Q: 

what causes Alzheimer''s disease?

A: Researchers do not know the exact cause of Alzheimer''s disease, but it likely is due to a variety of genetic and environmental factors. Some factors are suspected to have a role in the development of Alzheimer''s disease. They include: -Age and family history -Certain genes -Abnormal protein deposits in the brain -Certain environmental factors, such as head trauma Brain studies show that chemical and structural changes occur in the brain tissue of people with Alzheimer''s disease. These changes interfere with a person''s ability to process, store, and retrieve information. It is not known why these changes occur....
Q: 

what Is Alzheimer?s disease?

A: Alzheimer’s Disease, also known as Alzheimer Disease, is defined as the neurodegenerative disease which is characterized by restlessness, confusion, impaired memory, as well as disturbances in reasoning, planning, language, coordinating and perception. Alzheimer’s disease is a form of incurable, degenerative and terminal disease that was initially described by German psychiatrist and neuropathologist Alois Alzheimer in 1906. The patient suffering from Alzheimer’s disease is unable to remember about their lives, recognize family member, engage in coordinated movement, communicate properly, or use hygienic conditions like toilet. Alzheimer’s disease is caused due to the failure in the production of acetylcholine (neurotransmitter) or due to excessive production or...


Q: 

what is Alzheimer`s disease?

A: Alzheimer`s disease is a neurodegenerative disease that, over the course of seven to ten years, renders its sufferers unable to remember much about their lives, recognize their loved ones, engage in coordinated movement, speak properly, or use the toilet on their own. Alzheimer`s disease probably does not kill people directly, but impairs their ability to take care of themselves, making them much more susceptible to other ailments and consequently leading to their death. The disease starts with a mild forgetfulness, which gets progressively worse until most of the mental faculties we associate with personality and intelligence are destroyed.. Alzheimer`s disease most frequently strikes between the ages of 65 and 85, and afflicts as many as a third of all people who reach the latter end of...


Q: 

what is Alzheimer''s disease?

A: Alzheimer''s disease is a progressive, irreversible brain disorder with no known cause or cure. It attacks and slowly steals the minds of its victims. Symptoms of the disease include memory loss, confusion, impaired judgment, personality changes, disorientation, and loss of language skills. Always fatal, Alzheimer''s disease is the most common form of irreversible dementia. Alzheimer DISEASE, regenerative brain disease, progressive decline reflected intelligence. First described by German physician A. Alzheimer in 1907, the disease is a common form of acquired dementia (dementia). Only in the U.S. Alzheimer''s affects about 1.5 million. Of a total of 1.3 million people in the U.S. in nursing homes, 30% of people with Alzheimer''s disease. This disease affects people...


Q: 

what neurotransmitter causes alzheimer''s disease?

A: Dementia of the Alzheimer''s Type is not caused by any one particular neurotransmitter. In fact, the causes are multifactorial, ranging from genetic (with changes often found on chrosome #1, chromosome #21, and others) to environmental (various proposed toxins) to psychosocial (with some individual not showing symptoms despite significant changes to brain parenchyma, and others showing significant symptoms in spite of minimal evidence of structural changes to the brain). At any rate, the more one reads, solves puzzles, and otherwise engages in cognitive activities, the less likely they are to show symptoms of this disease. So it''s ''use it or lost it'', as they say!...


Q: 

Alzheimer"s Disease

A: Hello Cynthia, Thank you for writing.   Alzheimer"s is a Kind or Type of Dementia.  There are over 72 different kinds of Dementia based upon their origins. Much like Cancer, Dementia is an "Umbrella" term that encompasses many types.   Some types other than Alzheimer"s are:  Parkinson"s disease, Multi-infarct disease, Pick"s disease, Huntingdon"s disease, etc.   Alzheimer"s disease is a progressive, degenerative brain disease.  "Plaques" (Amyloid proteins) build up on one"s neurotransmitters in the brain and eventually block transmissions.   A good visual to this would be to think about poision oak or vines growing up and around a tree.  Eventually, it can destroy the tree by taking over the tree.   These plagues do the...


Q: 

alzheimer"s disease

A: Hello, Thank you for writing. Alzhiemer"s disease is a TYPE of Dementia.  Much like lung cancer is a TYPE of cancer.   Dementia dieases have many of the same characteristics:  physical/chemical changes of the brain that cause memory loss, personality/behavior changes, loss of physical abilities, etc. Alzheimer"s disease is a physical, deterioration of the brain brought on by amyloid plagues that settle on brain receptors and eventually kill those receptors; thus breaking down brain activity. A visual picture of this might be like ice on telephone wires that gets very heavy and eventually breaks the wires.   The messages can"t go through at that point. The challenge with Alzheimer"s disease is that it destroys the brain differently for different...


Q: 

Alzheimer"s Disease

A: Hi Sue - the only truly definitive test for Alzheimers is a brain biopsy, almost never done, for obvious reasons.  Since a brain biopsy is too invasive and risky,  Alzheimers gets diagnosed by ruling out common possibilities, one by one.   Confusion and memory problems can stem from a host of things including small strokes (so small the person may not show other signs of stroke), drug interactions or side effects, Parkinson"s, thyroid problems, brain tumours, pernicious anemia, depression, low oxygen levels, high fluid pressures in the brain - and a stack of other things. Alzheimer"s is one of the most common causes of confusion in the elderly, but not the only cause - so its always, always worth getting a proper diagnosis. Confusion is never a...


Q: 

Statin Drugs / Alzheimer"s Disease

A: Hi Corra, The current evidence suggests that statin drugs actually reduce a person"s odds of developing dementia from 30-50%. There have been a number of studies with similar findings, and a couple that found no effect. At present, the jury is still out - the roots of progressive dementia can be really complex and hard to study. Here are some typical study results http://www.medicalnewstoday.com/articles/127532.php http://brainposts.blogspot.com/2010/06/can-statin-drugs-prevent-alzheimers.html A person with acute onset dementia that is rapidly progressing may not have Alzheimer"s disease, but may have some other cause of cognitive impairment. Alzheimers tends to develop perniciously and slowly over many years. Quite often, when a person is finally diagnosed (often when the...


Q: 

Do aluminum and mercury additives in vaccines cause alzheimer''s?

A: No!!!! There has not been one single piece of literature published in the scientific literature that shows any correlation between these 2 elements and Alzheimer''s Disease. (but then again I did receive the H1N1 vaccine and it did contain thiomersal so I could have forgotten what I read in the past) btw - Thiomersal is an organomercury compound (approximately 49% mercury by weight) Currently, there is no scientific evidence to suggest that either of these two additives cause Alzheimer''s Disease. While there are some reports of aluminum potentially having some effect, due to in vitro studies, no studies in human beings have found a link between the two. To date, long term vaccine studies have shown no effects on brain function. Thus, the risk of illness due to...
