What is Alzheimer's disease?
Alzheimer's disease is a brain disease that causes the degeneration of nerve cells and advanced death. Gradually, the disease spreads: it affects new areas of the brain and causes some brain function loss. The disease is called neurodegenerative because it causes a persistent loss of neurons. That its covering rises with age.
How does Alzheimer's disease develop?
In general, Alzheimer's disease is characterized by cognitive decline. At first, it is especially evident that the memory is damaged. Over time, other upper functions of the brain are also harmed, such as orientation, reasoning, and reasoning. With the progression of the brain degeneration, the patient's motor activity is also damaged, as well as the ability to walk, eating and controlling the closing. In the advanced stages, the patient becomes powerless and needs help with all his actions.
The lesions first reach the brain areas involved in memory. Gradually, they will develop and spread to other areas of the brain, which are responsible for cognitive skills, expression skills (language), logical thinking, motor coordination…
A person's life expectancy can range from three to twelve years or more depending on the phase of Alzheimer's disease to which he is diagnosed.
Tpachtot the disease and its symptoms
1 – Early stage:
At this stage, there is a certain difficulty in short-term memory and the possibility of learning new information, difficulty in finding certain words and terms, and in abstract thinking (to Mel solving a riddle). People associate this with "age problems" and do not usually turn to medical diagnoses. Some people develop because of these signs of anxiety and then some will turn to diagnosis.
2 – A light stage
At this stage, further deterioration in the area of memory and disturbance in the course of orientation, difficulty in managing tasks, slow motor and general thought, repeats questions. The patient's awareness can cause anxiety and symptoms of depression. This is the stage in which the diagnosis is performed in most patients.
3 – Medium Stage
At this stage, there is another worsening of memory, an interruption of logical thinking, and in response to sensory stimuli. It develops a difficulty in performing daily complex activities such as apparel and bathing and a close identification. In some patients there may be behavioral symptoms such as false thoughts, impulsive behavior, and sometimes dangerous.
4 – Difficult stage
A severe disturbance in memory and orientation in all respects, inability to identify people including family members, need complete help in all day-to-day activities, communication with the patient goes and disappears. The movement's capacity is gone.
