Social activist and writer Mahasweta Devi continues to be in a critical condition, a doctor said, stressing the nonagenarian litterateur is responding to treatment.

"Neurologically she is doing better but she still requires dialysis," a doctor told the media.

The 90-year-old Ramon Magsaysay awardee suffers from various ailments and was put on non-invasive ventilation earlier in July after her condition worsened.

The writer, who was honoured with the Jnanpith Award in 1996, has been undergoing treatment at a hospital here for about two months now.
