Learning disabilities, attention deficit hyperactivity disorder
and fetal alcohol spectrum disorders are the most prevalent exceptionalities
among students of the British Columbia public school system. There is a
plethora of material regarding these exceptionalities, especially as new
research continuously updates information regarding how these exceptionalities
are defined, diagnosed, and accommodated. This précis will summarise the current
information regarding those three exceptionalities.
The first
exceptionality examined is learning disabilities (LD). Learning disabilities
are defined as disorders that effect an individual’s learning in a narrow range
of areas. Learning disabilities can be classified by either the function
impaired or by the stage of information processing. Learning disabilities are
commonly diagnosed by assessing the difference between achievement and
intelligence quotient, although there is disagreement as to whether this is
appropriate or not (Kavale, 2011). Learning disabilities are usually incurable,
however there are various interventions. Some of these interventions focus on teaching
LD students the skills in which they have deficits or skills which will allow
them to be more efficient learners, while others focus on bypassing the deficit
with technology or human assistance (Woodcock & Vialle, 2011).
The second exceptionality encompasses
attention deficit hyperactivity disorder (ADHD). This disorder is defined as a developmental
disorder characterised by the inability to pay attention and hyperactivity.
There are three broad categories within this exceptionality: impulsive, inattentive,
and combined. The cause or causes of ADHD are unknown although several have
been suggested. These include genetics, environment, diet, and social factors. There
is significant controversy regarding ADHD as the rate of diagnosis has
increased. Some researchers suggest that several disorders are misdiagnosed as ADHD
while others believe that ADHD itself is a social construction. Diagnosis ADHD
is through psychological assessment. Treatment of ADHD is often through
medication and behavioural modification. The most common medications for
treatment are stimulants such as Ritalin (Döpfner et al, 2011). In the classroom,
effective adaptions are through the use of behaviour modification and the
application of positive and negative reinforcers (BCED).
The final exceptionality encompasses fetal
alcohol syndrome (FAS) and fetal alcohol spectrum disorders (FASD). FAS are a
pattern of mental and physical defects caused by the prenatal consumption of
alcohol. The main effect of FAS is permanent damage to the central nervous
system. This leads to impairment of mental function, including impairments to
memory and reasoning (Green et al, 2008). There are also secondary effects such
as growth deficiencies and facial abnormalities. The term FASD was developed to
include fetal alcohol syndrome (FAS) as well as a range of other effects caused
by prenatal alcohol exposure. There is no one clinical feature used to diagnose
FAS and FASD. There is a general consensus in the definition of FAS but there
is debate as to what defines FASD. There is no cure or treatment for FASD,
although there may be ways in which to manage the secondary effects of this
disorder (such as poor memory) (Rasmussen et al, 2009).
This précis has summarised the current
information on the three main exceptionalities encountered in the public school
system. A common factor with all of these articles is the uncertainty in the
definition, diagnosis, and treatment of these exceptionalities. While there is
consensus in certain areas (such the definition of FAS), there is a lot of
variability in others (especially treatment and adaption). Some of this
variability is due to differing purposes that these articles were written for.
