My husband has always had slight problems in use of language, both comprehension of and expression of complex concepts. However non verbally he has been a top performer, very good at maths ,and related things. He has held a top job in the oil business and still trains people in sales techniques which does require good expression in a structured context. Recently in the home and personal context he seems to have increasing problems with finding words, using the right word, understanding a complex sentence and memory of what he has been told. He says he has no problems outside of the home. But I have observed he can't relate a story or give a good account of an event. These changes are subtle and I wonder if it's just ageing and life course events as he may be made, happily, redundant soon. He is 62. He does not seem depressed but is often very grumpy. Although he's often been this way over the years. Should I worry
