These factors include exposure to pollutants, such as plant emissions and mercury, urban versus rural residence, and vitamin D deficiency (Kinney, Barch, Chayka, Napoleon, & Munir, 2009). Most instances of the common communicable diseases, such as measles, chicken pox, and mumps, are encountered in childhood. The inability of infants and small children to swallow pills and capsules necessitates the use of other forms and alternate routes of administration. Finally, the nutritional requirements of the growing child must be considered when treatment of disease requires modification of the diet or administration of drugs that may affect the absorption or metabolism of essential nutrients. The development of psychological and intellectual function is equally complex and requires special understanding. Over time this increase in parent-reported ADHD was observed in all sociodemographic groups and was reflected by substantial increases in 12 states (Indiana, North Carolina, and Colorado were the top three). But one thing is for sure, anxiety is not a death sentence. Notably, the study that fueled the controversy reported that 8 out of 12 children—according to their parents—developed symptoms consistent with autism spectrum disorder shortly after receiving a vaccination. These children do not make eye contact with others and seem to prefer playing alone rather than with others. On the average, boys are 3 times more likely to have ADHD than are girls; however, such findings might reflect the greater propensity of boys to engage in aggressive and antisocial behavior and thus incur a greater likelihood of being referred to psychological clinics (Barkley, 2006). A recent study found that 29.3% of adults who had been diagnosed with ADHD decades earlier still showed symptoms (Barbaresi et al., 2013). Please select which sections you would like to print: While every effort has been made to follow citation style rules, there may be some discrepancies. Recall that one of the functions of the frontal lobes is to inhibit our behavior. Early theories of autism placed the blame squarely on the shoulders of the child’s parents, particularly the mother. Let us know if you have suggestions to improve this article (requires login). However, there is no scientific evidence that a link exists between autism and vaccinations (Hughes, 2007). The child’s behavior is hasty, impulsive, and seems to occur without much forethought; these characteristics may explain why adolescents and young adults diagnosed with ADHD receive more traffic tickets and have more automobile accidents than do others (Thompson, Molina, Pelham, & Gnagy, 2007). In this section, we will discuss two such disorders: attention deficit/ hyperactivity disorder and autism. Corrections? Some individuals with autism spectrum disorder, particularly those with better language and intellectual skills, can live and work independently as adults. The exact causes of autism spectrum disorder remain unknown despite massive research efforts over the last two decades (Meek, Lemery-Chalfant, Jahromi, & Valiente, 2013). Changes in the environment occur as the surroundings and contacts of a totally dependent infant become those of a progressively more independent child and adolescent. Neurodevelopmental disorders are a group of disorders that are typically diagnosed during childhood and are characterized by developmental deficits in personal, social, academic, and intellectual realms; these disorders include attention deficit/hyperactivity disorder (ADHD) and autism spectrum disorder. For example, certain specific disorders, such as precocious puberty, are unique to children; others, such as acute nephritis—inflammation of the kidney—are common in children and infrequent in adults. Currently, estimates indicate that nearly 1 in 88 children in the United States has autism spectrum disorder; the disorder is 5 times more common in boys (1 out of 54) than girls (1 out of 252) (CDC, 2012). It is absolutely possible for a child to overcome it. Modification, adaptation, and original content. In adults, one period may last weeks to years whereas with children an episode may last hours. The enormous volume of electronic information pertaining to autism spectrum disorder, combined with how difficult it can be to grasp complex scientific concepts, can make separating good research from bad challenging (Downs, 2008). How about medical conditions? Compared to children without ADHD, those with ADHD appear to have smaller frontal lobe volume, and they show less frontal lobe activation when performing mental tasks. Nevertheless, the findings from these studies raise important questions concerning what appears to be a demonstrable rise in the prevalence of ADHD. Like adults, children can experience the normal mood many of us refer to … Stress-Related Disorders. Mental health disorders in children are generally defined as delays or disruptions in developing age-appropriate thinking, behaviors, social skills or regulation of emotions. Compared to their non-ADHD counterparts, children with ADHD have lower grades and standardized test scores and higher rates of expulsion, grade retention, and dropping out (Loe & Feldman, 2007). While taking care of his son while his wife was in the hospital giving birth to a second child, Hoffman noticed that the boy had trouble concentrating on his homework, had a short attention span, and had to repeatedly go over easy homework to learn the material (Jellinek & Herzog, 1999). … Autism spectrum disorder is probably the most misunderstood and puzzling of the