Another concrete verbal sign is substituting incorrect words — saying "stove" when meaning "microwave," for instance. Initially these errors may seem minor or even amusing, but experts caution that over time the substituted words can have no logical connection to the intended meaning at all. Frequent occurrences of this pattern are considered a potential indicator of declining cognitive function that merits professional assessment.
"I know what I want to say, but I can’t find the words" — and what comes next
Two of the more striking verbal warning signs identified by experts involve language that reaches back in time. Some individuals with dementia begin reverting to a native or childhood language they have not used regularly for years. Experts explain that early-learned languages are deeply ingrained in the brain, and that stress or confusion can trigger a return to childhood expressions or dialects. A sudden, unexplained shift toward a long-unused language may indicate that dementia is progressing.
Perhaps the most emotionally charged sign is when a person expresses direct frustration about their own communication difficulties. Experts highlight the phrase "I know what I want to say, but I can’t find the words" as a significant indicator — one that reflects a person’s awareness of their decline even before others around them have fully noticed.
This self-awareness can generate feelings of anxiety, embarrassment, and withdrawal. Experts stress that if a loved one frequently voices distress about their communication struggles, it is important to seek medical advice promptly to explore potential causes and discuss dementia care options. Early detection remains the most effective pathway to better management of the condition, enabling individuals to maintain quality of life and access the right support structures before the window for early intervention closes.
The next step for families who recognize several of these patterns in a loved one is to consult a general practitioner or a specialist in cognitive health for a formal assessment. Questions remain open about how consistently these verbal signs predict a clinical diagnosis of dementia versus other treatable conditions — such as depression, medication side effects, or hearing loss — that can produce similar communication difficulties. Researchers continue to investigate whether early speech-pattern monitoring, including through digital tools, could one day support faster and broader screening for cognitive decline.
