Dementia is usually associated with memory loss and problems with thinking, but some warning signs may appear much earlier. According to the report, noncognitive symptoms can begin years — and in some cases even decades — before a formal diagnosis is made.
The story highlights six possible early symptoms that may show up well before the more familiar cognitive changes. Among the examples mentioned are shifts in sleep patterns and changes in walking, suggesting that dementia-related changes are not always limited to memory and reasoning in the beginning.
Alzheimer's disease, the most common form of dementia, is often recognized only after noticeable thinking problems develop. But growing attention on earlier physical and behavioral changes may help broaden understanding of how the condition develops over time.
The report underscores an important point for patients and families: dementia can have a long early phase in which symptoms are subtle and may not seem connected to brain health. That makes awareness of less obvious changes especially important when considering the full picture of symptoms that can come before diagnosis.
