The causes of unsteady walking and poor balance are very diverse and can be considered to be related to Parkinson’s disease, cerebrovascular lesions, vestibular dysfunction and other factors. 1. Parkinson’s disease: it is a common neurodegenerative disease in middle and old age. Postural balance disorders and resting tremor can occur, leading to symptoms such as unsteady walking, abnormal posture and gait, and resting tremor of the upper limbs. 2. Cerebrovascular lesions: for example, cerebellar hemispheric lesions such as cerebellar infarction or cerebellar hemorrhage can cause dizziness, unsteady walking, and tilted walking. 3. Vestibular dysfunction: such as vestibular peripheral vertigo, vestibular neuritis, etc., can lead to vestibular dysfunction, which, in addition to symptoms of vertigo, ear stuffiness, nausea, etc., can also lead to balance disorders and symptoms of unsteady walking. When walking unsteadily with a poor sense of balance, one should be vigilant, and it is recommended to go to the hospital in time to rule out other causes, so as to facilitate the treatment of the cause.