neurodevelopmental disorders. How to use disorder in a sentence. Diseases of the fetus may derive directly from disorders of the mother or may be caused by drugs administered to her. In the general consideration of childhood diseases, a final aspect that merits emphasis is the role of prevention. One study reported that childhood ADHD predicted later drinking problems, daily smoking, and use of marijuana and other illicit drugs (Molina & Pelham, 2003). Professor of Pediatrics; Senior Associate Dean and Associate Dean for Clinical Affairs, Albert Einstein College of Medicine, Yeshiva University, Bronx, New York. Generally, when we speak about childhood disorders, we are referring to mental and emotional problems that most often occur and are diagnosed when children are school aged or younger. How much do you know about human anatomy? The risk of substance abuse problems appears to be even greater for those with ADHD who also exhibit antisocial tendencies (Marshal & Molina, 2006). Many different genes and gene mutations have been implicated in autism (Meek et al., 2013). common childhood diseases so that actions can be taken to decrease the spread of the illness or infestation to others. Childhood disorders, often labeled as developmental disorders or learning disorders, most often occur and are diagnosed when the child is of school-age. Indeed, a recent study compared the vaccination histories of 256 children with autism spectrum disorder with that of 752 control children across three time periods during their first two years of life (birth to 3 months, birth to 7 months, and birth to 2 years) (DeStefano, Price, & Weintraub, 2013). The brain? Usually, symptoms start during infancy or in early childhood, although some of … The most common childhood mental disorders are anxiety disorders, depression, and attention deficit hyperactivity disorder (). It is a devastating condition of unknown cause. Nearly everyone has heard of ADHD, and most parents and teachers are aware of its key symptoms. Inapparent environmental causes of diseases, such as poisonings, must be considered and investigated thoroughly, by methods that at times resemble those of a detective. Children & neurodevelopmental behavioural intellectual disorders NEURODEVELOPMENTAL BEHAVIORAL INTELLECTUAL DISORDERS Inconsistencies in terminology and definitions European Definition: Neurodevelopmental disorders are disabilities in the functioning of the brain that affect a child’s behaviour, memory or ability to learn Just like adults can have an anxiety disorder, children can also have one. Autism appears to be strongly influenced by genetics, as identical twins show concordance rates of 60%–90%, whereas concordance rates for fraternal twins and siblings are 5%–10% (Autism Genome Project Consortium, 2007). Compared to a control sample of 136 participants who had never been diagnosed with ADHD, those who were diagnosed as children: Longitudinal studies also show that children diagnosed with ADHD are at higher risk for substance abuse problems. Communication deficits can range from a complete lack of speech, to one word responses (e.g., saying “Yes” or “No” when replying to questions or statements that require additional elaboration), to echoed speech (e.g., parroting what another person says, either immediately or several hours or even days later), to difficulty maintaining a conversation because of an inability to reciprocate others’ comments. Why does concern over vaccines and autism spectrum disorder persist? In some cases, the person with autism spectrum disorder might show highly restricted and fixated interests that appear to be abnormal in their intensity. The qualifier “spectrum” in autism spectrum disorder is used to indicate that individuals with the disorder can show a range, or spectrum, of symptoms that vary in their magnitude and severity: some severe, others less severe. Researchers have not … These disorders are usually first diagnosed in infancy, childhood, or adolescence, as laid out in the DSM-IV-TR and in the ICD-10. Thus, it is of no concern if a 12-month-old infant is unable to walk alone, although some infants are able to do so at nine months of age. Despite the retraction, the reporting in popular media led to concerns about a possible link between vaccines and autism persisting. Sometimes I’m Anxious, Volume 1 – (A Child… Children diagnosed with ADHD face considerably worse long-term outcomes than do those children who do not receive such a diagnosis. Of even more importance, however, is the fact that adult norms cannot be applied to younger age groups. The outlook for recovery from diseases in children is often better than it is for adults, since the child’s additional capacity of growth may counteract the adverse influences of disease. For instance, childhood feeding disorders are not discussed within the eating disorders chapter of the DSM, but instead within the "ghetto" of the child disorders chapter. The previous edition of the DSM included a diagnosis of Asperger’s disorder, generally recognized as a less severe form of autistic disorder; individuals diagnosed with Asperger’s disorder were described as having average or high intelligence and a strong vocabulary, but exhibiting impairments in social interaction and social communication, such as talking only about their special interests (Wing, Gould, & Gillberg, 2011). Treatment of childhood disease requires similar considerations with regard to various stages of growth and development. Although the reasons underlying this apparent increase in the rates of ADHD over time are poorly understood and, at best, speculative, several explanations are viable: ADHD may be over-diagnosed by doctors who are too quick to medicate children as a behavior treatment. