Attention Deficit Hyperactivity Disorder (ADHD)
Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that affects millions of children and adults worldwide. It influences attention, impulse control, and activity levels, making everyday tasks more challenging. While ADHD often begins during childhood, many individuals continue to experience symptoms into adulthood — sometimes without proper diagnosis.
Early identification and proper management help improve academic performance, work success, relationships, and emotional well-being.
What is ADHD?
ADHD (Attention Deficit Hyperactivity Disorder) is a chronic condition where the brain has difficulty regulating attention, behavior, and impulses due to differences in brain structure, connectivity, and neurotransmitter activity.
It mainly affects:
• Cognitive processes (attention, organization, planning)
• Behavioral control (hyperactivity, impulsivity)
• Emotional regulation (frustration, mood changes)
ADHD is recognized by major medical authorities including WHO and APA.
Types of ADHD
According to the DSM-5 classification, ADHD is categorized into three types:
ADHD Type Key Characteristics
Predominantly Inattentive Difficulty focusing, disorganized, forgetful
Predominantly Hyperactive-Impulsive Fidgeting, excessive talking, impulsive actions
Combined Type (Most common) Both attention and hyperactivity symptoms present
Causes and Risk Factors of ADHD
There is no single cause. ADHD is believed to result from a combination of factors:
1 Genetics
• ADHD tends to run in families
• About 70–80% of cases have a genetic link
2. Brain Structure and Function
People with ADHD may show:
• Lower dopamine & norepinephrine levels
• Differences in frontal lobe development
• Altered neural connectivity
3. Prenatal and Perinatal Factors
• Maternal smoking, alcohol, or drug exposure
• Premature birth
• Low birth weight
• Pregnancy complications
4. Environmental Factors
• Exposure to lead or toxic substances
• Severe childhood stress or trauma
5. Diet and Lifestyle
While not direct causes, food additives, artificial colors, and high sugar intake may worsen symptoms in some individuals.
Signs and Symptoms of ADHD
Symptoms must be persistent and age-inappropriate to be diagnosed as ADHD.

Feature Children Adults
Hyperactivity More visible May appear internal (restlessness)
School/Work Impact Poor grades, disciplinary issues Reduced productivity & job stress
Social Skills Impulsive interaction Strained relationships
Self-awareness Often lacking Better awareness but frustration
Diagnosis of ADHD
ADHD has no single laboratory test. Diagnosis requires comprehensive evaluation by:
• Psychiatrists
• Pediatric neurologists
• Clinical psychologists
Diagnostic Criteria:
• Symptoms present for ≥ 6 months
• Onset before age 12
• Symptoms affecting school/work/home/social life
• Rules out other disorders (e.g., anxiety, autism)
• Assessment Tools Include:
• Behavior rating scales (e.g., Conners, Vanderbilt)
• Interviews with parents/teachers
• School performance history
• Cognitive and psychological testing
Can ADHD Be Prevented?
While ADHD cannot always be prevented because of its genetic base, risk and severity can be reduced by:
• Healthy pregnancy care: avoiding alcohol, tobacco, drugs
• Preventing exposure to environmental toxins
• Early childhood care with proper nutrition
• Managing screen time and promoting outdoor play
• Positive parenting and structured routines
• Early identification of developmental delays
Healthy environments reduce symptom severity and improve functioning.
Treatment and Management of ADHD
ADHD treatment combines medications, therapy, education, and lifestyle modification.
1. Medication Treatment
Stimulant medications (first-line treatment):
• Methylphenidate (Ritalin, Concerta)
• Amphetamines (Adderall)
Non-stimulant medications:
• Atomoxetine
• Guanfacine
• Bupropion (sometimes used for adults)
Benefits:
• Improves focus, attention, and behavior
• Effective in 70–80% of cases
Possible side effects:
• Sleep difficulties
• Decreased appetite
• Headaches
• Mood changes
Regular healthcare monitoring is essential.
2. Behavioral and Psychological Therapies
• Cognitive Behavioral Therapy (CBT)
• Social skills training
• Parent-child interaction therapy
• Classroom behavior interventions
Helps improve emotional regulation and decision-making.
3. Educational Support
• Individualized Education Program (IEP)
• Special educational accommodations
• Flexible learning strategies
Examples of classroom modifications:
• Seat child at front
• Break large tasks into smaller chunks
• Use visual aids and positive reinforcement
4. Lifestyle and Home Strategies
For Children
• Daily structured routine
• Limited screen usage (≤ 1–2 hours/day)
• Healthy sleep (8–10 hours)
• Sports, yoga, and outdoor play
For Adults
• Calendar & task-management apps
• Breaking tasks into smaller steps
• Stress-management practices
5. Diet and Nutrition
• High-protein foods (egg, fish, nuts)
• Omega-3 fatty acids (salmon, flaxseed)
• Fresh fruits and vegetables
• Reduce refined sugar, artificial colors, and preservatives
Some individuals benefit from:
• Iron, zinc, and magnesium supplementation (if deficient)
Holistic & Emerging Treatments
• Neurofeedback therapy
• Mindfulness meditation
• Music and art therapy

FAQs About ADHD
Is ADHD a mental illness?
ADHD is a neurodevelopmental disorder, not a psychiatric illness like depression. However, it can occur with mental health conditions.
Can a child outgrow ADHD?

Does too much screen time cause ADHD?
Not directly, but excessive screen exposure can worsen symptoms.
Are ADHD medications addictive?
When prescribed and monitored, they are safe and not addictive.
Can girls have ADHD?
Yes — though girls often show more inattentive symptoms and may be underdiagnosed.
Conclusion
ADHD is a lifelong yet manageable condition. With early diagnosis, proper treatment, and supportive care, children and adults can lead productive and fulfilling lives. Stigma should never prevent diagnosis — awareness leads to empowerment.
