With my dad I definitely have noticed his ocd getting worse. This was quite an early sign. He also started collecting things. He would go to boot fairs and he bought pottery made by the same manufacturer. He was convinced they would be worth a great deal of money in the future although most items would cost him little more than a pound. Hoarding. Tidying up. All part off the ocd I think.
Definitely anger. He has always been quite an argumentative type but his anger is significant. Then there was a softness with others. So perhaps more extremes than in his younger days.
He has always been a very practical person with diy but he started losing the ability to carry out small repairs quite early too.
