Hi all, My husband of almost 40 years has always been absent minded and clumsy as a result. He has always had a phenomenal intellect and is a true lateral thinker. He is a gifted engineer. Recently he spills, drops, loses thing constantly and is becoming angrier and angrier about it. His frustration threshold is less and less. He started to "go downhill" after retiring early at 57 but it has become noticeably more of a problem since his hernia op 2 years ago. Most days are good but some days he cannot remember anything from one minute to the next. He has always been a hoarder but he is now totally unable to organise his possessions and our house is becoming unmanageable. I still work but will retire in 2016. I am not as tolerant and understanding as maybe I should be but it's hard seeing the man I have always loved and looked up to become randomly incompetant. Is this the start of dementia or should we be looking at another cause for his behaviour? Maybe depression or boredom? He is 61 and there is no history of dementia in his family. They are very long-lived - generally into their 90s.
