If you have dizziness and unstable walking and drifting, the first consideration is cerebrovascular. Insufficient blood supply to the cerebral vessels can also cause dizziness and unstable walking, but in the case of drifting, it is mostly a cerebellar problem. The cerebellum supports the body’s balance, and problems may occur. First, a cranial MRI should be done to check the cerebellum for ischemia, hypoxia or bleeding, which can cause dizziness, unstable walking and drifting. Symptomatic supportive treatment is given for this condition. The neurologist will give you the relevant treatment plan. Generally, after active improvement treatment, you will be able to improve the dizziness and unsteadiness of walking.
