Potential Inflammatory Biomarker in Patients with Attention Deficit Hyperactivity Disorder

Area of Science:

• Neuroscience
• Immunology
• Biochemistry

Background:

• Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder impacting individuals across all life stages.
• The kynurenine pathway (KP), involved in tryptophan metabolism, has been implicated in the risk and development of ADHD.
• Inflammation is increasingly recognized as a potential factor in ADHD pathophysiology.

Purpose of the Study:

• To review the role of the kynurenine pathway (KP) in attention deficit hyperactivity disorder (ADHD).
• To explore the underlying mechanisms of inflammation associated with ADHD.
• To summarize recent findings on inflammatory biomarkers in ADHD.

Main Methods:

• Literature review of recent neurobiological and immunological studies.
• Analysis of research on the kynurenine pathway and tryptophan metabolism in ADHD.
• Synthesis of data on inflammatory biomarkers and their association with ADHD.

Main Results:

• The kynurenine pathway (KP) is significantly associated with ADHD risk.
• Inflammatory processes are implicated in the neurobiological underpinnings of ADHD.
• Recent studies have identified potential inflammatory biomarkers for ADHD.

Conclusions:

• A strong neuroimmunological basis for ADHD is supported by current research.
• The precise pathophysiology of ADHD remains incompletely understood.
• Further investigation into the kynurenine pathway and inflammation is crucial for understanding ADHD.
