Exposure to social stress not only impairs a mother's ability to care for her children but may also negatively impact her daughter's ability to provide maternal care to future offspring.
A new study has revealed this. Researchers at the Cummings School of Veterinary Medicine at Tufts University conducted a transgenerational study with female rats, examining the behavioural and physiological changes in mothers exposed to chronic social stress early in life as a model for postpartum depression and anxiety.
Depression Symptom Evaluation
Depression occurs due to alterations in the levels of neurotransmitters in the brain.

A different male rat was placed in the cage of the first-generation mothers and their newly born pups for an hour a day for 15 days. Consistent with previous research, the lactating mother rats responded to the stress of the intruder with depressed maternal care, impaired lactation, and increased anxiety. The pups of these mothers were also exposed to the conflict between their mothers and the male intruders.
After reaching maturation, second-generation females were mated and compared to a control group where neither the mother nor the pups had been exposed to a male intruder.

Depression is a common disorder and many worldwide suffer from depression. Early recognition of symptoms and signs of depression can help in taking a holistic approach to the management of depression.
The second generation mothers that experienced the early life stress also displayed depressed maternal care, impaired lactation, and increased anxiety. There were also changes to hormone levels: an increase in the stress hormone corticosterone, and decreases in oxytocin, prolactin and estradiol.
C. Nephew, Ph.D., principal investigator of the study, said that the endocrine and behavioral data are consistent with what has been reported in studies of depressed human mothers.
The study was published in journal Hormones and Behaviour.
