Short term memory loss

[PJH44]

My father (age 80) woke up one morning confused and suffering short term memory loss. He had an EEG and MRI and both showed nothing abnormal going on. I speak with him on the phone everyday and I cannot tell anything different, but my mom says every so often he asks her a question she's already answered for him a couple times that day. The doctors put him on anti-siezure medicine, but they say there is no evidence he actually suffered any type of seizure. We would just like some answers as to what may be causing this. The neurologist does not seem very concerned, but we have a hard time believing doctors haven't seen something like  this before that has come on very suddenly.
Anyone had any experience with something like this before?
Thanks for any help.

Would MCI happen so suddently?

[Abhijeet Deshmukh, MD]

Hello.

At this age, the chances of Dementia are high. This could be the beginning of it. The initial stage is called Mild Cognitive Impairment (MCI).

Anti-seizure medicine will not work. You need to discuss the MCI issue with his Neurologist. There are some good new medicines that have come up recently, to stop the damage.

Hope this helps.
