Is ADHD Considered a Developmental Disability?

Most cases of ADHD (attention deficit hyperactivity disorder) present themselves in preschool or kindergarten. Problems in a child's social life, academic achievement, and family connections can stem from his or her attention deficit hyperactivity disorder (ADHD), whose symptoms include impulsivity and hyperactivity.

Every single kid shows signs of ADHD. Due to their youthful enthusiasm and general restlessness, children tend to be restless and quickly sidetracked.

Many children who display disruptive behaviour or who have difficulties focusing may not actually have ADHD or may have a milder form of the illness. Differentiating between common behavioural problems and the treatable indicators of attention deficit hyperactivity disorder is a challenge for parents and professionals (ADHD).

The causes of the increasing number of ADHD diagnosis are unknown. Even still, progress in name recognition may explain some of the expansion. It's crucial to conduct a thorough evaluation of young children who exhibit symptoms of attention deficit hyperactivity disorder (ADHD) because these symptoms can be caused by a variety of different behavioural and developmental issues. Lack of focus, impulse control, or hyperactivity in children may also be the result of underlying health conditions, emotional difficulties, educational challenges, or just a lack of sleep.

The criteria for diagnosing attention deficit hyperactivity disorder are stringent. In order to diagnose your child with Attention Deficit Hyperactivity Disorder (ADHD), they must exhibit six or more symptoms for at least six months, all of which are having a significant negative effect on their day-to-day functioning.

Medications exist for the treatment of ADHD. Medicine, constructive parenting techniques, and psychiatric and behavioural therapy are also effective. An effective treatment plan for children with attention deficit hyperactivity disorder (ADHD) should involve the participation of parents, teachers, and doctors to assist these kids improve their concentration and behaviour. Most children who are diagnosed with attention deficit hyperactivity disorder go on to achieve great things in life.

What Exactly Is Attention Deficit Hyperactivity Disorder (ADHD)?

Attention deficit hyperactivity disorder (ADHD) is one example of a neurodevelopmental disorder, which includes problems with the formation and maturation of the nervous system. Individuals with ADHD have difficulty maintaining objectivity and self-control.

However, occasionally symptoms of attention deficit hyperactivity disorder (ADHD) don't show up until a child is older and is confronted with more stressful academic and social circumstances.

Children with ADHD are more prone to encounter the following:

• anxiety disorders
• learning disorders
• depression
• a wide range of behavioural issues, including defiance and oppositional.

Adults with a history of childhood ADHD are more likely to experience a variety of mental health issues, some of which have the potential to have a deleterious effect on the educational, occupational, and interpersonal outcomes of those affected. This emphasises the importance of early diagnosis and treatment.

Distinct ADHD Subtypes

A child's ADHD symptoms might manifest in one of three ways:

Predominantly inattentive

Children with this form of ADHD have trouble focusing for long periods of time, which makes it challenging for them to do things like schoolwork.

Predominantly hyperactive/impulsive: 

These children, who tend to be young boys, show impulsive behaviours and difficulty sitting still because of their ADHD. They might fidget, interrupt constantly, and steal things from other people's hands. They are more vulnerable to harm than other children due to their lack of self-control. While symptoms of hyperactivity usually subside by age, problems with impulsive behaviour and inattention can persist well into adulthood.

Combined: 

ADHD is characterised by a number of behavioural issues in children, including impulsivity, hyperactivity, and inattention or distractibility. This is a common symptom in children who suffer from ADHD.

Some children with ADHD may be able to operate properly with only a small amount of medication, while others may need significantly more.

Boys are nearly three times as likely to be diagnosed with ADHD than girls. Boys are more likely to be diagnosed with ADHD than girls because of their hyperactive behaviour.

Girls with ADHD are more likely than boys to have problems concentrating and paying attention. Many people don't get diagnosed and start treatment for this form of ADHD until they're in middle school or high school because it's less severe than other forms.

ADHD Signs and Symptoms

The incidence is youngest among those under the age of four and never later than the twelfth year. Those with the predominantly inattentive form are often not diagnosed until well into adulthood, while those diagnosed between the ages of 8 and 10 have a higher prevalence. Among the many symptoms associated with ADHD are:

• Impulsivity
• Inattention
• Hyperactivity

When asked to engage in tasks that require focus, concentration, speed of response, visual and perceptual search, or systematic, lengthy listening, certain children may struggle.

The term "impulsivity" is used to characterise the propensity to act without considering the potential outcomes of one's actions, such as when a child darts across the street without looking or when a teenager or adult decides to drop out of school or a job without giving it any thought.

