2) Mild (or Early) stage
In this stage, the doctor may be able to reach a definitive diagnosis. As the disease progresses, the problems in memory and learning increase, and the patient start to forget the names of his family and friends. The patient usually doesn’t remember the episodes of memory loss; thus, family and close people only can notice these changes. Alzheimer’s disease, in its early stage, affects the recent memory more than the older memory.
Also, during this stage, the patient may experience difficulty in financial issues, such as paying bills. He takes more than usual to do his daily tasks, and he may get lost in familiar places. He also may show some personality and behavior changes.
Some language problems may occur in this stage; the patient begins to lose the vocabulary and the word fluency, which leads to poor spoken and written language. During this stage, the patient is still able to deliver the basic ideas adequately. But, unnoticed problems in the more complex tasks may be present, such as writing, drawing, planning, balance, and coordination. Also, he may experience some unusual confusion.
With disease progression, the patient may start to need assistance in his daily activities.
In most cases, memory problems are more evident during this stage.
In this stage, the family and the close people around the patient has a vital role because they can notice the changes before the patient himself, which can help the early diagnosis and management of the case.
