My husband had DVT and ended up in ER with several clots I his lungs. It took awhile for him robe diagnosed so he may have had it and known it for several months prior to being admitted toER room. He s on Coumadin and recovering but he has noticed some minor aphasia and some memory problems. His dr says that the memory and foggy thinking are a result of depression . Does that sound right?? He was defiantly depressed and had some anxiety but his minor speech problems to us seem like he may have lost some brain function . What could have caused these types of problems
