Attention Deficit Hyperactivity Disorder (ADHD) is a complex neurodevelopmental disorder, with symptoms that vary depending on age, gender, and individual characteristics. The condition is broadly categorized into three main symptom groups. Let’s explore these symptoms in detail.

1. Symptoms of Inattention

Inattention is one of the hallmark features of ADHD and can significantly impact daily life:

  • Difficulty Paying Attention to Details: Individuals with ADHD tend to overlook details, making careless mistakes in schoolwork, job tasks, or other activities. For instance, they may solve all the steps of a math problem correctly but make a simple mistake in the final step, leading to an incorrect answer.

  • Problems Sustaining Attention: Even in enjoyable activities such as playing games, they struggle to stay focused for extended periods. While reading a book, they may realize after a few pages that their mind has wandered elsewhere.

  • Appearing Not to Listen: Even when directly spoken to, they may seem as though they are not listening. They may act as if they did not hear what was said or struggle to recall information shortly after hearing it.

  • Difficulty Following Instructions: They often struggle to follow directions and complete assignments or tasks. Remembering and executing multi-step instructions can be particularly challenging.

  • Organizational Difficulties: Individuals with ADHD often struggle to organize tasks and activities. They may have difficulty managing time effectively, meeting deadlines, and keeping their workspace tidy. They frequently misplace belongings.

  • Avoidance of Mentally Demanding Tasks: They may show reluctance or actively avoid tasks that require sustained mental effort, such as completing homework, filling out forms, or writing long reports.

  • Frequent Misplacement of Items: They often lose everyday items such as pens, books, phones, and keys or forget where they placed them.

  • Easily Distracted: External stimuli, such as background noises or unrelated thoughts, can easily divert their attention.

  • Forgetfulness in Daily Activities: They frequently forget appointments, assignments, or daily routines.

2. Symptoms of Hyperactivity

Hyperactivity is characterized by excessive and inappropriate physical movement:

  • Restlessness: They may frequently move their hands or feet, fidget in their seats, or twist in their chairs. Sitting still can feel unbearable for them.

  • Inability to Stay Seated: In situations where sitting is expected (e.g., classrooms, office meetings), they may feel compelled to get up and move around.

  • Excessive Running or Climbing: Children with ADHD may run or climb in inappropriate situations, whereas adults may experience an internal sense of restlessness.

  • Difficulty Engaging in Quiet Activities: They struggle to participate in quiet activities, always seeming to be in motion or acting as if they have a motor inside them.

  • Excessive Talking: They may talk continuously and at a fast pace, often in a disorganized manner.

  • Constant Need for Activity: They feel the need to always be engaged in something and find it difficult to remain idle.

3. Symptoms of Impulsivity

Impulsivity refers to acting without considering the consequences:

  • Answering Questions Before They Are Fully Asked: They may interrupt and answer before a question has been completely spoken, often trying to predict what will be asked.

  • Difficulty Waiting Their Turn: They struggle to wait their turn in games or group activities, showing impatience and frequently interrupting.

  • Interrupting Others: They often disrupt conversations or activities, change the subject mid-conversation, or finish other people’s sentences.

  • Acting Without Considering Consequences: They may engage in risky behaviors without thinking about the potential consequences, leading to financial problems, accidents, or social conflicts.
