It's only a matter of time before he attacks you again. Maybe next time it will be with a knife or some other weapon.
How can you tell that from the OP? Is there a specific condition that leads to this behavior?
I've heard of things like Huntington's Disease and certain types of traumatic brain injury leading to uncharacteristic episodes of extreme violence sometimes accompanied by nausea.
The detail of what he said before initiating the attack (“I’m going to hit you. What will you do if I hit you? Will you hit me back? Will you hit me like this?”) are disturbing because they seem to suggest self-awareness, and deliberation. This would seem like a choice, perhaps driven by a very strong compulsion. What can cause compulsive violence? Can one be certain that it's "only a matter of time before he attacks again?"
I learned about some of these behavioral issues in an intro to neurobiology course I took last year, but violent behavior was not the focus of that class so those little bits of information came in tangentially while were looking at things like the different effects of spinal lesions in different locations, or damage to particular regions of the cortex or cerebellum.
Hopefully, NathansMommy will get the answers she needs from a professional with deep experience in this area.
