Alzheimer's is a type of dementia that typically causes problems with memory, thinking and behavior. Alzheimer's disease is the most common form of dementia.
Alzheimer's disease affects memory, thinking, concentration, and judgment; and, ultimately impedes a person’s ability to perform normal daily activities.
In order to be an effective Alzheimer's caregiver or to communicate with someone living with Alzheimer's disease, you must build a solid foundation of understanding.
Alzheimer's disease is the most common form of dementia.
Alzheimer's disease affects a person's memory, mood, and behavior.
Memory difficulties and behavior changes can be early signs of Alzheimer's disease.
1. Over time, a person with Alzheimer's disease has trouble thinking, remembering, speaking, learning, making judgments, and planning.
2. Persons suffering from Alzheimer's are often moody, restless, and sometimes mean.
3. Alzheimer's disease affects almost all aspects of brain functioning, including personality, and the ability to perform the most basic activities of daily functioning.
Alzheimer's disease is a an irreversible brain disorder with no known cure.
The cause of Alzheimer's disease is not yet known.
Alzheimer's disease is always fatal.
1. Alzheimer's disease is the most common form of dementia, accounting for as much as 70% of all cases of dementia.
2. Age is one of the most important risk factors for Alzheimer's disease. The percentage of persons suffering from Alzheimer's disease doubles every 5 years beyond the age of 65.
3. Women are more likely to develop the disease than men are – in part, because women live longer.
4. People who have a brother, sister, or parent suffering from Alzheimer's disease have a slightly higher chance of developing the disease. Right now about 3 percent have a proven hereditary link (genetics).
5. Heredity plays a much larger role in early-onset (before age 65) Alzheimer's. About 500,000 Americans suffer from early onset Alzheimer's. The number is growing.
Alzheimer's Disease Symptoms
1. Memory loss
2. Changes in mood or behavior
3. Changes in personality
4. Loss of initiative
5. Difficulty performing familiar tasks
6. Problems with language
7. Disorientation to time and place
8. Poor or decreased judgment
10. Problems with abstract thinking
11. Changes in gait or walking
12. Misplacing things
Alzheimer's symptoms are often subtle at first. They start with slight memory loss, subtle changes in behavior, and confusion.
As Alzheimer's progresses memory problems persist and worsen.
The 7 Stages of Alzheimer's
How the Loss of Memory Works in Alzheimer’s, and How Understanding This Could Help You
People with Alzheimer's disease often:
One early sign of Alzheimer's is the inability to balance a checkbook or properly manage finances. Eventually this worsens until a person has trouble recognizing and dealing with numbers.
- Repeat themselves
- Forget conversations
- Routinely misplace things, often putting them in illogical locations
- Have problems with abstract thinking
- Are unable to maintain a schedule or keep appointments
- Eventually forget the names of family members and everyday objects
Disorientation is another early sign of Alzheimer's. The inability to drive to and locate familiar places. The inability to find the bathroom in the home of a close friend or relative.
Persons's suffering from Alzheimer's disease often lose their sense of time, days, dates, and years.
They can find themselves lost in familiar surroundings.
Hoarding can be an early sign of Alzheimer's. Continually buying items like toilet paper, tooth paste, shampoo, or salad dressing can be a sign of mild cognitive impairment, Alzheimer's or dementia.
Personality changes can be an early sign of Alzheimer's. Constant worries about money. Accusing others of stealing or people talking about them behind their back are examples.
1. Mood swings
2. Distrust in others
3. Increased stubbornness
4. Social withdrawal
are all signs of Alzheimer's disease.
Alzheimer's Disease Causes
No single factor has been identified as the cause of Alzheimer's disease.
Currently, scientists believe that it may take a combination of genetic, lifestyle and environmental factors to trigger the onset of Alzheimer's disease.
The causes of Alzheimer's disease are not well understood.
The affects of Alzheimer's are well understood, Alzheimer's disease damages and kills the brain.
The ultimate cause of neuron death in Alzheimer's isn't known, evidence suggests that the abnormal processing of beta-amyloid protein may be the culprit.
The internal support structure for brain cells depends on the normal functioning of a protein called tau. In people with Alzheimer's, threads of tau protein undergo alterations that cause them to become twisted. Many researchers believe this may seriously damage neurons, causing them to die.
Alzheimer's usually affects people older than 65, but can affect those younger than 40. Less than 5 percent of people between 65 and 74 have Alzheimer's. For people 85 and older, that number jumps to nearly 50 percent.
In advanced Alzheimer's disease, people may lose all ability to care for themselves. This can make them more prone to additional health problems such as:
1. Pneumonia. Difficulty swallowing food and liquids may cause people with Alzheimer's to inhale (aspirate) some of what they eat and drink into their airways and lungs, which can lead to pneumonia.
