 The Stages of Dementia

The symptoms of dementia appear gradually, and in stages. Knowing more about each stage can help you to identify the symptoms earlier and begin treatment sooner.

Stage 1 – Mild

Stage 1 usually lasts between two to four years, and is known as the pre-dementia stage. People in this stage will still be able to function in a fairly normal way, although short-term memory loss can become apparent. For example,  the person may forget important appointments, misplace or lose objects, or forget everyday words. They may have trouble recalling recent events or conversations and may repeatedly ask the same question.

It is not uncommon for someone in this stage to display apathy or depression and they may need prompting or encouragement to carry out normal day-to-day activities.

Stage Two – Moderate

In stage two, a person may begin to struggle with declining memory. Which may start to display changes in behavior such as aggression and erratic mood swings.

Memory loss can be affected to the extent that the person no longer recognizes family members or caregivers, and can become suspicious of others. Speech can become confused and the person may also feel lost in familiar places, often unable to find their way home. Behavior can also be inappropriate or uninhibited such as publicly undressing.

Mobility and balance can also be affected. Physical coordination can become impaired, so daily activities such as dressing, washing, and eating may require assistance. The person will need frequent help and reminding about many aspects of daily life. So adding structure to the day can help to reduce feelings of agitation and anxiety. This stage will usually last between two to 10 years.

Stage Three – Severe

In the final stage of dementia, the person will lose their memory, ability to process information and to communicate effectively. The loss of these cognitive functions can lead to extreme confusion, often mixing up past and present, severe mood swings, delusions, and even hallucinations.

Physically, they may have trouble with bodily functions such as swallowing and are often incontinent. At this stage, which can last between one to three years, the person will need full-time care and primary caregivers may need to consider other options such as a trained caregiver to assist at home. If in-home care for a family member becomes too difficult then it is reassuring to know live-in care facilities such as Longhouse can offer much-needed, dementia-focused care and support for your loved one.

Being aware of the likely stages of dementia can help you to manage the onset of symptoms and to plan care options for the future.
