Role of neuroimaging in management of convulsive epilepsy
Question 6: What is the added advantage of doing neuroimaging in people with convulsive epilepsy in non-specialist settings in low and middle income countries?
- Population: adults or children newly presenting with convulsive seizures
- Interventions: neuroimaging (CT scan or MRI scan)
- Comparison: not applicable
- appropriate diagnosis
- abnormalities detected
- management altered.
Neuroimaging should not be used routinely for the initial diagnosis and starting treatment of epilepsy. It may, however, be used in people with new onset of seizures for the identification of underlying pathologies and to aid in the formulation of syndromic and etiological diagnoses. Neuroimaging should be done in specialized facilities under optimum technical conditions and with adequate expertise for interpretation of the data and results.
Strength of recommendation: STRONG
If both are available, MRI should be preferred over CT scan. It should be considered for people with risk factors for potentially treatable etiologies, including people with partial onset of seizures, intractable or progressive epilepsy and lateralising neurological findings.
Strength of recommendation: STANDARD
