Alzheimer’s Disease: What You Need to Know


Alzheimer’s disease is the most common dementia. The disease incidence correlates strongly with age and usually hit people older than 65 years of the disease. There are also cases of Alzheimer’s disease at a younger age, and you can get on very rare occasions, the disease is already at 50 years old.

The cause of Alzheimer’s disease is not entirely known, but a change in the sales of a protein called beta-amyloid is considered a critical component in the development of the disease. The symptoms will be usually insidious, and progress is slow. It may take several years before symptoms get noticeable to seek help.


In Alzheimer’s disease affect multiple cognitive (intellectual) functions, such as memory, thinking, orientation and language. If the disease onset in older age is memory disorders, the most common and perhaps many times the only symptom. In the younger one has a greater mix of symptoms and it is common to mainly language ability is impaired in this population. It is hard to find words for what things named. The more the disease progresses, the more and more severe cognitive problems experienced man. In the advanced stage of Alzheimer’s disease has been significantly reduced memory and the memory material has been left far back in time. The first memory disorder that occurs is called episodic, short-term memory disorder, which means that it has difficulty remembering things close in time concerning yourself. For example, to remember what you had for breakfast, what to buy at the store and agreements on time. Often repeat them because you forgot what you said earlier.

Risk Factors

There are some risk factors for developing Alzheimer’s disease, and old age is the strongest of these. Of the risk factors that can influence, high blood pressure and high blood cholesterol in midlife, this increases the risk that 25-30 years later fall ill with Alzheimer’s disease. Another risk factor is heredity, where the fact that you have a close relative who is sick, the risk of a self of contracting something. There is also the risk genes, which means there is a risk gene that increases the risk of contracting the disease if at the same time designated for other risk factors. Other proposed risk factors include low education, diabetes, and repeated blows to the head.

Pharmacological treatment with drugs

There is symptom-relieving medication for Alzheimer’s disease. They called acetylcholinesterase inhibitors and is sold under the name Reminyl, Exelon, and Aricept. There is also another type of drug called Ebixa. These drugs relieve the symptoms for a time but do not affect the course of disease in the long term. Many patients benefit greatly from those in one to two years, and they are associated with relatively mild side effects, which usually consists of nausea, vomiting, and diarrhea. You can also use the patch to administer the drug and then you have the lower frequency side.

New treatments

Recently, also increased awareness when it comes to other types of treatments and remedies, for example, it seems that Omega 3 fatty acids may have a protective effect. We also know that vitamin B deficiency is associated with Alzheimer’s disease, but in many extensive studies have attempted to treat the disease with vitamin B without effect. Why is this way is unclear? They have tried to develop the new medicine, particularly some resources spent on finding immunological treatment in the form of antibodies against beta-amyloid. So far, no breakthrough was reached, possibly due to the type of therapy must be initiated very early in the disease process.


Our ability to diagnose Alzheimer’s disease has also increased lately, and taking a sample of spinal fluid and which measure proteins in this enhanced ability to identify the disease even very early. A neuroradiological investigation in the form of computed tomography or magnetic resonance imaging is also of great value. We know that certain brain lesions typical of the disease. A shrinking of the middle temporal lobes is an example of this.
