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.
Coma occurs when the brain does not have enough nutrients. For example, if inadequate amounts of oxygen or blood sugar are delivered to it, the brain can turn off. Trauma, bleeding, or swelling of the brain can affect blood delivery, various poisons can also directly injure the brain, and brain inflammation and infection can also alter mental status and lead to coma.
