Posted October 13, 2025 Updated October 13, 2025 Author: Avery Lombardi, MSc Reviewed by: Dr. Rebecca Fernandez, MBBS

Inattentive-type ADHD is a subtype of ADHD that is primarily characterised by attention difficulties rather than hyperactivity or impulsivity. Often referred to as ADD (Attention Deficit Disorder), this type of ADHD is commonly underdiagnosed, especially in children and adults who may not exhibit the hyperactive traits typically associated with ADHD.

Individuals with inattentive-type ADHD struggle with sustaining focus on tasks, staying organised, and following through on instructions. These difficulties can lead to challenges at school, work, and in daily life. Unlike other subtypes of ADHD, people with the inattentive type often appear quiet or daydreamy, making it easier for their struggles to go unnoticed or misinterpreted as laziness or lack of motivation.

Key Symptoms of Inattentive-Type ADHD

Here are key symptoms of inattentive-type ADHD:

Frequent Distractions

People with inattentive ADHD find it hard to stay focused on tasks, especially long or boring ones. They might easily become distracted by external stimuli or their own thoughts, which can lead to incomplete work or forgotten tasks.

Forgetfulness

Memory issues, such as forgetting appointments, losing personal items, or missing deadlines, are common in individuals with this type of ADHD.

Difficulty Following Instructions

Attention difficulties make it hard to follow multi-step directions or organise tasks, often resulting in unfinished projects or errors.

Disorganisation

Adults and children with inattentive-type ADHD may struggle to keep their workspaces or schedules organised, leading to confusion or missed opportunities.

In conclusion, while inattentive type of ADHD can still significantly impact an individual’s academic, personal, and professional life. Early diagnosis and appropriate strategies, such as therapy or medication, can help manage these symptoms effectively.
