Autism Spectrum Disorder Essays - Psychiatry, Psychiatric Diagnosis

Autism Spectrum Disorder Autism Spectrum Disorder (ASD) is a disorder of brain development. The article, European Child Adolescent Psychiatry, focuses on the difficulties in social interaction, verbal and nonverbal communication and repetitive behaviors that people with autism suffer. There are three different types of Autism Spectrum Disorders: Autistic Disorder, Asperger Syndrome, and Pervasive Development Disorder-Not Otherwise Specified. Autism tends to start showing around the ages of 2 and 3 or as early as 18 months. It is estimated that 1 in 68 children will have autism in the United States.; that being 1 in 42 boys and 1 in 189 girls. Social challenges are one of the biggest difficulties autistic people will suffer from. As new born babies grow, they start to become social by nature. For example, they engage with other faces, look towards sounds they hear around them, or grasp a finger. On the other hand, children who are born with autism have trouble with these specific things. Symptoms will start to show in an infant by 8 to 10 months of age. They won't respond to their name, their interest in people will reduce, and their babbling will delay. From 12 to 36 months, children with autism will have difficulty playing social games and would rather play alone. This can result with emotions of anger and discomfort from the child. Autistic children have a hard time controlling their emotions. When they don't get what they want, their behavior can seem to be very uncontrollable because they start to self harm such as: head banging, hair pulling, or self-biting. Speech delay is another challenge this article mentions that autistic people suffer from. Some common things that children by the age of 3 do is babbling, know how to say a word or two, look the direction when their name is said, point to objects they want. When they are given something they don't like, they know how to show it or say "no." Children with autism can't seem to do these things. Therapy does tend to help an autistic person learn to use spoken language and communicate. Pictures, sign language, and word processors are some examples of how autistic children and adults learn their communication skills. When their language does start to develop, they may use speech in unusual ways. For instance, saying a sentence that doesn't make sense or repeating the same word/ phrase over and over again. The third symptom autistic people suffer from is repetitive behaviors. Hand-flipping, rocking, and jumping are some common repetitive behaviors. They like things a certain way so they'll rearrange objects to their likings. When they play with toys, some will spend most of the time lining them up in a specific way instead of actually playing with them. Some have the same daily routine and they tend to feel anxiety or stressed if something is out of order. Repetitive behaviors can also result in unusual obsessions. As autistic children grow older or into adults, they start to gain interest in numbers, symbols, dates or science topics. Since this is a disorder one of my family members suffers from, I wanted to bring more awareness to the topic. People who suffer from autism are not different, they are special in their own unique way. The three main points I will be focusing on in my speech are the difficulties in social interaction, verbal and nonverbal communication and repetitive behaviors that people with autism suffer. These three main points relate to my thesis because they give insight on what it is like to have autism. I can find more qualified research about this disorder by reading articles or journals about test being done on those who suffer from autism.

Las Vegas Geology Highlights

Las Vegas Geology Highlights The glittering city of Las Vegas has done all it can to blot out the desert. But the region is a wonderland of natural attractions, too. Start with the Desert The American desert is a world-class destination all by itself, of course. Its such an iconic setting, familiar from Western movies, music videos, and car ads, that it feels like home even the first time you go there. Any place in the desert is special, but there are really noteworthy sites near Las Vegas. As you arrive, look around and drink in the sight of endless stone. Las Vegas Valley is a downdropped basin typical of hundreds in the Basin and Range, the geologic province that extends over all of Nevada and a little beyond it on all sides. Over the last 25 million years or so, the Earths crust here has been stretched in an east-west direction to around 150 percent of its former width, and the surface rocks have broken into strips of mountains running north-south. As a result the hot material beneath has bulged upward, turning Nevada into a high plateau rich in metal ores and geothermal energy. Numerous earthquakes have been recorded there during this century as the areas tectonic activity continues. The high elevation and the upwind barrier of the Sierra Nevada and Cascade Range on the west has made the Basin and Range a very dry place, one where the mountains remain bare and settlements sparse. Typical desert landforms- playas, dunes, desert pavement, arroyos, alluvial fans and bajadas- are plentiful, and bedrock outcrops and fault traces are well exposed. Geologists love deserts. Just Add Water Las Vegas was once a small settlement named Bringhurst, but it got its current name from the grasslands (las vegas, the meadows) that once grew in the valley. In the desert, grass represents a shallow water table, and in the Las Vegas Valley grass was a sign of the natural faults that force the water table near the ground surface there. Las Vegas languished as a tiny railroad town, serving the nearby mines, until the Colorado River was dammed to create Lake Mead in the 1930s. The city has also exploited the aquifers beneath the Las Vegas Valley so that even if the city vanished tomorrow, the meadows would not return. The availability of enough water to boat in and fill pools helped turn Las Vegas into the tourist destination it is today. While the Las Vegas Strip makes spectacular playthings out of water, the rest of the city tends to landscape itself in gravel and cactus. The University of Nevada campus here is an elegant example of this approach, and worth a visit just for the grounds. The geology department building has hallways lined with display cases full of excellent rock and mineral specimens, too. Las Vegas Geologic Sites There are many beautiful places to see while youre in town. Three great national parks- Grand Canyon, Zion and Death Valley- are within reach for budget travelers, but let me focus on places nearer Las Vegas. Just west of the city is Red Rock Canyon Conservation Area, a prime destination for rock climbers. But you can just take a slow drive through the colorful formations if you like. One of the geologic highlights is an excellent exposure of the dramatic Keystone Thrust, where ancient crustal motions 65 million years ago shoved great thicknesses of gray limestone on top of younger beds of red sandstone. An hour or so northeast of Las Vegas is Valley of Fire, Nevadas first state park. The geologic setting is similar to Red Rock, but in addition this park features many ancient petroglyphs, rock art left by the local tribes including the mysterious Anasazi. Take my Valley of Fire tour here.About.coms Betsy Malloy has her own photo tour.Heres visitor information for Valley of Fire daytrippers.Try a guided 4WDÂ  of Valley of Fire. Both Red Rock Canyon and Valley of Fire are places that display the Sevier Thrust Belt, a gigantic zone of tectonic upheaval that stretches from the Las Vegas area into Canada. The thrust belt records a continental collision far to the west, on the continents edge, during Cretaceous times about 80 million years ago. There are other places near Las Vegas where you can see its signs. To the north of Las Vegas is the understated Upper Las Vegas Wash, where locals come to get away from it all while geologists come to explore the rich fossil record. Take a visit. To the south, you can take trails down to the Colorado River valley below Hoover Dam. And many more destinations are listed in my Nevada Geology category. Maybe a desert hot spring or an all-terrain vehicle tour is more to your liking. Given all these possibilities, Im about ready to go live there full time myself. PS: Among the people who DO live there amidst the tinsel and the scenery are some righteous salt-of-the-earth types, proud of their small desert towns. After youve had your fill of Las Vegas, why not unwind in a quiet little place like Blue Diamond, Nevada, the town that sheetrock built.
