Microcurrent is a low intensity current at the same voltage found in your body. When it is applied to the brain specifically, it is known as CES, or Cranial Electrotherapy Stimulation. You hardly feel it when it is applied. CES uses Alternating (or ‘biphasic’) Current, and not Direct Current. It means that the two electrodes being used continually switch polarity between positive and negative, so no need to remember which electrode is positive or negative. This effectively reduces the risk of tissue damage, as local tissues don’t become polarized.
It is used to improve the symptoms of:
- Depressed mood, loss or grief,
- Anger or irritability,
- Insomnia, and nightmares,
- Lack of concentration / shortened attention span,
- Memory deficits,
- After a stroke or spinal cord injury,
- Lack of drive and motivation and
CES is most commonly applied through the earlobes, although one can also stick pre-gelled electrodes behind the ears or on the shoulders.
