Fortunately, however, there are more and more specialized centers appearing across the world. So far, doctors who have tested for Alzheimer’s disease and other similar forms of dementia have had roughly a 90% average, when it comes to correctly diagnosing this brain dysfunction. This is determined through a series of tests, including questioning the patient (or family) about general health, any past medical problems that s/he might have, and in regards to their ability to carry out daily activities. Tests involving memory, counting, attention span, language and problem-solving abilities are also given.

Sometimes, medical tests will be given, such as blood work, urinalysis, or a test of the spinal fluid may be performed. Occasionally, brain scans are done as well. While these cannot help prove that the patient is suffering from dementia, they are helpful in that they rule out other diseases that can cause similar symptoms, such as diseases of the thyroid gland, cancers, or drug-related reactions.

It is unknown what, exactly, causes dementia. It is believed that nerve cells are deadened, in areas of the brain that are vital to memory and there are many theories as to what might cause this. Recent research suggests that there may be a link to the gene that creates apolipoprotein in the human body, which helps to carry cholesterol in the blood. Considering some of the risk factors involved, it is believed that there may be a link between heart disease, cholesterol and dementia, though research is still inconclusive.

Stripping its victims of their memories, their independence, and their lives, dementia is a cruel and frightening disease. There is no way to stop dementia, once it begins, and there is no known cure for it, to date. Researchers do agree, however, that getting regular exercise and maintaining a healthy diet will help to lessen your risks of getting dementia. If you think that you are at risk of developing this condition, take the steps now to protect yourself and those you love, not only through education, but also by promoting a safer and healthier lifestyle.