The symptoms of hyperactivity are a lack of self-control and a rapid succession of actions. In particular, younger children may struggle to maintain the appropriate level of silence in formal settings like those found in educational institutions and religious institutions. Observing older patients can be taxing because they are frequently active, fidgety, or chatty.

When one struggles with inattention or impulsivity, it can be challenging to learn new knowledge, remember it, apply it, and do well in school and in life. Because they have trouble focusing, children with inattentive ADD do poorly in dynamic classroom settings.

The percentage of children with ADHD who also struggle academically ranges from 20% to 60%. Despite this, most children with ADHD struggle in school due to inattention that causes them to overlook information and impulsivity that causes them to answer questions without fully considering their answers.

Looking at a person's behaviour history can reveal issues such as a lack of social skills and interactions with peers, sleep problems, anxiety, dysphoria, depression, and irritability.

Although there are no objective physical examination or laboratory findings connected to attention deficit hyperactivity disorder (ADHD), the following may be present:

• Lack of motor control or coordination
• Soft, nonspecific neurologic findings
• Perceptual-motor dysfunctions

Causes of ADHD

Researchers are looking into the origins of ADHD in an effort to develop more effective treatments and preventative measures. Despite the lack of knowledge on what exactly causes or contributes to ADHD, recent studies have revealed the significant impact that genetics plays in the development of the disorder. Recent twin studies have discovered a genetic relationship between the disorders.

Genetics is just one of several potential causes and risk factors that researchers are looking into:

• Brain injury
• Exposure to environmental (e.g., lead) during pregnancy or at a young age
• Alcohol and tobacco use during pregnancy
• Premature delivery
• Low birth weight

The widely held beliefs that ADHD is brought on by excessive sugar intake, excessive television viewing, poor parenting, or societal and environmental variables like poverty or family upheaval are unfounded, according to scientific studies. Symptoms could be exacerbated by several factors, including these. However, there is not enough proof to say that they are the primary causes of ADHD.

Diagnosis

The American Academy of Pediatrics has published a clinical practise guideline for the diagnosis, evaluation, and management of attention-deficit/hyperactivity disorder in children and adolescents, which can be consulted for more information.

DSM-5 diagnostic criteria for ADHD

According to DSM-5, there are nine symptoms and indicators for inattention, and nine for hyperactivity and impulsivity. Using these criteria, a diagnosis requires the presence of six symptoms and signs, with at least two from each category. Furthermore, the symptoms must

• Maintain a regular presence for at least a half a year.
• Have a greater impact than would be expected given the child's age.
• Appear in a minimum of two settings, such as a child's household and a school
• Be present before age 12 (at least some symptoms)
• Interfere with functioning at home, school, or work

Inattention symptoms:

• Pays no attention to details or makes careless errors in schoolwork or other activities
• Has trouble sustaining attention on tasks at school or at play
• When spoken to directly, he does not appear to listen.
• Does not carry out instructions or complete tasks
• Has trouble organising tasks and activities
• Avoids or is hesitant to engage in tasks that require sustained mental effort over an extended period of time.
• Frequently misplaces items required for school tasks or activities
• Is prone to distraction
• Is prone to forgetting routine tasks

Hyperactivity and impulsivity symptoms:

• Frequently shifts their weight from one foot to another, or fidgets with their hands.
• Constantly gets up from their seats, whether in class or elsewhere
• Frequently engages in unnecessary bouncing about or climbing
• Plays loudly and obnoxiously
• Constant motion; constantly behaving as if propelled by an engine
• Often talks excessively
• Responds abruptly to questions, sometimes even before they're finished being asked.
• Has a hard time sitting and waiting for his or her turn
• Interjects or interrupts frequently

Predominantly inattentive types can be diagnosed by looking for a set of six symptoms and evidence of indiscipline. Symptoms and indicators of hyperactivity and impulsivity must be present in six individuals for a diagnosis of the hyperactive/impulsive type to be made. Six symptoms and indicators of inattention and six of hyperactivity/impulsivity are needed to make a diagnosis of the mixed kind.

Other diagnostic considerations

Differentiating ADHD from other conditions might be difficult. Overdiagnosis is a problem that needs to be solved, and it's important to get the right diagnosis the first time around. Many of the symptoms of attention deficit hyperactivity disorder (ADHD) in young children may also be indicative of difficulties in communicating due to other neurodevelopmental disorders (such as autism spectrum disorders) or certain learning disorders, anxiety disorders, depression, or behavioural disorders (e.g., conduct disorder).

