Though ADHD begins in childhood, it can change in symptom presentation as one ages, or can be undiagnosed until later on. If diagnosed later in life, they did not "just develop" ADHD. Rather, they would have had it since childhood, and it simply went undiagnosed. If diagnosed as an adult, only 5 symptoms of inattention and hyperactivity/impulsivity each need to be applicable, as found in the DSM-5. Like in children, environmental factors or other mental disorders can cause similar symptoms to ADHD, so it is important to rule these possibilities out. A thorough evaluation by a physician is recommended over self-evaluation. 

Some of the more prominent symptoms of ADHD in adulthood include anxiety, disorganization, poor time management, and poor memory. Multi-tasking may be attempted (unsuccessfully). 

ADHD in Adults

There is no singular test to diagnose for ADHD in children. Instead, diagnosis is formulated based on the history of the patient and a discussion of symptoms. A test battery may be utilized to check cognitive functioning. 

The primary problem with diagnosing ADHD in children is that most children are inattentive and squirrely at least at some point in their lives. Level of attention can be affected by level of interest. In order to be diagnosed, the child would have to be struggling with inattention and hyperactivity in more than one area of life., and this struggle cannot be explained by other factors. They also have to display at least 6 symptoms of inattention and at least 6 symptoms of hyperactivity as denoted in the DSM-5. 

ADHD in children

According to the APA, 3-7% of school-age children have ADHD, and many display significant symptoms throughout adolescence. However, there is little known about the symptomology of ADHD in adolescence and adulthood, particularly in college-aged populations. This article is designed to summarize major research findings about ADHD in college-aged populations, including prevalence of symptoms, psychological functioning, and potential influence on academic performance. Findings suggest college students with ADHD are at greater risk for academic and psychological difficulties, but these findings are merely preliminary.

References for "Parents of Children with ADHD"

Parents of children who are diagnosed with ADHD may face unique challenges. There are many factors that contribute to ADHD and its severity. Therefore, considering how parental stress, ADHD tendencies, and home environment play a role is important in diagnosis, treatment, and support for children with ADHD and their caretakers.  

Parental Stress: Higher levels of parental stress and self-stigma has been associated with higher severity of ADHD symptoms in children (Charbonnier et al., 2018; Marumoto et al., 2023; Pardo-Salamanca et al., 2024; Taylor et al., 2018). In addition, parents of children with ADHD were found to have higher levels of stress when compared to parents of children with anxiety disorders (Telman et al., 2017). This parental stress has been correlated with higher rates of bullying in children with ADHD (Taylor et al., 2018).

Parental ADHD Tendencies: Parents who have symptoms of ADHD experience higher levels of stress and children with higher severities of ADHD (Marumoto et al., 2023). 

Home Environment: Chaotic household environments are associated with severity of children’s ADHD symptoms, indicating a gene-environment correlation (Agnew‐Blais et al., 2022).  

Psychotherapy for parents who have children with ADHD should include an encouragement for more social support (Pardo-Salamanca et al., 2024), a discussion of public- and self-stigmas associated with ADHD (Charbonnier et al., 2018) and increasing parent knowledge of the disorder (Taylor et al., 2018).

Attention-Deficit Hyperactivity Disorder (ADHD) is characterized by inattention and hyperactivity-impulsivity and is divided into three subtypes:
- primarily inattentive
- primarily hyperactive-impulsive
- combined

Attention-Deficit Hyperactivity Disorder (ADHD)

Attention deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that has two components: problems with concentration and distractibility (attention), and problems with restlessness and impulse control (hyperactivity).

Attention Deficit/Hyperactivity Disorder (ADHD)

Inattention in children can manifest in bad time management, forgetfulness, disorganization, and task avoidance; while hyperactivity can manifest in ways such as difficulty waiting for their turns, difficulty in being still, excessive physical activities such as running and climibing. 

ADHD in Childhood

The exact causes and triggers for ADHD development are unknown, but there are some speculated risk factors. 

ADHD is NOT caused by excess sugar, poor parenting/schooling, too much TV/video games, stress, or food allergies. These things may make symptoms worse, but they are NOT causes.

ADHD: Prevalence Rates

According to the DSM-V, diagnostic criteria for ADHD is as follows:
- A persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development.
- Several inattentive or hyperactive-impulsive symptoms were present prior to age 12 years.
- Several inattentive or hyperactive-impulsive symptoms are present in two or more settings (e.g., at home, school, etc.)
- There is clear evidence that symptoms interfere with, or reduce the quality of social, academic, or occupational functioning.
- The symptoms do not occur exclusively during the course of schizophrenia or another psychotic disorder, and are not better explained by another mental disorder.

ADHD: Diagnostic Criteria

Symptoms are grouped into 3 types:

- Inattentive: easily distracted, forgetful, daydreams frequently, and disorganized.
- Hyperactive-Impulsive: fidgety, excitable, high-energy, struggles with patience, interrupts others
- Combined: displays a mix of symptoms from the above two types.

Symptoms can change as a person grows and develops, and some even "grow out of their ADHD".  It is possible for symptoms to disappear or resurface during one's lifetime.

Symptoms of ADHD

Those diagnosed with ADHD often find that their ADHD diagnosis impacts the strength and stability of their relationships. Some examples of potentially affected relationships include childhood friendships, familial relationships, romantic partnerships, and relationships with oneself.

