Character Bruce Willis leaves the cinema for suffering from aphasia
Neurology Primary progressive aphasia: when dementia arrives in full working life
The famous actor Bruce Willis leaves the cinema because he suffers from aphasia, as announced by his family on the networks.
We clear up some doubts about this symptom, which is not a disease since it is a manifestation of injuries due to other causes.
What is aphasia?
It is an
alteration of language due to brain damage
in the areas that control and are involved in that function.
The disorder affects a person's ability to communicate as it can make reading, writing, and speaking difficult.
Why does it occur?
It can be caused by acquired brain damage, a sudden or sudden injury to the brain caused, for example, by a
cerebrovascular accident (such as a stroke)
, which accounts for 95% of cases of acquired brain damage.
Blood flow doesn't reach all of the brain tissue, and the lack of oxygen kills cells in those unperturbed areas.
It can also be due to a
tumor, head injury, or infection
.
Likewise, the cause may be a
neurodegenerative disease
(Parkinson's, Alzheimer's...), in which language is progressively lost.
This dementia that affects language is rare and is called primary progressive aphasia.
In cases of acquired brain damage, it can improve through rehabilitation, while if it is due to a neurodegenerative disease, the patient will progressively worsen.
Who is affected?
In principle it can affect anyone and at any age, including children, but it is not usual.
It usually occurs in
middle-aged or older people
.
types of aphasia
Depending on the damaged brain areas, the patient will manifest different language problems affecting expression, comprehension, reading, writing or repetition.
As the Asociación Ayuda Aphasia states on its website, within the aphasias produced
by acquired brain damage, there are up to eight typologies
: Broca's, anomic, conduction, global, Wernicke's, motor transcortical, sensory transcortical and mixed transcortical.
Within the
primary progressive aphasias, there are three variants
: non-fluent, logopenic and semantic.
None of them is the same as another, each one has different manifestations.
In addition to the types, patients can suffer from different degrees of severity (mild, moderate or severe).
How is it diagnosed? Are there first symptoms?
Sometimes patients cannot build sentences and use short phrases or 2-3 words to communicate.
The order of the words may not be correct or what they say does not make sense.
It can also occur when writing (things that do not make sense or are incorrect, that do not correspond to what they are saying) or they cannot understand what is being said to them.
To confirm the diagnosis, specialists will perform
neuroimaging tests
, both magnetic resonance imaging and functional neuroimaging with PET.
In cases of Primary Progressive Aphasia, being due to a neurodegenerative disease, it is very difficult to diagnose (the disease and the subtype), so the assessment may take more than 3 hours, regardless of neuroimaging tests.
How is the treatment?
The recovery of patients
will depend on the location and extent of brain tissue damage
.
The degree of language impairment (when it was detected) or the level of education also influences
Rehabilitation with speech and language therapy will be necessary to help the patient regain communication skills.
It includes speech therapy, repetition of words, writing...
In the case of Primary Progressive Aphasia, therapy tries to maintain the ability to communicate for as long as possible, although being degenerative there will come a time when they will not be able to communicate in any way.
