When it comes to Alzheimer's disease, the initial stages can be difficult to recognize. People in the early stages of Alzheimer's may still be able to function independently, driving, working, and participating in social activities. However, they may start to experience memory lapses such as forgetting familiar words or the location of everyday objects. Additionally, they may experience serious mood and behavior changes, as well as confusion about time, place, and life events.
These symptoms may not be easily noticed since the person in the early stages of Alzheimer's retains many of their abilities and may not need or seek assistance. Nevertheless, they may start to have problems completing tasks that they used to do well. When Alzheimer's disease occurs in a person younger than 65, it is known as early-onset Alzheimer's disease. Early-onset Alzheimer's disease can affect people between the ages of 30 and 40.
For most people with early-onset Alzheimer's disease, the symptoms are very similar to those of other forms of Alzheimer's disease. The most common signs include memory loss, difficulty completing familiar tasks, confusion with time and place, and changes in mood and behavior.
