Dementia affects individuals in different ways, causing both common and unique symptoms and experiences. There are seven clinical stages, also known as the Global Deterioration Scale (GDS). Understanding the stages of dementia helps patients, caregivers, and loved ones prepare for and deal with the disease and its progression.
Dementia symptoms worsen over time, although the rate that the disease progresses varies. Read on for an overview of the seven stages of dementia to help you better understand what to expect.
Stage 1: No Cognitive Decline
Symptoms are not noticeable at this early stage. Individuals function normally, and lapses in memory or cognitive ability are within the range of typical age-related changes. Regular medical check-ups may not reveal any signs of dementia.
Stage 2: Very Mild Cognitive Decline
This stage is characterized by minor memory lapses that are mistaken for normal aging. Individuals may forget familiar words or where they put certain objects or household items. These lapses do not impact the person’s ability to work or live independently and has very little impact on quality of life. At this stage, dementia is not usually detectable by healthcare professionals.
Stage 3: Mild Cognitive Decline
This stage, known as Mild Cognitive Impairment (MCI), involves more noticeable memory and cognitive issues. Individuals may have difficulty paying attention, finding the right words, remembering names, or planning and organizing tasks. Money management and scheduling becomes more difficult. While friends, family, or co-workers may start to notice these changes, they do not yet meet the criteria for dementia and quality of life is only slightly impacted.
Stage 4: Moderate Cognitive Decline
Cognitive decline becomes more apparent at this stage, also known as early-stage dementia. Symptoms include:
- Memory loss regarding anything from recent events to personal history.
- Forgetfulness of familiar words and names.
- Issues with daily tasks like driving, laundry, or shopping.
- Difficulty performing complex tasks, such as managing finances or planning a dinner for guests.
- Diminished problem-solving skills.
- Becoming moody or withdrawn, especially in socially or mentally challenging situations.
A dementia diagnosis is more definite at this stage, as cognitive decline becomes more evident during medical visits.
Stage 5: Moderately Severe Cognitive Decline
During this middle stage of dementia, individuals begin to need help with day-to-day activities. Symptoms may include:
- Repeating questions and stories.
- Gaps in memory and confusion about dates, time, and place.
- Forgetting address and/or phone number.
- Requiring help with eating or using the toilet.
- Incontinence/bladder control issues.
- Personality changes and mood swings.
Assistance becomes necessary, but the person may still maintain some level of independence. This may be a good time to contract senior in home care services to help support and care for the individual.
Stage 6: Severe Cognitive Decline
This stage marks a severe decline in cognitive abilities, with individuals requiring assistance with everyday activities. Symptoms include:
- Loss of awareness of recent experiences and surroundings.
- Strong personality changes and mood swings.
- Difficulty remembering the names of close family members
- Difficulty with hygiene and getting dressed.
- Inability to use the toilet or get dressed without help.
- Getting lost or wandering off.
- Issues sleeping at night and an inclination to sleep during the day.
- Lack of awareness of events and experiences.
- Changes in eating habits.
- Major changes in personality and behavior, including suspiciousness, paranoia and delusions.
Communication becomes more challenging during this stage, making professional care necessary to ensure the patient’s safety and well-being. At this stage, many consider moving their loved ones into assisted living facilities.
Stage 7: Very Severe Cognitive Decline
Individuals lose the ability to respond to their environment, to speak, and ultimately, to control movement during the final stage of dementia. Symptoms include:
- Loss or ability to speak, eat or swallow.
- Need for assistance with most daily activities, including eating, using the bathroom, and getting dressed.
- Inability to walk or sit without help.
- Loss of language skills.
- Loss of bladder and bowel control.
- Loss of muscle control.
- Inability to walk, resulting in confinement to a wheelchair or bed.
- Inability to recognize family members.
- Abnormal reflexes and rigid muscles.
- Consistent disorientation.
At this stage, the focus shifts to 24/7 palliative care; providing comfort and managing symptoms to maintain the highest quality of life possible.
Dementia is a progressive condition that affects each person differently. Understanding the stages can help caregivers and loved ones better anticipate and manage the challenges of this disease. Early diagnosis and intervention can improve the quality of life for those living with dementia, providing them with the support and care they need throughout its progression.
