A study (2009) found that dementia prevalence (total number of cases) increased with age: 10 percent of those age 65 to 80, 13.5 percent at 80 to 84 years; 30.8 percent at 85 to 89 years; 39.5 percent at 90 to 94 years; and 52.8 percent among those older than 94. Prevalence was 25.8 percent among women and 17.1 percent among men.
So as we age, there is a greater chance of getting Dementia, but until we hit our 90’s the odds against getting Dementia are on our side. However, as we age we become more concerned with memory loss because memory loss disrupts our daily life may be a symptom of Alzheimer's or another dementia.
Alzheimer's is a brain disease that causes a slow decline in memory, thinking and reasoning skills. There are 10 warning signs and symptoms. Every individual may experience one or more of these signs in a different degree. If you notice any of them, please see a doctor. In the following from the Alzheimer’s Association, there are clear warning signs but there are also typical age-related changes. The warning sign information shows the severity of the problem, the typical age-related changes are much less severe.
1. MEMORY LOSS THAT DISRUPTS DAILY LIFE
One of the most common signs of Alzheimer's is memory loss, especially forgetting recently learned information. Others include forgetting important dates or events; asking for the same information over and over; increasingly needing to rely on memory aids (e.g., reminder notes or electronic devices) or family members for things they used to handle on their own.
What's a typical age-related change?
Sometimes forgetting names or appointments, but remembering them later.
2. CHALLENGES IN PLANNING OR SOLVING PROBLEMS
Some people may experience changes in their ability to develop and follow a plan or work with numbers. They may have trouble following a familiar recipe or keeping track of monthly bills. They may have difficulty concentrating and take much longer to do things than they did before.
What's a typical age-related change?
Making occasional errors when balancing a check book.
People with Alzheimer's often find it hard to complete daily tasks. Sometimes, people may have trouble driving to a familiar location, managing a budget at work or remembering the rules of a favorite game.
What's a typical age-related change?
Occasionally needing help to use the settings on a microwave or to record a television show.
4. CONFUSION WITH TIME OR PLACE
People with Alzheimer's can lose track of dates, seasons and the passage of time. They may have trouble understanding something if it is not happening immediately. Sometimes they may forget where they are or how they got there.
What's a typical age-related change?
Getting confused about the day of the week but figuring it out later.
5. TROUBLE UNDERSTANDING VISUAL IMAGES AND SPATIAL RELATIONSHIPS
For some people, having vision problems is a sign of Alzheimer's. They may have difficulty reading, judging distance and determining color or contrast, which may cause problems with driving.
6. NEW PROBLEMS WITH WORDS IN SPEAKING OR WRITING
People with Alzheimer's may have trouble following or joining a conversation. They may stop in the middle of a conversation and have no idea how to continue or they may repeat themselves. They may struggle with vocabulary, have problems finding the right word or call things by the wrong name (e.g., calling a "watch" a "hand-clock").
What's a typical age-related change?
Sometimes having trouble finding the right word.
7. MISPLACING THINGS AND LOSING THE ABILITY TO RETRACE STEPS
A person with Alzheimer's disease may put things in unusual places. They may lose things and be unable to go back over their steps to find them again. Sometimes, they may accuse others of stealing. This may occur more frequently over time.
What's a typical age-related change?
Misplacing things from time to time and retracing steps to find them.
8. DECREASED OR POOR JUDGMENT
People with Alzheimer's may experience changes in judgment or decision-making. For example, they may use poor judgment when dealing with money, giving large amounts to telemarketers. They may pay less attention to grooming or keeping themselves clean.
What's a typical age-related change?
Making a bad decision once in a while.
9. WITHDRAWAL FROM WORK OR SOCIAL ACTIVITIES
A person with Alzheimer's may start to remove themselves from hobbies, social activities, work projects or sports. They may have trouble keeping up with a favorite sports team or remembering how to complete a favorite hobby. They may also avoid being social because of the changes they have experienced.
10.CHANGES IN MOOD AND PERSONALITY
The mood and personalities of people with Alzheimer's can change. They can become confused, suspicious, depressed, fearful or anxious. They may be easily upset at home, at work, with friends or in places where they are out of their comfort zone.
What's a typical age-related change?
Developing very specific ways of doing things and becoming irritable when a routine is disrupted.
