Alzheimer’s disease is the most common type of dementia. Dementia is a disease of the brain. We use “stages” to describe how severe the disease is. The stages explain how the person’s brain is working which helps the caregiver know what to expect. This can help you plan care for your loved one. The stages overlap and no two people progress through the stages at the same rate or with the same symptoms.
Stage 1: No Impairment (Normal Function)
The person’s memory and thinking seems to be normal. Doctors cannot find symptoms of Alzheimer’s disease during an exam.
Mild Alzheimer’s Disease: Early Stages
Stage 2: Very Mild
The person notices changes with their memory, such as not knowing where they put their keys. These may be normal changes from aging or early signs of Alzheimer’s disease. No symptoms can be found during a medical exam.
Stage 3: Mild
Friends, family or co-workers may begin to see memory problems. The memory issue shows up in daily life or work. A doctor may see problems with thinking or memory during an exam. These problems include:
Problems coming up with the right word or names of people they know.
Trouble remembering new names.
Losing or misplacing items.
Struggling to organize or plan.
