ADHD Across the Lifespan: Signs in Children and Adults
At Hoover, we often meet parents who are trying to understand attention-deficit/hyperactivity disorder (ADHD) - both in their children and sometimes in themselves – as it often accompanies dyslexia and other reading disabilities. ADHD is a neurodevelopmental condition that can affect focus, impulse control, and activity levels, but its presentation can vary dramatically between childhood and adulthood. As an adult with ADHD myself, I'd like to walk through how this may appear at different life stages and then also offer local resources for extended professional help.
ADHD in Children
Children with ADHD may show symptoms in three primary categories:
Inattention
Difficulty maintaining focus during schoolwork or play
Frequent careless mistakes in assignments
Appearing not to listen when spoken to directly
Struggling to follow through on instructions
Difficulty organizing tasks and activities
Losing necessary items like school materials, toys, or clothing
Being easily distracted by unrelated stimuli
Forgetfulness in daily activities
Hyperactivity
Frequent fidgeting, tapping, or squirming
Difficulty remaining seated when expected
Running or climbing excessively in inappropriate situations
Inability to play quietly
Often described as "constantly on the go" or "driven by a motor"
Talking excessively
Impulsivity
Blurting out answers before questions are completed
Difficulty waiting for turns
Frequently interrupting or intruding on others' conversations or games
What's important to understand is that not all children will show all symptoms, and ADHD can present primarily as inattentive, primarily hyperactive-impulsive, or as a combined type.
ADHD in Adults
For adults with ADHD, symptoms may manifest differently:
Inattention
Overlooking details in work projects
Difficulty sustaining attention during lengthy meetings or while reading
Struggling to complete long-term projects
Problems with time management and chronic lateness
Difficulty organizing workspaces, homes, or financial records
Frequently misplacing important items like keys, wallets, or phones
Being easily derailed by email notifications or office distractions
Hyperactivity
Internal restlessness or feeling "on edge"
Choosing active, high-intensity jobs
Working multiple jobs or overscheduling
Talking excessively in social or professional settings
Difficulty sitting through movies or long events
Fidgeting during meetings or while watching TV
Impulsivity
Making important decisions without considering long-term consequences
Interrupting during meetings or conversations
Impulsive spending or financial decisions
Changing jobs frequently
Relationship difficulties due to speaking without thinking
Emotional Dysregulation: Anger, Irritability, and Aggression in ADHD
While not always included in certain diagnostics, emotional dysregulation is increasingly recognized as a feature of ADHD in both children and adults. This important aspect can significantly impact daily functioning and relationships.
In Children, symptoms may manifest in the following ways:
Quick to frustration when tasks become challenging
Meltdowns or tantrums that seem disproportionate to the situation
Difficulty calming down after becoming upset
Low frustration tolerance, especially during transitions or when plans change
Explosive reactions when overstimulated or overwhelmed
"Jekyll and Hyde" behavior patterns that confuse parents and teachers
Aggressive responses when feeling criticized or misunderstood
Mood swings that appear to come "out of nowhere"
In Adults, the following symptoms may be present:
Becoming disproportionately irritable when interrupted or when plans change
Difficulty managing frustration in high-demand situations
Quick to anger, especially in situations requiring sustained attention
Overreacting to minor inconveniences or perceived slights
Road rage or heightened irritability while driving
Strained relationships due to emotional volatility
Difficulty de-escalating once agitated
Self-directed anger and harsh self-criticism when making ADHD-related mistakes
Supporting Emotional Regulation
For parents supporting children with ADHD-related emotional challenges, here are a few suggestions for support:
Name and validate emotions before problem-solving
Teach emotional vocabulary and identification
Create calm-down spaces and routines before meltdowns occur
Maintain predictable routines and prepare for transitions
Use visual supports for emotional regulation strategies
Consider that behavior is communication—look for underlying triggers
Remember that emotional control develops later in children with ADHD
Key Differences Between Child and Adult Presentation
When Parents Recognize Themselves in Their Child's Diagnosis
Many parents experience a moment of recognition during their child's evaluation process. If you find yourself in this situation, know that this recognition can be valuable for both you and your child.
Understanding your own ADHD can help you:
Develop more empathy for your child's challenges
Share effective coping strategies you've developed
Consider whether treatment might benefit you as well
Break intergenerational patterns of misunderstanding
Final Thoughts
ADHD is not simply about being unable to pay attention—it's a complex neurobiological condition affecting executive functions like planning, organization, emotional regulation, and time management. Whether in children or adults, early identification and appropriate support can make a tremendous difference.
If you recognize these signs in your child or yourself, consider seeking an evaluation from a qualified healthcare provider. While pediatricians can diagnose, it may be helpful to receive an evaluation from a clinical psychologist or child psychiatrist who specializes in ADHD. Effective treatments exist, from behavioral strategies, appropriate therapy, to medication, and finding the right approach can significantly improve quality of life at any age.
Remember that ADHD also brings strengths—creativity, problem-solving abilities, and high energy levels that, when properly channeled, can be tremendous assets.
