Dementia - a serious intellectual and behavioral human disorders which lead to the loss of their basic skills in everyday life.

dementia, or dementia, usually occurs in older people.About 5% of people over age 65 have the disease.

Causes Dementia

main cause of the disease is the destruction of neurons (nerve cells) as a result of lack of food or blood vessels formation in the brain of toxic sediments.Sometimes the cause of dementia is the development of the disease, which leads to pathologies of the nervous system, the so-called secondary dementia.

reasons contributing to the development of the disease:

  • cerebrovascular disease - chronic cerebral ischemia, multiple heart attacks, stroke;
  • diseases of the nervous system, leading to brain cell death - Alzheimer's disease, Huntington's chorea, Parkinson's disease;
  • intoxication drugs - holinolitikami, neur
    oleptics, benzodiazepines, barbiturates;
  • intoxication salts of certain metals - aluminum, copper and zinc;
  • neuroinfections - multiple sclerosis, HIV, paralysis, meningoencephalitis, Creutzfeldt-Jakob disease;
  • traumatic brain injury;
  • brain tumor.

Symptoms of dementia

There are certain signs that indicate the development of this disease.

1.Uhudshenie memory.The man deteriorating memory of current and recent events that have a negative impact on daily life.At the same time the memory of ancient events are usually fully preserved.

2.Problemy thinking.This leads to the symptom of dementia that patient becomes difficult to solve some common tasks.Search solutions is slower quickly tires.

3.Orientirovka.Usually the patient has difficulty with orientation in time.The orientation in familiar terrain persists long enough.

4.Narusheniya communication.A symptom of dementia is that a person becomes dependent on others in performing daily functions.Its beginning to weigh on some of the social relations.

5.Peremeny behavior.The patient gradually lost interest in hobbies, which occupied it before.He is experiencing domestic difficulties, it becomes careless, sloppy.Even courting a person needs constant reminders.

In mild dementia patient loses skills, he has reduced social activities, reduced interest in the outside world.But at the same time, it is normally oriented in familiar surroundings, he is able to take care of themselves.

moderate dementia characterized by the fact that the patient loses skills to use household appliances, can not stay long one.Although it retains the basic skills of self-service in the home, it needs constant tips from others.

permanently totally dependent on others for all daily activities In severe dementia patient.

Vascular dementia

intellectual and behavioral disorders the person who caused the pathology of the brain blood circulation, called vascular dementia.

The resulting vascular damage in certain areas of the brain, neurons do not receive oxygen and nutrients that are necessary for their normal operation.First, the brain is able to compensate for the ongoing violations, and they do not appear.Then dementia symptoms - impaired memory, thinking, speech quality.Against the background of these disorders begin to change human behavior and its autonomy decreases.

The share of vascular dementia in pure form accounts for about 10-15% of all cases of the disease in the elderly.However, the disease is often combined with Alzheimer (disorder in which brain cells gradually die).

The cause of vascular dementia is called by two major factors:

  • acute cerebral circulatory disorders such as stroke, heart attack;
  • chronic insufficiency of cerebral blood flow.

These reasons often reinforce one another, resulting in a more pronounced symptoms of dementia.

The characteristic features of vascular dementia include violation of walk - shuffling, slow gait.In addition, there may be the appearance of differences in reflexes left and right limbs hemiparesis (weakening of the limbs strength).

senile dementia

senile or senile dementia usually occurs in older people 65-85 years.

reason for developing the disease experts call pathological aging of the brain and body.Of great importance in the appearance of the disease belongs to hereditary factors.Furthermore, senile dementia of reasons often lack autoimmune and immune system, resulting in pathological changes occur the central nervous system.

Patients with senile dementia manifest violation of thinking, which gradually grow and eventually lead to the impossibility of understanding the world, misunderstanding even domestic issues.In the later stages of the disease it becomes a constant talkativeness, perception of reality becomes blurred and blurred.

frequent symptom of dementia is becoming a so-called "shift in the past."The patient does not remember the events of the last ten years, sometimes the second half of life, but come to life events distant youth, which he perceives as real.In this chamber they perceive for an apartment, the surrounding people mistaken for dead relatives and acquaintances.

Often patients of senile dementia much sleep during the day.Their nocturnal sleeplessness is accompanied by moving, fussiness.

behavior of patients with senile dementia becomes fussy, stupid over time.They can not take care of themselves, become careless, helpless in domestic affairs.Patients often go out of the house and can not find the way back, may commit arson of property.

Senile dementia is wavy or continuously progressive course.Some of the patients die before the stage of senility when they have only a few biological needs remain.

treatment of disease

treatment of dementia depends on the reasons for which it was called.Many kinds of diseases are irreversible, such as senile dementia.In this case, therapy aims to stop or slow down the process of neuronal cell death, reduce the appearance of symptoms of the disease.To do this, in the treatment of dementia use medication, special diet and moderate physical and mental patient load.

Treatment of vascular dementia is aimed at eliminating the causes of neuronal death (atherosclerosis, hypertension).In addition to drug therapy patients need proper diet, avoiding alcohol and smoking, moderate mental and physical stress.

Timely competent treatment of dementia can slow its development and significantly delay the onset of severe forms of the disease.
