Primary objective: Beneficial effects of transcutaneous electrical nerve stimulation (TENS) on cognition and behaviour were observed in a child with probable Herpes Simplex Encephalitis. Based on these positive findings, it was examined in the present case study whether a child who had been diagnosed to suffer from tuberculous meningitis would benefit from TENS. Furthermore, as aggression and overactive behaviour were also prominent clinical symptoms, the effects of methylphenidate were investigated. Methods and Procedures: Neuropsychological tests were used to assess attention/concentration and visuospatial and visuoconstructive memory. Behaviour, including the level of activity during 24 hours, was assessed by one observation scale and actigraphy. Experimental interventions: TENS and methylphenidate. Main outcomes and results: TENS particularly improved overall affective behaviour. Methylphenidate appeared to have the opposite effect on cognition and hardly any effect on patient's behaviour. Conclusions: TENS might improve the patient's behavioural functioning. Pros and cons for treatment effects are discussed.
