Welcome to the forum. It's great to hear that Mum has been given the all clear but I'm really sorry to read that she is struggling with this side effect of her treatment. I'm sure that it is frustrating and upsetting for you all.
We have some information on our website about Chemo brain including some tips for practical tips for coping. If you think it would be helpful to talk to our team of nurses then please do give them a call. They are available Monday to Friday 9am-5pm on 0808 800 4040 (free to call from a UK landline).
Sending you our best wishes, Jenn Cancer Chat modertor
