Neurological damage and changes in the brain associated with autism. The nervous system which is known to be a very complex network becomes disrupted by the presence of autism. The disruption results to changes in the manner the brain is wired and set to process information. Such differences can result to self stimulatory behaviors, social dysfunction as well as language problems. The initial signs of autism are the inability of the child to regulate the sensory input involved in processing movement, tactile, auditory, touch, and visual and smell stimuli (Michael, 2000). Autistic children tend to experience sensory integration where some of the senses become either under or over sensitive. For instance, an autistic child may get hold of a soft object such as a cotton wool and feel pain instead of feeling it as soft. On the other hand, feel uncomfortable when they put on clothing as they have a tendency of feeling pain when the fabric come into contact with their skin. Others under react while others over react to either very loud or soft sound when it gets into their ears. In addition, others feel very comfortable in a very bright light while to some, a dim light is painful to their eyes. Certain foods which are perceived to have a bitter taste can sound very sweet in their mouths or have no taste at all. The same applies to smell, some awful odor may turn out to be a sweet smell to them or have no smell at all. These children have to be constantly under our watch and care since they have a tendency of injuring themselves. They harm their bodies with sharp objects but they don’t notice it since they do not feel any pain at all. They may want to wash their face with very hot water. to them they feel the water to be extremely cold. These different levels of sensory registration are presumed to be associated with the brain’s cerebellum. The cerebellum hampers the person’s ability to regulate his/her sensations and may cause difficulty in comprehending and use of language since language and sensory failure are interconnected (Hill &. Uta, 2003). A study found out that brain cells linked with the central nervous system gets inflamed in persons with autism much higher than in normal persons. Cerebro-spinal fluid depicted an increase in the response of cytokine in children with autism. These outcomes point to the inflammation as a cause in the occurrence of autism disorders (Salmond, 2003). The behavioral and functional changes associated with autism. Autism is considered as a disorder of wide-spectrum as each autistic person exhibits his/her own unique symptoms and characteristics. The following are some of the commonly seen characteristics. In a mild case of autism, the person appears to be socially clumsy, makes countable eye contacts and makes offensive comments. In severe cases, the person has completely been in isolation as he/she is totally disinterested with other people. They tend to miss the cues that we exhibit when you want to get somebody’s attention and the person may not even be aware that you are trying to talk to him/her. An autistic person may not even understand how you are feeling. His/her capacity to empathize with somebody is relatively low and they need constant practice and being reminded in order to improve on this. Also, such children do not like to be cuddled or getting touched (Salmond et al, 2003).