When diagnosing a child with attention issues, clinicians need to think about whether the child's distractions are coming from within or from the outside world (i.e., thoughts, anxieties, worries). In contrast, the symptoms of attention deficit hyperactivity disorder (ADHD) become more qualitatively distinct as children get older; children with the hyperactive/impulsive type or combined type often display persistent movement of the lower extremities, motor persistence (e.g., purposeless movement, fidgeting of hands), impulsive talking, and an apparent lack of awareness of their environment. Oftentimes, children who suffer from the inattentive subtype show no outward symptoms.

The goal of a medical evaluation is to locate underlying causes for the patient's symptoms and indicators that can be remedied. Prenatal exposures (such as drugs, alcohol, and tobacco) should be asked about, as should perinatal complications or infections, central nervous system infections, traumatic brain injury, heart disease, sleep-disordered breathing, poor appetite, picky eating, and a family history of attention deficit hyperactivity disorder.

When conducting a developmental evaluation, the primary goal is to trace the history of symptoms and indications. Using rating scales designed specifically for attention deficit hyperactivity disorder (ADHD), as well as marking off a list of developmental milestones, particularly language milestones, helps with the assessment (e.g., the Vanderbilt Assessment Scale, the Conners Comprehensive Behavior Rating Scale, the ADHD Rating Scale-V). There are versions of these tests for both parents and teachers, allowing for comprehensive evaluation in accordance with DSM-5 standards. It is important to remember that a diagnosis cannot be made only using scales.

Documenting the most important symptoms and indicators is the primary goal of educational evaluation, which may involve looking over previous grades or utilising rating scales and checklists. It is not always possible to tell ADHD apart from other developmental disorders or behavioural disorders using only rating scales and checklists.

Prognosis

Children with ADHD is untreated or poorly managed often see an exacerbation of their symptoms in the typical classroom setting and during academic pursuits. Problems with social and emotional adjustment may be long-lasting. Loneliness and social isolation are worse as people become older and their symptoms become more noticeable. Many adults and adolescents with attention deficit hyperactivity disorder (ADHD) self-medicate with both legal (e.g., caffeine) and illegal (e.g., cocaine) medications, thus it's important to recognise and treat this condition.

Hyperactivity symptoms and indicators often decrease with age, however some challenges may persist even in teenagers and adults. There are a number of factors that can foretell negative results in later life, particularly in adolescents and adults.

• Coexisting low intelligence
• Aggressiveness
• Social and interpersonal problems
• Parental psychopathology

Academic failure, low self-esteem, and trouble learning acceptable social behaviour are the most common symptoms of problems in adolescence and adulthood. Many people with a history of impulsive-dominant ADHD continue to show symptoms such as agitation, hyperactivity, and a lack of social skills well into adulthood. Those who suffer from attention deficit hyperactivity disorder (ADHD) may find more success in the workplace than in school or at home.

Treatment

• Behavioural therapy
• Drug therapy, typically with stimulants such as methylphenidate or dextroamphetamine (in short- and long-acting preparations)

Behavioral or combination therapy is indicated for younger children, although behavioural therapy alone is less successful than therapy with stimulant medicines alone for school-aged children, according to randomised, controlled research. Despite the fact that medication therapy does not change the underlying neurophysiologic abnormalities of people with ADHD, it is beneficial in reducing ADHD symptoms and allowing participation in activities that were previously unattainable due to poor attention and impulsivity. Substance abuse can break the pattern of negative behaviour, which can then be treated with positive reinforcement, academic and behavioural interventions, and improved self-esteem.

Adults with ADHD receive treatment in a similar fashion, although their medicine of choice and dosage will be dictated by their specific circumstances.

Stimulant drugs

Methylphenidate and amphetamine salts are the most often used stimulant formulations. There is a wide range of responses possible, and the optimal dosage is determined by the severity of the child's behaviour and his or her tolerance for the medication. Dosing is modified in both frequency and total amount until the desired response and tolerable adverse effects are reached.

In most cases, clinicians will try to employ morning and midday dosing, with methylphenidate doses starting at 0.3 mg/kg orally once a day (immediate-release form) and increasing in frequency monthly. It is possible to increase the dosage if the medicine is well tolerated but not producing an appropriate response. In most children, an individual dose between 0.3 and 0.6 mg/kg provides the best compromise between benefits and bad effects. Methylphenidate's dextro isomer, which contains the active component, is half as potent but is also available via prescription.

Initially, 0.15–0.2 mg/kg orally once daily of dextroamphetamine (frequently in combination with racemic amphetamine) is recommended; this dose can be increased to 0.15–0.2 mg/kg orally twice daily or once every four hours while awake. Effective single doses typically fall between 0.15 and 0.4 mg/kg. Effectiveness and safety must be considered during the titration process; while exact amounts will vary greatly between individuals, increasing the chance of undesirable side effects is a common trend at higher doses. Average dextroamphetamine dosages are roughly one-third that of methylphenidate.

