Recognizing and managing symptoms of Alzheimer’s disease

What Are The Signs And Symptoms of Alzheimer’s Disease And Related Dementias

Alzheimer’s Disease and related dementias are devastating neurodegenerative illnesses that significantly affect cognitive abilities in the elderly. As the disease progresses, individuals with Alzheimer’s may experience a range of symptoms including memory problems and difficulty recalling recent events. They may begin to struggle with completing familiar tasks and routine activities. Additionally, changes in the brain can lead to impaired judgment and decision-making abilities.

Individuals with Alzheimer’s may also experience personality changes such as increased anxiety and depression, mood swings, and delusions. In some cases, symptoms may escalate to aggression and paranoia. Family members and caregivers often report noticing changes in everyday behavior, such as changes in eating habits and lack of interest in usually enjoyable activities. Early detection and intervention can help slow the progression of the disease and improve the overall quality of life for those affected.

The 10 warning signs of dementia

1. Memory loss:

This is one of the most common early signs of dementia. People may forget important dates or events, frequently ask for the same information or rely heavily on memory aids.

2. Difficulty with planning and problem-solving:

Individuals with dementia may have trouble following a recipe, managing finances, or completing familiar tasks that require planning and organization.

3. Confusion with time and place:

They may lose track of dates, seasons, or time. They might forget where they are or how they got there.

4. Challenges with language: 

People with dementia may struggle to find the right words, have difficulty following conversations, or repeat themselves frequently.

5. Poor judgment: 

They may exhibit poor judgment or decision-making abilities, such as giving away large sums of money to telemarketers or neglecting personal hygiene.

6. Misplacing items: 

Dementia can lead to putting things in unusual places and being unable to retrace steps to find them.

7. Changes in mood or personality: 

Dementia can lead to putting things in unusual places and being unable to retrace steps to find them.

8. Withdrawal from social activities: 

Dementia can cause a person to lose interest in socializing, hobbies, or previously enjoyed activities. They may also struggle with maintaining conversations.

9. Decreased or poor judgment: 

Individuals may decline decisions, such as dressing inappropriately for the weather or engaging in risky behaviors.

10. Difficulty with visual perception: 

They may have trouble judging distances, recognizing objects, or interpreting colors and contrasts.

Can you recognize the warning signs of Alzheimer’s disease?

 Alzheimer’s disease usually affects those who are above the age of 65 and can be a frightening prospect, with no known cure. However, it is important to be aware of the early-stage warning signs to identify them as soon as possible. The disease is known to bring cognitive decline, with the individual experiencing memory loss, difficulty in problem-solving and decision-making, and confusion.

It is not uncommon for the affected individual to struggle with familiar tasks like cooking, paying bills, or dressing up. The person might also experience changes in their mood and behavior, such as social withdrawal or depression. Recognizing these warning signs is crucial as early intervention can help slow the disease progression and improve the quality of life for both the caregiver and the patient. Seeking professional advice and regular check-ups can also aid in the early diagnosis and management of the disease. 

Alzheimer’s Disease and Related Forms of Dementia

Alzheimer’s disease and related forms of dementia refer to a group of neurological disorders that result in a decline in cognitive function, memory loss, and personality changes. In the early stage, symptoms such as forgetfulness and difficulty in completing daily tasks are common. The disease is the most common cause of dementia amongst older adults, and its prevalence is increasing as the global population ages. The National Institute on Aging works to understand the disease’s causes, improve diagnosis, and find potential interventions and treatments through extensive research.

Here is some information about Alzheimer’s disease and a few related forms of dementia

1. Alzheimer’s Disease (AD)

Alzheimer’s disease is the most common form of dementia, accounting for 60-80% of all cases. It primarily affects memory, thinking, and behavior. The exact cause of Alzheimer’s is not yet fully understood, but it is believed to involve a combination of genetic, environmental, and lifestyle factors. The hallmark signs include memory loss, difficulty with language and problem-solving, confusion, disorientation, and changes in mood and personality. As the disease progresses, individuals may require assistance with daily activities.

2. Vascular Dementia

Vascular dementia is the second most common form of dementia. It results from reduced blood flow to the brain, often due to strokes or other conditions that affect blood vessels. Symptoms can vary depending on the areas of the brain affected, but they may include difficulties with planning, organizing, problem-solving, and a decline in thinking skills. Vascular dementia can sometimes coexist with Alzheimer’s disease, leading to a mixed form of dementia.

3. Lewy Body Dementia (LBD)

LBD is characterized by abnormal protein deposits called Lewy bodies in the brain. It shares some symptoms with Alzheimer’s and Parkinson’s disease, including cognitive decline, memory problems, visual hallucinations, fluctuations in attention and alertness, and motor symptoms such as stiffness and tremors. People with LBD may also experience fluctuations in their cognitive abilities throughout the day.

4. Frontotemporal Dementia (FTD)

Frontotemporal dementia is a group of disorders that primarily affect the frontal and temporal lobes of the brain, causing changes in behavior, personality, and language skills. It typically manifests in individuals under the age of 65 and is characterized by significant alterations in social behavior, emotional blunting, language difficulties, and poor judgment. Memory loss is not usually a prominent early feature of FTD.

