摘要
Seizures are a common finding in patients with tuberculous meningitis(TBM),and associate with four times increased risk of death and neurological disability,especially in children.It has been reported that brain inflammation,diffuse neuronal injury,and reactive gliosis may all contribute to the pathogenesis of seizures in TBM.Early seizure onset may be associated with meningeal irritation and cerebral oedema;while,the late seizures are usually due to infarction,hydrocephalus,tuberculoma and paradoxical response.Moreover,recurrent uncontrolled seizures can evolve to status epileptics resulting in an increased risk of chronic epilepsy and poor prognosis.Therefore,this review aimed to assess the frequency of seizures in patients with TBM,and discuss the etiologies,mechanisms,and characteristics of seizures in TBM.Besides,we have searched the literature to identify the prognostic factors for chronic epilepsy after TBM.
