Researchers examine a group of 18 Swedish citizens who survived a brutal gas attack in 1988. Then, war materials were used in Kurdish Halabja in Northern Iraq. About 5,000 people were killed.
The results of the study show that the group exposed to mustard gas had a significantly lower quality of life than the control group. Survivors of the Halabja gas attack also had more severe depressive symptoms.
People exposed to mustard gas may need early detection of a mental disorder and additional support to improve their quality of life, the scientists said.
