Autism Through Ages Baffles Science


   For years past people with autism were placed in institutions all over the world. Autism is not a modern problem, even though it has only recently gained vast recognition. It is difficult to discuss the history of autism treatment without paying particular attention to the history of "autism" as a concept and the ways in which autism has been conceptualized and theorized about over the past 100 years.
The ways in which we understand and think about autism have directly and indirectly formed our conceptual responses to autism over the years. The very concept of "treatment" carries with it many presumptions about the nature of autism, its origins and its potential outcomes. The history of autism is not a linear one, and regardless of the past or present debates over treatment, origin or outcome, as more and more studies and research are conducted the greater the understanding of autism will become.
Swiss psychiatrist Eugen Bleuler first introduced the term autism in 1911. Autism and autistic stem from the Greek word "autos," meaning self. The term autism originally referred to a basic disturbance in schizophrenia, in short, an extreme withdrawal of oneself from the fabric of social life, but not excluding oneself.
          Bleuler also coined the term ambivalence to designate one of the major symptoms of schizophrenia, the others being autism, disturbances of effect (emotion) and association (thought disorders). Ambivalence is a coexistence of two opposing drives, desires, feelings or emotions toward the same person, object or goal. The ambivalent person may be unaware of either of the opposing wishes. Bleuler felt that there were normal instances of ambivalence--such as the feeling, after performing an action, that it would have been better to have done the opposite; but the normal person, unlike the schizophrenic, is not prevented by these opposing impulses from deciding and then acting. Bleuler's schizophrenia differs in terms from the Freudian theories, in which ambivalence was described as feelings of love and hate toward the same person. (E.L. Horwitz, "Madness, Magic, and Medicine: The Treatment and Mistreatment of the Mentally Ill." [Lippincott, 1977])
          In the early 1900s, psychologist Carl Gustav Jung introduced the well-known personality types, extroverts and introverts, further broadening Sigmund Freud's psychoanalytical approach. However, this approach appears to have indirectly classified the autistic person as a schizophrenic introvert. Jung saw the activity of the extrovert directed toward the external world and that of the introvert directed inward upon him- or herself. Jung, who removed from the term the sexual character ascribed to it by Freud, called this general activity or drives of the individual the libido. The extrovert is characteristically the active person who is most content when surrounded by people; carried to the neurotic extreme, such behavior appears to constitute an irrational flight into society, where the extrovert's feelings are acted out.
          The introvert, on the other hand, is normally a contemplative individual who enjoys solitude and the inner lifeof ideas and the imagination. Severe introversion was believed to be characteristic of autism and some forms of schizophrenia. (C.G. Jung, "Psychological Types." [tr. 1923, repr. 1970]) Jung did not suggest strict classification of individuals as extroverted or introverted, since each person has tendencies in both directions, although one direction generally predominates. Jung theorized a patient could achieve a state of individuation, or wholeness of self. (E.H. Ackernecht, "A Short History of Psychiatry." [Hafner, 2d ed., rev., 1970])
          In 1944, American Bruno Bettelheim directed the Chicago-based Ortho-genic School for children with emotional problems, placing special emphasis on the treatment of autism. Bettelheim believed that autistic children had been raised in unstimulating environments during the first few years of their lives, when language and motor skills develop. He saw parents unresponsive to their child as an underlying cause of autistic behavior. (L. Wing, ed., "Aspects of Autism." [1988]) Although subsequent studies of the parents of autistic children have discredited Bettelheim's psychological explanation, his ideology carried into the general populace for generations to follow, germinating red herring terms like "refrigerator mother."
          The highly complex treatment of childhood autism began with the early-childhood development pioneers Leo Kanner and Hans Asperger, who each published accounts of this disorder. Kanner published his report in 1943 while at Johns Hopkins. He conducted a case study of 11 children who appeared to share a number of common characteristics that he suggested formed a "unique 'syndrome' not heretofore reported." He titled the article, "Autistic disturbances of affective contact," and characterized the children as possessing, from the very beginning of life, what he called an "extreme autistic aloneness." The following year, Asperger published "Autistic psychopathy in childhood." The article presented a case study of several children whom he described as examples of "a particularly interesting and highly recognizable type of child." Both Kanner and Asperger believed that the children suffered from a fundamental disturbance that gave rise to highly characteristic problems.
They both chose the word autism, a term coined by Bleuler in reference to the aloneness experienced by schizophrenic patients, in order to characterize the nature of the underlying disturbance. The common feature of this disturbance was that the children seemed unable to entertain normal relationships with people.
          In contrast to Bleuler's schizophrenia, the disturbance observed by Kanner and Asperger appeared to have been there from birth. Kanner's paper has become the most quoted, while Asperger's paper, written in German during World War II, was largely ignored. The belief has grown that Asperger described quite a different type of child, not to be confused with the one Kanner described.
Asperger's definition of autism or, as he called it, "autistic psychopathy," is far wider than Kanner's, including cases that showed severe organic damage and those that shaded into normality. In 1943 and 1944, "autistic disturbances" and "autistic psychopathy" became known as syndromes. (U. Frith, "Autism: Explaining the Enigma." [1989]) Asperger's syndrome as defined today is clearly not what Asperger intended, but having this special category has proved clinically useful.
          Kanner's syndrome is often used to indicate the child with a constellation of classic, "nuclear" features, resembling in astonishing detail the features that Kanner identified in his first, inspired description. Again, the category is clinically useful since it communicates a prototypical pattern. From the 1980s through the early 1990s, the cause, prognosis, and treatment of autism were vigorously under study. Research suggested that a genetic defect caused the disorder, which was presumed to be some form of autoimmune disease or degenerative disease of nerve cells in the brain.The preferred treatment for the autistic child was special education, stressing learning in small increments, and a strict behavioral control of the child.
          In general, about half of the children with autism were considered mute; those who remained mute through age 5 were given a poor prognosis for recovery. The children with autism who spoke were given a prognosis that they would fare better, and possibly even recover. (Autism, ENCARTA'95; Computer program; [1995]) Since 1911, the understanding of autism has grown to such a degree that we know there is not yet a cure.
          However, researchers all across the nation are working diligently to produce more information on autism, and possibly a cure. "Cure" means "restoration of health; recovery from disease." To "recover" means "to regain a normal or usual condition, as of health." While "cure" and "recovery" prognoses for autism might have been the expectation of 80s and early 90s, they do not represent expectations today.
Today we know that with highly structured and appropriate interventions the behaviors of a child or adult with autism may change to the point where he or she may appear to no longer have autism to the untrained person. However, while they have changed, they still have the autism.
          In 1995-1996, only 5.6 million children (ages 0 to 21), or about 12 percent of public school children, were enrolled in special education programs. The number of students participating in federal programs for children with disabilities has increased at a faster rate than the total public school enrollment.
          Between 1977 and 1995 alone, the number of students involved in federal programs for children with disabilities increased 47 percent, while the total public school enrollment decreased by 2 percent. These counts are based on reports from the 50 states and submitted to Congress to aid in the enactment of the Individuals with Disabilities Education Act by the National Center for Education Statistics, U.S. Department of Education, "Digest of Education Statistics," 1997.
It is also noted in this study that as early as 1976, as new types of disability categories began to emerge (specific learning disabilities, serious emotional disturbance, multiple disabilities, other health impairments, autism, preschool disabled), the percentages of federal programs for students with mental retardation disability began to lower.
          It is evident that autism as a diagnosis was non-existent prior to the early 1900s, and the people who had what we call autism today were diagnosed with some other disorder. It was not until the mid 1900s that people with autism were no longer institutionalized for their problem. Despite the persistence of old theories, no factors in the psychological environment of a child or adult have been shown to cause autism. There is no proof that autism is due to bad parenting, neglect, abuse or tragedy. Children with autism are not unruly youngsters who choose not to behave. Professionals have long since disproved all of these "causes" and theories. Unfortunately, the general understanding of the word autism hasn't kept up with the newer medical research shared today. It is proven that people with autism can lead happy and productive lives when appropriate supports and therapies are provided.