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. Health and disease during the period from conception to adolescence must be understood against this backdrop of changes. Just as important as the development of public health measures is their practical application; underutilization of established procedures and techniques for prevention of disease is a major health problem. Childhood Disintegrative Disorder (CDD) is among the 5 major types of autistic disorders and is sometimes referred to as Dementia Infantilis or Disintegrative Psychosis. A number of environmental factors are also thought to be associated with increased risk for autism spectrum disorder, at least in part, because they contribute to new mutations. Drug toxicity of importance at one stage of development may be of no concern at another; for example, the commonly used antibiotic tetracycline is best avoided in treatment of the child younger than age 10 because it is deposited in teeth, in which enamel is also being deposited, and stains them. Five-year-old boys average 44 pounds (20 kilograms) in weight but may vary from 33 to 53 pounds (15 to 24 kilograms). Conduct disorder Children with conduct disorder (CD) are often judged as ‘bad kids’ because of their delinquent behaviour and refusal to accept rules. Numerous studies, however, have shown a significant relationship between exposure to nicotine in cigarette smoke during the prenatal period and ADHD (Linnet et al., 2003). Family and twin studies indicate that genetics play a significant role in the development of ADHD. The specific genes involved in ADHD are thought to include at least two that are important in the regulation of the neurotransmitter dopamine (Gizer, Ficks, & Waldman, 2009), suggesting that dopamine may be important in ADHD. Around five per cent of 10 year olds are thought to have CD, with boys outnumbering girls by four to one. People with ADHD show less dopamine activity in key regions of the brain, especially those associated with motivation and reward (Volkow et al., 2009), which provides support to the theory that dopamine deficits may be a vital factor in the development this disorder (Swanson et al., 2007). Chickenpox is one of diseases giving immunity for the rest of our life, which is why just … It involves serious behavior problems that are likely to raise alarm among teachers, parents, peers, and other adults. Among the genes involved are those important in the formation of synaptic circuits that facilitate communication between different areas of the brain (Gauthier et al., 2011). By the 1970s, many had become aware of the connection between nutritional factors and childhood behavior. Thus, abnormalities in this region may go a long way toward explaining the hyperactive, uncontrolled behavior of ADHD. Please refer to the appropriate style manual or other sources if you have any questions. Most of the disorders we have discussed so far are typically diagnosed in adulthood, although they can and sometimes do occur during childhood. Although, for the most part, the diseases of childhood are similar to those of the adult, there are several important differences. Get a Britannica Premium subscription and gain access to exclusive content. (Klein et al., 2012). Finally, a major segment of pediatric care concerns the treatment and prevention of congenital anomalies, both functional and structural. He called this condition early infantile autism, and it was characterized mainly by an inability to form close emotional ties with others, speech and language abnormalities, repetitive behaviors, and an intolerance of minor changes in the environment and in normal routines (Bregman, 2005). Autism spectrum disorder is referred to in everyday language as autism; in fact, the disorder was termed “autistic disorder” in earlier editions of the DSM, and its diagnostic criteria were much narrower than those of autism spectrum disorder. At the time of the study, the children were between 6 and 13 years old, and their prior vaccination records were obtained. Childhood obesity is a serious medical condition that affects children and adolescents. Omissions? The crucial question is at what age one becomes concerned if a developmental milestone has not been reached. Other specialized techniques permit examination of the fetus by X-ray and ultrasound, and by electrocardiography and electroencephalography (methods for observing and recording the electrical activity of the heart and the brain, respectively). The DSM-5 specifies that the symptoms of autism spectrum disorder are not caused or explained by intellectual disability. Child mental problems are described and contained within a single large chapter, and considered separately from adult disorders, even when adult disorders exist, which are similar in nature. ☺ Books to learn more about childhood anxiety . However, most do not because the symptoms remain sufficient to cause serious impairment in many realms of life (APA, 2013). For example, the child might throw a temper tantrum if an object is not in its proper place or if a regularly-scheduled activity is rescheduled. In what must certainly stand as one of the more controversial assertions in psychology over the last 50 years, he wrote, “I state my belief that the precipitating factor in infantile autism is the parent’s wish that his child should not exist” (Bettelheim, 1967, p. 