Could a fall on my head be the reason for my stutter?

Could a fall on my head be the reason for my stutter? When I was 2 years old, I had a fall on my head where I fell and directly landed on the backside of my head. The fall was quite severe as my pupils were in my socket, I turned blue, vomited multiple times and utimately spent 4-5 days in ICU. According to the neurologist I had no permanent brain injury and I carried on with life as usual. Right now I am 27 years old and was thinking that in my family no one stutters then from where do I get the speech problem? Maybe this fall could be reason or not? Need y'll insights Thanks
