Autism And The Amygdala In The Brain

“Autism is a disorder characterized by severe difficulties in social interaction and communication and with unusual behaviors.” (Dr. David Pauls 2003). This disorder is assumed to be caused by genetics, environmental toxins and/or prenatal care. (Harvard Medical School 2013). Social behaviors/interactions affected by Autism is the ability to process learning, communication and family/peer relationships. Autism is a disorder in which its cause makes it impossible to prevent and it takes a toll on its victim’s everyday life tasks.

Autism is a rare disease that can be characterized by a “neurodevelopmental disorder categorized by the inability to relate to and perceive the environment in the realistic manner.” (Anthes, 1997) The signs of autism are mainly found in infants to young children usually between the ages of newborn to two years. The main symptoms that are discussed are “impairment in social interaction fixation of inanimate objects, inability to communicate normally, and resistance to changes in their daily routine.” (Anthes, 1997) Autism is a very understood disease but one thing most people do not know is that autism not only effects a child’s life mentally and physically, it also effects their social ability to have friends, play normally and even grow up

Autism is characterized as a neurodevelopmental disorder that affects social interactions, nonverbal and verbal communication, and restricted and repetitive behavior. On a global scale, autism was estimated to affect 21.7 million people in 2013, and the number continues to rise as time persists. Children are often diagnosed while they are infants, usually in the first two years of life, when parents notice odd behaviors such as assembling toys or stacking of objects. It is not yet well understood how autism occurs, but we do know that autism affects information processing in the brain by changing the way nerve cells and their synapses connect and organize. Autism is one of the three disorders that make up the Autism Spectrum, the second is

Autism is a syndrome that is characterized by the impairment of social interaction skills, verbal and nonverbal communication, and a decreased interest in participating in a variety of activities. In 1943, Kanner, the man who is attributed with the identification of this disease, hypothesized that autism might be a biological disorder as opposed to a psychological one. Numerous studies have been conducted supporting Kanner’s hypothesis. These studies have ranged from examining the effects of rubella to investigating certain purine metabolic disorders as possible etiological agents. Recently, the areas of neuroanatomy, neurochemistry, and genetics have played a crucial role in developing a clearer picture into

When it comes to autism spectrum disorder (ASD), many people don't understand what the disability is or how children who suffer from ASD live their everyday lives. “Autism is a serious nuerodevelopmental disorder that impairs the ability to communicate and interact.” (Psychology Today, 2015). Usually, autism is diagnosed in children from as early as the age of 2 and symptoms can impact individuals throughout their lifespan. Common symptoms of autism include impaired social interactions, impaired verbal and nonverbal communication, problems processing information from the senses, and restricted and repetitive patterns of behavior. Anxiety is also common among children with ASD, and parents of children with ASD are more likely

Chapter 1 focuses on autism, Pervasive Developmental Disorders (PDDs) and other Autistic Spectrum Disorders (ASDs). Described in 1943 by Dr. Leo Kanner, autism (also known as autistic disorder, childhood autism, or infantile disorder) is one of the PDDs along with Rett's disorder, Childhood Disintegrative Disorder (CDD) referred to as Heller's syndrome, Asperger disorder, and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS). Rett's is a rare genetic abnormality affecting brain development in girls. There are treatments available, but there is no known cure. Asperger disorder affects an individual's ability to socialize and communicate effectively. Individuals with Asperger disorder may be socially awkward and have a compulsive

Autism can be defined as a mental condition, present from early childhood, characterized by difficulty in communicating and forming relationships with other people and in using language and abstract concepts (Merriam-Webster Online). Autism can have a wide variety of severity; there is the autism spectrum, which tells educators, whether the child is higher up or lower on the spectrum, or if they are in the middle. There has been a steady increase in the number of students who have been diagnosed with autism, according to Deris (2013); the number of children who have autism went from one in 150 in 2000, almost to one in 88 in 2008.

Autism is defined as the brain disorder that begins in early childhood and persists throughout adulthood. Autism affects three areas of human development: (1) verbal and nonverbal communication, (2) social interaction, and (3) creative or imaginative play. Autism is considered a severe disorder and developmental disability that prevents individuals from properly understanding what they see, hear and sense. The cause of autism remains unknown. Current theories indicate a problem with the function or structure of the central nervous system. This essay overviews the history of autism and the Diagnostic and Statistical Manual of Mental Disorders (DSM). It provides an idea of the population and causes of autism. It takes about the program services and the current operational issues related to autism.