Workplace Bullying 2



In this blog I will continue my analysis of the article “Workplace Bullying Often Goes Unpunished” which was published on “BusinessNewsDaily.com”. Previously I discussed some statistical information regarding the occurrence of workplace bullying and the characteristics of workplace bullies. On this occasion the statistical information I will be focusing on deals with how individuals react to bullying within the workplace setting.
According to the article, a recent study conducted by the Workplace Bullying Institute revealed that employers are not taking the necessary steps to stop or diminish workplace bullying. In fact, the study states that 25% of employers did not investigate the bullying claims, 31% discounted the bullying claims as “not serious” or considered it routine, 11% defended the bullies, and 5% encouraged the bullying abuse. Personality flaws and deficiencies in work-related skills were two reasons cited by the article as causes of workplace bullying. In addition, the article states that a lack of accountability encouraged bullies to feel safe from facing any consequences as a result of their bullying actions.
What seems to be occurring in the workplace is a feature previously discussed within another blog, which is the normalization of bullying behavior. Employers, which are supposed to be the individuals who set proper behavioral workplace standards, are not fulfilling their expectations. Instead, employers are downplaying bullying behavior and in a manner fueling bullying by accepting its existence. It is often the case that children look up to their parents and follow their example. As a result, it may be that adult bullying inconspicuously leads to bullying in children. It may be that children are observing the bullying behavior of adults, perhaps even their parents, and are mimicking their behaviors. Over time the bullying behaviors may become a “normal” occurrence to children. If this is the case, then perhaps bullying that occurs among adults, such as workplace bullying, is the type of bullying that should be especially targeted by researchers.
An unfortunate statistic revealed by the study is that in 61% of the cases where the workplace bullying incident managed to end, the bullying victim lost their job due to resignation, being fired, or being forced to quit. However, the article does note that “93% of U.S. employees [would] support the enactment of a new law that would protect all workers from reported abusive mistreatment in the workplace.”
The fact that most individuals would support anti-bullying laws offers glimmers of hope for the future. It is uplifting to know the ability to produce legal changes against bullying remains within the reach. Society as a whole seems to acknowledge that the concept of bullying is wrong. However, what seems to be the major problem within society today is the recognition of bullying as an actual problem.

