Differential Diagnosis for 5 Symptoms of Inattention and/or Hyperactivity/Impulsivity

Single Most Likely Diagnosis

  • Attention Deficit Hyperactivity Disorder (ADHD): This is the most likely diagnosis given the symptoms of inattention and/or hyperactivity/impulsivity that have persisted for at least 6 months, which aligns with the diagnostic criteria for ADHD.

Other Likely Diagnoses

  • Anxiety Disorders: Anxiety can manifest with symptoms of inattention and restlessness, which may mimic ADHD. A comprehensive evaluation is necessary to differentiate between the two.
  • Mood Disorders: Certain mood disorders, such as bipolar disorder, can present with symptoms of hyperactivity and impulsivity, making them a consideration in the differential diagnosis.
  • Sleep Disorders: Sleep disturbances, like sleep apnea or insomnia, can lead to symptoms of inattention and hyperactivity, making them an important differential diagnosis.
  • Substance Use Disorders: The use of certain substances can lead to symptoms that resemble ADHD, such as increased activity and difficulty sustaining attention.

Do Not Miss Diagnoses

  • Hypothyroidism: Although less common, hypothyroidism can cause symptoms of inattention and fatigue, which could be mistaken for ADHD. Missing this diagnosis could lead to untreated hypothyroidism, resulting in significant morbidity.
  • Pheochromocytoma: This rare tumor can cause episodic symptoms of hyperactivity, impulsivity, and inattention due to excess catecholamine release. Missing this diagnosis could be life-threatening.
  • Traumatic Brain Injury: Certain types of traumatic brain injuries can result in symptoms of inattention, hyperactivity, and impulsivity. Failing to diagnose and treat the underlying condition could lead to worsening symptoms and decreased quality of life.

Rare Diagnoses

  • Neurodegenerative Disorders: Rare neurodegenerative disorders, such as frontotemporal dementia, can present with symptoms of inattention, hyperactivity, and impulsivity. While uncommon, considering these diagnoses is crucial for providing appropriate care.
  • Genetic Disorders: Certain genetic disorders, such as fragile X syndrome, can manifest with symptoms similar to ADHD. Identifying these conditions is important for genetic counseling and targeted interventions.
