In fact, a 2017 study published in the journal International Psychogeriatrics found that verbal repetition occurred in over 47 percent of dementia patients.
"Verbal repetition was more frequent in individuals with mild dementia compared to those with moderate and severe dementia and in those with Alzheimer's disease versus other dementias," the researchers wrote.
"Overall, verbal repetition was the most common of the 60 possible symptoms reported as a target for monitoring, in 807 individuals.".
If you notice signs of echolalia in yourself or someone else, don't panic: Alzheimer's is not the only possible explanation for this symptom.It's important to see a doctor who can help to determine whether verbal repetition is related to dementia.
