and insomnia
Key Facts
How Our Team Can Help
Post-stroke care coordination
We mobilize quickly after stroke events to stabilize environment, routines, and safety protocols immediately.
Mobility and fall prevention
Trained caregivers support safe movement, assist with shuffling gait, and minimize fall hazards throughout the home.
Depression and emotional support
We recognize depression as a clinical symptom, not a mood, and engage your loved one with warmth, structure, and purposeful activity.
Cardiovascular health monitoring
Our team works alongside physicians to support blood pressure management and lifestyle factors that can slow further decline.
Adaptive care plans
As vascular dementia progresses in steps, our RN-reviewed plans adjust after each decline to meet your loved one's current reality.

Lewy Body Dementia
Caused by abnormal protein deposits (Lewy bodies) forming inside nerve cells in areas governing thinking and movement. One of the most complex and frequently misdiagnosed dementias, sharing features with both Alzheimer's and Parkinson's.
- ▸ Alpha-synuclein protein clumps form (Lewy bodies)
- ▸ Deposits spread through brain over time
- ▸ Affects regions for memory, thinking and movement
- ▸ Two forms: DLB and Parkinson's Disease Dementia
- ▸ Often misdiagnosed as Alzheimer's or Parkinson's
- ▸ Vivid, detailed visual hallucinations (early)
- ▸ Fluctuating alertness — clear one moment, confused the next
- ▸ Parkinson's-like movement symptoms
- ▸ REM Sleep Behavior Disorder (acting out dreams)
- ▸ Frequent falls and balance problems
- ▸ Fainting and dizziness (autonomic issues)
- ▸ Vivid hallucinations — people, children, animals
- ▸ Paranoia and delusions (Capgras syndrome)
- ▸ Severe depression affecting up to 50%
- ▸ Dramatic cognitive fluctuations within one day
- ▸ REM sleep disorder — physical dream acting
- ▸ Anxiety related to hallucinations
Key Facts
⚠️ Critical Safety Warning: Standard antipsychotic medications (e.g., haloperidol) can cause severe, life-threatening reactions in people with Lewy Body Dementia. All caregivers and medical professionals must be informed of this risk before any medication is prescribed.
How Our Team Can Help
Hallucination-informed response
We respond with calm and validation — never arguing or dismissing — reducing distress for your loved one in the moment.
Antipsychotic safety oversight
Our caregivers and RN team ensure all medical providers are informed of LBD's severe medication sensitivities before any prescription is made.
Cognitive fluctuation monitoring
We track and document daily fluctuations, adjusting activities and expectations to match your loved one's capacity in each moment.
REM sleep disorder support
We create safe sleep environments and nighttime routines that minimize injury risk during dream-enacting episodes.
Specialist care coordination
We actively communicate with neurologists to ensure care plans reflect LBD-specific needs at every stage of the disease.

Frontotemporal Dementia (FTD)
Caused by progressive damage to the frontal and temporal lobes — the areas governing personality, behavior, language, and decision-making. Unlike other dementias, memory is often preserved early while personality and behavior change dramatically.
- ▸ Behavioral Variant FTD (bvFTD) — most common; affects personality
- ▸ Primary Progressive Aphasia — affects language
- ▸ Semantic variant — loss of word meaning
- ▸ Nonfluent variant — difficulty producing speech
- ▸ FTD-MND — overlaps with ALS (Lou Gehrig's)
- ▸ Dramatic personality changes (earliest sign)
- ▸ Poor judgment and impulsive decisions
- ▸ Loss of empathy and emotional warmth
- ▸ Socially inappropriate behavior
- ▸ Language difficulties (depending on variant)
- ▸ Compulsive eating — craving sweets and carbs
- ▸ Disinhibition — rude, inappropriate actions without awareness
- ▸ Profound loss of empathy — appearing cold or indifferent
- ▸ Compulsive, ritualistic behaviors
- ▸ Impulsive financial or personal decisions
- ▸ Little to no insight into own behavior changes
- ▸ Profound apathy — often mistaken for depression
Key Facts
How Our Team Can Help
Behavioral boundary support
We use calm, structured approaches to manage disinhibition and impulsive behaviors — without shame, confrontation, or restraint.
Family education and reframing
We help families understand that behavioral changes are symptoms of brain damage — reducing guilt, confusion, and relationship strain.
Structured daily routines
FTD responds well to predictability. We build tight daily routines that reduce impulsive decision-making and compulsive behavior patterns.
Language and communication support
For language-variant FTD, our caregivers adapt — using gesture, visuals, and simplified speech to stay meaningfully connected.
Younger-onset care planning
We navigate the unique challenges of caring for someone in their 40s or 50s — including work, finances, children, and shifting family roles.
Navigating a new FTD diagnosis?
Many families come to us in shock — and we meet them there. Let's build a plan together at whatever pace feels right.

