ABSTRACT

The human brain shows a remarkable degree of recovery of its functions following postnatal damage. Recovery can be spontaneous and therapy guided. Early spontaneous recovery following stroke is mostly due to the resolution of diaschisis, a sudden loss of function in regions adjacent or connected to, but at a distance from, the damaged area. Crossed cerebellar diaschisis (CCD) describes a pattern of hypo-metabolism in a cerebellar hemisphere secondary to a lesion in the contralateral cerebral hemisphere and present in 50 percentage of the cases. There are three basic forms of NIBS methods. The first two are repetitive transcranial magnetic stimulation (rTMS) and paired associative stimulation (PAS). The third non-invasive brain stimulation (NIBS) technique is that of transcranial direct current stimulation (tDCS). Results of the application of non-invasive brain stimulation techniques in treating motor and language disorders following stroke are, at present, promising, but no definite conclusions can be drawn.
