N/A Chronic renal diseases. Intervention 1: In main intervention, Subject of two "anxiety and depression" and "sleep disorders" groups were under tDCS.F3-Fp2 protocol was used in main intervention group according to 10-20 system of regions of the brain, the area (F3) Dorsolateral Prefrontal Cortex (DLPFC) was stimulated with anode and contralateral supraorbital (Fp2) under cathodic inhibition. The stimulation started in ascending mode up to 2 mA, and with the enhanced of 2 mA continues for 20 minutes and then, the device automatically shuts down. Intervention 2: in placebo group, Subject of two "anxiety and depression" and "sleep disorders" groups were under tDCS.F3-Fp2 protocol was used in main intervention group according to 10-20 system of regions of the brain, the area (F3) Dorsolateral Prefrontal Cortex (DLPFC) was stimulated with anode and contralateral supraorbital (Fp2) under cathodic inhibition. The stimulation started in ascending mode up to 2 mA, and with the enhanced of 2 mA continues for 30 seconds and then, the device automatically shuts down.
