Pseudotumor cerebri is primarily seen in obese women of childbearing age, and although the condition affects only 1 in 100,000 people in the United States, the rate for obese women between the ages of 20 and 44 is about 19 per 100,000.

In areas with higher levels of obesity, however, pseudotumor cerebri is being seen more frequently.

In Mississippi, called the most overweight state in the nation because a quarter of its population is considered obese by BMI criteria, the incidence of pseudotumor cerebri in the overall population is double, at 2 per 100,000, and among obese women aged 20-44, the rate is about 25 per 100,000.
