My husband experienced a traumatic injury at work 18 months ago. He was hit in the back by a heavy crane load. Broken collar bone, 5 ribs and scapula. Tests never indicated brain injury but about a year ago, I noticed memory loss, behavior not normal for him, lying, fatigue. He finally admitted he thinks there s something wrong. Three months ago he had a complete cardiac exam with stress test and ultrasound passed with no problems. What kind of doctor do we make an appointment with? His PCP told us a year ago there was no indication of memory loss.