125). Conduct disorder (CD) is an impulse control disorder that usually develops during childhood or adolescence. A mental illness, or mental health disorder, is defined as patterns or changes in thinking, feeling or behaving that cause distress or disrupt a person's ability to function. Editor of, 44 Questions from Britannica’s Most Popular Health and Medicine Quizzes. The bone fracture that results in permanent deformity in the adult, for example, may heal with complete structural normality in the child, as continued growth results in remodeling and reshaping of the bone. Disorders of nutrition, still of great concern, especially but not exclusively in developing countries, are of extreme importance to the growing and developing child. Childhood disease and disorder, any illness, impairment, or abnormal condition that affects primarily infants and children—i.e., those in the age span that begins with the fetus and extends through adolescence. In one investigation, 135 adults who had been identified as having ADHD symptoms in the 1970s were contacted decades later and interviewed (Klein et al., 2012). Socioeconomic factors—such as better maternal nutrition and obstetrical care and improved housing, water supplies, and sewage disposal—have been of prime importance in this decline, together with better hygiene at home, safer infant feeding techniques, and widespread immunization against common infectious diseases. Neurodevelopmental disorders are a group of disorders that are typically diagnosed during childhood and are characterized by developmental deficits in personal, social, academic, and intellectual realms; these disorders include attention deficit/hyperactivity disorder (ADHD) and autism spectrum disorder. In comparison to the favourable effect of these and other preventive measures, an increased capacity to treat diseases, even with such powerful tools as the antibiotic drugs, has had relatively little impact. Infectious disorders are prevalent and remain a leading cause of death, although individual illnesses are often mild and of minor consequence. CDD is considered a low-functioning form of autistic spec… Indeed, medications used in the treatment of ADHD, such as methylphenidate (Ritalin) and amphetamine with dextroamphetamine (Adderall), have stimulant qualities and elevate dopamine activity. Rates of autistic spectrum disorder have increased dramatically since the 1980s. In recognition of such findings, the DSM-III (published in 1980) included a new disorder: attention deficit disorder with and without hyperactivity, now known as attention deficit/hyperactivity disorder (ADHD). Diego is always active, from the time he wakes up in the morning until the time he goes to bed at night. Brain imaging studies have shown that children with ADHD exhibit abnormalities in their frontal lobes, an area in which dopamine is in abundance. The major factors responsible for the decline in infant and childhood mortality rates over the past decades have been the development and application of preventive measures. Instead, parents were simply asked whether or not a doctor or other health-care provider had ever told them their child had ADHD; the reported prevalence rates thus may have been affected by the accuracy of parental memory. However, there are a group of conditions that, when present, are diagnosed early in childhood, often before the time a child enters school. Although it is believed by some that autism is triggered by the MMR vaccination, evidence does not support this claim. These findings were very controversial and drew a great deal of attention, sparking an international forum on whether children should be vaccinated. Older children, especially adolescents, are exposed, as are adults, to environmental hazards that they deliberately seek, such as cigarette smoking and the use of alcohol and other drugs. The converse may also be true, however. Additionally, as was the case with diet and ADHD in the 1970s, the notion that autism spectrum disorder is caused by vaccinations is appealing to some because it provides a simple explanation for this condition. At the same time, some diseases that are common in adults are infrequent in children. Since the various periods of growth and development differ so markedly from one another, they are divided for convenience into the following stages: intrauterine (the period before birth), neonatal (first four weeks), infant (first year), preschool (one to five years), early school (six to 10 years for girls, six to 12 for boys), prepubescent (10 to 12 for girls, 12 to 14 for boys), and adolescent (12 to 18 for girls, 14 to 20 for boys). For children with speech disorders, it can be tough forming the sounds that make up speech or putting sentences together. Parents and caregivers who would like more information regarding the illnesses and infestations described in this guide or information on how to care for their sick child can A seminal paper published in 1943 by psychiatrist Leo Kanner described an unusual neurodevelopmental condition he observed in a group of children. In contrast, removal of one kidney in the adult usually results in a residual functional capacity equal to 70 to 75 percent of that of two normal kidneys. Here is an instructive and poignant video highlighting severe autism. This article reviews the scope of diseases that affect children, with particular emphasis on the ways in which the unique attributes of the growing child and special aspects of his environment serve to modify the course, effects, and treatment of particular diseases.
