Mickey had said at some point he had serious insomnia and was prone to missing entire days of sleep... I knew young people that missed sleep chronically, some due to health problems. They looked like death, were mentally fragile and you couldn't expect much of them.. lack of sleep will mimic many things in itself... if he's not getting adequate sleep in conjunction with other issues (like CTE), jet lag or just not being able to get quality sleep period. Imo, he needed his own bedroom with his sleep condition if he was going to make it through. Not even considering any withdrawal from drugs or alcohol. So much can explain his demeanor so I don't think we can assume very much... though I think if he had significant dementia, he would not be able to cope in the house for very long at all.
