Autism causes are still a mystery however evidence is pointing to the
fact that there are huge unexplained increases in incidence of autism
( over 287%) and that very often it happens in clusters i.e. groups of
children are diagnosed with autism in the same geographic area.
Suggestions as to why this is the case are debatable. Theories are
based on chromosome abnormalities. This may mean the siblings of a
child with autism are 75 times more likely to develop it themselves.
Another school of thinking is that there is some damage from the
environment and Dr Andrew Wakefield has presented evidence to support
his argument that vaccines are at least a contributing factor.
especially the MMR vaccine.
Autism can vary in the way it effects people and also the severity.
Diagnosis is placed on something referred to as the 'Autistic
Spectrum'. Milder forms of the condition include Asperger's syndrome.
The types of symptoms that come with autism might include difficulties
in communicating socially and not being able to relate with others in
appropriate ways. Autism affects the ability to form friendships and
relationships. Very often in the developmental stages of childhood,
play is affected and sometimes people with autism find it difficult to
connect with the 'real world' so to speak. Very often the diagnosis of
autism isn't made until the child grows older and there may be showing
signs of not developing at check ups and usually this is indicated by
their social behaviour. When the child starts school these symptoms
are often perceived as behaviour problems such as possessive or
repetitive behaviours, often they have difficulty in adapting to
changes in routine. Their coordination may be poor either with
movement or holding pens and such like. In some cases the child may
have difficulty in making friends at school and in part this is due to
the inability to read non-verbal communication form others and respond
appropriately. In many cases the child develops other learning
difficulties that can then follow them through life. However children
with autism may be gifted in a certain area like art, mathematics or
music for example....
