Caretaking is extremely difficult emotionally and stressful and your brother and cousin really went above and beyond their normal roles to offer your uncle care.

Your family was right to feel concerned about the care your uncle would receive, the sick do enjoy at least more complete care.

My step mother suffers from Alzheimer's and my dad was her primary care person for about four years. She didn't seem to have the issues leaving the house your uncle did, but she did have at least one incident. But back to my dad, by the time he finally put her in a home, his health was in decline. His blood pressure was up, as was his cholesterol. And he was just in a perpetually unhappy mood.

It worked out for the best. The care my step mom gets is good enough and my dad isn't stressed out.

There's no shame in letting professionals step in.
