3. Brain tumor
A brain tumor is something that can be extremely worrying and the immediate threat to life is obviously the major cause for concern for anyone suffering from this medical emergency, but the aftermath of a brain tumor is something that survivors have to confront at some point down the line.
Aphasia is one of the potential complications that a person who suffers a brain tumor may be susceptible to developing and usually, only time is a useful indicator as to whether or not this likely.
If the tumor occurs in the left-hand side of the brain, it is much more likely that a person will develop aphasia than if the tumor has developed in the right-hand side of the brain.
Most people who have suffered a brain tumor and lived to tell the tale would probably confirm that every day of life after something like that is a blessing, and so perhaps aphasia is something they can face head-on.
