Medical researchers from the University of New South Wales (UNSW) and the Black Dog Institute have carried out the largest and most definitive study of tDCS and found up to half of depressed participants experienced substantial improvements after receiving the treatment,according to Sciencedaily
Transcranial direct current stimulation (tDCS) involves applying weak electrical currents to the head, to generate an electromagnetic field which modulates the activity of brain neurons. tDCS is known to selectively modulate neuronal excitability and can be used in conjunction with fMRI, transcranial magnetic stimulation (TMS) or centrally acting drugs. It is being investigated as a treatment for a variety of conditions such as stroke recovery, depression and migraine.
Electroacupuncture application increased or decreased the brain function- as assessed by changes to the blind spot-depending on the treatment side: Contralateral-side treatment has a better effect than ipsilateral-side treatment on brain function.
Chinese researcher found that Acupuncture can significantly increase blood flow and oxygen saturation in brain cortex, and the effect with combined therapy of scalp and body acupuncture is superior to that with body acupuncture.
Any idea about this research?
Another research:BOOSTING the effect of acupuncture needles with small electric currents may be effective in treating depression, a study in Hong Kong has found. Led by Zhang Zhang-jin at the School of Chinese Medicine, University of Hong Kong, the researchers used electroacupuncture to stimulate seven spots on the heads of 73 participants, who had suffered several bouts of depression in the last 7 years.