5. Parkinson’s Disease Dementia (PDD)

Parkinson’s disease is a movement disorder, but in some cases, it can progress to involve cognitive decline and dementia. PDD shares some similarities with Lewy body dementia, including motor symptoms like tremors and rigidity. Cognitive symptoms include memory impairment, executive dysfunction, and difficulties with attention and visuospatial abilities.

The 7 Stages of Alzheimer’s Disease

Alzheimer’s disease is a progressive brain disorder that affects memory, thinking, and behavior. It typically progresses in seven stages, ranging from the earliest stage of mild cognitive impairment to the advanced stage of severe dementia. During early stages, individuals may have difficulty with short-term memory and concentration, while late-stage Alzheimer’s may cause an inability to communicate and carry out even basic daily activities. Treatment options are available to manage symptoms, but there is currently no cure for Alzheimer’s disease.

The commonly referenced seven stages are:

Stage 1:

No Impairment In the early stage of Alzheimer’s, there are typically no noticeable cognitive impairments. The individual functions independently and does not exhibit any memory problems or other symptoms.

Stage 2:

Very Mild Cognitive Decline At this stage, individuals may start to experience subtle changes in cognitive function. They may have occasional memory lapses, such as forgetting familiar words or misplacing objects. These changes may not be immediately apparent to others or may be attributed to normal age-related forgetfulness.

Stage 3:

Mild Cognitive Decline In stage 3, mild cognitive impairment becomes more noticeable. Memory lapses become more frequent, and individuals may have difficulty recalling names, organizing thoughts, or finding the right words. They may also experience challenges with concentration, planning, and problem-solving. These changes may start to affect daily activities and work performance.

Stage 4:

Moderate Cognitive Decline (Mild or Early-Stage Alzheimer’s) In this stage, clear cognitive impairments are evident. Memory loss and confusion become more pronounced, and individuals may struggle with tasks that require significant cognitive abilities, such as managing finances or planning. They may have difficulty remembering recent events or personal details and may show increased irritability or withdrawal from social activities.

Stage 5:

Moderately Severe Cognitive Decline (Moderate or Mid-Stage Alzheimer’s) At this point, individuals require more assistance with daily activities. They may have difficulty dressing appropriately, may not recall the current time or date, and could struggle with basic tasks like bathing or preparing meals. Memory deficits extend to personal history, and they may experience confusion about their surroundings or significant life events. However, they can still recognize familiar faces and retain some awareness of their own name.

Stage 6:

Severe Cognitive Decline (Moderately Severe or Mid-Stage Alzheimer’s) In stage 6, individuals require substantial support and supervision. Memory continues to deteriorate, and they may have difficulty recognizing close family members or even their own reflections. There may be significant behavioral changes, including aggression, agitation, and wandering. Assistance is needed with all activities of daily living, and the individual may require help with toileting and personal hygiene.

Stage 7:

Very Severe Cognitive Decline (Severe or Late-Stage Alzheimer’s) In the final stage of Alzheimer’s disease, individuals lose the ability to communicate verbally, walk independently, and control movement. They require around-the-clock care and assistance with all aspects of daily living. The physical decline becomes more prominent, and they may become bedridden. Individuals in this stage are highly vulnerable to infections and other complications.

Dementia-related pain: What caregivers need to know

Dementia-related pain can be difficult to identify in people with the condition. Caregivers should be aware of nonverbal cues such as facial expressions, moaning, and changes in behavior. They should also communicate regularly with healthcare providers to ensure that the person with dementia is receiving appropriate pain management.

Symptoms of dementia

 The symptoms of dementia can vary depending on the type of dementia and the stage of the disease. Memory loss is the most common symptom of dementia, but other symptoms may include difficulty with problem-solving, communication, and completing familiar tasks. Changes in mood, behavior, and personality are also common symptoms.

In the later stages of dementia, individuals may experience difficulty with mobility and require full-time care. It is important to speak with a healthcare professional if you or a loved one is experiencing any of these symptoms. 

What Is Mild Cognitive Impairment?

Mild cognitive impairment (MCI) refers to a decline in cognitive abilities that exceed those of age-related changes, but are not severe enough to interfere with everyday activities. Individuals with MCI may experience memory problems, difficulty with language, poor judgment, decreased attention span, and problems with visual perception.

Although MCI is a risk factor for developing dementia, not all individuals with MCI will progress to dementia. It is important for individuals experiencing cognitive decline to seek medical attention and have a thorough evaluation to determine the cause and appropriate treatment. 

Memory loss that disrupts daily life

 Memory loss can be a common experience for many people, especially as they age. However, when it begins to disrupt their daily lives, it may be a sign of something more serious. This type of memory loss is known as dementia, and it can vary in severity from mild forgetfulness to complete loss of cognitive abilities. It can affect not only memory but also language, decision-making, and other mental functions. Dementia is a progressive disease, which means symptoms will worsen over time. It is important to seek medical attention if you or a loved one are experiencing memory loss that disrupts daily life, to determine if it is indeed dementia or another condition that can be treated.


Alzheimer’s disease and related dementias are debilitating conditions that significantly impact cognitive abilities. Recognizing the signs and symptoms of these diseases, such as memory loss, difficulty with problem-solving and language, changes in mood and behavior, and challenges with daily tasks is crucial for early detection and intervention. Caregivers play a vital role in understanding and addressing the needs of individuals with dementia, including identifying signs of pain and providing appropriate support. Seeking professional advice, regular check-ups, and staying informed can help in managing the progression of the disease and improving the quality of life for those affected.
