Quick Summary
What is dementia progression?
Dementia progression refers to the way cognitive and functional abilities decline over time as the disease advances. It matters because understanding the typical pattern lets families anticipate changes, arrange support early, and make choices that respect the persons dignity.
Typical length of each stage
On average, the early stage lasts about 2 years, the middle stage 24 years, and the late stage 13 years, though many factorsage, overall health, type of dementiacan speed up or slow down this timeline. provides a detailed breakdown that many clinicians reference.
7Stage model vs. classic 3stage model
Most people learn dementia in three broad phases (mild, moderate, severe), but a more granular 7stage view can help you spot subtle shifts. Below is a sidebyside comparison.
| Model | Stage1 | Stage2 | Stage3 | Stage4 | Stage5 | Stage6 | Stage7 | Avg. Duration |
|---|---|---|---|---|---|---|---|---|
| 3stage | Early (Mild) | Middle (Moderate) | Late (Severe) | 510yrs | ||||
| 7stage | No impairment | VeryMild | Mild | Moderate | ModeratelySevere | Severe | Endoflife | 612yrs |
Seven Stages
Stage1: No Impairment (Preclinical)
What youll notice
Subtle wordfinding hiccups, occasional misplacements, but nothing that interferes with daily life.
Whos at risk?
People over 80 already face a higher chance of moving into the next stage, especially if they have a family history of dementia. cites age80 as a key turning point for life expectancy after a diagnosis.
Expert tip
Early cognitive screening (like the MoCA test) can catch tiny changes before they snowball. Neurologists often recommend an annual checkup once you cross 75.
Stage2: VeryMild (Early)
Signs
Forgetting recent conversations, misplacing items more often, and mild difficulty following complex instructions.
Sundowning?
Sundowningheightened confusion or agitation in the eveningusually hasn't shown up yet. It tends to appear later.
Stage3: Mild (EarlyMiddle)
Signs
Difficulty with multitasking, occasional mood swings, and the first hints of anger as the person senses loss of independence.
What stage is anger?
Anger often emerges in this stage (stage34) when the brains frustration pathways become overactive.
Realworld story

Stage4: Moderate (Middle)
Signs
Frequent memory gaps, getting lost in familiar places, early sundowning episodes, and the need for help with basic chores.
Longevity note
On average, people spend 24 years in this middle stage, according to a study published in .
Stage5: Moderately Severe
Signs
Assistance needed for dressing, bathing, and budgeting. Anger can spike as awareness of decline rises.
Safety checklist
Install grab bars in the bathroom
Use medication dispensers
Remove loose rugs that cause falls
Stage6: Severe (Late)
Signs
Limited speech, loss of mobility, pronounced sundowning, and incontinence. Even simple conversations become challenging.
Caregiver burden
Its common to feel exhausted. Short breaks, support groups, and respitecare services are lifesavers. Exondys 51 assistance programs are one example of how specialty support resources can reduce billing and insurance stress for families managing complex care needs.
Stage7: EndofLife (Very Severe)
Signs
Unable to recognize family, bedridden, swallowing difficulties, and a high risk of infections.
Palliative care
Ask your doctor about hospice, painmanagement plans, and advanced directives. Having these conversations early eases the emotional load later.
