Definition: Autism is a general term for a group of complex disorders of brain development. These disorders are characterized, in varying degrees, by difficulties in social interaction, verbal and nonverbal communication and repetitive behaviours. In recent times all autism disorders were merged into one umbrella diagnosis of Autism spectrum disorders (ASD).
Symptoms and Treatment: Autism spectrum disorders (ASD) are characterized by social-interaction difficulties, communication challenges and a tendency to engage in repetitive behaviors. However, symptoms and their severity vary widely across these three core areas. Taken together, they may result in relatively mild challenges for someone on the high functioning end of the autism spectrum. Each child or adult with autism is unique so, each autism intervention plan should be tailored to address specific needs. Intervention can involve behavioral treatments, medicines or both. Many persons with autism have additional medical conditions such as sleep disturbance, seizures and gastrointestinal (GI) distress. Addressing these conditions can improve attention, learning and related behaviors.
Statistics: In Belgium Autism statistics were resulted as that in pharmacokinetic studies, researchers have demonstrated that ethylmercury has a significantly shorter half-life than does methylmercury. In one pilot pharmacokinetic study, researchers examined concentrations of total mercury in blood, urine, and stool samples of infants 3 to 28 days after vaccination with TCVs. Forty full-term infants, half of whom were 2 months of age and half of whom were 6 months of age, received TCVs; 21 infants received thimerosal-free vaccines and served as the controls. Mercury was detectable in 12 of 17 tested samples from 2-month-old subjects and in 9 of 16 tested samples from the 6-month-old subjects in the study group.
