In simple words: This is a type of ADHD where the main problem is inattention, making it hard to focus and stay on task.It affects kids more often, making it difficult at school, home, and with friends. It's not that the person doesn't want to pay attention, it is that their brains works in a way that makes it very challenging to do so.While there's no cure, treatments like therapy and medication can help manage symptoms.

This condition, primarily affecting children, involves persistent inattention significantly disrupting home, school, and social life. While hyperactivity-impulsivity may be present, inattention is the predominant symptom cluster.Symptoms include difficulty focusing, sustaining mental effort, organizing tasks, dislike of tasks requiring sustained mental effort, and problems with organization.To a lesser degree, they may be disorganized, talkative, easily distracted, forgetful, impatient when waiting, and fidget in their seats or get up and walk around when they should be seated. They may interrupt others’ conversations and activities and be socially intrusive. Diagnosis is based on medical history, clinical assessment, and interviews with parents, teachers, and others, with nine symptoms required according to the DSM-5.While incurable, treatment aims to improve symptoms through medication (stimulants, non-stimulants for children, antidepressants for adults), behavioral therapy, family/group therapy, skills training, and stress management.

Example 1: A 10-year-old student consistently struggles to follow instructions in class, often losing focus and getting distracted by minor stimuli. They have difficulty completing assignments and exhibit forgetfulness, impacting their academic performance. Despite normal intelligence, their inattention leads to underachievement and frustration., A 35-year-old adult reports chronic difficulty concentrating at work, frequently misplacing items and struggling to meet deadlines. They describe feeling overwhelmed by tasks requiring sustained mental effort and experience challenges with organization and time management, despite a desire to perform well. These symptoms affect their job performance and personal relationships., A 7-year-old child is brought in by their parents due to concerns about their constant fidgeting and difficulty staying seated during mealtimes and quiet activities.While the child does exhibit some hyperactive tendencies, after a thorough evaluation, the primary concern appears to be inattention, manifesting as difficulty focusing on tasks, forgetfulness, and disorganization. A diagnosis of F90.0 is made as inattention predominates the symptom presentation.

Thorough documentation of inattention symptoms, their duration (exceeding six months), and impact on daily functioning (home, school, social).Include observations from parents, teachers, or other relevant individuals. Rule out other conditions like anxiety disorders, mood disorders, and pervasive developmental disorders.Document the diagnostic process, including clinical assessments and interviews conducted.Detailed record of treatment plan, including medication prescribed, therapy modalities, and skills training, is also crucial.

** The subcategory F90-F98 can be used regardless of the patient's age, though these disorders typically onset during childhood or adolescence and may persist throughout life or be diagnosed later in adulthood.Refer to DSM-5 for detailed diagnostic criteria.
