What Are the Stages of Dementia?
The idea that you or a loved one may be suffering from dementia is frightening and unsettling. Understanding the condition is an important first step to knowing how to deal with dementia as it progresses.
Dementia vs. Alzheimer’s Disease
Dementia is often confused with Alzheimer’s disease when in reality, Alzheimer’s is actually one of the more than 400 causes of dementia. It is also the most well-known type of the condition.
Some of the different types of dementia include:
- Lewy Body dementia
- Pick’s disease
- Vascular dementia
- Parkinson’s disease dementia
- Creutzfeldt-Jakob disease
- Huntington’s disease
- Mixed dementia
Each cause and type affects brain function in a unique way. For example, Alzheimer’s disease creates plaques in the brain which leads to dementia. Parkinson’s disease (PD) creates nerve cell degeneration in the brain, and about 70% of PD patients develop dementia as a result. Additionally, clots, strokes, and other vascular conditions can decrease blood flow to the brain, resulting in vascular dementia.
Within the 7 stages of dementia, there are a constellation of symptoms that typically increase as the condition progresses. These symptoms include:
- Memory loss
- Loss of ability to think
- Loss of logical reasoning
- Inability to pay attention and focus
- Loss of other mental functions
Who Is at Risk for Dementia?
If you or a loved one is over 65, there is a 5% to 8% chance of having some form of dementia. By age 70 and every 5 years after, the percentage doubles. By the time older adults reach their 80s, as many as half of them will have some dementia symptoms.
The most common form of dementia is Alzheimer’s disease. That said, it’s no surprise that as many as 80% of dementia patients have Alzheimer’s disease and will require Alzheimer’s care as it progresses.
In the early stages of dementia, there are medications that can temporarily improve and/or slow down cognitive impairment symptoms, but studies have shown the effects only last 6 to 12 months.
While other medications may be used to help with depression, sleep difficulties, and agitation, the far more effective therapies over the long term are accomplished by managing symptoms, particularly agitation and other emotional concerns. Assistance with simplifying daily routines, along with interventions such as cognitive stimulation, physical activity, cognitive behavioral therapy, and reminiscence therapy may also help slow the stages of dementia.
In the later stages of dementia, the best option will likely be to move them to a caring, safe atmosphere like Legacy Pointe at UCF’s memory care community.

- Cannot speak or communicate
- Require help with most activities
- Loss of motor skills
- Cannot walk
