Table 3. Accompanying symptoms, co-morbid conditions, and family history.

Survey respondents were asked if their SEES symptoms were associated with migraines, headaches, and light sensitivity. Respondents were also asked if they had migraines or headaches independent of SEES symptoms. Respondents were asked about mental health conditions, other disturbances of visual perception, and a family history of migraine or SEES. Percentages are expressed as a fraction of the number of participants who responded to the question.
