Vestibular Circuits in Stroke survivors
Stroke is a common disorder in the elderly and is one of the main causes of permanent disability and mortality. Regardless of the heterogeneity and high inter-subject variability of the effects of stroke, balance and gait problems are one of the most important post-stroke conflicts which, based on evidence, leads to difficulties in motion ability control and locomotor disability. Postural instability is more prominent in patients with right hemisphere damage and probably related to its spatial role. Human spatial orientation uses from purely objects vertical perception for lateralization to gravity and its disorder is related to balance recovery after stroke. The neuroanatomical basis of visual vertical judgment is a vast cortical network, which is organized bilaterally. This cortical network includes several areas of the occipital, parietal, and temporal lobes in addition to the cerebellum and brainstem. These areas play an important role in vertical perception and also play a role in the processing of vestibular information. To date, changes in cortical networks in stroke patients with abnormal vertical perception have not been addressed. In this article, we examined the changes in this network so that by examining the changes, a way can be provided for the better neurorehabilitation of this group of patients.
