Mouse maternal odontogenic infection with Porphyromonas gingivalis induces cognitive decline in offspring.

The offspring of -infected mothers have reduced cognitive function. Neurodegeneration/neuroinflammation in the hippocampus and amygdala may be caused by infection, which is maternally transmitted. The importance of eliminating maternal -odontogenic infection before or during gestation in maintenance healthy brain function in offspring should be addressed in near future.
