Summary
This study found that pseudoseizures are more common in women and those with prior psychiatric issues. Many patients with pseudoseizures achieved seizure freedom, but a higher percentage relied on disability pensions.
Area of Science:
- Neurology
- Psychiatry
Background:
- Pseudoseizures (psychogenic non-epileptic seizures) are often misdiagnosed as epilepsy.
- Understanding risk factors and prognosis is crucial for effective patient management.
Purpose of the Study:
- To investigate risk factors associated with pseudoseizures.
- To evaluate the long-term prognosis of patients diagnosed with pseudoseizures.
Main Methods:
- A matched pairs case-control study was conducted with out-patients from an Epilepsy Clinic.
- The study included 28 patients with pseudoseizures and 28 age- and sex-matched epileptic patients.
Main Results:
- A significant female preponderance (86%) was observed in the pseudoseizure group.
- Previous psychiatric problems were more frequent in pseudoseizure patients, while major cerebral damage and idiopathic generalized epilepsy were less prevalent.
- At a median 5.8-year follow-up, 45% of pseudoseizure patients were seizure-free.
- A higher proportion of pseudoseizure patients (55%) received public disablement pensions compared to controls (23%).
Conclusions:
- Pseudoseizures are associated with a history of psychiatric issues and a female demographic.
- While many patients can achieve seizure remission, long-term outcomes may include significant disability and reliance on social support.
