ADHD Symptoms In Toddlers, Children, Adolescents and Adults

ADHD, or Attention-Deficit/Hyperactivity Disorder, is a neurodevelopmental disorder characterised by persistent patterns of inattention, hyperactivity, and impulsivity that can impact daily functioning. Recognizing and understanding the symptoms of ADHD is crucial for early intervention and effective management. In this guide, we'll explore the common symptoms of ADHD, its impacts, and strategies for coping and managing the disorder.

Types of ADHD

A Lifespan Approach: ADHD Symptoms in Toddlers, Children, Adolescents and Adults

ADHD, or Attention-Deficit/Hyperactivity Disorder, is typically classified into three subtypes based on the predominant symptoms:

  1. Predominantly Inattentive Presentation (ADHD-PI): Individuals with this subtype primarily have symptoms of inattention. They may have difficulty sustaining attention, following through on tasks, and organising activities. They may also be easily distracted and forgetful in daily activities.

  2. Predominantly Hyperactive-Impulsive Presentation (ADHD-PH): Individuals with this subtype primarily have symptoms of hyperactivity and impulsivity. They may fidget or squirm in their seats, have difficulty staying seated, and often feel restless. They may also exhibit impulsive behaviours, such as blurting out answers, interrupting others, and acting without thinking.

  3. Combined Presentation (ADHD-C): This is the most common subtype, where individuals exhibit both inattentive and hyperactive-impulsive symptoms. They may have difficulty focusing, be hyperactive, and exhibit impulsive behaviours.

Common symptoms

The symptoms of ADHD can vary widely from person to person and may change over time. Here are some common symptoms associated with ADHD:

Inattention symptoms:

  • Difficulty paying attention to details
  • Trouble staying focused on tasks or activities
  • Easily distracted 

Hyperactivity symptoms:

  • Forgetfulness in daily activities
  • Fidgeting or squirming
  • Difficulty staying seated
  • Excessive talking or interrupting others
  • Always on the go

Impulsivity symptoms:

    • Impatient waiting for their turn
    • Blurting out answers before questions are completed
    • Difficulty following instructions or finishing task

    ADHD symptoms in Toddlers 

    A Lifespan Approach: ADHD Symptoms in Toddlers, Children, Adolescents and Adults

    While ADHD is often diagnosed in school-aged children, symptoms can be noticeable in toddlers as well. According to a study published in the Journal of Attention Disorders, early signs of ADHD can be observed in toddlers as young as 12 to 24 months old. It's important to note that toddlers naturally have high levels of energy and can be easily distracted, so it's crucial to look for persistent patterns of behaviour that go beyond typical toddler behaviour.

    Here are some common ADHD symptoms that may be observed in toddlers:

    1. Inattention: Toddlers with ADHD may have difficulty focusing on tasks or activities, such as playing with toys or listening to a story. They may seem easily distracted and frequently switch from one activity to another.

    2. Hyperactivity: Hyperactivity in toddlers with ADHD may be observed as constant movement, such as running, climbing, or jumping excessively, even in situations where it's not appropriate. They may also have difficulty sitting still, such as during meal times or story time.

    3. Impulsivity: Impulsivity in toddlers with ADHD may be seen as acting without thinking, such as grabbing toys from other children without asking or running into dangerous situations without considering the consequences.

    4. Frequent Tantrums: Toddlers with ADHD may have more frequent and intense tantrums compared to other children their age. These tantrums may be triggered by frustration due to their difficulties with attention and impulse control.

    5. Difficulty Following Instructions: Toddlers with ADHD may have trouble following simple instructions or rules. They may seem to ignore or forget what they were told, leading to frustration for both the child and caregiver.

    6. Sleep Problems: Some toddlers with ADHD may have difficulty settling down at bedtime and staying asleep throughout the night. This can contribute to daytime irritability and difficulty focusing.

    ADHD symptoms in Children

    ADHD can affect children's behaviour and academic performance. According to the Centres for Disease Control and Prevention (CDC), ADHD is one of the most common neurodevelopmental disorders in childhood, affecting about 9.4% of children aged 2-17 years. While symptoms can vary, they generally fall into two categories: inattention and hyperactivity-impulsivity. Here are some common symptoms of ADHD in children:

    Inattention:

    • Difficulty paying attention to details or making careless mistakes in schoolwork or other activities.
    • Trouble staying focused on tasks or play activities.
    • Often seeming not to listen when spoken to directly.
    • Difficulty following through on instructions and failing to finish tasks, such as homework or chores.
    • Avoiding or disliking tasks that require sustained mental effort, such as schoolwork or homework.
    • Losing things necessary for tasks and activities, such as school supplies, toys, or books.
    • Being easily distracted by unrelated thoughts or stimuli.

    Hyperactivity-Impulsivity:

    • Fidgeting or squirming in their seats.
    • Often leaving their seat in situations where sitting is expected, such as in the classroom or during meals.
    • Running or climbing in situations where it is inappropriate or feeling restless.
    • Being unable to play or engage in leisure activities quietly.
    • Talking excessively.
    • Blurting out answers before questions have been completed.

      It's important to note that these symptoms can vary in severity and may not be present all the time. Additionally, some children with ADHD may primarily exhibit symptoms of inattention, while others may primarily exhibit symptoms of hyperactivity-impulsivity.
