The Dementors

Can anyone please help??
My dear other half has been
re-reading PoA and has come up
against a major problem which may be
spoiling his enjoyment of it :(
Namely, the Dementors (no, not their
existence, that's upsetting him,
that's pretty universal...) - why do
they affect Harry so badly that he
passes out every time they come near?
They upset and frighten everyone, but
it's only Harry who is so disturbed.
I'm sure that this must have been
discussed in the past but I couldn't
find anything in the search and my
crappy TV email makes searching v.
difficult - so if anyone can point me
to the past posts,   I'd be v
grateful...
