That is a description of my 3.5 year old when he hasn’t had enough exercise for a day or two and is tired and/or hungry.
I haven’t spent an appreciable amount of time with a kid who is always completely uninterested in stories of any kind. But I can speculatively imagine a variety of possible causes for that: other distracting stimuli, malnutrition, exposure to toxins, disease, congenital brain abnormality, emotional abuse, ...
Do you have some particular kid in mind?
Or if this is an analogy to problem solving: if someone literally can’t manage to attempt any kind of problem no matter how trivial, then “easily give up when I face a hard problem” would not be an accurate description of the situation.
What would you say if they were bored / distracted by everything you read to them, not just the difficult things?