Mixed Dementia
A condition where two or more types of dementia occur simultaneously — most commonly Alzheimer's combined with vascular dementia. Far more common than previously recognized, especially in older adults, and often only confirmed at autopsy.
- ▸ Alzheimer's + Vascular — most frequent
- ▸ Alzheimer's + Lewy Body — second most common
- ▸ Alzheimer's + Vascular + Lewy Body — triple pathology
- ▸ Vascular + Lewy Body — less common but recognized
- ▸ Often only confirmed through brain autopsy
- ▸ Broader, more complex symptom profile
- ▸ Memory loss and forgetfulness
- ▸ Slowed thinking and concentration problems
- ▸ Language difficulties
- ▸ Walking and balance issues
- ▸ Faster overall progression than single-type dementia
- ▸ More varied and unpredictable than single-type
- ▸ Agitation, depression, and anxiety
- ▸ Hallucinations (if Lewy body involved)
- ▸ Paranoia and delusions
- ▸ Wandering and sundowning
- ▸ Emotional instability and mood swings
Key Facts
How Our Team Can Help
Multi-condition care coordination
We map symptoms to each pathology present and build a unified care response — not a generic plan that misses what matters most.
Hallucination and agitation management
When Lewy body is part of the mix, our hallucination protocols and medication safety oversight apply without exception.
Wandering and sundowning response
When Alzheimer's pathology is active, our behavioral protocols address evening confusion and unsafe movement directly.
Caregiver relief and family support
We actively relieve family caregiver burden through structured visits, respite options, and consistent transparent communication.
Integrated RN wellness reporting
Monthly reports track changes across all active conditions — giving families a complete, objective picture of their loved one's health.
Caring for someone with more than one form of dementia?
Mixed dementia needs a team that understands all of it — not just one piece. Let's build that plan together.

Parkinson's Disease Dementia
Develops in people who already have Parkinson's disease when the same Lewy body deposits that cause motor symptoms spread to areas governing thinking and memory — typically 10–15 years after the initial Parkinson's diagnosis.
- ▸ Resting tremor in hands or limbs
- ▸ Slowness of movement (bradykinesia)
- ▸ Muscle rigidity and stiffness
- ▸ Freezing of gait — suddenly unable to move
- ▸ Masked face — reduced facial expression
- ▸ Soft, slurred speech and swallowing difficulties
- ▸ Slowed thinking and processing speed
- ▸ Difficulty with attention and concentration
- ▸ Visuospatial problems — misjudging distances
- ▸ Memory loss worsening over time
- ▸ Language and word-finding difficulties
- ▸ Cognitive fluctuations — clear then confused
- ▸ Vivid visual hallucinations (common and early)
- ▸ Depression affecting 50–70% of patients
- ▸ REM Sleep Behavior Disorder — acting out dreams
- ▸ Apathy — distinct from and coexisting with depression
- ▸ Paranoia and delusions (Capgras syndrome)
- ▸ Impulse control disorders from dopamine medications
Key Facts
⚠️ Critical Safety Warning: Like Lewy Body Dementia, people with Parkinson's Disease Dementia have severe sensitivity to traditional antipsychotic medications. Only quetiapine or clozapine may be considered, under close specialist supervision. All care providers must be informed.
How Our Team Can Help
Motor and mobility assistance
Our caregivers assist with movement, support freezing-of-gait episodes, and help your loved one navigate the home safely and with dignity.
Swallowing and speech support
We work alongside speech therapists and adapt mealtimes to reduce choking risk as swallowing difficulties develop and progress.
Medication safety oversight
Our team ensures all care providers know traditional antipsychotics are contraindicated — only quetiapine or clozapine under specialist supervision.
Depression and apathy care
We distinguish between depression and apathy — treating each appropriately with targeted engagement, activity, and emotional attunement.
Multidisciplinary team coordination
We actively coordinate with neurologists, movement disorder specialists, and speech and physical therapists to align all care.

Korsakoff Syndrome
A chronic brain disorder caused by severe thiamine (Vitamin B1) deficiency, most commonly from long-term heavy alcohol use. Produces profound and often permanent memory impairment. Uniquely, it is largely preventable with adequate thiamine supplementation.
- ▸ Wernicke's Encephalopathy (Acute): sudden confusion, abnormal eye movements, severe loss of coordination — a medical emergency
- ▸ Korsakoff Syndrome (Chronic): develops if Wernicke's untreated — 80–90% of untreated cases progress to this stage
- ▸ Together called Wernicke-Korsakoff Syndrome
- ▸ Anterograde amnesia — cannot form new memories
- ▸ Retrograde amnesia — loses past memories
- ▸ Confabulation — unconsciously fabricates false memories
- ▸ Preserved procedural memory (can ride a bike)
- ▸ Disorientation to time and place
- ▸ Relatively preserved immediate memory (seconds only)
- ▸ Confabulation — fabricating plausible but false memories without awareness
- ▸ Profound apathy and emotional flatness
- ▸ No insight into own memory impairment
- ▸ Passivity and docility — unusual cooperativeness
- ▸ Highly suggestible — easily led by questions
- ▸ Depression and anxiety in those with insight
Key Facts
⚠️ Critical Safety Warning: If Wernicke's Encephalopathy is suspected, high-dose intravenous thiamine must be administered immediately — before any glucose or carbohydrates. Giving glucose first can precipitate or dramatically worsen the condition. Do not delay treatment pending confirmation of diagnosis.
How Our Team Can Help
Confabulation-informed communication
We never correct or shame — we redirect with warmth, understanding confabulation is the brain's unconscious response to memory gaps.
Nutritional health support
Thiamine and nutritional wellbeing remain critical. We support healthy meals and monitor nutritional status as part of daily care.
Procedural memory-based activities
Preserved procedural memory means your loved one may still cook, play music, or ride a bike. We build around what remains, not what's lost.
Addiction-sensitive family care
We hold space for complex family dynamics without judgment — and help families rebuild connection on their own terms.
Dignity-first daily routines
Structure, predictability, and respect form the backbone of every day — reducing anxiety for a loved one who cannot form new memories.
