Mental Issues
Another symptom of premenstrual syndrome is the presence of many mental issues. For instance, you would feel more depressed and stressful. Some people would experience difficulty to remember or focus on things at work or study. This problem is caused when the levels of estrogen in the body are reduced. Estrogen plays a key role in controlling the production and distribution of cortisol, a stress hormone. When estrogen amount drops, the cortisol will not be able to affect neurotransmitters in your brain, thus leading to some laps in the memory. [4]
