Alzheimer’s disease can be roughly divided into three stages: forgetfulness, confusion, and dementia. In the early stage of symptoms, many patients often think that memory deterioration is normal aging, and if they don’t take the initiative to go to the hospital for diagnosis and treatment, the symptoms of forgetfulness will become more serious. According to statistics, about 60% of initial patients have lost experience.
Elderly people suffering from Alzheimer’s disease usually have the following signs
1. Memory impairment
Memory impairment appears in the early stage, especially near memory impairment. It is impossible to recall what happened dozens of hours or even minutes ago. The patient’s daily life is characterized by “losing things” and “forgetting after speaking”, asking the same questions repeatedly, or telling the same things repeatedly.
2. Language barriers
Difficulty in finding words is often the earliest language disorder in Alzheimer’s disease. It is mainly manifested in the lack of proper words when speaking, or the difficulty in finding words and excessive explanations to express, and eventually become nagging.
3. Visual-spatial skills impairment
In the early stage of Alzheimer’s disease, there may be visual-spatial skills impairment, and its symptoms include the inability to accurately determine the location of objects. Some people with Alzheimer’s disease may get lost in a familiar environment in the early stages of the disease.
4. Difficulty writing
Due to writing difficulties, the content of the words written is not expressing the meaning. For example, the meaning of the letter can not be clearly written. This is often the first symptom that attracts the attention of family members, especially some elderly people with better cultural accomplishments. Research suggests that writing errors are related to memory impairment.
5. Agnosia and apraxia
Agnosia refers to the patient’s inability to recognize objects, even though they can be recognized by tactile or visual elements at this time; apraxia refers to the inability to perform the purposeful actions that have been learned although they have normal ability and subjective desires.
6. Personality changes
Personality changes are very significant in some patients, who are extremely sensitive and suspicious or fearful or become more irritable and stubborn.
7. Behavior change
The movement of patients with Alzheimer’s disease is often normal in the early stage, and the behavior of patients in the middle of the disease can be seen as naive and clumsy, and they often perform ineffective and purposeless labor.
