My husband had an stroke 6 years ago in his thalamus which caused him to be confused, short term memory loss, some long term memory loss,etc. The good news is that he regained almost all of his functioning, but some small short term memory issues. 3 weeks ago he worked in the yard in 100 degree temps for several hours. The next day he woke up with the same symptoms as the stroke 6 years ago and we assumed he had another stroke. The MRI, CTScan shows no new stroke, but his symptoms continue and he doesn't seem to be getting much better. He has lost his job due to the memory loss issues. Any thoughts on what could have happened? We are seeing a neuropsychologist.
