Dyslexia can be a very problematic
condition that particularly affects a person’s daily living activities.
However, it is not one of those well known conditions like cancer, AIDS, and
the likes. To understand how dyslexia affects people, specifically adults, you
must first understand what dyslexia is, its causes, severity, and prevalence.
What Is Dyslexia?
Dyslexia is basically a condition
that presents a person’s difficulty in processing information that is usually
related to short-term memory deficiency and visual coordination. If you have
this condition, your short-term memory would be particularly weak. It can be
either your auditory or visual memory that is affected or both. Due to this,
being a dyslexic person, it would be difficult for you to learn the connection
between the spoken sound and the written symbol.
It is mainly categorized to be as a
learning disability, since it mainly affects the vital areas in which learning
is related to. Since auditory and visual skills are needed in learning, dyslexia
can make one disabled in this field.
How
Severe Can One Be?
The severity and range of the
condition can vary widely for dyslexic people. The main problem areas of
difficulty would be reading, spelling, numeration, writing, time-keeping and
personal organization. The degree of the effect on an individual can be
observed from mild spelling and reading difficulties to severe problems on
organization or even complete illiteracy. There are no typical cases for
dyslexia, since each case can be unique from one another.
Diagnosis
Some people do not even know that
they are dyslexic; while there are a huge number of people, who are only
diagnosed when they have reached adulthood already. This may be due to the
unpopularity of the condition. Sometimes, it can be misdiagnosed too to be as a
different condition that may present similar symptoms.
What
Are The Causes?
There is no pinpointed cause of
dyslexia, even though much research has been conducted to be able to explain
its main cause. However, there are some researches that have gathered some
relevant findings on the condition. Some neurological research suggests that a
person who has this condition may have some abnormality on how his or her
brain’s left hemisphere functions. This is relevant since the left hemisphere
is the one that controls your lexical system.
Cognitive research, however, in the
past years has mainly focused on the possibility that the cause is related to
having problems with phonological awareness, which is one’s awareness of specific
speech sounds in words. Additionally, there is a speculation that such problems
are somewhat related to a specific portion of the brain.
Whatever the cause may be, there
appears little doubt that a lot of people having literacy problems really do
experience sound insensitivity in different ways. Due to this deficit, reading
problems often occurs. What is also obvious is that even though the cause of
the problems can be multi-causal and can be different from one person to
another, they can still be the main source of intense frustration and
depression for any dyslexic person.
Incidence
And Prevalence
The estimated incidences of dyslexia
can vary greatly every year. It is estimated that it occurs from about to 4-10%
of the population. It is also believed that prevalence in males is four times
greater than with females.
General
Effects In Adulthood
Dyslexia is a condition that is
quite hard to recognize. It is also one condition that most people who have it
try to hide. Simple tasks like filling in forms, taking phone messages, or even
completing timesheets can already be major problems when you have this
condition.
