Wordology, Anosognosia

My brother, whatshisname sent this to me, although he swears he never read it. Anosognosia is a deficit of self-awareness, the inability of a person to be aware of their own disability or illness.

French Professor Bruno Dubois Director of the Institute of Memory and Alzheimer's Disease at La Pitié-Salpêtrière - Paris Hospitals says, "If anyone is aware of his memory problems, he does not have Alzheimer's. . .The more we complain about memory loss, the less likely we are to suffer from memory sickness."

Many people over sixty forget the names of family or friends, forget where they put things, forget why they walked into another room, or misplace keys and other items. It is usually temporary forgetfulness. Half or more of these people have some symptoms that are due to age rather than disease or Anosognosia.

We are learning that forgetfulness is not a disease, but rather a frustrating characteristic due to age. The important thing is, those who are conscious of being forgetful have no serious problem of memory, but those who suffer from a memory illness, Alzheimer's, or Anosognosia, are not aware of what is happening.

Alzheimer's vs. Dementia

There are about fifty million people living with dementia worldwide, according to the World Health Organization. Dementia and Alzheimer’s disease are often used interchangeably, but there are differences.
Alzheimer’s disease is a specific type of dementia and is the most common. Alzheimer’s is a brain disease marked by deposits of beta-amyloid plaques and proteins called tau that damage cells in brain regions that control functions like thinking, memory, and reasoning. With Alzheimer’s, you may forget new information or find that you need to ask family members to remember important facts you should be able to remember for yourself. It is not where you cannot remember the name of your barber and then it comes to you later.

Dementia is an umbrella term for symptoms like impaired memory and thinking that interferes with daily living. According to the Alzheimer’s Association, in order for a person to be diagnosed with dementia, two of the following must be “significantly impaired”: memory, communication and language, the ability to focus and pay attention, reasoning and judgment, and visual perception. A medical illness, metabolic issue (like a nutritional or thyroid problem), vascular disease (like a stroke), or infectious diseases can affect brain cells, causing dementia.
There are no FDA-approved therapies for dementia, but there are four medications that target Alzheimer’s. These drugs do not stall disease progression or cure the disease, but they can help control symptoms.


All Alzheimer's is dementia, but not all dementia is Alzheimer's. 

Eight Tips for a Healthier Brain

Studies have shown that regular aerobic exercise boosts daily intellectual performance and significantly lowers risk for dementia. Other studies have suggested that regular exercise can reduce that risk by up to 38 percent. More studies have shown that maintaining a healthy weight with a low ratio of belly fat can significantly lower our risk for a memory disorder, even beginning in middle age.

Managing chronic conditions, such as hypertension or diabetes can significantly reduce risk for stroke and dementia. Also, taking care of medical issues such as hearing or vision loss can make a tremendous difference in our ability to learn new information.

Emotional distress and anxiety can also affect everyday abilities and may even increase risk for memory impairment. Get a good night’s sleep, avoid risky behaviors, and do not ignore emotional upsets. A leading study on successful aging found that folks who aged well were more emotionally resilient than others.

Playing games against the clock activities force us to pay attention, work fast, and think nimbly. Research shows that training in these skills can help us stay more effective at them, regardless of age.

Research shows that staying intellectually engaged can significantly lower risk for memory impairment by as much as 63 percent. Intellectual engagement supports emotional well-being and better brain health. Look for ways to change your routine, such as taking a craft class, brushing your teeth with your non-dominant hand, or taking a new route to work or the store.

Staying social has been shown to potentially cut your risk for memory impairment in half. Social situations offer a challenge to keep up our end of the conversation and helps us stay focused, and think fast. Find ways to get out with friends, and ways to engage through community or other resources.

Working or volunteering can improve daily intellectual performance. You get a good brain workout on the job, which offers you the chance to engage both mentally and socially. Continuing to work or volunteer provides a sense of purpose, which researchers found may protect us from memory impairment.

If you want to remember better, believe that you can. Self-perception can impact performance. If you are convinced your memory is poor, it probably will be. Studies have shown that memory self-belief impacts how well we do on memory tests. Practice the power of positive thinking.

