In particular, linguistic functions which are controlled primarily by the brain can be radically impaired if trauma affects the related regions.
Known as aphasia or dysphasia, the loss of fluid language skills is correlated to certain types of brain injury.
Considering that success in the modern world is so often dependent upon a person's ability to communicate clearly and effectively with their coworkers and supervisors, any detriment to language skills that comes from negligence-based injuries is extremely serious.
Aphasia may entail a partial or a complete impairment of some or all of an individual's linguistic abilities.
The inability to speak, pronounce words, read, write, or comprehend language spoken or written by others can interfere dramatically with one's personal and professional interactions.
Moreover, the resulting frustration and sense of isolation can cause intense and prolonged emotional distress.
For an individual whose livelihood is closely entwined with his or her ability to speak clearly and persuasively -- a salesperson, for example -- aphasia acquired due to a traumatic brain injury can permanently compromise the prospects of employment and income, making it difficult to live independently.
There are many subtleties separating different forms of aphasia and the nature and severity of each case can vary considerably.
It is important to note that therapies and medical treatments designed to resolve the condition -- at least as successfully as medically possible -- are likely to be incredibly expensive and these costs should not be borne by a victim of negligence or recklessness.
It may be appropriate to pursue financial compensation through a civil lawsuit.
