From the Research
The risk of absence seizures in the offspring of affected parents is significantly increased, with a higher risk associated with mothers who have epilepsy, as evidenced by a 1.45-fold higher risk compared to having an affected father 1.
Key Points to Consider
- The inheritance pattern of absence epilepsy is complex and multifactorial, involving multiple genes that affect brain excitability and neuronal synchronization.
- Environmental factors may interact with genetic predisposition to influence seizure development.
- Children with a parent who has absence seizures have a higher chance of developing absence seizures themselves, although the exact percentage is not specified in the most recent and highest quality study.
- If a child does develop absence seizures, treatment typically involves anti-seizure medications, and parents should consider genetic counseling before family planning and monitor their children for warning signs.
- A study from 2021 found that having an affected mother was associated with a higher risk of epilepsy in the offspring, compared to having an affected father, which may be relevant to absence seizures as well 1.
Treatment and Management
- Anti-seizure medications such as ethosuximide, valproic acid, or lamotrigine may be used to treat absence seizures.
- The quality of the family environment can have varied effects on intellectual development, and children with prenatal risks may be more vulnerable to environmental disadvantage 2.
- Parents with absence seizures should be aware of the potential risks and take steps to monitor their children's development and adjust their environment to support their children's needs.
Relevant Studies
- A 2021 study found a clear maternal effect on offspring risk of epilepsy, with a 1.45-fold higher risk associated with having an affected mother compared to an affected father 1.
- A 2020 study provided insight into the pathophysiology, comorbidity, and therapy of absence seizures, highlighting the importance of careful choice of initial monotherapy and continuous neuropsychiatric evaluation of affected children 3.
- A 2017 study reviewed the main syndromic presentation of absence seizures and its outcome regarding treatment and prognosis, noting that absence seizures can occur at all ages and clinical presentation varies widely 4.
