World Alzheimer’s Month is the international campaign every September to raise awareness and challenge the stigma that surrounds dementia and to create an awareness of the disease of the elderly. World Alzheimer Day is on 21 September each year.
What is Alzheimer’s Disease?
Alzheimer’s disease is a neurological disorder in which the death of brain cells causes memory loss and cognitive decline. A neurodegenerative type of dementia, the disease starts mild and gets progressively worse. Alzheimer’s disease was first described by Alois Alzheimer in 1906.
What is Dementia?
Dementia is a collective name for progressive brain syndromes which affect memory, thinking, behaviour and emotion. Dementia is the leading cause of disability and dependency among the elderly. Alzheimer’s disease is the most common cause of dementia and accounts for 50%-75% of all cases.
How Does this Degenerative Disease of the Elderly Affect the Brain Cells to Cause Memory Loss?
In this condition brain cells and nerves is disrupted transmitting or carrying messages in the brain, particularly those responsible for storing memories. The nerve cells die in particular regions of the brain. The brain shrinks as gaps develop in areas which are responsible for storing and retrieving new information. These changes affect an individual to remember, speak, think and make decisions. The production of certain chemicals in the brain, such as acetylcholine is also affected.
Symptoms of Alzheimer’s Diseases
Typically, Alzheimer’s disease begins with lapses of memory, difficulty in finding the right words for everyday objects or mood swings.
As Alzheimer progresses, the person may:
- Routinely forget recent events, names and faces and have difficulty in understanding what is being said
- Become confused when handling money or driving a car
- Undergo personality changes, appearing to no longer care about those around them
- Experience mood swings and burst into tears for no apparent reason, or become convinced that someone is trying to harm them
- As the disease progresses, people may also
- Adopt unsettling behaviour like getting up in the middle of the night or wander off and become lost
- Lose their inhibitions and sense of suitable behaviour, undress in public or make inappropriate sexual advances.
Causes of Alzheimer’s Diseases
Alzheimer’s is caused by brain cell death and total brain size shrinks with Alzheimer’s – the tissue has progressively fewer nerve cells and connections.
Nerve cells (neurons) in the brain in Alzheimer are under a microscopic look like ‘plaques’ and ‘tangles’ between and within brain cells. These are abnormal protein clumps,
Researchers do not fully understand why the changes that lead to Alzheimer’s disease occur. Several different factors are believed to be involved. Risk factors for developing the condition include aging, a family history of Alzheimer, and carrying certain genes.
Diagnosis of Alzheimer’s Disease
Symptoms can be diagnosed at any stage of Alzheimer’s dementia and the progression through the stages of the disease is monitored after an initial diagnosis, too, when the developing symptoms dictate how care is managed.
For doctors to make an initial diagnosis of Alzheimer’s disease, they must first be satisfied that there is dementia. It involves cognitive or behavioural symptoms that show a decline from previous levels of “functioning and performing” and interfere with ability “to function at work or at usual activities.”
TWO of the five symptom areas listed below as per from guidelines jointly produced by the National Institute on Aging and the Alzheimer Association diagnose a patient:
1. Worsened ability to take in and remember new information, for example: asking repeated questions
2. Impairments to reasoning, complex tasking, exercising judgment:
3. Impaired visuospatial abilities (but not, for example, due to eye sight problems): Inability to recognize faces or common objects or to find objects in direct view
4. Impaired speaking, reading and writing: Difficulty thinking of common words while speaking, hesitations
5. Changes in personality and behaviour:
- Out-of-character mood changes, including agitation; less interest, motivation or initiative; apathy; social withdrawal
- Loss of empathy
- Obsessive or socially unacceptable behaviour.
Stages of Alzheimer’s Disease
- Preclinical (no signs or symptoms yet)
- Mild cognitive impairment
- Dementia.
The Alzheimer’s Association has broken this down further, describing seven stages along a continuum of cognitive decline based on symptom severity – from a state of no impairment, through mild and moderate decline, and eventually reaching “very severe decline.”
Some Tests Carried out are:
- Tests of blood and urine samples
- Arranging brain scans (possibly including CT, MRI and EEG).
- Sometimes dementia symptoms are related to an inherited disorder such as Huntington’s disease, so genetic testing may be done.
- There must be memory loss and impairment in one other area of cognition for a diagnosis of dementia such as Alzheimer’s to be made. Cognitive testing is a vital diagnostic tool
- Normal cognitive health – score above 26
- Mild-to-moderate Alzheimer’s – below 26
- Moderate – below 20 but above 10
- Severe – score under 10.
Treatment of Alzheimer’s Disease
There is no known cure for Alzheimer’s disease – the death of brain cells in the dementia cannot be halted or reversed.
Effective management of these conditions includes:
- Activities and/or programs of adult day care
- Support groups and services.
- Drug therapy There are four drugs in a class called cholinesterase inhibitor approved for symptomatic relief
Prevention of Alzheimer’s Disease
There is a lot of research into risk factors associated with Alzheimer’s disease, so there may be lifestyle measures we can take to potentially reduce our risk and enjoy a healthier life more generally.
