The Pentagon has updated the total number of troops who were treated with traumatic brain injuries following the January 8 Iranian missile attack on an Iraqi base housing U.S. troops to 64, CNN reported .
After U.S. officials, including President Donald Trump, initially claimed that there were no causalities, the Pentagon has been steadily reporting a higher number of reported injuries. Earlier this week, the Pentagon said that 50 troops were treated for traumatic brain injuries, up from a figure of 34 put out by the Pentagon last week.
It is unknown how soon symptoms from these injuries presented themselves. The CDC says that some traumatic brain injuries "may not be noticed for days or months after the injury, or until the person resumes their everyday life."
The symptoms of traumatic brain injuries include difficulties thinking clearly, headaches, irritability, changes in sleep patterns and changes to vision.
