As the exact cause of Alzheimer's disease is still unknown, there's no certain way to prevent the condition.
The causes probably include a combination of age-related changes in the brain, along with genetic, environmental, and lifestyle factors.
Alzheimer's disease is thought to be caused by the abnormal build-up of proteins in and around brain cells. One of the proteins involved is called amyloid, deposits of which form plaques around brain cells. The other protein is called tau, deposits of which form tangles within brain cells.
Lower levels of education, higher rates of poverty, and greater exposure to adversity and discrimination may also increase risk of Alzheimer's disease. Among all races, women are nearly two times more likely to be affected by Alzheimer's disease than men. The difference is due primarily to women living longer.
Alzheimer's disease has been associated with low levels of the neurotransmitter acetylcholine. Because choline is a precursor to acetylcholine, scientists have tested if choline supplements can increase acetylcholine levels in the brains of Alzheimer's patients.
There have also been other suggestions as to how coffee can help against dementia. Research has shown that caffeinated coffee increases production of granulocyte-colony stimulating factor, which helps the brain in several ways.
Phytochemicals
Phytochemicals found in bananas help preserve nerve tissue against neurotoxins, which deteriorate nervous tissue when exposed to its substance. This may also help in preventing neurological diseases such as Alzheimer's disease.
The risk of developing Alzheimer's or vascular dementia appears to be increased by many conditions that damage the heart and blood vessels. These include heart disease, diabetes, stroke, high blood pressure and high cholesterol. Work with your doctor to monitor your heart health and treat any problems that arise.
If I am affected by stress, should I worry about getting dementia? The current evidence indicates that while chronic stress may play a role in the development or progression of dementia, it does not necessarily cause dementia.
Is Alzheimer's Genetic? Family history is not necessary for an individual to develop Alzheimer's. However, research shows that those who have a parent or sibling with Alzheimer's are more likely to develop the disease than those who do not have a first-degree relative with Alzheimer's.
Importantly, people who develop Alzheimer's do not always have a history of the disease in their families. Still, those who have a parent or sibling diagnosed with the disease have a higher risk of developing Alzheimer's than those without that association.
Researchers followed 957 older adults, average age 65, who were part of the Singapore Longitudinal Aging Study. Of these, 69% drank tea on a frequent basis. After a five-year period, the researchers found that the tea drinkers had a 50% lower risk of dementia.
Offer different types of drink throughout the day such as tea, coffee, hot and cold milky drinks, fruit juice or smoothies, soup, squash and water. Make sure the cup or glass is suitable – not too heavy or a difficult shape.
Many people affected by dementia are concerned that they may inherit or pass on dementia. The majority of dementia is not inherited by children and grandchildren. In rarer types of dementia there may be a strong genetic link, but these are only a tiny proportion of overall cases of dementia.
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.
Vitamin D also plays an important role in neurodegenerative processes. Its deficiency is a genetic risk factor for AD, Parkinson's disease, multiple sclerosis, and vascular dementia [45].
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.
1. Memory loss that disrupts daily life: forgetting events, repeating yourself or relying on more aids to help you remember (like sticky notes or reminders). 2. Challenges in planning or solving problems: having trouble paying bills or cooking recipes you have used for years.
The Self-Administered Gerocognitive Exam, known as SAGE, is a brief, pen-and-paper cognitive assessment tool designed to detect the early signs of cognitive, memory, or thinking impairments. The test evaluates your thinking abilities. This can help your doctors understand how well your brain is functioning.
Problems can include wandering and getting lost, trouble handling money and paying bills, repeating questions, taking longer to complete normal daily tasks, and personality and behavior changes.