What Causes Autism?


Causes

_
Autism RibbonThere is no known single cause for autism, but it is generally accepted that it is caused by abnormalities in brain structure or function. Brain scans show differences in the shape and structure of the brain in children with autism versus in neurotypical children. Researchers are investigating a number of theories, including the links among heredity, genetics and medical problems.
In many families, there appears to be a pattern of autism or related disabilities, further supporting the theory that the disorder has a genetic basis. While no one gene has been identified as causing autism, researchers are searching for irregular segments of genetic code that children with autism may have inherited. It also appears that some children are born with a susceptibility to autism, but researchers have not yet identified a single "trigger" that causes autism to develop.
Other researchers are investigating the possibility that under certain conditions, a cluster of unstable genes may interfere with brain development, resulting in autism. Still other researchers are investigating problems during pregnancy or delivery as well as environmental factors such as viral infections, metabolic imbalances and exposure to environmental chemicals.

Genetic Vulnerability

Autism tends to occur more frequently than expected among individuals who have certain medical conditions, including Fragile X syndrome, tuberous sclerosis, congenital rubella syndrome, and untreated phenylketonuria (PKU). Some harmful substances ingested during pregnancy also have been associated with an increased risk of autism. 

Environmental Factors

Research indicates other factors besides the genetic component are contributing to the rise in increasing occurrence of autism, such as environmental toxins (e.g. heavy metals such as mercury), which are more prevalent in our environment than in the past. Those with autism (or those at risk) may be especially vulnerable, as their ability to metabolize and detoxify these exposures can be compromised.

Inside the Brain of a Person with Autism


I always wonder what is actually going on inside the brain of a person with Autism. This article provides some insight into this idea. 
Much like a computer, the brain relies on intricate wiring to process and transmit information. Scientists have discovered that in people with autism, this wiring is faulty, leading to misfiring in communications between brain cells.
In the brain, nerve cells transmit important messages that regulate body functions -- everything from social behavior to movement. Imaging studies have revealed that autistic children have too many nerve fibers, but that they're not working well enough to facilitate communication between the various parts of the brain. Scientists think that all of this extra circuitry may affect brain size. Although autistic children are born with normal or smaller-than-normal brains, they undergo a period of rapid growth between ages 6 and 14 months, so that by about age four, their brains tends to be unusually large for their age. Genetic defects in brain growth factors may lead to this abnormal brain development.
Scientists also have discovered irregularities in the brain structures themselves, such as in the corpus callosum (which facilitates communication between the two hemispheres of the brain),amygdala (which affects emotion and social behavior), and cerebellum (which is involved with motor activity, balance, and coordination). They believe these abnormalities occur during prenatal development.
In addition, scientists have noted imbalances in neurotransmitters -- chemicals that help nerve cells communicate with one another. Two of the neurotransmitters that appear to be affected are serotonin (which affects emotion and behavior) and glutamate (which plays a role in neuron activity). Together, these brain differences may account for autistic behaviors.
Scientists continue to look for clues to the origins of autism. By studying the genetic and environmental factors that may cause the condition, they hope to develop tests to identify autism earlier, as well as new treatment methods.
Several research studies are looking at the link between genes and autism. The largest of these is the National Alliance for Autism Research (NAAR) Autism Genome Project. This collaborative effort, conducted at approximately 50 research institutions in 19 countries, is poring through the 30,000 genes that make up the human genome in a search for the genes that trigger autism.
Other autism studies include:
  • Using animal brain models to study how neurotransmitters are impaired in children with autism
  • Testing a computer-based program that would help autistic children interpret facial expressions
  • Examining brain images to discover which areas are active during the obsessive and repetitive behaviors of autism
  • Continuing to investigate the link between thimerosal and autism
