I disagree with Ali B. I do not think she should put herself in a noisy or bright or flashing environment, even if she thinks she is having a good day. When she has be able to be symptoms free in normal environments, she can then try to introduce some more stimulating environments. The challenge of trying to second guess the brain's tolerance level is a losing game.

Like Ali said, she should pay attention to the times when she overloads and try to think back to the possible triggers. Family can often help her with this by noticing the look in her eyes. The eyes are often the first sign of overload. That spacey look or repeating herself or not understanding someone are all signs of overload.

At her age, recovery will take far more care to avoid triggers. The older a brain gets, the more struggle it has at recovery.

My best to you both.
