3) Moderate (or Middle) stage
In this stage, the disease progresses, the preexisting problems deteriorate, and the patient will lose new skills and abilities. Also, in this stage, the patient starts to lose his independence, which puts stress on the family and caregivers.
Memory problems deteriorate to the degree that involves the older memories and makes the patient unable to recognize his family, relatives, and friends. Language problems become more marked than in the previous stage. The patient forgets the essential words and replaces them with incorrect ones, which impairs the ability to communicate. Also, the patient loses the writing and reading skills progressively in this stage.
Behavior and personality problems increase and become more common. The patient may suffer from:
- Wandering: It represents the main problem for caregivers because they may lose the patient at night without appropriate clothes and because he can’t protect himself.
- Emotional incontinence: It is an emotional disturbance, which, during it, the patient shows sudden, unexpected, and uncontrolled emotions, such as laughing, crying, and aggression with resistance to the caregivers.
Also, the patients in this stage suffer from illusions and delusions, and they may show impulsive behavior. Multiple tasking (tasks that require sequential steps), such as clothing and bathing, becomes difficult for patients in this stage.
The patient also will be unaware of his disease and problems, which increases the stress on the caregiver.
