In addition, individuals with Alzheimer's disease and other dementias frequently become unable to appreciate other people's feelings or needs as sensitively as they once did. As a result, they can seem “selfish” or “self-centered”, and uncaring about other peoples' needs or feelings.
They may rely on confabulation or “lies” to fill the gaps in their memory, and they may demonstrate childlike behaviors such as emotional outbursts and downright noncompliance with instructions and requests. To caregivers, this behavior may come across as intentionally manipulative, but this is rarely the case.
Dementia can affect someone's inhibitions. This means they may stop following the usual social rules about how to behave. Disinhibited behaviours can seem tactless, rude or offensive. These behaviours can place enormous strain on families and carers.
Dementia can affect a person's personality and habits, which may lead to changes in behaviour. For example, they may no longer be able to do things they enjoy or follow their interests without help, or they may experience symptoms of depression.
The person may be having delusions (strongly believing things that aren't true), or hallucinations (seeing things that aren't there). This can be confusing and frightening, so the person with dementia may respond in an aggressive way. The person may be sexually frustrated and become agitated as a result.
Some of the more common triggers for dementia like a change in environment, having personal space invaded, or being emotionally overwhelmed may be easier to handle if you mentally practice your response before you react.
In the combined data sets, the scientists found more amyloid and tau deposits in participants who scored higher in neuroticism and lower in conscientiousness.
It could be that your elderly parent has developed narcissism in their old age, this can be due to a variety of reasons, including trauma, or depression. It could also be that they are exhibiting some narcissistic traits because of dementia.
Behavioral disturbances in dementia are often globally described as “agitation” including verbal and physical aggression, wandering, and hoarding. These symptoms create patient and caregiver distress, and lead to nursing home placement.
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 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.
People who experience a decline in their condition may become more concerned or worried about their health – leading to repetitive negative thinking. Or, amyloid or tau could have accumulated in the brain, disrupted its circuitry, making it more difficult to disengage from negative thoughts.
Alzheimer's disease progressively destroys brain cells over time, so during the early stages of dementia, many do recognize something is wrong, but not everyone is aware. They may know they are supposed to recognize you, but they can't.
Dr. Petersen says, “Many times, when people develop Alzheimer's disease, their personality traits sort of become exaggerated. So if they're a genuinely nice person and have been quite affable throughout most of their life, that continues into the disease process.”
Dementia behavior: Aggression. Verbal threats and physical aggression can be among the more serious of the dementia behaviors. These verbal or physical outbursts may occur seemingly out of nowhere. They tend to happen in the latter stage of dementia, when patients can't communicate their needs.
A narcissistic senior may display erratic behavior or make inappropriate comments. To someone who doesn't know the individual, this could look like cognitive decline. However, those who are familiar with their behavior may attribute it to their narcissism.
The development of narcissistic traits is in many cases, a consequence of neglect or excessive appraisal. In some cases, this pathological self-structure arises under childhood conditions of inadequate warmth, approval and excessive idealization, where parents do not see or accept the child as they are.
Histrionic personality disorder (HPD) and narcissistic personality disorder (NPD) are part of the same cluster, which includes disorders characterized by heightened emotions and dramatic or unpredictable behaviors.
increased agitation. aggression (shouting or screaming, verbal abuse, and sometimes physical abuse) delusions (unusual beliefs not based on reality) hallucinations (hearing or seeing things that do not exist)
Higher neuroticism and lower conscientiousness are risk factors for Alzheimer's disease and related dementias, but the underlying neuropathological correlates remain unclear.
While everyone loses some neurons as they age, people with dementia experience far greater loss. The signs and symptoms can vary depending on the type and may include: Experiencing memory loss, poor judgment, and confusion. Difficulty speaking, understanding and expressing thoughts, or reading and writing.
other long-term health problems – dementia tends to progress more quickly if the person is living with other conditions, such as heart disease, diabetes or high blood pressure, particularly if these are not well-managed.
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.
The most well-known form of dementia, Alzheimer's disease, is just one specific type of dementia, and tends to have the slowest progression of all types.
