The following reasons are common for walking to the right: First, cervical spondylosis: such as vertebral artery cervical spondylosis, or mixed cervical spondylosis, can cause cerebral blood supply deficiency and vertebral artery stenosis in the middle segment, and the patient will have cerebellar blood supply insufficiency, thus manifesting as unstable walking and easy skewing to the right. The extent of the lesion can be found through vascular ultrasound examination and vascular MRI examination. Second, brain disease: patients suffering from cerebral hemorrhage, cerebral thrombosis, resulting in serious dysfunction of the central nervous system, will also appear walking to the right side of the skew, affecting normal walking, while patients will have clinical symptoms such as numbness of the affected limb, muscle atrophy will also be obvious, even the corners of the mouth will have saliva outflow, bilateral frontal lines asymmetry, through CT, MRI examination can be found intracranial lesions. Therefore, timely consultation, diagnosis and treatment are necessary for walking to the right.
