People having Alzheimer’s might lose track of time, seasons, or even the passage of date. They suffer from difficulty in understanding a certain thing if it is not occurring spontaneously. The agitation and confusion is another common symptom among Alzheimer’s patients. At times the patients might forget how they got somewhere or where they are present. However, the severity of dementia ranges from a milder stage, where it is just the initiation of impaired functioning to the chronic stage, where the person absolutely depends on others for performing daily life activities.
