Dementia - what is it?

dementia - a dementia, is characterized by the degradation of thinking, memory and behavior.Manifestations of dementia are very diverse.Man loses previously acquired for household and professional skills, interests of its fading, thinking becomes logical.In the most severe cases, a person can not realize what happens to him where he is, no longer recognize anyone and needs constant home care.

Depending on the level of social adaptation and means-tested assistance in several forms of dementia: mild, moderate and severe.

  • 3 dementia

mental changes,developing senile dementia associated with irreversible changes in the brain.These changes occur at the cellular level, due to lack of food kills neurons.This condition is called primary dementia.If there is a disease of the nervous system is affected, the disease is called secondary dementia.Such diseases include Alzheimer's disease, Huntington's d

isease, spastic psevdoskleroz (Creutzfeldt-Jakob disease), and others. It is also the cause of dementia can be alcoholism, drug addiction, head injury (especially boxers), and infectious diseases.

In mild form of dementia decreased social activity, patients are forced to leave the job, they become harder to communicate with people, there is apathy.Such a condition can lead to depression, which often masks the initial manifestations of dementia.This person is able to fully take care of themselves.

mild form of dementia - a more severe stage of the disease.Sick people almost completely lose interest in the outside world.There is a loss of habitual skills (self-turn on the TV or a plate they can not).Hygiene practices persist, patients can monitor the physiological needs.So people need supervision and help from loved ones or caregivers.

In severe dementia (this is its last stage) patients become insane, they can not explain anything.Lost absolutely all the skills, even the most simple (to hold a spoon, brush your teeth, patients are not able to).Patients need constant nursing care.Often, patients may resist attempts to help them, which greatly complicates the lives of their loved ones.

This type of dementia is particularly noteworthy because the pathological processes in the brain develops very slowly, and for a long time, the person may not know that the disease has already begun.

of brain disorders is due to disturbances in blood vessels of the brain.Due to lack of oxygen and nutrients, brain cells begin to die.When the withering away of a small number of neurons do not show symptoms of the disease, as other cells in the brain take over part of the functions of dead neurons.But a large part of the brain damage begins manifestations of dementia.

One of the most common causes of vascular dementia - a stroke, and it does not matter, ischemic (cerebral thrombosis) or hemorrhagic (bleeding) the type of cerebrovascular accident happened.Older people often suffer from diseases that increase the risk of dementia: hypertension, coronary heart disease, atherosclerosis, arrhythmias.

manifestations of vascular dementia is usually difficult to identify.Usually I say about this form of dementia when the symptoms appeared after a stroke or heart attack.
Violations of thinking and memory depend on which area of ​​the brain damage occurred.

Unfortunately, irreversible dementia, as irreversible changes in the brain, which became the cause.

patients needed quality care, communication, their favorite things.While maintaining the familiar life of patients there is a possibility for much longer keep their brain function and slow the progression of the disease.Patients need a good diet rich in antioxidants, vitamin, mild mental stress in the early stages of the disease (reading, memorizing and retelling of reading).

treatment of diseases, which result in dementia, helps to slow down the progression of dementia.Typically, patients need monitoring by a cardiologist and a neurologist for the appointment of adequate therapy of cardiovascular diseases.

helps slow the progression of the disease drugs that improve the interneuron communications (Memantine, anticholinesterase agents), as well as to ensure normal blood circulation and metabolism in the brain cells (glycine).

Patients suffering from dementia, your doctor should be observed continuously because the progression of the disease is inevitable, and you may need correction of treatment.Self-treatment of dementia can not be.

Dementia - a test not only for the patients but also their relatives.In many cases, the correct behavior, and the need for adequate assessment of the relatives regarding the duration of treatment depends on the full life of the sick person.
