Kasper and colleagues investigated the efficacy of lavender oil (WSÂ® 1265) for AD NOS in comparison to placebo in a primary care setting.62 This study was the first double-blind, randomized, placebo-controlled trial to document the anxiolytic efficacy of orally administered lavender essential oil for anxiety disorder.
Some examples are: 1  Traumatic brain injuries. Traumatic brain injuries, often caused by traffic collisions or acts of violence, are common causes of comas. 2  Stroke. Reduced or interrupted blood supply to the brain (stroke), which may be caused by blocked arteries or a burst blood vessel, can result in a coma. 3  Tumors.
Problems that can lead to coma include: 1  Trauma: Head injuries can cause the brain to swell and/or bleed. 2  Swelling: Swelling of brain tissue can occur even without distress. 3  Bleeding: Bleeding in the layers of the brain may cause coma due to swelling and compression on the injured side of the brain. This compression causes the brain to shift, causing damage to the brainstem and the RAS (mentioned above).
