LOS ANGELES, Aug. 23 (UPI) — U.S. experts on Holocaust survivors say people who lived through the era genocide have a harder time coming to terms with the memories as they age.

Chaya Berci, executive director of nursing at the Los Angeles Jewish Home for the Aging, which houses 63 Holocaust survivors, says some survivors succumb to dementia and believe they are back in Nazi Germany, the Los Angeles Times reported Thursday.

Esther Kane Meyers, daughter of Holocaust survivor and former Jewish Home resident Rachel Kane, said her mother often thought she was seeing Nazis.
