What to know about ADHD

ADHD stands for attention-deficit/hyperactivity disorder. People with ADHD report difficulties with focusing, restlessness, and impulsivity that affect daily life.

ADHD is relatively common, and it is treatable. Recognizing symptoms and getting an evaluation is the first step to finding effective treatment and support.

What are the symptoms of ADHD?

ADHD affects a person’s ability to manage their thoughts and behavior. There are three main groups of symptoms:

Inattentive type

Inattentive type ADHD is characterized by challenges with focus, organization, and staying on task.

Symptoms can include:

  • Trouble paying attention
  • Difficulty focusing on longer tasks
  • Easily distracted
  • Daily forgetfulness
  • Disorganization
  • Trouble listening
  • Inability to finish tasks
  • Reluctance to engage in hard tasks

Hyperactive/impulse type

Hyperactive/impulsive type ADHD is characterized by excessive movement, restlessness, and challenges with self-regulating behaviors.

Symptoms can include:

  • Frequent fidgeting or squirming
  • Inability to stay still or seated
  • Persistent restlessness
  • Feeling constantly “on the go”
  • Difficulty engaging in quiet activities
  • Difficulty waiting for a turn
  • Overly talkative
  • Often interrupting

Combined type

Many people with ADHD struggle with paying attention and hyperactive/impulsive symptoms. This is called combined type ADHD, in which symptoms are present for both inattentive and hyperactive/impulsive types.

Learning what type of ADHD you have is important. Understanding exactly how ADHD affects you—and what symptoms show up most in your daily life—empowers you to get the most effective treatment.

ADHD symptoms across age groups

ADHD affects people at all stages of life, but it can pose different challenges depending on age.

ADHD Symptoms in Children

In children and toddlers, ADHD symptoms often surface in environments like home, school, or daycare. Common symptoms can include:

  • Difficulty focusing on activities and becoming easily distracted
  • Short attention span during play or homework
  • Frequent fidgeting, squirming, or trouble sitting still
  • A constant need for movement or frequent running around
  • Engaging in activities loudly or disruptively
  • Excessive talking and interrupting others

ADHD Symptoms in Teenagers

ADHD may evolve as children grow into teenagers. For some, symptoms become less disruptive, but others face new challenges as responsibilities increase. Additional symptoms in teenagers may include:

  • Trouble focusing on or completing schoolwork and other tasks
  • Careless mistakes on schoolwork
  • Frequent mistakes due to inattention
  • Issues with task organization and time management
  • Frequently forgetting or losing personal items
  • Avoiding tasks that require sustained mental effort
  • Increased frustration and emotional sensitivity
  • Difficulties in interpersonal relationships
  • Greater conflict with parents

ADHD Symptoms in Adults

The demands of adulthood can cause another shift in ADHD symptoms. While hyperactivity may decrease with age, struggles with impulsivity, restlessness, and focus often persist. Additional symptoms in adult attention-deficit/hyperactivity disorder may include:

  • Difficulty meeting workplace or academic expectations
  • Low self-esteem and mental health challenges
  • Possible substance use issues
  • Struggles in relationships with partners, family, or coworkers
  • More frequent accidents or injuries

There are effective ADHD treatment options for all ages. Understanding how ADHD symptoms appear differently across age groups can help you better address specific challenges.

Conditions and challenges linked to ADHD

ADHD often occurs with other mental health or behavioral issues. These are some of the most common.

  • Disruptive behavior disorders such as oppositional defiant disorder (ODD) and conduct disorder (CD)
  • Mood disorders like depression and bipolar disorder
  • Anxiety
  • Learning disabilities (or learning disorders) such as dyslexia or issues with speech development
  • Sleep problems
  • Substance use

Difficulties with emotional regulation are also common with ADHD. In addition, living with ADHD can lead to challenges with interpersonal relationships and self-esteem.

Since ADHD often coexists with other challenges, tailored and comprehensive care is essential. A holistic treatment approach addresses ADHD symptoms and related conditions while supporting overall mental and emotional well-being.

What causes ADHD?

The exact causes of ADHD aren’t known, but it likely results from several different factors.

Research indicates that genetics play a significant role in the development of ADHD. Other contributing factors may include differences in brain development, structure, and function, as well as social and family environments.

Possible risk factors for ADHD include: 

  • Having a parent or sibling with ADHD or another mental health condition
  • Exposure to environmental toxins like lead
  • Maternal drug use, alcohol use, or smoking during pregnancy
  • Premature birth

How ADHD symptoms are treated

ADHD symptoms can be managed with effective treatment. The most common treatments involve medication, therapy, or both.

ADHD MEdication

ADHD medications increase the levels of brain chemicals related to attention, motivation, and focus.

Stimulants like Adderall, Ritalin, and Vyvance regulate levels of dopamine and norepinephrine. These medications typically start working quickly and are highly effective for many people with ADHD. However, they are controlled substances and should only be taken as prescribed.