Once an appropriate dosage of methylphenidate or dextroamphetamine is attained, the same medicine in a sustained-release version is commonly substituted to prevent drug administration at school. There are a variety of long-acting preparations available, such as biphasic capsules delivering the equivalent of 2 dosages, osmotic release pills, and transdermal patches that can last for up to 12 hours. Now you can choose between fast-acting and slow-acting liquid forms of your medication. To reduce the risk of side effects like anxiety, doctors will sometimes prescribe pure dextro formulations (such dexmethylphenidate) at half the usual dose. For the same reasons (smoother release, longer duration of action, fewer side effects, and lower misuse potential), prodrug formulations are occasionally utilised. While low dosages can promote learning, greater doses are typically necessary to see an effect on behaviour.

Stimulant medications have flexible dosing schedules that can accommodate a wide range of daily and hourly intervals (e.g., during school hours, while doing homework). Weekends, holidays, and summer breaks are ideal times to experiment with drug-free lifestyles. It is recommended that 5- to 10-day placebo periods be conducted at school to assess the continued necessity of the medications.

Common adverse effects of stimulant drugs include:

• Sleep disturbances (e.g., insomnia)
• Depression
• Headache
• Stomachache
• Appetite suppression
• Elevated heart rate and blood pressure

Over two years of stimulant drug use has been linked to a slowdown in growth in certain studies, but the results have been inconsistent, and it is unclear if this effect persists with longer usage. For patients who are especially sensitive to the effects of stimulant drugs, which might cause them to appear either hyperfocused or uninterested, lowering the dosage or switching to a different medicine may be beneficial.

Non-stimulant drugs

Selective norepinephrine reuptake inhibitors like atomoxetine are also used. The drug works, however there is conflicting evidence about how well it works in comparison to stimulant medications. Rarely, liver damage and suicidal ideation occur, and some youngsters experience nausea, drowsiness, irritability, and temper tantrums. Starting at 0.5 mg/kg orally once daily and increasing by 0.5 mg/kg per week up to 1.2 to 1.4 mg/kg once daily is normal. Due to its extended half-life, it can be dosed once day, but it must be taken regularly in order to be effective. Daily maximum dose is 100 mg.

In circumstances where stimulant medicines are either ineffective or have intolerable side effects, other psychoactive drugs, including antidepressants like bupropion and alpha-2 agonists like clonidine and guanfacine, may be utilised. Nonetheless, they are not as effective and should not be used initially. These medicines are sometimes used with stimulants for synergistic benefits; careful monitoring for unwanted effects is required.

Treating ADHD might be complicated by the possibility of negative medication interactions. Some SSRIs, which are also sometimes used in people with ADHD, suppress the metabolic enzyme CYP2D6, which can boost the action of stimulant medicines. An integral element of the pharmacologic care of ADHD patients is the review of potential drug interactions (usually via a computerised tool).

Behavioural Management

Counseling, especially cognitive-behavioral therapy (such as goal-setting, self-monitoring, modelling, and role-playing), can be helpful in teaching children about ADHD and developing strategies for living with the disorder. Regularity and consistency are fundamental.

Noise and visual stimulus reduction, work length, novelty, coaching, and instructor closeness are all proven methods for enhancing student behaviour in the classroom.

When problems at home persist, parents should be encouraged to look for outside help and specialised training in behavioural management strategies. Incentives and token prizes are easy ways to promote positive behaviour change. Children with ADHD whose symptoms are primarily characterised by hyperactivity and a lack of impulse control can benefit from the establishment of routines, rules, and consequences at home.

The least reliable results have been shown with elimination diets, megavitamin therapies, the use of antioxidants or other substances, and dietary and biochemical interventions. While there is some evidence that biofeedback can help in certain situations, there is not enough to recommend using it on a regular basis.

Adults with ADHD may have trouble focusing for extended periods of time, become easily sidetracked, or act or speak without fully considering the consequences of their actions. While any of us can run across these challenges now and again, those with ADHD face them on a daily basis, and they can have a profound impact on their academic, occupational, and social life.

It's estimated that between 2 and 3 percent of adults have been diagnosed with ADHD. 2 While most kids outgrow their ADHD as they become older, about 15% still struggle with it into adulthood.

The specifics of each patient's care plan will determine how they are approached. A variety of psychological treatments are often effective for those with mild ADHD who do not have any other developmental or mental health difficulties. People who have more severe symptoms or other mental health difficulties often benefit from a mix of medicines and psychological treatment.
