Alzheimer’s disease begins slowly. At first, the only symptom may be mild forgetfulness. In this stage, people may have trouble remembering recent events, activities, or the names of familiar people or things. They may not be able to solve simple math problems. Such difficulties may be a bother, but usually they are not serious enough to cause alarm.
However, as the disease goes on, symptoms are more easily noticed and become serious enough to cause people with Alzheimer’s disease or their family members to seek medical help.
For example, people in the middle stages of Alzheimer’s disease may forget how to do simple tasks, like brushing their teeth or combing their hair. They can no longer think clearly. They begin to have problems speaking, under-standing, reading, or writing. Later on, people with Alzheimer’s disease may become anxious or aggressive, or wander away from home. Eventually, patients need total care.
Many different medical conditions may cause symptoms that seem like Alzheimer’s disease, but are not. Some of these medical conditions may be treatable. Reversible conditions can be caused by a high fever, dehydration, vitamin deficiency and poor nutrition, bad reactions to medicines, problems with the thyroid gland, or a minor head in_jury. Medical conditions like these can be serious and should be treated by a doctor as soon as possible.