Non-stimulant ADHD medications like Strattera, Guanfacine, and Clonidine primarily increase norepinephrine levels. While they take longer to become effective, they are not controlled substances. Non-stimulants are a good option for those who don’t respond well to stimulants or experience side effects from them, as well as for those who prefer to take other medications.

Therapy

Behavioral therapies, such as cognitive behavioral therapy (CBT), are effective for ADHD. They can help you:

  • Understand and adjust behaviors
  • Improve emotional regulation and executive functioning
  • Build new coping skills

Therapy also gives you the space and support to address challenges related to ADHD, like mood and self-esteem.

What to do if you recognize ADHD symptoms

ADHD diagnoses are complex and require a thorough evaluation by a licensed clinician. This can all be done through online psychiatry. Here’s how it works at Talkiatry.

Screening

You’ll meet with a clinician online to determine whether ADHD could be a factor in daily challenges at work, school, or home. They’ll use standard diagnostic criteria to assess your symptoms.

Evaluation

If the initial screening supports a possible ADHD diagnosis, your clinician will ask additional questions about your health, family history, and daily functioning.

Diagnosis and Treatment

After reviewing this information and ruling out other conditions, your clinician may provide a diagnosis of ADHD. Together, you’ll discuss next steps and possible treatment options, including medication, therapy, and lifestyle changes.

Frequently asked questions

What are the most common symptoms of ADHD in adults and children?

Inattention, which means difficulty paying attention, hyperactivity, and impulsivity are the primary symptoms of ADHD for all age groups. Some people are more affected by certain ADHD symptoms, and the condition is categorized into three main types based on what symptoms are most prominent: inattentive ADHD, hyperactive-impulsive ADHD, and combined ADHD.

Common symptoms of inattentive ADHD include:

  • Trouble paying attention
  • Difficulty completing tasks
  • Easily distracted
  • Daily forgetfulness
  • Disorganization
  • Trouble listening
  • Inability to finish tasks
  • Reluctance to engage in hard tasks

Common symptoms of hyperactive-impulsive ADHD include:

  • Constant fidgeting or squirming
  • Inability to stay still or seated
  • Persistent restlessness
  • Feeling constantly “on the go”
  • Difficulty engaging in quiet activities
  • Difficulty waiting for a turn
  • Overly talkative
  • Often interrupting or blurting out answers

In combined type ADHD, inattentive and hyperactive/impulsive symptoms are both present.

Can ADHD symptoms change over time?

Yes. It’s not uncommon for a person’s experience of ADHD to change over time. Hyperactivity often decreases with age while symptoms of inattention, restlessness, and impulsivity are common symptoms of adult ADHD.

In addition, as responsibilities and expectations increase during adolescence and adulthood, ADHD may present new challenges. Many adolescents and adults with ADHD struggle with time management, organization, and meeting workplace or academic expectations.

How can ADHD symptoms be managed naturally or without medication?

While medication is a common and effective treatment for ADHD, therapy, productivity strategies, and lifestyle changes can also help manage symptoms. A comprehensive care plan from an experienced healthcare provider can support you in finding tools, strategies, and practices that work for you.

Therapy and mindfulness practices:

  • Behavioral therapies, such as cognitive behavioral therapy (CBT), are effective for ADHD. Psychotherapy also gives you the space and support to address challenges related to ADHD, like mood and self-esteem.
  • Mindfulness and meditation practices can also improve attentiveness and focus and reduce stress.

Productivity strategies:

  • Many people with ADHD benefit from breaking down larger projects into smaller tasks. It can be helpful to set deadlines for each of the smaller tasks as well.
  • Try using to-do lists and visual reminders for staying organized and prioritizing school or work assignments.
  • Look for ways to minimize distractions, like creating a clean, clutter-free workspace, using tools that temporarily limit social media access, or wearing noise-cancelling headphones.

Lifestyle changes:

  • Consistent exercise can help with focus and hyperactivity. Since many people with ADHD experience sleep problems, prioritize sleep hygiene and try to maintain a regular sleep schedule.

How do ADHD symptoms differ from normal childhood behavior?

Most children exhibit inattentive, hyperactive, or impulsive behavior at some point. Toddlers and young children have naturally short attention spans and are typically much more energetic than older children and adults. Some children are also naturally more active than others, but these differences aren’t necessarily related to ADHD.

What separates ADHD symptoms from typical childhood inattentiveness or hyperactivity are the intensity, frequency, impact, and persistence of the behaviors. For children with ADHD, inattention, impulsivity, and hyperactivity are often more prominent and frequent, and they can also significantly affect daily functioning. In addition, issues with natural childhood hyperactivity and attention span often resolve on their own without interventions, in contrast to ADHD symptoms, which typically benefit from treatment.
