OBJECTIVE: The study was conducted to systematically investigate previous anecdotal reports of memory decline during pregnancy. STUDY DESIGN: We used a longitudinal design to investigate memory in women throughout pregnancy and in the postpartum period. Closely matched, nonpregnant women were similarly studied at equivalent intervals. We also assessed degree of depression and anxiety. RESULTS: There was a significant time-by-group interaction (P < .01) for both immediate and delayed recall of paragraph length material. Contrasts showed a significant decline in memory for the pregnant group from the second to the third trimester (P < .01). No significant changes in memory were noted for the control group. The pregnant women scored higher on both depression and anxiety scales; however, somatic rather than cognitive items accounted for the elevated scores. Fluctuations in mood and memory did not coincide. CONCLUSION: There is a pregnancy-related decline in memory, which is limited to the third trimester. The decline is not attributable to depression, anxiety, sleep deprivation, or other physical changes associated with pregnancy.

Memory in pregnancy. II: Implicit, incidental, explicit, semantic, short-term, working and prospective memory in primigravid, multigravid and postpartum women.

This study, using an information processing model of memory, made a detailed examination of the possible locus (loci) of any memory change in gravid and postpartum women using a battery of seven objective memory tests: implicit, incidental, explicit, semantic, short-term, working, and prospective memory. In addition, links were sought both between (a) self-reported data on sleep, health, and memory performance, and (b) these variables and objective memory performance. Five groups of women were tested (n = 22/23 per group), (1) primigravid, (2) multigravid, (3) postpartum, (4) non-pregnant parents with children, and (5) never been pregnant, on self-report and objective memory tests. The gravid and postpartum groups reported significantly more everyday forgetting than the non-pregnant groups but on the objective tests performed no differently from the non-pregnant groups on all tests. Sleep loss was a significant predictor of reported memory change, but not of any memory test performance, and may contribute to a perceived memory change. Pregnant women and new mothers generally should be confident of performing to their normal cognitive capabilities, but may be more affected than usual by a high cognitive load.

Memory in pregnancy. I: Subjective experiences and objective assessment of implicit, explicit and working memory in primigravid and primiparous women.

J Psychosom Obstet Gynaecol 1999 Jun;20(2):80-7 (ISSN: 0167-482X)

This study investigated the belief held by over 50% of parous women that they are more forgetful during pregnancy and postpartum relative to other times. Comparisons were made between both the reported and objective memory performances of three groups of women (n = 20 per group), (1) primigravid, (2) primiparous (baby younger than 12 months), and (3) never been pregnant, matched on age and education levels. Participants completed a questionnaire on demographic, health, and sleep details, the Inventory of Memory Experiences, and tests of implicit, explicit, and working memory. The groups did not differ on self-rated levels of physical or emotional health, or anxiety level. The primigravid and primiparous groups reported overall poorer memory performance since pregnancy relative to controls. The primigravid group also reported significantly more sleep disruption, with this being a significant predictor of reported memory change. On the objective tests, there were no differences between groups on the implicit and explicit memory tests, but the primigravid and primiparous groups scored significantly lower on a test of working memory. Self-reports of memory change during pregnancy and postpartum may be related to life changes, such as sleep change, and may reflect changed perceptions rather than objective changes.

a couple?? of years ago I remember a patient telling me about an article (NYtimes???)about pregnancy and brain changes.... does this sound even vaguely familiar...it supposedly talked about why pregnant women tend to be forgetful and that the brain actually shrinks...any ideas?
