A new study finds allergies make a person prone to worsening mood, cognition and quality of life. Also, the study finds a large peak in pollen particles floating in the air occurs in the spring with a smaller peak in the fall. This coincides with a worldwide spike in suicides every spring and a lower peak in the fall.
The study presented at the American Psychiatric Association's annual meeting is believed to be the first study to link allergies with depression.
Authors say treating allergies could prevent patients from having a depressive episode during high-pollen season.
