Forgetting where you kept your keys, walking into a room and suddenly losing track of why you went there, or struggling to recall a familiar name can become surprisingly common during pregnancy. This experience is often referred to as “momnesia” or “pregnancy brain.”
While these moments can be frustrating, forgetfulness during pregnancy is generally considered common. It is estimated that up to 70 per cent of women experience some form of memory or concentration difficulty while expecting.
What Is Momnesia During Pregnancy?
“Momnesia” is a commonly used term for temporary forgetfulness, difficulty concentrating and a feeling of mental fog that can occur during pregnancy and the early months of motherhood. It is important to note that momnesia is not a medical diagnosis. Instead, the term is used informally to describe certain changes in memory and cognitive functioning.
Some common experiences include forgetting medical appointments or everyday tasks, losing track of where household items were placed, finding it difficult to concentrate on a thought, and struggling to recall familiar names or words. Some women may also feel mentally overwhelmed when dealing with complicated information.
Why Does Pregnancy Cause Forgetfulness?
Several physical and emotional changes associated with pregnancy can contribute to feelings of forgetfulness and reduced concentration.
Hormonal Changes
Pregnancy brings major hormonal fluctuations, particularly involving estrogen and progesterone. These changes can affect brain pathways associated with concentration and memory formation. Research has indicated that increased estrogen levels may temporarily influence memory-processing functions in the hippocampus.
Poor or Interrupted Sleep
Sleep can become difficult during pregnancy because of body discomfort, frequent nighttime trips to the bathroom and digestive problems. Insufficient or interrupted sleep can affect short-term memory, concentration and thinking abilities.
Stress and Emotional Changes
Pregnancy involves significant physical and emotional adjustments. Increased stress and changes in emotions may affect cognitive functioning. Higher levels of stress hormones such as cortisol can also influence working and spatial memory.
Increased Mental Workload
Pregnancy involves keeping track of prenatal appointments, health-related instructions, preparations for the baby and numerous other responsibilities. Managing all of these tasks can place a considerable mental load on an expecting mother.
Fatigue and Physical Discomfort
Morning sickness, nausea, anaemia, body aches and general fatigue can leave women with less energy. This physical exhaustion may also make it harder to concentrate and remember things.
7 Simple Ways To Manage Pregnancy Forgetfulness
There are several simple strategies that can make everyday tasks easier when pregnancy-related forgetfulness becomes noticeable.
Use calendars and reminders: Digital calendars, alarms and phone reminders can help keep track of appointments and important tasks without relying entirely on memory.
Keep important items in fixed places: Create specific spots for frequently used belongings such as keys, glasses, wallets and phone chargers.
Break large tasks into smaller ones: Instead of trying to remember everything at once, make a short list containing three or four important tasks for the day.
Prioritise sleep and rest: Getting sufficient rest can support concentration. An afternoon nap and a consistent bedtime routine may also help.
Stay hydrated and eat regularly: Drinking enough water and maintaining regular meals can help support normal brain function and energy levels.
Avoid multitasking: Focusing on one task at a time can make it easier to stay organised and remember what needs to be done.
Give yourself extra time: Leaving some additional time between activities can reduce rushing and unnecessary stress.
Is Momnesia Normal During Pregnancy?
Mild forgetfulness during pregnancy can be a normal experience. According to the National Institutes of Health, cognitive experiences can vary considerably from one woman to another. While some women notice brain fog or memory difficulties, others may experience little or no change.
Occasional forgetfulness does not mean that the brain has suffered permanent impairment. However, the severity and frequency of these experiences can differ between individuals.
When Should You Consult A Doctor?
Although occasional pregnancy-related forgetfulness is generally not considered dangerous, certain changes should be discussed with an obstetrician-gynaecologist or another healthcare professional.
Medical advice may be appropriate if memory problems appear suddenly, become significantly worse or begin interfering with everyday activities and overall well-being. It is also important to seek help if brain fog occurs alongside unusual mood changes, depression or anxiety.
Memory problems accompanied by severe tiredness, dizziness or other symptoms may also require evaluation for conditions such as thyroid dysfunction or nutritional problems, including anaemia.
Conclusion
“Momnesia” describes the temporary forgetfulness and mental fog that some women experience during pregnancy and the early months of motherhood. Hormonal fluctuations, disrupted sleep, emotional changes, increased mental workload, fatigue and physical discomfort can all contribute to these experiences.
For many women, occasional forgetfulness is a normal part of the changes that accompany pregnancy. Simple strategies such as using reminders, getting adequate rest, staying organised and avoiding multitasking can make daily life easier.
