When
the brain forgets how to speak: the case of Bruce Willis and neurobiology in
real life.
I learned that the famous
Hollywood actor named Bruce Willis, retired from acting due to a
neurobiological condition exposed in this course called aphasia: this means
that the brain starts to fail in functions as basic as speaking, understanding
or even controlling our emotions. As we have seen in the course, aphasia is a
language disturbance that occurs when two key areas in the brain become
damaged: Broca's area (which helps form words and speech), and Wernicke's area
(which allows us to understand and process what others tell us). When these
areas stop working well, the person may speak with difficulty, use the wrong
words or not understand what he or she hears. In addition to this report, a
special communiqué following Bruce's retirement disclosed that the diagnosis
went further; he was diagnosed with frontotemporal dementia, a progressive
disease that mainly affects the frontal and temporal lobes of the brain. These
regions are not only responsible for language, but also for such important
things as personality, emotions, memory and social behavior.
From the point of view of the
nervous system, what is happening is that the neurons in these areas begin to
die little by little. Sometimes it is because abnormal prion-like proteins
accumulate and damage the cell and its synaptic connections, in other cases
strokes occur that damage key areas of the cortical or subcortical regions. The
sad thing about this case is how a medical condition can change someone's life
so much as not being able to say what we think, or not understanding what our
loved ones tell us, but it is not just one point of the brain that fails, but a
series of connections between regions such as the neocortex, the thalamus, the
hippocampus. We also need to talk about something that is often forgotten: the
emotional impact. When someone like Bruce, who made his living from acting and
communication, loses that ability, he not only faces a medical problem, but an
identity crisis. And his family experiences it as well.
In short, the nervous system
is involved in every single thing we do (talking, thinking, feeling, deciding)
and when it fails, it shows us how fragile we are. In the end, understanding
how our brain works (and how it can fail) is a way to better understand
ourselves as people.
