The word "dementia" is an umbrella term used to describe a set of symptoms, including impairment in memory, reasoning, judgment, language and other thinking skills. Dementia usually begins gradually, worsens over time and impairs a person's abilities in work, social interactions and relationships.
Forgetfulness can be a normal part of aging. As people get older, changes occur in all parts of the body, including the brain. As a result, some people may notice that it takes longer to learn new things, they don't remember information as well as they did, or they lose things like their glasses.
Dementia often occurs in older people. However, it's not related to normal aging. Alzheimer's disease is the most common form of dementia. Dementia makes it hard for people to remember, learn, and communicate. It may cause changes in mood and personality, such as depression.
The primary difference between the two is that mild forgetfulness does not significantly impact a person's life, while dementia can have permanent, debilitating effects.
You have trouble following a conversation. You find it hard to make decisions, finish a task or follow instructions. You start to have trouble finding your way around places you know well. You begin to have poor judgment.
Almost 40% of us will experience some form of memory loss after we turn 65 years old. But even if we experience memory loss, chances are still unlikely that we have dementia.
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.
Administration: The examiner reads a list of 5 words at a rate of one per second, giving the following instructions: “This is a memory test. I am going to read a list of words that you will have to remember now and later on. Listen carefully. When I am through, tell me as many words as you can remember.
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.
If you notice that the signs of forgetfulness in your aged parents indicate dementia, then consult a psychiatrist or neurologist to evaluate the situation. Forgetfulness can also be caused due to diabetes, hypertension, cholesterol, depression, anxiety, vitamin B deficiency and hypothyroidism.
The average life expectancy figures for the most common types of dementia are as follows: 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.
Keep in mind that even if your husband is experiencing some memory problems, it doesn't necessarily mean he has dementia. Many memory problems are brought on by other factors like stress, depression, thyroid disease, side effects of medications, sleep disorders, vitamin deficiencies and other medical conditions.
If you're frequently forgetting things that you always remembered before, that can be a red flag for mental deterioration or the onset of dementia. In general, if you are worried enough to ask yourself this question, you should speak to your doctor.
Vitamin B12 deficiency is linked to impaired cognition and memory along with a sensation of tingling and numbness, an outcome of poor myelination. Elevated methylmalonic acid and serum homocysteine levels are markers of Vitamin B12 deficiency.
Stage 2: Basic Forgetfulness
Very early stages of Alzheimer's can look like normal-aged forgetfulness. Your loved one might have memory lapses, including forgetting people's names or where they left their keys, but they can still drive, work and be social. However, these memory lapses become more frequent.
There is no one test to determine if someone has dementia. Doctors diagnose Alzheimer's and other types of dementia based on a careful medical history, a physical examination, laboratory tests, and the characteristic changes in thinking, day-to-day function and behavior associated with each type.
MCI means that the cognitive declines do not affect the person's ability to carry out everyday tasks (e.g., shopping, cooking, driving), while dementia indicates those cognitive difficulties are impacting the person's ability to complete everyday tasks.
Mini-Mental Status Examination (MMSE)
This test is usually conducted by your doctor or specialist in their office and takes around 5 minutes to complete. The MMSE is the most common test for the screening of dementia. It assesses skills such as reading, writing, orientation and short-term memory.
“Cognitive decline may begin after midlife, but most often occurs at higher ages (70 or higher).” (Aartsen, et al., 2002) “… relatively little decline in performance occurs until people are about 50 years old.” (Albert & Heaton, 1988).
Women can expect to live 4.2 years with mild impairment and 3.2 with dementia, men 3.5 and 1.8 years. A critical finding is that for the most advantaged groups (i.e., White and/or higher educated), cognitive impairment is both delayed and compressed toward the very end of life.
