This is a strange query.  My first impulse is to say that if you want
to know what relevance LTP has for medicine and health you have no
business studying LTP.

My impression over many years that people (and government agencies)
throwing time and money at "practical questions" almost never discover
anything relevant either to basic science OR to the practical question.

LTP is an electrophysiological phenomenon which is explored intensively
at molecular levels because some think it is a model for very basic
processes underlying memory formation.  Do you think memory formation
is relevant to health isssues?

A synapse is a site/structure where one neuron communicates to another
via a chemical messenger.  Without synapses, our brains wouldn't work. 
Maybe this would be a health issue.

There is no end to the list of physiological phenomena which have
implications for medicine and health.  Why pick on LTP?

Before you ask for "the hottest ideas floating around in the
literature", ask yourself what you are interested in, and at what
level.  READ some of those articles about LTP.  Ask yourself if this is
really what you are interested in.

If you are really interested in "health related issues", perhaps you'd
do better with "public health" publications, etc.

For me, personally, a hot idea is that NO can facilitate or block LTP,
depending on when/where/how it is produced...
