Is mild frontal lobe atrophy normal at an age of 51? My mum had a brain scan for a stroke and everything came back clear. Her heart is very healthy. She has Type 2 Diabetes but she has this very under control and most doctors are surprised. She also had some high cholesterol issues in the past but this is also under control. The consultant who looked at the scan said she had no stroke issues but on the report, there was some mild frontal lobe atrophy. I did not fully understand and asked if this was abnormal, which he said yes to but he said it was not dementia-related when I asked. He did say that my mum may begin experiencing forgetfulness, etc. Should I be worried and she has never displayed any dementia symptoms, impulsiveness or personality change etc?
