Stages of Dementia For Elderly Individuals

Understanding dementia progression is critical for making informed medical and personal decisions about memory care. Recognizing early warning signs can guarantee a diagnosis, so you can analyze common symptoms of moderate and late-stage dementia and prepare for the future. Knowing what to watch out for as you or your family member advances through the dementia phases can help determine when it is time to reassess care needs.

7 Stages Of Dementia

The most common types of dementia, including Alzheimer's disease, are progressive, which means that cognitive deterioration worsens over time. Dementia is classified as mild, moderate, or severe, as well as an early, middle, or late stage.

Health care providers frequently utilize a more comprehensive method to assess elderly patients' seven stages of dementia. The Global Deterioration Scale (GDS), also known as the Reisberg Scale, was created in 1982 by Dr. Barry Reisberg, a geriatric psychiatrist, and professor.

Dementia Stages 1-3: No Formal Diagnosis

Typically, people in the first three stages of dementia do not exhibit sufficient symptoms to be diagnosed — while cognitive impairment may exist, stages 1-3 on the GDS are not typically recognized as the early stages of dementia.

Dementia Stage 1

While it may seem strange, the lowest stage is normal mental functioning or the absence of cognitive impairment.

Dementia Stage 2

As per the Fisher Center for Alzheimer's Research, at least half of the population 65 and older report experiencing some little age-related forgetfulness. Such minor impairment may go unnoticed by caregivers or medical providers, and it is not indicative of the early stages of dementia.

Dementia Stage 3

When memory and cognitive difficulties become more obvious to caregivers and family members, a person is said to have mild cognitive impairment (MCI). It normally has little effect on day-to-day functioning.

How fast does dementia progress in the elderly? According to the National Institute on Aging, eight out of ten people with MCI will develop Alzheimer's disease within seven years. Due to the fact that MCI can precede more severe stages of dementia, it is critical to detect the indicators of this stage and seek medical treatment.

Dementia Stage 4

At this time, a person's mental dysfunction is obvious and evident. While it is considered mild or early-stage dementia, the fourth of the seven stages is medically referred to as "moderate cognitive decline."

Doctors and caregivers will almost certainly note an escalation of stage 3 dementia symptoms, including difficulties with language, problem-solving, and travel.

Dementia Stage 5

This stage indicates the commencement of what many professionals refer to as the "mid-stage" of dementia's seven stages.

At this point, an individual may be unable to do routine activities of daily living (ADLs), such as dressing or bathing, without the support of a caregiver. They recall basic details about themselves — like their name and their children's names — but may forget the names of their grandchildren, their long-term address, or where they attended high school.

Dementia Stage 6

Stage 6 indicates the need for caregiver assistance with routine daily activities such as dressing, eating, grooming, and other self-care. Seniors with late-stage dementia may struggle with sleep regulation, social interaction, and proper behavior in public settings.

Dementia Stage 7

Individuals with severe Alzheimer's disease or late-stage dementia are essentially incapable of caring for themselves. In general, all verbal capacity is gone, and ambulation and movement are significantly hindered. By the end of the seven stages of dementia, physical processes such as chewing, swallowing, and breathing may have deteriorated.

When a senior should seek memory care will vary according to their dementia symptoms, health status, and living situation, among other factors.