2. Infections. Urinary incontinence which increases the risk of urinary tract infections. Untreated urinary tract infections can lead to more-serious, life-threatening infections.
3. Injuries from falls. People with Alzheimer's may become disoriented, increasing their risk of falls. Falls can lead to fractures. In addition, falls are a common cause of serious head injuries, such as bleeding in the brain.
Alzheimer's Disease Tests and Alzheimer's Diagnosis
Doctors can diagnose Alzheimer's disease. However, Alzheimer's disease can only be diagnosed with complete accuracy after death via a brain autopsy.
To help distinguish Alzheimer's disease from other causes of memory loss, doctors typically rely on the following types of tests.
Blood tests may be done to help doctors rule out other potential causes of the dementia, such as thyroid disorders or vitamin deficiencies.
Sometimes doctors undertake a more extensive assessment of thinking and memory skills. This type of testing, which can take several hours to complete, is especially helpful in trying to detect Alzheimer's and other dementias at an early stage.
By looking at images of the brain, doctors may be able to pinpoint any visible abnormalities — such as clots, bleeding or tumors — that may be causing signs and symptoms.
Magnetic resonance imaging (MRI). An MRI machine uses radio waves and a strong magnetic field to produce detailed images of your brain. The entire procedure can take an hour or more. MRIs are painless, but some people feel claustrophobic in the machine.
Positron emission tomography (PET) can reveal areas of the brain that may be less active and the density of amyloid plaques.
Computerized tomography (CT). For a CT scan, you lie on a narrow table that slides into a small chamber. X-rays pass through your body from various angles, and a computer uses this information to create cross-sectional images, or slices, of your brain. The test is painless and takes about 20 minutes.
Alzheimer's Disease Treatments and Alzheimer's Drugs
Currently, there is no cure for Alzheimer's disease.
Only two types of medications have been proved to slow the cognitive decline associated with Alzheimer's.
This group of medications — which includes donepezil (Aricept), rivastigmine (Exelon) and galantamine (Razadyne) — works by improving the levels of neurotransmitters in the brain.
Unfortunately, cholinesterase inhibitors don't work for everyone. Only about half the people who take these drugs show improvement. Some people are forced to stop taking these medications due to side effects, which include diarrhea, nausea and vomiting.
The first drug approved to treat moderate to severe stages of Alzheimer's, memantine (Namenda) protects brain cells from damage caused by the chemical messenger glutamate.
Namenda is often used in combination with a cholinesterase inhibitor. Memantine's most common side effect is dizziness, although it also appears to increase agitation and delusional behavior in some people.
Lifestyle and home remedies
A healthy lifestyle may help to prevent or postpone the development of Alzheimer's disease. Because Alzheimer's is most common in people over the age of 80, delaying the onset of the disease could increase the probability that people will die of other causes before Alzheimer's has a chance to develop.
Eat your veggies
Maintaining a healthy weight and eating a healthy diet might reduce the risk of developing Alzheimer's disease.
Eating a Mediterranean diet is often suggested:
Exercise your body
- Lots of fruits and vegetables
- Fish or poultry, instead of red meat
- Whole-grain breads and cereals
- Alternate sources of proteins, such as beans, nuts and seeds
- More olive oil and less saturated fat
Higher levels of physical activity have been associated with a lower incidence of Alzheimer's disease.
Exercise your brain
Maintaining mental fitness may delay onset of dementia. Some research shows that lifelong mental exercise and learning may promote the growth of additional synapses, the connections between neurons, and delay the onset of dementia.
Alzheimer's Disease Prevention
Right now, there's no proven way to prevent the onset of Alzheimer's disease.
Alzheimer's disease is a progressive disease that destroys memory and other important mental functions. At first, someone with Alzheimer's disease may notice mild confusion and difficulty remembering. Eventually, people with the disease may even forget important people in their lives and undergo dramatic personality changes.
Alzheimer's disease is the most common cause of dementia — a group of brain disorders that cause the loss of intellectual and social skills. In Alzheimer's disease, the brain cells degenerate and die, causing a steady decline in memory and mental function. ~ Mayo Clinic
Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills, and eventually the ability to carry out the simplest tasks. In most people with Alzheimer’s, symptoms first appear in their mid-60s. Estimates vary, but experts suggest that more than 5 million Americans may have Alzheimer’s.
Alzheimer's disease is currently ranked as the sixth leading cause of death in the United States, but recent estimates indicate that the disorder may rank third, just behind heart disease and cancer, as a cause of death for older people. ~ National Institute on Aging
