Extreme Amnesia
This man has a memory of between 7 and 30 seconds and recognizes nothing but his wife. Because he has no awareness of things that have happened in the past he is constantly operating under the assumption that he has just awoken from a period of unconsciousness and hasn’t had a single thought in 20 years.
Also, every time he sees his wife he thinks it’s the first time he’s seen her in years.
