initial value problem

I have an initial value problem (ordinary differential equation) with 
advanced & retarded arguments that arises in a polymerization problem:

u''[x] + a(x) u'[x] +b(x) u[x] + c(x)f(u[x+1], u[x], u[x-1]) == 0
   c1 u[0} + c2 u'[0] == 0
   u[Infinity] = 0

Is it possible to program such equations in Mma?
