The patient may become paralyzed on the same side as the lesion causing the pressure, or damage to parts of the brain caused by herniation may cause paralysis on the side opposite the lesion. [11] Damage to the midbrain, which contains the reticular activating network which regulates consciousness, will result in coma. [11]
