Hello Mark, have you tried asking your mums neuro or GP for an assessment to be carried out in the house? I told my neuro about my difficulties and a home visit was arranged for an assessment. As a direct result of this I was provided with a number of adaptations to help me with my daily living.
I'm sure that this would be the way forward and I'm pretty sure also that if there are adaptations required to the property you can apply for a grant to assist with the costs. It might help you if you have a look at www.directgov.org
. I hope this helps.
