Study Links Birth Control Shot to Memory Loss

Birth control shot Depo Provera impairs memory, reveals research from Arizona State University.

The ASU study connects medroxyprogesterone acetate (MPA), the hormone active in Depo Provera and many widely used menopausal hormone therapies, to impaired memory in rodents.

Birth Control Patch – How to Use, Advantages and Disadvantages
A birth control patch is a new method of contraception for women for once weekly external application and contains both estrogen and progesterone.

The U.S. Food and Drug Administration originally approved Depo Provera for use in October 1992.

The study used three groups of rats (which received doses at varying ages), plus a control group that did not receive the hormone.

"What we found was pretty shocking - animals that had been given the drug at any point in their life were memory impaired at middle age compared to animals that never had the drug," said Braden.

"We also confirmed that in the subjects that only received the drug when young, the hormone was no longer circulating during memory testing when older, showing it had cleared from the system yet still had effects on brain function," he stated.

Bimonte-Nelson added,"This research shows that even after this hormone is no longer on board, months and months later, resulting effects are impacting the brain and its function."

The study appeared in the journal Psychopharmacology.
