Posterior dizziness can be caused by a slowing of blood flow in the vessels of the posterior circulation, such as the bicuspid or basilar arteries, and the patient may experience posterior dizziness, dizziness, and, in severe cases, mild nausea. For examination, the patient can be given an intracranial segmental vascular ultrasound, which can reveal a significant slowing of blood flow in both vertebral or basilar arteries. Some patients, especially younger ones, present with posterior coma due to vasospasm of the posterior circulation. Due to persistent vasoconstriction, which also affects the blood supply to the posterior circulation, the patient may experience posterior coma. In addition, drowsiness of the back of the head can be seen clinically in some patients with cervical spondylosis, due to the patient’s prolonged ambulatory work, resulting in continuous contraction of the muscles and fascia of the back of the occipital region, which can also be manifested as drowsiness of the back of the head, which can be accompanied by pain in the back of the occipital region in severe cases, and the treatment is mainly based on massage, traction and physiotherapy.
