Family members are often the first to notice the early signs of Alzheimer's: problems with memory, thinking, and language. Symptoms of early-stage AD vary from person to person, and they may seem more apparent at certain times. That is why it is important to pay attention to possible problems and keep track of how often and how regularly they occur. Any pattern should be brought to a doctor's attention. The chances of treating any disease or disorder are far better if it is detected and diagnosed in its early stages.
