Causes of autism and its symptoms and treatment Autism is a complex disorder and central nervous system characterized by three fundamental characteristics are: Problem in the interaction with the community. Defect in the communication verbal and nonverbal. Repeated pattern of behavior with the interests of a narrow and constrained There are a number of symptoms often associated with autism, and most who suffer from autism have a problem with the use of language and the formation of relationships, and also in the interpretation of what is going on in the outside world around them or respond adequately to it. And autism can be defined by the behavior and attitudes was possible in the development of the nervous system begins in early childhood and in spite of the diagnosis of autism can not be done only when the child reaches the age of pre-school or school age, the signs and symptoms of autism can appear when the child at the age of 12 to 18 months, as the behaviors special unite almost certain in most cases, at the age of three years, and can be identified at preschool age (5 years) the emergence of delayed language acquisition which is the first thing that appears on the children who are affected by the disease in very severely affected children, while children who are better off Higher functioning they know in general problematic behavior when they reach the age of 4 to 5 years, or social problems at the age of late, it continues to autism throughout the life of the infected person, although some of those infected have the ability to adjust and learn to modify their behavior to some extent. Causes of autism: Most cases the cause is unknown, however, research strongly suggests genetic component as well as the environmental and immunologic immunological and metabolic impact on disease progression. In terms of genetic factor As seems to scientists no single gene is the culprit but the number of different genes, which when they meet together combine together, they increase the risk of autism, and in families where one child with autism is likely to be infected another child from 3 to 8 percent, in the twins who grow up from one egg monozygotic twins in the rate of infection if one of them wounded the other 30 percent, as indicated by several research that the rate of infection in children with first-degree relatives of children with be greater than in relatives of normal children. In some children have autism is linked to a condition such as infection at birth, congenital infections virus rubella virus, and Cytomegalovirus toxoplasmosis and some genetic diseases such as Tuberous Sclerosis and some diseases of the fetus after birth, such as bacterial meningitis, does not consider these diseases are the cause of autism as most children with these diseases do not suffer from autism. Exposure to some environmental factors interact with genetic factors in some families to increase the risk of autism. The researchers and scientists develop theories to explain the cause of autism but did not prove these theories, including the child's exposure to mercury found in some vaccines as a preservative or a child's vulnerability to psychological trauma, especially caused by bad parenting( bad parenting). Symptoms of Autism: 1- Impaired social interaction And examples of the lack of use of body language and expressions of others words such as eye contact and facial expressions, signs, and the lack of awareness of the feelings of others and do not express emotions such as pleasure (laughing) or sadness (crying) and remain in isolation and a preference for unity to exist with others and do not respond to others and the difficulty of interaction with them , and failure in the work of friendship with peers and an unwillingness to embrace, and not responding to oral speech in a timely manner as if he is deaf. 2- Impaired communication For example, non-acquisition of spoken language or speech, and when there is speech and language are unusual in their content, type and difficulty expressing wants and needs to speak with or without, and repeat the words spoken and the inability to dialogue began or continued it, and the lack or absence of games imaginary. 3- he activities and behaviors, interests confined and constrained For example, insistence on routine and resistance to change and act in a manner of constraint or nature like a ritual and repeat the movements of the body such as the knock of the hand or head-banging and spinning, shaking and like walking on your toes and put things in line, and a preoccupation with the particulars of things and fascination movements repeated like turning off the light and illumination, or concerns limited and narrow interest such as calendar, dates, numbers, and the climate. There are a number of features associated with the actions that can be seen in some people with autism, including: Cognitive function: P Autism occurs at all levels of intelligence and with that about 75 percent of people with autism have an IQ lower than their average, about 25 percent have average or above average intelligence of the average in a particular area such as mathematics. Neurologic function: Occur cramps for about 25 to 35 percent of children with autism, and these cases are resistant to treatment and do not respond to him, and up tensions to a head in early childhood and at puberty, and increase the risk of convulsions in children with autism who also suffer from mental retardation At the same time belong to the families of individuals with a history of suffering from autism, but for the motor skills they are developing in some areas and underdeveloped in other areas. Behavioral symptoms: And include: Aggressive or abusive behavior of the self. A significant increase in effectiveness and lack of activity or significantly. Bouts of anger. Lack of attention span. Unusual response to sensory stimuli such as pain, those who suffer from autism show the sensitivity of excess or deficient in their response to pain, as well as it may seem to them terror in response to high voices have no fear when some of them in positions of danger. Sleeping and eating non-natural but may not eat certain types of food. Lack of response of the means of regular education. Play in ways that abnormal and unusual. Link unnatural things. when looking for medical help? If the actions of the child is not normal for a day or two days after he was acting in a manner entirely normal, it is likely that arises about the reason for a simple or to be tired the impact of some kind of pressure, but if it continues for a long time and there were some of the symptoms mentioned above you should visit a pediatrician especially if this happened at the age of 4 to 6 years, however, some parents suspect that something is wrong and worthy of attention at the age of 18 months and express this at the age of two years. The most important of these observations: Seems that the child is surrounded by a poet and as isolated. Not to play and interact with others. That seems obvious or discreet. Seem to have trouble speaking or understanding others talk. Lack of control over tantrums. Insistence on routine and non-change. Repeated acts. And must be assessed in terms of any child if autism over the following: If you do not speak like children at the age of age. If not used to convey signals, such as children at the age of a year. If you did not utter a single word at the age of 16 months. If you do not speak two words at the age of two years. When the loss of child language or social skills. And when one of these signs should not wait, that means a disability - even if they were not the disability due to autism and was caused by another disease - P early diagnosis and intervention have great importance in improving the long-term results for each developmental disorders including autism. Treatment of autism There is no cure for autism yet, whether medical or behavioral means, but with more knowledge about autism are responses to some therapies that are in the form of well-planned educational programs that focus on the development of communication skills and social skills. The pediatrician is usually directed to the child and those interested in specializing in disorders of child development to assess the situation, and some people prefer that the provision of this specialist treatment for their child, but they are free to choose the processor. There are no specific standards for the treatment of autism, and many professionals have different philosophies and practices in the treatment of autism. Children with autism have a capacity to absorb the information that they see all they hear so they learn to watch. People with autism are difficult to understand sentences and lengthy instructions. Treatment includes the development of a child's comprehension and expression of his feelings also includes soothing activities such as music, watching TV, video, and giving the child intervals of rest. Children can people with autism for things that they heard that repeatedly, and can remember the conversations took place offers full video or a book or love him the way to some places. Gradient can be in the education of a child with autism a real invisible things such as juice boxes, and labels on the cans and then this picture boxes and then charge for boxes, and so education is gradually from easy to more difficult things can be used as a Specialist in speech problems. The traditional method of treatment includes special education and the order in each case their actions (behavioral management). There is evidence to suggest that the more the occupational therapy - and the words and actions - early whenever the results were better in the long term. It also includes treatment of interest next to the language and speech therapy and behavior therapy and complementary medicine or alternative medicine and support scientific studies. There are many drugs used in the treatment of autism the most important treatments for seizures, behaviors and emotions associated with autism such as depression and who used his Antidepressants and Antipsychotic drugs which reduce aggressive behavior and repeated at some autistic.
