I am age 67, neighbors in 20s, I was physically attacked by them. Does this constitute elder abuse?

Was physically atttacked by neighbors (husb & wife) when wife struck me with fists, we fell to ground, husb jerked me up off of wife and slammed me to ground then called police, while on phone wife again hit me in head with fist, I went to hosp was diagnosed with concussion. Police arrived, took statements and no further action. This happened on my rental property, I informed prop mgr, no action taken.. Happened 1+ year ago and neighbors are severely harassing me again when for the second time, have and currently are using their vehicle to block me in carport parking space. Last time I reported to police after being blocked in for 4 days and police stated that they could not assist because it was private property, need to contact prop mgr. Contacted prop mgr who failed to resolve. What may be my legal options? I am a US Army veteran, I receive subsidized housing assistance but I'm very afraid to notify my housing authority without knowing what my legal options may be!
