Catastrophic injuries almost always lead to long-term or permanent disabilities. You might have to take medication or use ambulatory aids for the rest of your life. You could require therapy, including physical, occupational, or cognitive and other psychological therapies.
If your injuries affect your ability to move, you could require modifications made to your home and/or vehicle, or you could require part-time or full-time care. That care could be someone who has to quit work to stay home and take care of you, or it could be part-time or full-time professional care.
