Alzheimer's disease: salvation none

Non-Alzheimer'S Disease Dementias (Health And Medical Video 2017).

Alzheimer's disease, named after the doctor who first gave her a clear definition refers to degenerative diseases. The reason is the process of destruction of nerve cells in the brain - neurons, but why this happens is still not known for certain. There are no methods for the treatment of senile dementia.

Statistics

Nowadays, people are living much longer because Alzheimer's disease spreads more and more, in 2005 the total number of patients was 24.5 million people, and by 2015 there will be at least 30 million. The age cut shows today suffer from this disease Every fifth person is older than 75 and each other is over 84 years old.

Manifestations of the disease

  • Beginning characterized by decreased concentration, forgetfulness, decreased ability to perceive information.
  • Forgetfulness is progressing, the character is spoiled, the language is depleted, aggression and capriciousness take place.
  • The degradation of memory, speech, motility, and the ability to control their physiological functions are rapidly occurring.
  • A person loses the ability to speak, think, do not remember not oriented in time and space, is unable to eat and drink.
  • After 7-8 years, as a rule, such patients die. Not more than 3% of them live longer than ten years from the start of bright symptoms.

Difficulty diagnostics

The easiest way to diagnose is by the characteristic degradation symptomatology. Additional confirmation can be obtained from the results of MRI and PET research, which it is difficult, but nevertheless, it is possible to consider Alzheimer's characteristic so-called plaques of a special beta-amyloid protein, whose adhesion leads to neuronal pathology.

At present, scientists are working to obtain a strong contrast medium to facilitate these studies.

Attempts of treatment

Therapy is aimed at reducing symptoms. For example, activation of fading neurons with the help of special substances - neurotransmitters, the natural level of which in the brain in Alzheimer's disease is reduced, is applied.

It slightly smoothes out the symptoms, but does not cure the disease. Scientists hope that when a way to prevent the adhesion of beta-amyloid particles is found, it will finally be possible to prevent or reverse this process.
