🧠 Chapter A1 – Module 3: ADHD

 


ADHD (Attention-Deficit/Hyperactivity Disorder) is a neurodevelopmental condition that affects attention, activity levels, and impulse control. It usually begins in childhood but often continues into adulthood.

It affects how the brain manages:

  • Focus and attention
  • Movement and energy levels
  • Impulse control and decision-making

🧬 What ADHD Is

ADHD is characterised by persistent patterns of:

  • Inattention
  • Hyperactivity
  • Impulsivity

These patterns can interfere with:

  • School or work performance
  • Social relationships
  • Daily organisation and routines

It is not caused by laziness or lack of discipline.


🧠 Types of ADHD

ADHD is grouped into three main types:

🎯 Combined Type

  • Most common type
  • Includes both inattention and hyperactivity/impulsivity

🧩 Inattentive Type

Focus-related difficulties:

  • Easily distracted
  • Forgetfulness
  • Poor organisation
  • Difficulty sustaining attention

⚡ Hyperactive/Impulsive Type

Movement and impulse-related traits:

  • Fidgeting or restlessness
  • Excessive talking
  • Interrupting others
  • Difficulty sitting still

⚠️ Symptoms of ADHD

🧠 Inattention Symptoms:

  • Difficulty focusing on tasks
  • Losing items frequently
  • Poor time management
  • Forgetting instructions
  • Making careless mistakes

⚡ Hyperactivity & Impulsivity:

  • Constant movement or fidgeting
  • Talking excessively
  • Interrupting conversations
  • Acting without thinking

🧬 Causes and Risk Factors

ADHD does not have one single cause. It is linked to brain development and genetics.

Key factors include:

🧬 Genetics

  • ADHD often runs in families

🧠 Brain Differences

  • Changes in brain areas linked to attention and control
  • Differences in dopamine activity (a brain chemical linked to reward and focus)

🌍 Environmental influences

  • Early life stress
  • Pregnancy or early developmental factors may play a role

🧠 How ADHD Affects the Brain

Research shows differences in:

  • Attention regulation systems
  • Movement control areas
  • Decision-making pathways

This affects:

  • Focus consistency
  • Emotional regulation
  • Impulse control

🏥 Diagnosis and Prevalence

  • Usually diagnosed in childhood
  • Can continue into adulthood

📊 Estimates:

  • Around 1 in 10 children (US estimates)
  • Around 5% of adults worldwide show symptoms

💊 Treatment and Management

There is no cure, but ADHD can be managed effectively.

🧠 Behavioural Therapy

  • Helps build coping strategies
  • Improves organisation and emotional regulation

💊 Medication

  • Stimulant medications (commonly used)
  • Non-stimulant options available

🧩 Lifestyle Support

  • Structured routines
  • Regular exercise
  • Good sleep habits
  • Balanced nutrition

🧩 Key Strengths (Important Perspective)

People with ADHD may also show:

  • Creativity and problem-solving skills
  • High energy and enthusiasm
  • Strong interest-based focus (hyperfocus)
  • Out-of-the-box thinking

⚠️ Everyday Challenges

ADHD can affect:

  • School performance
  • Work organisation
  • Time management
  • Relationships
  • Emotional regulation

🧠 Important Understanding

  • ADHD is a neurological condition, not a behavioural choice
  • It affects brain function and regulation systems
  • Support and strategies can significantly improve outcomes
  • Early understanding helps reduce stigma
