Application of transcranial direct current stimulation in refractory seizures in tuberculous meningitis: a case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Tuberculous meningitis (TBM) is a devastating form of tuberculosis with high mortality and long-term neurological sequelae. Seizures, including refractory status epilepticus, are common complications and portend a poor prognosis. While neuromodulation techniques such as vagus nerve and deep brain stimulation have been used in refractory epilepsy, there are no prior reports of transcranial direct current stimulation (tDCS) in refractory seizures related to TBM. We report a 19-year-old woman with pulmonary tuberculosis who developed TBM with multiple central nervous system tuberculomas and refractory status epilepticus unresponsive to multiple antiseizure medications, intravenous anesthetics, and steroids. A structured course of cathodal tDCS was initiated (10 sessions, once daily for 10 days, 2 mA amplitude, 20 minutes per session, ramp-up 10 seconds, impedance 4 kΩ; cathode over electroencephalogram-localized epileptic focus, anode over contralateral supraorbital region). Following the intervention, sedation was successfully tapered, and the patient was discharged seizure-free on oral therapy. At the 1-month follow-up, she remained seizure-free and demonstrated clinical improvement, with no new neurological deficits. This case demonstrates the feasibility and potential benefit of tDCS as an adjunctive therapy for refractory seizures in TBM. While causality could not be established, this is the first report of tDCS application in TBM-related seizures. Controlled studies with objective neurophysiological endpoints are warranted.
