It is also necessary to specify that the people with high IQ have more margin for cognitive loss . In addition, the younger the patient is, the faster the disease advances, and the other way around.
Phases of Alzheimer's
Initial stage 1
At the beginning there is a decrease in fatigue resistance in the execution of tasks. However, you can still execute ordinary tasks correctly. It also diminishes its ability to adapt to extraordinary tasks or unforeseen problems. Small forgetting occurs.
The individual can react to all this with denial, fear, withdrawal or anger. You may also experience hypochondria, anxiety or sadness.
