ADHD – Attention Deficit Hyperactivity Disorder: Differences in Manifestation Between Children and Adults

ADHD (Attention Deficit Hyperactivity Disorder) is one of the most commonly diagnosed neuropsychiatric disorders in both children and adults. To diagnose ADHD, symptoms must be present during childhood – the condition does not suddenly appear in adulthood. However, symptoms of ADHD can be overlooked in early stages of life, leading to a diagnosis later in adulthood. In some cases, people may experience symptoms resembling ADHD, such as impulsivity, but these may stem from past traumas, particularly those related to interpersonal relationships.


ADHD is characterized by three main groups of symptoms: inattentiveness, impulsivity, and hyperactivity. Modern research shows that ADHD can persist into adulthood, though its manifestation may change over time. It’s also important to consider gender differences in ADHD, as they affect not only the presentation of symptoms but also diagnosis and treatment.


1. ADHD in Childhood – Differences Between Boys and Girls


1.1. ADHD in Boys


Boys make up the majority of ADHD diagnoses in children. ADHD in boys typically presents as the hyperactive-impulsive subtype, with common symptoms such as:


  • Excessive physical activity – Boys often display intense physical restlessness, which may manifest as running, climbing, or struggling to sit still, even in situations where calm is required, such as in school (American Psychiatric Association, 2013).


  • Impulsivity – Boys may struggle with thinking through the consequences of their actions, often interrupting conversations or answering before a question is fully asked (Biederman et al., 2002).


  • Inattentiveness – Boys frequently experience difficulty concentrating, easily becoming distracted or switching between tasks (Hinshaw, 2003).


The visible symptoms of ADHD in boys are often quickly noticed by teachers and parents, leading to earlier diagnosis (Gershon & Gershon, 2002).


1.2. ADHD in Girls


ADHD symptoms in girls may be less noticeable, often resulting in underdiagnosis. Girls are more likely to present with the inattentive subtype. Common symptoms in girls include:


  • Difficulty concentrating – Girls may appear “daydreamy,” struggle to focus, and have issues with organization, often forgetting tasks (Quinn & Madhoo, 2014).


  • Lower physical impulsivity and hyperactivity – Instead of overt physical restlessness, girls may exhibit mental hyperactivity, such as rapidly jumping between thoughts (Rucklidge, 2010).


  • Social withdrawal – Girls may withdraw from social interactions, which can mask their ADHD symptoms (Gershon, 2002).


For this reason, ADHD in girls is often diagnosed later in life when academic struggles become more evident.

2. ADHD in Adults – Differences Between Men and Women


2.1. ADHD in Men


In adult men, ADHD often manifests similarly to how it did in childhood, though symptoms may evolve. Typical symptoms include:


  • Impulsivity – Men with ADHD frequently make hasty decisions without fully considering the consequences (Barkley, 2008).


  • Time management issues – Men with ADHD often struggle with organization and punctuality, which can create difficulties in their professional lives (Kooij et al., 2010).


  • Mental hyperactivity – While physical hyperactivity may decrease, mental restlessness persists (Biederman et al., 2012).


  • Job instability – Men with ADHD may frequently change career paths due to difficulties with focus and organization (Barkley, 2015).


2.2. ADHD in Women


Women are often diagnosed with ADHD later in life because their symptoms tend to be less visible, and many use organizational tools to cope. Common symptoms include:


  • Feeling overwhelmed – Women with ADHD often feel chronically overwhelmed by their responsibilities (Nadeau et al., 2005).


  • Organizational challenges – Despite using tools to stay organized, women with ADHD may still struggle with daily chaos (Quinn, 2013).


  • Overthinking and anxiety – Women tend to worry excessively, which can make decision-making difficult (Rucklidge & Kaplan, 2014).


  • Fatigue and burnout – Chronic stress related to ADHD can lead to exhaustion and burnout (Nadeau, 2012).

Interesting Facts About ADHD and Sleep:


1. Sleep disorders are common among people with ADHD – Many children and teenagers with ADHD struggle with falling asleep, interrupted sleep, and difficulty waking up in the morning. Dysregulation of circadian rhythms can exacerbate these sleep issues.

2. A consistent bedtime routine improves sleep quality – Maintaining a regular bedtime and wake-up schedule can positively impact sleep quality and reduce ADHD symptoms. Even small changes, such as setting a fixed routine, can make noticeable improvements.

3. Cognitive Behavioral Therapy for Insomnia (CBTI) – CBTI is an effective treatment for sleep issues, especially for individuals with ADHD. This therapy teaches techniques to manage thoughts and behaviors that hinder falling asleep.

4. Better sleep enhances focus and behavior – Improving sleep quality, especially by regulating the body’s circadian rhythms, can significantly enhance cognitive functions and behavior in children and adolescents with ADHD.


4. Conclusion


ADHD is a complex disorder, with symptoms varying depending on age and gender. Boys tend to display hyperactive and impulsive behaviors, leading to earlier diagnosis, while girls’ symptoms often go unnoticed. In adulthood, men struggle primarily with impulsivity and work-related issues, while women face organizational challenges and chronic stress. Addressing sleep issues is also an essential part of managing ADHD, as sleep disorders can exacerbate symptoms. Understanding these differences is crucial for effective diagnosis and treatment.
