Well my dad had had at least a year of very difficult behaviour by the time the meeting was help. In brief, he did things that put him ,and potentially others at risk, such as entering people's property, leaving his home early in the morning and getting lost, taking other people's property, taking stuff in shops (he got barred from Poundland!) and even eating other people's food in cafes (I'm leaving some stuff out to protect his dignity).
There are some buzzwords that play well in CHC assessments. They are intensity, unpredictability, complexity (so if the behaviour can be described in any of these ways so much the better).
Also quote back at them a key point of the Govt's paper on CHC "A met need is still a need". Just because you are running around averting crises and making sure your mum is safe, does not mean she does not have a need that the CCG has a responsibility to address.
It's sad we have to resort to cynical bureaucratic game playing, but if that's what it takes...