Relationships and ADHD

Considering the abundance of pediatric diagnoses, with a large increase since diagnostic changes in the 1980s and changes in Medicare coverage, this disorder's diagnosis has been met with a fair amount of criticism. Particularly regarding pediatric diagnosis, many critics claim ADHD is over-diagnosed, assigning a disability to a child simply being a child and medicating them to enforce compliance. Some critics proclaim this increase in medication of children for ADHD is to push drugs on the population and make a buck. 
Over-prescribing does exist in some areas, however, on the whole, it does not appear to be the case. Not every individual with ADHD is prescribed medication. Just because diagnoses have increased, doesn't mean they're all false positives. Diagnostic criteria has changed as our understanding of the disorder has changed. Though this is still hotly debated, additional research is encouraged to formulate an opinion. 

ADHD Diagnosis Controversies

Though there is no cure, there are treatments to help manage symptoms. There are two types of treatment options for ADHD:

- Behavior Therapy (including parental training).
- Medication.

Like most treatments for mental disorders and psychological issues, the best treatment is often a combination of therapy and medication. 

For children with ADHD younger than 6 years old, parent training in behavior management  is recommended as the first line of treatment, before medication is tried. For children 6 years old and older, it's recommended to try medication and behavior therapy together.

ADHD: Treatment Options

There are three diagnostic types of ADHD:
- Inattentive Type (Formerly known as Attention-Deficit Disorder)
- Hyperactive-Impulsive Type
- Combined Type (exhibits symptoms of both Inattentive type and Hyperactive/Impulsive type)

ADHD: Types

Though there is no cure, there are treatments to help manage symptoms. Like most treatments for mental disorders and psychological issues, the best treatment is often a combination of therapy and medication. For children with ADHD, therapy is often recommended for their parents/guardians so they know how to better handle the symptoms their child manifests. 

Regarding medications, stimulants are the most frequently prescribed. However, other kinds are prescribed, as stimulants don't work for everyone.

- Stimulants
- Non-stimulants
- Anti-depressants

 - Response inhibition and Working memory ("Cool" executive functioning)
 - Delay Aversion ("Hot" executive functioning)
 - Temporal Processing and Cognitive-energetic state

ADHD: Common Psychiatric Comorbidities

In the 1920s, Hans Hoffman provided one of the earliest documented descriptions of symptoms now associated with ADHD. While caring for his son, Hoffman observed behaviors such as a short attention span, difficulty concentrating on schoolwork, and the need for repeated review of simple material to learn it.

Hans Hoffman's Early Observations of ADHD Symptoms

The modern concept of ADHD formed from the realization that hyperactivity (fidgetiness, restlessness, poor impulse control) and inattention (distractibility, concentration issues) were often co-occurring symptoms. This understanding solidified in the 1970s and led to the inclusion of 'attention deficit disorder with and without hyperactivity' in the DSM-III in 1980, establishing the foundation for the current diagnosis.

Evolution of the ADHD Diagnosis in the DSM

For a significant portion of individuals, ADHD is a lifelong condition that persists into adulthood for about 60% of diagnosed children. This persistence is strongly associated with a high rate of other mental health conditions. A study revealed that nearly 81% of adults with persistent ADHD also had at least one comorbid disorder, a rate substantially higher than the 47% found in adults whose childhood ADHD did not persist.

ADHD Persistence and Comorbidity in Adulthood

The significant role of genetics in ADHD is supported by twin and adoption studies. A comprehensive 2009 review by Burt revealed that the median concordance rate for identical twins was .66, substantially higher than the .20 rate for fraternal twins. The same review identified a concordance rate of .09 for unrelated adoptive siblings, suggesting that while genetics are primary, environmental factors may also contribute to the disorder's development.

Evidence for Genetic Influence on ADHD from Twin and Adoption Studies

The heritability of ADHD's core symptoms is estimated to be very high, reinforcing the disorder's strong genetic roots. A 2010 review of studies by Nikolas & Burt found that the heritability of inattention was 71%, while the heritability of hyperactivity was 73%.

Heritability Estimates for Core ADHD Symptoms

Evidence from multiple studies indicates a significant rise in parent-reported ADHD cases in the United States during the 2000s. One study revealed a 22% increase in prevalence among children aged 4-17 between 2003 and 2007, with rates climbing from 7.8% to 9.5%. Another investigation corroborated this trend, showing that for children aged 5-17, the prevalence increased from 6.9% in 1998–2000 to 9.0% in 2007–2009.

ADHD in the United States: Increase in Recent Years

Attention Deficit/Hyperactivity Disorder (ADHD) is defined by a persistent and pervasive pattern of inattention and/or hyperactive and impulsive behaviors that significantly disrupt normal functioning.

Characteristics of ADHD

The development of ADHD is influenced by both genetic and neurobiological factors. This condition can extend into adulthood and is frequently linked with adverse long-term outcomes.

Etiology and Prognosis of ADHD

A teacher reports that a 9-year-old student often loses assignments, has difficulty waiting for their turn in games, and frequently interrupts others. The student's parents mention similar issues at home, noting that the child struggles to complete chores without getting sidetracked and seems to be in constant motion, even during quiet activities. These patterns have been observed consistently for over a year. Analyze this scenario and explain why the combination of these behaviors, their persistence over time, and their presence across different settings are critical factors in distinguishing a potential neurodevelopmental disorder from typical childhood energy.
