If it weren’t for church services and semi-regular in-office work, my in-person contact would be just wife and kids.
I believe the Japanese have a near analogous term for this: Hikikomori.

So what’s your point?
Hikikomori is a level or two beyond what most westerners would think of when imagining an extremely introverted or reclusive person. The condition is more akin to PTSD stemming from severe mental/social trauma.
For further context, the etymology of hikikomori is to "hiku" (literally "pull", contextually in this case to "pull back" from daily life) and "komoru" (to "shelter up", in this case most likely sheltering in your bedroom or mancave or similar safe space).
What makes the news and what makes it to the Western media are the most extreme cases.
The actual development to the extreme (or not) can be quite gradual.
