"A statistically significant increase was seen in the frequency of symptoms among women compared with men; and ... the most frequently reported symptoms were neurological (i.e., headache, memory difficulty, slurred speech, spaciness, lightheadedness, dizziness, weakness, coordination problems, and changes in vision), state of well-being (excessive fatigue, bloating, rash, discomfort, and muscle spasms), and ophthalmic and upper/lower respiratory (nasal symptoms, sinus discomfort, coughing, watery eyes, throat discomfort, weak voice, chest tightness, and wheezing)."
