The 7 Stages of Alzheimer’s Disease: What to Expect

Alzheimer’s doesn’t happen overnight—it progresses through seven distinct stages, each affecting memory, cognition, and daily life in different ways. At Discern, we provide science-backed cognitive testing to assist in early detection and management of cognitive decline. Understanding these stages can help families and caregivers prepare for what’s ahead.

Stage 1: No Symptoms (Preclinical Alzheimer’s)

There are no obvious signs in this stage, but changes in the brain have already begun. Early detection through cognitive testing and AI-powered analysis can help identify risks before symptoms appear.

Stage 2: Very Mild Cognitive Decline

Forgetfulness begins, but it’s often mistaken for normal aging. This could include misplacing items or forgetting names, though it doesn’t impact daily life significantly.

Stage 3: Mild Cognitive Decline

Memory lapses become more noticeable. Trouble remembering recent events, difficulty concentrating, and challenges in work or social settings may arise. This is when doctors can often diagnose mild cognitive impairment (MCI).

Stage 4: Moderate Cognitive Decline (Early-Stage Alzheimer’s)

At this point, Alzheimer’s is officially diagnosed. Individuals struggle with managing finances, remembering personal history, and organizing daily tasks. Personality changes may also emerge.

Stage 5: Moderately Severe Cognitive Decline

Assistance with daily activities becomes necessary. Individuals may forget important details like their own address or phone number and experience confusion about time and place.

Stage 6: Severe Cognitive Decline

Memory loss worsens significantly. Individuals may fail to recognize loved ones, experience difficulty speaking, and require help with basic tasks like dressing and eating. Behavioral changes, including anxiety or aggression, are common.

Stage 7: Very Severe Cognitive Decline (Late-Stage Alzheimer’s)

At this final stage, individuals lose the ability to communicate, walk, and control movements. Around-the-clock care is essential.

Why Early Detection Matters

Recognizing the stages early allows for better planning, treatment, and support. Discern’s advanced cognitive testing tools help detect Alzheimer’s sooner, making it easier for families to take proactive steps.
