May 2004: Hardy, three days after the attack, on patrol near Tikrit for an external security mission. Hardy's TBI went undiagnosed for two years. TBI symptoms include a range of memory problems, sleep disorders, emotional difficulties, headaches and irritability. Of the 1.5 million Americans who have served in either Iraq or Afghanistan, or both, potentially 150,000 come home with TBI symptoms.
