The Health Service Executive (HSE) says it received 2,437 reports of alleged elder abuse last year, which is a marginal decline on 2012.
However, this is a 30% increase in the number of referrals since 2008.
Psychological abuse was the most common type of abuse reported at 33%, followed by financial abuse (26%), neglect (21%) and physical abuse (14%).
Most cases were brought to the attention of the HSE by public health nurses.
Two-thirds of the alleged victims were female, while younger men (65-74 years) are more likely to be referred. 55% of females referred are in the over 80 age category.
The HSE says most alleged abuse is perpetrated by a family member - most likely a son or daughter; 45%, partner/husband/wife; 19% and other relative in 15% of cases.
Commenting on the figures, chair of the National Elder Abuse Steering Committee Frank Murphy said "There is strong documentary evidence that a certain proportion of older people are at risk of being abused and it is vital that older people are protected from harm in both the community and in residential settings."
"We would encourage anyone who has a concern about abuse of an older person to contact their GP, public health nurse or any healthcare worker."
If a person is being abused, or if someone is concerned about abuse or suspect that someone they know is being abused, they can contact the HSE Information Line on 1850 24 1850. Alternatively, they can contact a health professional such as GP, public health nurse or social worker.
