Inattentive ADHD is a presentation of attention deficit hyperactivity disorder (ADHD). People with this form often struggle to focus, stay organized, and keep their attention on tasks. They may also have trouble controlling impulses and sitting still.

In our work at AuDHD Psychiatry where we assess and support individuals and families with ADHD, we often see how inattentive ADHD can go unnoticed for years because its signs are less outwardly disruptive. As such, diagnosis involves looking at patterns of attention, behaviour, and day-to-day functioning over time using established clinical frameworks. Understanding inattentive ADHD can help people recognise the signs earlier and explore the kinds of support that make everyday life more manageable.

Key Takeaways

• Inattentive ADHD is a type of ADHD that presents less noticeable symptoms, such as daydreaming, losing items and missing details.
• Inattentive ADHD in women has a tendency to go unnoticed because some overcompensate at home and at work, masking symptoms that can be mistaken for other conditions like mood disorders and anxiety.
• Inattentive ADHD is diagnosed through a carefully structured, evidence-based approach so that clinicians get the full picture of an individual’s experiences across all settings.
• The treatment for predominantly inattentive ADHD is a combination of medication, therapeutic interventions and lifestyle strategies.

What Is Inattentive ADHD?

ADHD presents in three different ways: 

• Predominantly inattentive – People with this type of ADHD tend to experience poor concentration and more problems with organisational skills.
• Predominantly hyperactive-impulsive – People with this type of ADHD often fidget and talk excessively, not seeming to slow down.
• Combination – People with this type of ADHD experience symptoms from both inattentive and hyperactive-impulsive types.

Inattentive ADHD used to be called attention deficit disorder (ADD), up until 1987, when ‘hyperactivity’ was added to the term.

Predominance of inattention does not mean a person with ADHD will not have hyperactive-impulsive symptoms. It only means that they experience more inattention symptoms and fewer hyperactive-impulsive symptoms.

Here are some of the key differences between the ADHD types:

ADHD Inattentive Type	ADHD Hyperactive/Combined Type
Less noticeable	More visible
Main challenges are focus, organisation and memory	Main challenges are impulse control and activity level
Common issues involve missing details, daydreaming and losing items	Common issues are fidgeting, interrupting and overtalking

What Are Inattentive ADHD Symptoms?

ADHD people who are predominantly inattentive will have problems paying attention. They are easily distracted, so they have a tendency not to complete tasks. They will also likely forget routine obligations, such as paying bills on time or returning phone calls. They’ll have trouble managing their time and finishing homework (for kids) or meeting their deadlines (for adults).

Inattentive ADHD may present differently in children and adults.

Here are inattentive ADHD symptoms according to age groups.

Adults

• Get bored quickly
• Process information slowly
• Easily distracted
• Miss details, becoming less accurate at work
• Have a problem organising thoughts and learning new information
• Have difficulty staying focused on tasks like reading or listening in meetings
• Have a tendency to misplace or lose items

Children

• Appear not to listen when someone is speaking to them, or daydreaming
• Have trouble focusing on a task or when playing
• Struggle with following instructions
• Easily distracted
• Have a tendency to lose things
• Have a problem finishing tasks or chores
• Avoid activities that require focused mental effort

Most symptoms of ADHD in adults are hidden, especially in women. Inattentive ADHD in women sometimes goes unnoticed because some mask symptoms by overcompensating. They might over-prepare for presentations or meetings or work later than most, resulting in chronic exhaustion or self-criticism. 

Some women diagnosed with ADHD inattentive type may also struggle with maintaining long-term relationships, become highly sensitive to rejection or deal with ‘internal hypersensitivity’.

Because some of the experiences resemble other conditions like anxiety or mood disorders, inattentive ADHD in female patients tends to be missed or underdiagnosed.

How Inattentive ADHD Is Diagnosed

An accurate diagnosis is essential to get the right treatment. With most inattentive ADHD symptoms typically subtle, a careful, structured and thorough ADHD assessment is necessary. An assessment like this involves behavioural observations across different settings, such as school, work and home. An evidence-based approach also involves in-depth interviews and detailed background information to create a complete picture for clinicians.

Some people may start with an online screening for ADHD to gain further insight into their experiences. An online screening is quick and simple, and results are sent instantly. The results can be used to guide an initial consultation with a GP, who will then provide a referral for an ADHD specialist to do a diagnostic assessment. The assessment may include an inattentive ADHD test to confirm the symptoms.

The ADHD specialist will also conduct medical or psychological tests to rule out or confirm other conditions. Once a complete assessment results in an ADHD diagnosis, the specialist comes up with treatment options.

Treatment Options for ADHD Inattentive Type

Inattentive ADHD is manageable. Depending on the outcome of a diagnosis, the ADHD specialist may prescribe one or two (or all) of the following treatments:

• Therapy
• Medication
• Lifestyle strategies

Medication is generally the first line of defense to help manage inattentive ADHD symptoms. Some medications can include:

• Psychostimulants (e.g., methylphenidate like Concerta or Ritalin),
• Nonstimulants (e.g., atomoxetine and guanfacine)
• Antidepressants (e.g., bupropion and venlafaxine)

As with any neurodevelopmental condition, medication is never sufficient. ADHD medication must be supported by therapeutic intervention, such as cognitive behavioural therapy or coaching for inattentive ADHD. Therapy can develop self-regulation and emotional resilience. A support group or group therapy may also be helpful because it builds a connection with people who share similar experiences.

Lifestyle strategies can support the work being done through therapy and medication. These lifestyle strategies can include:

• Following a routine at school or work
• Using visual planners to encourage organisation and time management
• Exercising to improve focus and concentration

The Causes of Inattentive ADHD

The exact causes of inattentive ADHD are still undetermined as scientists continue to study it. Some factors may contribute to its development. These include:

• Early childhood stress may intensify or make symptoms more noticeable, although it is not considered a direct cause of ADHD.
• Differences in brain chemistry particularly involving neurotransmitters such as dopamine and norepinephrine can also affect how the brain manages attention, motivation, and impulse regulation.
• Low birth weight and being born prematurely have both been linked to a higher likelihood of developing attention-related difficulties later in life.

The bottom line is ADHD, inattentive or hyperactive-impulsive types, is not about poor parenting, laziness or lack of discipline. It is about brain development affecting executive functions and creating everyday challenges for children and adults.

Frequently Asked Questions on Predominantly Inattentive ADHD

Understanding ADHD – Predominantly Inattentive Type

In England, currently an estimated 2.4 million people have the neurodevelopmental condition, including those without a diagnosis. Although it is a lifelong condition, ADHD can be managed. The first step is to recognise the symptoms and determine whether it might be ADHD inattentive type.

If you or a loved one has been struggling with predominantly inattentive ADHD, take the first step to getting clarity. A clinician-led ADHD assessment can help you understand what is happening and what kinds of support may help.
