What are the most common causes of dementia?

dementia is a condition in which two or more important functions of a person's brain are reduced. The areas that may be affected include memory, the ability to maintain knowledge, coordination, judgment and personality. Sometimes the causes of dementia are unknown, but in other cases the causes of dementia are Alzheimer's disease, AIDS, drug interactions or some types of poisoning. Depending on the type of dementia, one can become paranoid, may lose the ability to communicate or see hallucinations.

Alzheimer's disease is one of the most common causes of dementia. This disease is called "progressive" because the condition usually deteriorates over time. While the exact causes of Alzheimer's disease are unknown, the result is that certain types of brain cells are damaged or killed. The plaques are pieces of protein that are usually eliminated from the brain, but become hard and cannot be dissolved in the brain of patients with Alzheimer's disease. In addition, Proftein "Tau" in structures known as SPLeti, which normally helps transport of substances such as nutrients in nerve cells, ceases to work properly in Alzheimer's patients.

Not all forms of dementia are progressive. Some are able to be stopped and in some cases turned. The causes of dementia that can be "cured" include heavy metal poisoning, reactions to drugs and responses to drug interactions. Other causes of dementia that can be reversed include dementia due to the inability to absorb vitamin B-12, dementia caused by thyroid problems and dementia resulting from brain tumors.

There are forms of dementia that are associated with other health conditions. Like Alzheimer's disease, the symptoms of these forms of dementia cannot be reversed. One of the causes of this type of dementia is human immunodeficiency virus (HIV). When HIV develops on the acquired Immsyndrome UNE deficiency or AIDS, patients may develop the dementia SPRun with HIV, which can lead to memory loss and apathy.

dementia treatment varies according to the individual. Most progressive dementia treatment focuses on symptoms because progressive dementia cannot be cured. In a patient with Alzheimer's disease, the doctor may prescribe cholinesterase inhibitors to help maintain memories, improve the decision -making process and help improve or maintain learning ability. The physician may also prescribe medicines to treat health conditions such as drug treatment drugs, high cholesterol or high blood pressure. Doctors can also suggest that a person who has dementia gets advice, or joins the support group after diagnosis to help with this disease as long as possible.
