Children who have siblings diagnosed with autism spectrum disorder are known to be at greater risk of receiving a diagnosis of autism spectrum disorder than other similar children who do not have a family history of autism. The reason for this increased risk of vulnerability appears to be genetic in nature, leading to an increased risk of chromosomal abnormalities. Specifically, abnormalities found on chromosomes 2, 3, 5, 7 and 15 are associated with an increased risk of autism. Say no to plagiarism.

If this latest research proves true, it would help explain why more males develop autism than females. Genetically, males carry a single X chromosome and a single Y chromosome, while females have two X chromosomes. Genetic errors on one X chromosome can be deleted in females by the other X chromosome present. This is not the case, however, for males, whose Y chromosome cannot erase X errors. Consequently, if errors on the X chromosome were responsible for vulnerability to autism, males would be more likely than females to inherit and express such errors as they develop. The form or mechanism by which genetic contributions might create a vulnerability to autism is unclear at this time. time. Genetics can predispose children to be particularly sensitive to toxins, to have fragile metabolic systems that cause them difficulty digesting certain foods, to be unable to produce particular enzymes needed for effective digestion, etc. The importance of a person-centred approach, focusing on the individual and not on the diagnosis. Person-centred reviews are a way to develop more responsive and person-centred services and to develop living descriptions of how people want to live. The purpose of the review is to focus on what “works” and what “doesn't work” from different perspectives. With the information gathered through a review we are able to start changing people's lives (by developing actions during the review). By placing the person fully at the center of the review and including families, promoting inclusion and creating descriptions of how the individual wants to live, person-centred reviews lead to change. Living descriptions can be developed in a person-centered plan. Please note: this is just an example. Get a custom paper from our expert writers now.

This can help them cope with change more easily. Provide a step-by-step list of instructions for completing daily tasks, such as getting ready for school or taking a shower. A wall chart with images illustrating each step can be a good way to present this information. This can be helpful for children and higher functioning adults. Develop a regular routine for the day including set times for meals, activities and sleep. Once you've established a routine, avoid changing it if possible. The children and the.
