What's wrong with the old man always being stupid?

Alzheimer's disease makes you stupid.

It should belong to Alzheimer's disease. The course of Alzheimer's disease progresses slowly, lasting an average of 9 years from early stage to late stage, but the length of the course varies greatly from patient to patient.

Early stage: patients are confused and forgetful, sometimes they can't remember what they want to say, but they forget half of it, and they don't remember what happened not long ago or what they said. However, he clearly remembers what happened a long time ago.

Mid-term: Daily activities need more and more help from others. Patients may not know their families at first, get lost in familiar places, and even forget how to do simple things, such as dressing and bathing. In addition, patients show irritability, irritability and unpredictability.

Late stage: complete loss of memory, judgment and reasoning ability. Everyday life needs to be taken care of by others. Clinically, the disease is divided into three stages: early stage, middle stage and late stage. Early performance is generally forgetfulness, and normal social interaction can be carried out at ordinary times, so it is often ignored by patients and their families. At this time, the prominent symptom of the elderly is memory disorder (especially recent memory). Patients always forget what happened just now, but remember the past clearly. Family members sometimes mistakenly think that patients have a good memory. Specific examples are as follows:

1, forget when you do it, and forget when you leave. I put salt in the cooking, but I don't know if I put it. Obviously locked the door and went out, but I felt the door was half open; Forgot to bring a basket or money when shopping; I went to pick up my grandson and bought a bottle of vinegar. My grandson took the vinegar but didn't buy it.

2, the words are not satisfactory, embarrassing. I wanted to express one meaning, but when I said it, it was another meaning. I always say the same thing over and over again.

3. Forget the names of acquaintances. Walking in the street, I am an old acquaintance but I can't name him.

4. doubt. I can't find my things, and I always suspect that someone else stole them.

5. Emotional apathy. I'm not interested in anything, even what I used to be interested in.

6. the computing power is declining. Shopping on the street is a very simple account, which is very laborious to calculate, or even impossible to calculate at all.

In patients with intermediate Alzheimer's disease, both distant memory and near memory are obviously impaired. For example, if you forget the phone number you have used for many years, you can't remember when you got married. Some old people show obvious personality and behavior changes. For example, they used to be gentle and generous, but now they are short-tempered and narrow-minded I used to have a bad temper, but now I am obedient. Most patients are not interested in the things around them, lack enthusiasm, and can't finish their accustomed work. Some patients show anxiety, such as walking around aimlessly indoors, or getting up in the middle of the night to grope around, opening and closing doors and moving things. Some patients may get lost if they go a little further, and some even get lost in familiar environments.

In the late stage, the patient doesn't know the surrounding environment, and he doesn't know the year, month and season. It is difficult to add and subtract within 10. He needs to take care of his daily life and can only remember the names of one or two people, such as himself or his spouse.

The first period: the forgetting period. During this period, he was particularly forgetful. At the same time, his memory was damaged, and his computing ability, cognitive ability and directional ability gradually appeared obstacles, and his range of activities was narrowed, but he was still able to maintain his daily life without the help of others. This period is the longest duration of this disease.

The second period: the period of insanity. During this period, dementia continued to get worse, and the condition took a turn for the worse, and cognitive function further declined, accompanied by agnosia, aphasia and apraxia. Thinking and emotional disorders and personality changes are obvious, and behavior is obviously abnormal. Some patients may have hyperactivity, face covering and increased muscle tension, as well as hemiplegia and epilepsy. It is difficult to take care of yourself in daily life and need help from others.

Stage 3: Dementia stage: The patient is severely demented, in a state of complete silence, complete bed rest and complete loss of self-care ability. Often accompanied by cachexia, myotonia and urinary incontinence.
