Attention Deficit Hyperactivity Disorder

Attention Deficit Hyperactivity Disorder (ADHD) is a chronic neurodevelopmental condition characterized by persistent patterns of inattention, hyperactivity, and impulsivity that interfere with daily functioning or development. It typically manifests in childhood and often persists into adulthood, impacting executive function, academic performance, and social interactions.

ADHD is multifactorial. Genetics play a primary role, with heritability estimated at 70–80%. Environmental factors include low birth weight, prenatal exposure to alcohol, tobacco, or lead, and early childhood traumatic brain injury.

ADHD involves dysregulation of catecholamine neurotransmission—specifically dopamine and norepinephrine—within the frontostriatal circuits of the brain. Structural imaging reveals potential volume reductions in the prefrontal cortex, basal ganglia, and cerebellum, leading to deficits in inhibitory control and working memory.

Global prevalence is approximately 5–7% in children and 2.5–3% in adults. It is diagnosed more frequently in males (3:1 ratio), though females are often under-diagnosed due to predominantly inattentive presentations.

Genetic predisposition, premature birth, low birth weight, maternal substance use during pregnancy, and neurodevelopmental stressors.

A. Early Symptoms
Difficulty focusing on tasks, excessive movement, frequent fidgeting, impulsive vocalizations. B. Common Symptoms
Poor organization, forgetfulness, difficulty sustaining attention, interrupting others, inability to sit still, reckless behavior. C. Advanced Symptoms
Chronic occupational underachievement, relationship instability, risky driving, substance misuse. D. Emergency Symptoms
Suicidal ideation or extreme self-destructive behavior (often comorbid with depression or conduct disorder).

Physical exams are generally normal; however, clinicians may observe motor restlessness, difficulty maintaining eye contact, or excessive talking during the interview.

A. Clinical Assessment: DSM-5 criteria; parent/teacher rating scales (Conners, Vanderbilt).
B. Laboratory Testing: None diagnostic; used to rule out mimics.
C. Imaging Studies: Not used for routine diagnosis.
D. Functional Tests: Neuropsychological testing for executive function.
E. Biopsy Findings: N/A.
F. Genetic Testing: Not indicated.
G. Differential Diagnosis: Anxiety, Bipolar disorder, Learning disabilities, Sleep disorders.

Complete Blood Count
Type: Blood Test
Purpose: Rule out anemia or infections causing fatigue/inattention.
Expected Findings: Normal range.
Interpretation: Normal findings exclude physiological systemic illness.

MRI Brain: Not routine; used only if focal neurological deficits are present to rule out structural lesions or tumors.

Anxiety (worry-induced distraction), Bipolar Disorder (episodic hyperactivity), Learning Disabilities (frustration-based inattention), and Sleep Apnea (fatigue-related inattention).

Academic failure, social isolation, substance use disorders, mood disorders, and high-risk health behaviors.

A. Lifestyle Modifications: Structured routines, sleep hygiene, physical exercise.
B. Preventive Measures: Early intervention and consistent educational support.
C. Medical Treatment: - Stimulants: Methylphenidate, Amphetamines (increase dopamine/norepinephrine).

• Non-stimulants: Atomoxetine (SNRI), Guanfacine (Alpha-2 agonist).

With early diagnosis and multimodal treatment, many individuals reach age-appropriate milestones, though 50-60% experience persistent symptoms into adulthood.

No primary prevention exists; secondary prevention involves early screening in primary care settings.
