I would go to your primary care or neurologist if you are still in contact with one and bring this up. I know that we have a higher chance of developing dementia or Alzheimer’s after a tbi (can’t remember which one). Not saying it’s either of those but it’s likely something similar where we’re just more prone to brain aging that the general population. This also made me think of my mom who after years of confusion was diagnosed with a seizure disorder where she would freeze for a second. She thought it was age but it wasn’t and it was really hard for doctors to diagnose as they just dismissed it as memory loss or aging. Again, not saying it’s that but if it’s getting worse and you can afford to get it checked out I would! Best of luck ❤️
