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.
The main symptom of a coma is unconsciousness. A patient in a coma will have no conscious response to external stimuli and may appear to be in a deep sleep. The patient in a coma may exhibit spontaneous body movements. Patients may shake or jerk abnormally, and the eyes may move. If the coma is severe, even basic body functions such as breathing may be affected.
