Summary
Children with epilepsy have higher ADHD risk. This study identified Dlg4 and Vamp2 genes as key molecular factors potentially explaining the comorbidity between epilepsy and attention-deficit hyperactivity disorder (ADHD).
Area of Science:
- Neuroscience
- Genetics
- Molecular Biology
Background:
- Epilepsy in children is frequently comorbid with attention-deficit hyperactivity disorder (ADHD).
- This comorbidity negatively impacts quality of life.
- Understanding shared molecular mechanisms is crucial for effective treatment.
Purpose of the Study:
- To identify molecular mechanisms underlying the comorbidity of epilepsy and ADHD.
- To pinpoint shared genetic factors contributing to both conditions.
Main Methods:
- Utilized gene expression profiles from the Gene Expression Omnibus (GEO) database (GSE12457, GSE47752).
- Screened for differentially expressed genes (DEGs) in epilepsy and ADHD samples compared to controls.
- Applied Weighted Gene Coexpression Network Analysis (WGCNA) to identify relevant gene modules.
- Performed functional annotation and hub gene analysis.
Main Results:
- Identified three key modules associated with both epilepsy and ADHD.
- DEGs within these modules are implicated in synaptic vesicle cycle, neuronal regeneration, and neurotransmission.
- Dlg4 and Vamp2 were identified as common candidate genes in the pathogenesis of both disorders.
Conclusions:
- Dlg4 and Vamp2 may play significant roles in the comorbidity of epilepsy and ADHD.
- Further research into these genes could reveal novel therapeutic targets.

622
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....

01:20Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein
708
Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

01:24Epilepsy and Seizures: Overview
1.0K
Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...