Alzheimer's and Dementia

Both Alzheimer’s and dementia are associated with a loss of memory, but there is a difference. Alzheimer’s refers to a physical change in the makeup of the brain, which causes dementia as one of its major symptoms. Dementia can be a symptom of other diseases as well.

Dementia is one of the major symptoms of and the final stage in the progression of Alzheimer’s (an age-related disease that is characterized by symptoms other than just memory loss, as well as by a physical change in brain tissue). When a person suffers from the symptom of dementia, it means that they are afflicted by memory loss and an overall decline in their ability to process information. In order to be diagnosed with dementia, a person must demonstrate impaired abilities in two of the following areas: memory, ability to focus, reasoning and judgment, visual perception, and communication.

Dementia is diagnosed when the symptoms get so bad they interfere with a person’s ability to function on a daily basis. Forgetfulness and memory loss is a normal part of aging, but dementia is defined as severe instances of those.

Common causes for dementia can include vitamin deficiencies or problems in other parts of the body, such as the thyroid. Some medications can cause dementia as one of their side effects, and the excessive use of alcohol can also lead to dementia. It generally starts out mild and progresses slowly over years. In some cases it can be treated and reversed.

Alzheimer’s can be one of the causes of dementia. It describes a physical condition in which there is a change in the tissue of the brain, including the formation of structures called amyloid plaques and neurofibrillary tangles. They are blockages in the brain that prevent the transmission of signals. The loss of signals between the brain’s neurons results in dementia, among other symptoms.

In addition to dementia, those who suffer from Alzheimer’s often show other signs of cognitive difficulty. This can include a loss of depth and spatial perception, abnormal sleep patterns, and an inability to visualize and understand abstract concepts, such as numbers. There is often a change in personality, as well, and a person can become angry, restless, or paranoid. Those afflicted with the disease often have trouble following directions or fulfilling requests, and may also lack the motivation to do so. This lack of motivation can extend to all areas of life, from getting up in the morning to interacting with other people.

Alzheimer’s also worsens over time, and three distinct stages have been identified. The first is a stage where there are no symptoms, but the disease it starting to develop in the brain. In the second, symptoms begin to manifest themselves and the person suffers from mild, but not complete cognitive impairment. In the third stage, symptoms progress to full-blown dementia.

Currently, there are no cures or preventative methods for Alzheimer’s, and those who are diagnosed with it will eventually need around-the-clock, complete care. What triggers the development of Alzheimer’s is unknown, although many doctors point to an all-around healthy lifestyle as the best way to keep brain function at healthy levels, regardless of age.
Bottom line, Alzheimer's and other diseases can cause dementia, while dementia can be a symptom of Alzheimer's.

Nitpicking, Bigwigs, and Perukes

By 1580, syphilis had become the worst epidemic to strike Europe since the Black Death. Without antibiotics, victims developed open sores, nasty rashes, blindness, dementia, and patchy hair loss.

Powdered wigs, called perukes saved the day. Victims hid their baldness, as well as the bloody sores that scored their faces, with wigs made of horse, goat, or human hair and coated with powder scented with lavender or orange, to hide the odor. Wigs were not necessarily stylish, just a shameful necessity.

When Louis XIV was only 17 his hair began thinning. He hired 48 wig makers to save his image. Five years later, the King of England, Louis’ cousin, Charles II, did the same thing when his hair started to gray. Other aristocrats immediately copied the two kings. They sported ostentatious wigs, and the style trickled down to the upper-middle class.

The cost of wigs increased, and perukes became a scheme for flaunting wealth. An everyday wig cost about 25 shillings, a week’s pay for a commoner. The bill for large, elaborate perukes could cost as much as 800 shillings. The word 'bigwig' was coined to describe snobs who could afford big, flowing wigs.

At the same time, head lice were everywhere and nitpicking was a painful and time-consuming chore. Wigs curbed the problem. Lice stopped infesting people’s hair, which had to be shaved for the wig to fit, and moved to the wigs. Delousing a wig was much easier than delousing a head of hair. A wig-maker would simply boil the wig to remove the nits.
