For care assessment, what is considered capital, what is income? Is there a difference in the way they can be used once going into care?

My mother is currently under assessment with a view to going into long term care. She has a limited amount of liquid assets but does own her own home which will be sold and the proceeds used to fund her care. Whilst she has funds she will be pay for her own care until she reaches £23.500 threshold. Until this time she will also continue to receive her old age pension. I understand she cannot give away too much of her money from the house sale as this will be considered asset stripping and a later penalty can be imposed to recover this. I believe the money from the house is considered as capital. Does the same apply to her pension money, or can she spend this as she wishes?
