Summary
Attention deficit hyperactivity disorder (ADHD) frequently co-occurs with childhood epilepsy, impacting quality of life. Early ADHD identification and management in children with epilepsy are crucial for better outcomes.
Area of Science:
- Neurology
- Child Psychiatry
- Genetics
Background:
- Comorbidities are prevalent in pediatric epilepsy, affecting nearly half of patients.
- Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by hyperactivity and inattention.
- The co-occurrence of ADHD in children with epilepsy significantly impacts clinical outcomes, psychosocial well-being, and quality of life.
Purpose of the Study:
- To review the high burden of ADHD in children with epilepsy.
- To discuss the bidirectional relationship and shared factors between epilepsy and ADHD.
- To highlight the importance of early identification and management of comorbid ADHD.
Main Methods:
- Literature review of existing studies on epilepsy and ADHD comorbidity.
- Analysis of proposed hypotheses for the association between epilepsy and ADHD.
- Evaluation of current treatment strategies and safety data for stimulants in comorbid ADHD.
Main Results:
- A strong bidirectional connection and shared genetic/non-genetic factors exist between epilepsy and ADHD.
- Stimulant medications are effective and generally safe for treating ADHD in children with epilepsy at approved doses.
- Comorbid ADHD remains under-recognized in clinical practice, necessitating improved diagnostic approaches.
Conclusions:
- Early recognition and management of ADHD in children with epilepsy are vital for optimizing prognosis and preventing adverse neurodevelopmental outcomes.
- Further research, including randomized controlled trials, is needed to solidify safety data for stimulant use.
- Identifying shared genetic underpinnings may pave the way for precision medicine approaches in treating comorbid epilepsy and ADHD.

135
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.

01:24Epilepsy and Seizures: Overview
234
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...

01:24CNS Stimulants: Cocaine, Amphetamines and Cannabinoids
299
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...

01:30Electroconvulsive Therapy
96
Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...

01:13Seizures: Classification
486
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

01:19Autism Spectrum Disorder
177
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
