As we age our brains begin to change naturally. We start to have problems remembering certain things. It can take longer for us to remember names or events from the past. While some cognitive changes are healthy aging some are signs of dementia. Understanding the signs and stages of dementia, rather than normal aging, can help you plan and prepare for the future.
Older adults are more likely to become distracted, forget appointments, or find it difficult to multi-task. This is completely normal among older adults and not signs of memory impairment. These are normal signs of an aging brain.
As we age, the hippocampus, a region of the brain responsible for memory, begins to deteriorate which contributes to age-related memory loss. Decreased hormone production and blood flow to the brain, as well as certain medications, can also lead to changes in memory. Memory problems that begin to regularly interfere with normal everyday life can be an indicator of Mild Cognitive Impairment (MCI) or dementia.

Dementia is a general term that refers to a decline in cognitive function that significantly impacts your ability to perform activities of daily living. Alzheimer’s disease is a type of dementia. Both dementia and Alzheimer’s disease impact memory, language, attention, reasoning, and judgment. Because Alzheimer’s disease has a specific pathology, the signs and stages referred to in this article are related to general dementia, although they are frequently present in someone living with Alzheimer’s disease as well.
Signs and stages of dementia include both cognitive changes and psychological changes. Signs of dementia include:
Signs and stages of dementia can vary depending on what changes are occurring in the brain. There are many types of dementia and it’s important to see a doctor and get a precise diagnosis so you can understand treatment options and plan and prepare for the future.

In general terms, dementia can be classified into early, middle, or late-stage, which can also be referred to as mild, moderate, and severe dementia stages. The Alzheimer’s Association and some health care providers use the 7 Stages of Alzheimer’s disease as a framework for understanding the progression of Alzheimer’s related dementia.
In the early or mild stage of dementia, people are still able to function somewhat independently. They might forget things or have trouble focusing but it does not prevent them from managing life. As the dementia progresses, disruption to their lives will begin to occur daily resulting in a need for assistance with some tasks. In this stage, increased confusion, poor judgment, changes in personality and behavior may occur. They may begin to withdraw from family and friends, and although they are aware of their memory issues, they will often deny it. One common symptom in the middle stage of dementia is sundowning – increased confusion, agitation, and irritability that occurs when daylight fades. Sundowning can disrupt sleep patterns, leading to being awake at night and sleeping more during the day.
In the severe or late stage of dementia, individuals will experience loss of physical abilities. They may lose their ability to communicate, lose control of their bladder or bowel functions, even their ability to walk, sit up or eat. They may begin hallucinating and may not recognize their spouse or children. They will not understand time or seasons or be able to dress appropriately for the weather. In this late stage of dementia, wandering or elopement becomes a risk. A person may wander around the house attempting to complete a task yet not do anything. They may go out the front door for the mail, forget what they went outside for, then not remember where they live.
People living with dementia will progress through the stages at different times and experience a variety of symptoms. One day they may acknowledge their need for help and the next day they might refuse it. To plan and prepare for the future, it is important to understand the signs and stages of dementia, however, it is equally important to get a dementia diagnosis from a doctor. Starting with a family doctor is a good first step, but seeing a neurologist, someone who specializes in disorders of the brain, is important as well. Once you have a diagnosis, supporting your loved one starts with planning for the future.
Having a conversation with your loved one about who will make healthcare decisions and deal with finances as the disease progresses is a good second step. This is a difficult conversation, and you may have to have it several times as the dementia progresses. You will also want to discuss how your loved one would prefer their care needs be met. Do they want a family member to provide care? Would they prefer hiring a home health care agency? Would they prefer living in a memory support community? Again, this is an ongoing conversation but one that you will want to have sooner rather than later.
