It is common to complain about poor memory. Does it mean Alzheimer’s disease if you feel that your memory is not good? Of course not. Let’s look at the characteristics of general forgetfulness: 1. only forgetting a certain part of things, usually remembered after being reminded; 2. the cognitive ability of time, place, people and the surrounding environment has not been reduced; 3. can take care of themselves in daily life; 4. quite distressed about memory loss, in order not to miss things, often remember a memo.
In contrast, patients with Alzheimer’s disease: 1) cannot recall what happened even after repeated reminders; 2) have lost the ability to recognize their surroundings and do not know where they are; 3) gradually lose the ability to take care of themselves; 4) become increasingly slow in thinking and poor in language.
So in summary, Alzheimer’s disease patients forget not only the details of the event, but the event itself. They do not only have memory problems, but they are also accompanied by changes in other cognitive abilities, including the ability to judge time and space, language skills, etc.
