(M-W let me down this time)

The etymology of nostomania combines the Greek word  νόστος (nóstos), meaning "a return home", with the suffix -mania (from the Greek mania), meaning "madness" or "excessive enthusiasm.   Thus, nostomania literally translates to a "madness for a return home," describing an overwhelming desire to return to one's home or familiar places.  Nostomania is an extreme form of homesickness or a passionate longing for the familiar, similar to how "nostalgia" (from nostos and algos, meaning "pain") signifies a longing for the past. 

According to the Oxford English Dictionary (OED), the earliest known use of the word nostomania in English was in 1835 in the Cyclopaedia of Practical Medicine.
