Insights

Children with attention-deficit/hyperactivity disorder (ADHD) show lower brain phosphomonoester (PME) levels in key regions. This suggests a reduced membrane phospholipid mass, potentially impacting neuronal development in ADHD patients.

Area of Science:

  • Neuroimaging
  • Biochemistry
  • Pediatric Neurology

Background:

  • Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder.
  • Altered brain metabolism is implicated in ADHD pathophysiology.
  • Phosphorus magnetic resonance spectroscopy ((31)P MRS) can assess brain metabolites related to cell membrane integrity.

Purpose of the Study:

  • To investigate differences in brain metabolite levels between children with ADHD and healthy controls.
  • To examine specific brain regions including the prefrontal cortex (PFC), basal ganglia (BG), and superior temporal (ST) region.

Main Methods:

  • A multi-voxel (31)P MRS study was conducted.
  • 10 children diagnosed with ADHD and 15 age-matched healthy controls participated.
  • Levels of phosphomonoesters (PME) and other phosphorus metabolites were quantified in the PFC, BG, and ST regions.

Main Results:

  • Children with ADHD exhibited significantly lower PME levels in the PFC and BG compared to healthy controls.
  • No significant differences in PME levels were observed in the ST region.
  • Lower PME levels indicate reduced levels of membrane phospholipid precursors.

Conclusions:

  • The findings suggest a reduced mass of cellular membrane phospholipids in children with ADHD.
  • This deficit in membrane phospholipid precursors may be associated with an underdevelopment of neuronal processes and synapses.
  • These metabolic alterations provide insights into the neurobiological underpinnings of ADHD.

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
Synthesis of Phosphatidylcholine in the ER Membrane01:27

Synthesis of Phosphatidylcholine in the ER Membrane

The ER synthesizes lipids for building cell membranes and performing cellular functions such as energy storage and signaling. The lipid synthesis machinery embedded in the ER membrane primarily collects all reactants from the cytosol. Following synthesis, the secretory pathway and the ER contact sites distribute these lipids to other cellular organelles. Additionally, the energy-rich triacylglycerides are transported from the ER via lipid droplets.

Asymmetric Lipid Bilayer01:35

Asymmetric Lipid Bilayer

Biological membranes show uneven distribution of different types of lipids in the inner and outer layers, resulting in transverse asymmetric membranes. The treatment of the erythrocyte membrane with the enzyme phospholipase confirmed the asymmetric nature of the lipid bilayer. The enzyme hydrolyzes lipids into fatty acids and hydrophilic groups. The phospholipase acts only on the outer layer of the membrane, while the inner layer remains intact. The phospholipase treatment resulted in 80%...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses a challenge in...
