Public Release: 

Acute kidney injury linked to higher risk of dementia

American Society of Nephrology

Highlights

  • Patients with acute kidney injury had more than a 3-fold higher risk of developing dementia compared with those without acute kidney injury during a median follow-up time of 5.8 years.
  • Results from the study will be presented at ASN Kidney Week 2018 October 23-October 28 at the San Diego Convention Center.

San Diego, CA (October 25, 2018) -- Acute kidney injury (AKI) is linked with a higher risk of developing dementia, according to a study that will be presented at ASN Kidney Week 2018 October 23-October 28 at the San Diego Convention Center.

AKI, an abrupt decline in kidney function, often arises after major surgeries or severe infections, and it is associated with long-term health problems including the development of chronic kidney disease and cardiovascular disease. AKI is also associated with acute neurologic complications, but the long-term consequences of AKI on brain health are unclear.

To study the issue, Jessica Kendrick, MD (University of Colorado School of Medicine) and her colleagues analyzed information on 2082 patients without a prior history of dementia from an integrated health care delivery system in Utah. Patients had a hospital admission between 1999 and 2009.

During a median follow-up time of 5.8 years, 97 patients developed dementia. More patients with AKI developed dementia (7.0% vs. 2.3%), and patients with AKI had more than a 3-fold higher risk of developing dementia compared with those without AKI.

"AKI, even with complete renal recovery, is associated with an increased risk of dementia," said Dr. Kendrick. "Further studies are needed to determine the long-term cognitive consequences of AKI."

Study: "Acute Kidney Injury is Associated with an Increased Risk of Dementia"

ASN Kidney Week 2018, the largest nephrology meeting of its kind, will provide a forum for more than 13,000 professionals to discuss the latest findings in kidney health research and engage in educational sessions related to advances in the care of patients with kidney and related disorders. Kidney Week 2018 will take place October 23 - October 28 at the San Diego Convention Center.  

Since 1966, ASN has been leading the fight to prevent, treat, and cure kidney diseases throughout the world by educating health professionals and scientists, advancing research and innovation, communicating new knowledge, and advocating for the highest quality care for patients. ASN has more than 20,000 members representing 131 countries. For more information, please visit http://www.asn-online.org.
