Typical Effects


Brain Injury EffectsBrain injury can affect a survivor’s physical, cognitive, and psycho-social functioning.  According to Make the Connection, the effects of brain injury on survivors “sometimes cause other difficulties such as sleeping problems, depression, and anxiety.” The following list of typical effects, does not describe every possible situation nor does it apply to every survivor.

  1. Hi SCOTT there is at least one more item that comes to mind and there may be others too as I am writing this reply..
    The first one is difficulty managing or following through on goals. then the next one is appropriate money managing..
    being easily taken advantage of, because one often lacks the ability to be able to discern or differentiate people’s true intentions, then there are some people who get addicted to stuff like pot drugs, porn, have low self esteem or self worth issues…

    I am sure there are many more but they are as different for each individuals as are their unique TBI’S.

    The one common thread though is that they all seem to originate from the individual loss caused by the TBI. and that they all seem to stem from their individual loss of their ability to receive love or know how to fill the void that must be filled up whenever something changes in the TBI’S life. I trust that this is helpful LOVE FF

    1. Fantastic Frank, I appreciate your comments, and I will add them to the post — giving you credit of course. I am working on a different post right now, but as soon as I reach a good stopping point, I will update the list. Thank you.
