One in three Israelis have described symptoms consistent with post-traumatic stress disorder (PTSD) following the October 7 attacks, according to a new study carried out by researchers at Achva Academic College, Haifa University and Columbia University, Al Jazeera reports.

It surveyed 420 Israelis aged 18 and above about their level of exposure to the attacks and the subsequent war in Gaza, stated a Haaretz newspaper report.

Among the respondents, 34 per cent had symptoms consistent with PTSD, with the portion exceeding 50 per cent for those who experienced the attacks directly or lost someone close to them, the report said.
