Dementia vs. Alzheimer's Disease: What is the Difference? Dementia is a general term for a decline in mental ability severe enough to interfere with daily life, while Alzheimer's is a specific disease. Alzheimer's is the most common cause of dementia.
While dementia is a general term, Alzheimer's disease is a specific brain disease. It is marked by symptoms of dementia that gradually get worse over time. Alzheimer's disease first affects the part of the brain associated with learning, so early symptoms often include changes in memory, thinking and reasoning skills.
Early signs and symptoms of Alzheimer's dementia
Memory impairment, such as difficulty remembering events. Difficulty concentrating, planning or problem-solving. Problems finishing daily tasks at home or at work, such as writing or using eating utensils. Confusion with location or passage of time.
Overall, know that Alzheimer's disease is a specific disease, while dementia is a general term for a group of similar diseases, of which Alzheimer's is one. In other words, every case of Alzheimer's disease is an example of dementia, but not every type of dementia is Alzheimer's.
Alzheimer's disease – around eight to 10 years. Life expectancy is less if the person is diagnosed in their 80s or 90s. A few people with Alzheimer's live for longer, sometimes for 15 or even 20 years. Vascular dementia – around five years.
On average, a person with Alzheimer's lives four to eight years after diagnosis, but can live as long as 20 years, depending on other factors.
Many people affected by dementia are concerned that they may inherit or pass on dementia. The majority of dementia is not inherited by children and grandchildren. In rarer types of dementia there may be a strong genetic link, but these are only a tiny proportion of overall cases of dementia.
Introduction: The five-word test (5WT) is a serial verbal memory test with semantic cuing. It is proposed to rapidly evaluate memory of aging people and has previously shown its sensitivity and its specificity in identifying patients with AD.
Don't correct, contradict, blame or insist. Reminders are rarely kind. They tell a person how disabled they are – over and over again. People living with dementia say and do normal things for someone with memory impairment.
The Mini-Cog test.
A third test, known as the Mini-Cog, takes 2 to 4 minutes to administer and involves asking patients to recall three words after drawing a picture of a clock. If a patient shows no difficulties recalling the words, it is inferred that he or she does not have dementia.
The five-minute cognitive test (FCT) was designed to capture deficits in five domains of cognitive abilities, including episodic memory, language fluency, time orientation, visuospatial function, and executive function.
Patient assessment tools:
The GPCOG is a screening tool for cognitive impairment designed for use in primary care and is available in multiple languages. Mini-Cog - The Mini-Cog is a 3-minute test consisting of a recall test for memory and a scored clock-drawing test.
The Montreal Cognitive Assessment (MoCA) is a tool that helps healthcare professionals detect mild cognitive impairment and Alzheimer's disease in people. A 2021 study found that it is a better measure of cognitive function than the MMSE. It consists of 30 questions that take 10–12 minutes to accomplish.
Scientists don't yet fully understand what causes Alzheimer's disease in most people. The causes probably include a combination of age-related changes in the brain, along with genetic, environmental, and lifestyle factors.
The SAGE test is a 12-question exam that measures cognitive functioning and may help a physician determine whether Alzheimer's is present.
The main sign of mild cognitive impairment is a slight decline in mental abilities. Examples include: Memory loss: You may forget recent events or repeat the same questions and stories. You may occasionally forget the names of friends and family members or forget appointments or planned events.
The Self-Administered Gerocognitive Exam, known as SAGE, is a brief, pen-and-paper cognitive assessment tool designed to detect the early signs of cognitive, memory, or thinking impairments. The test evaluates your thinking abilities. This can help your doctors understand how well your brain is functioning.
We all inherit a copy of some form of APOE from each parent. Those who inherit one copy of APOE-e4 from their mother or father have an increased risk of developing Alzheimer's. Those who inherit two copies from their mother and father have an even higher risk, but not a certainty.
While there is no conclusive evidence that we can prevent the development of dementia, there is a general acknowledgement that there are some areas where poor lifestyle choices may increase the risk of developing dementia (that is, a poor diet, smoking, drinking excessive amounts of alcohol, lack of exercise, and not ...
Although there is no effective treatment or proven prevention for Alzheimer's and related dementias, in general, leading a healthy lifestyle may help address risk factors that have been associated with these diseases.
Stage 6: Severe Mental Decline/Moderately Severe Dementia Quality of life: Severe impact. Your loved one will not remember much or any of the past and may not recognize you and other family and friends.
One of the most common causes of death for people with dementia is pneumonia caused by an infection. A person in the later stages of dementia may have symptoms that suggest that they are close to death, but can sometimes live with these symptoms for many months.