Symptoms typically are apparent before children turn 3 years old. (7). When individuals are born as an identical twin or have first degree relatives who have autism, they are automatically at a higher risk for developing it themselves. Other risk factors include immune dysregulation, altered short chain fatty acids, genetic mutations involving the metabolism of vitamin D, infections, teratogens, or antibodies maternally. For every 68 boys who are born, 1 will likely have autism, as boys are about five times more likely to present with autism than girls are. (3). When the brains of patients with Autism Spectrum Disorder are studied and compared with those who do not have the disorder, there are obvious differences. In the Autism Spectrum Disorder brain, there are alterations to the striatal circuits, a dysfunction in canonical neural circuits, and an abnormal basal ganglion connectivity. These striatal dysfunctions of the brain are evidence as to why abnormal behaviors occur in autistic patients (repetitive grooming, stereotypic motor routines, and deficits in social interaction and decision-making). There may even be evidence that links genetics to these specific neural circuits. (8). When MRI’s are taken on young autistic patients, the hyperplasia of their cerebral cortex can often be seen. Because the frontal and temporal lobes are important for social functioning and language development, these anatomical anomalies are likely to underlie the pathophysiology of autism.

As I said earlier, autism is caused by genetics, environmental factors, and delayed brain development. Everyone on the spectrum is effected by autism in their own unique way. The effects of autism are broken down into five main categories; communication, social interaction, sensory impairments, play, and overall behavior. Some things that autistic individuals struggle with in regard to communication is that their language develops slowly, they use their own made up hand signals instead of words, and have short attention spans. Next, autistic children do not attempt to make friends because they would rather spend time alone, and they struggle with social cues

Autism is a brain based disorder that causes social-communication challenges. Autism is often diagnosed when children are very young. They can be diagnosed as early as 18 months according to the Autism Spectrum Disorder. Many expecting parents will prepare for a pregnancy by the usual healthy diet to make sure that they have a healthy baby, however, many children are still getting diagnosed with autism every day. There is a statistic stated on the Autism Spectrum Disorder that about 1 in every 68 children in the United States currently has autism. There are many different beliefs people have for as to what causes autism, but there still has not yet been a found cure. There needs to be a stronger effort in the medical fields to find the leading cause of autism.

With the rate of autism being diagnosed on the rise, the amount of research and interest in the disorder has risen as well. Some research suggests that over the past two decades the occurrence of autism has increased from approximately 2-5 per 10,000 births to about 1-5 per 1,000 births (Acosta & Pearl, 2004; Fatemi et al., 2012). Still others report that the occurrence is as high as 1 in 150 kids (Amaral, Schumann, & Nordhal, 2008). Even though the spectrum of autistic disorders has been studied since 1943, there have still not been any consistent nor persuasive causes or markers, either biological or clinical, identified with autism and its range of disorders (Santangelo & Tsatsanis, 2005). In fact, even with all of the advancements in genetic research technology and the increasing interest in autism, researchers can still only account for approximately 5-15% of autistic cases (Rogers et al., 2013).

Autism is a developmental disorder that affects brain functions and impairs an individual’s ability to communicate and interact with others.

Just as there is no duplicate case of autism, there is no one cause. Alternatively, there is a list of causes. Some of the most common include genetic mutation and predisposition as well as environmental factors. Some research shows that women can reduce the chance of their children being autistic by increasing folic acid intake before and following conception. Other research shows that “advanced paternal age can affect the child’s risk” of being

Autism is a mental condition, present from early childhood, characterized by difficulty in communicating and forming relationships with other people and in using language and abstract concepts (“Autism” Def). It’s a disability that affects a person’s communication skills and/or changes in behavior. Autism is usually diagnosed before three years of age and has a lifelong persistence. The causes of this disorder is unclear and there is currently no cure for it. There are two core characteristics of autism. The first being a deficiency in social communication and social interaction. The second is a restricted, repetitive patterns of behaviors, interests, and activities. Clinical features of autism include walking on tiptoes, lack of eye contact, extreme dislike of certain foods or sounds, poor communication skills, repetitive behaviors, and
