Autism is a developmental disorder that affects children from birth or in the early months of their lives resulting in delay or deviation from the normal developmental patterns and manifesting in disorderly behaviors in:
1. Social relationships and interactions
2. Activities and interests and
3. Language and communication.
When there are noticeable changes in the above behavioral patterns in children, then such a child may probably be autistic. A prevalence rate of almost 1 in 100 people in the UK fall under the Autism Spectrum Disorder. Although autism can be evident as early as birth or few months after birth, it is possible that the specific developmental progression may not be apparent until after many months or even years.
There are instances where a child may have an unusual delay in development which may be confused with autism since the diagnosis of this disorder is somewhat difficult due to the wide range of behavioral differences in children presumed to be autistic. However, Autism may be inadvertently overlooked in children with an above average mental ability which means that any odd or unusual behavior or abnormalities may be viewed and dismissed as mild or transient.
Possible Causes of Autism
The cause of autism is still unknown and no concrete scientific evidence exists to prove its cause. However, it is generally believed by medical experts that autism could be due to some form of damage to the brain prenatally. Factors that may be responsible for autism include:-
(i) Viral agents
(ii) Immune intolerance
(iii) Prenatal anoxia
(v) Metabolic disorders
These factors can pre –dispose children having autism to additional conditions such as learning disabilities, identified medical conditions which may include, fragile X syndrome, neurofibromatosis and tuberculosis. However, this explanation is not exclusive as there are children with damage to the brain but who do not have autism.
Key points to note about Autism
- Autism is an organic disorder that affects several areas of a child’s development
2. Babies with autism can sometimes display characteristic features of gaze social development, hearing and play.
3. Autism is present from birth or soon after birth. However, the nature of the disorder may mean that diagnosis is delayed for months or years.
4. Learning disabilities may or may not be visible pr present in children with autism.
5. Nurses, nannies and care givers working with babies and young children are in a better and prime position to detect if a child has the autistic spectrum or not. He or she can then refer the family for specialized assessment and management of the disorder.
6. Early detection of autism can help in improving long term function in the affected children and help families of these affected children.
