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.
Sometimes a coma is induced in patients who are at high risk of brain injury from incidents such as physical trauma, drug overdose or life-threatening seizures. By reducing the activity in the brain and slowing its metabolism, an induced coma can help protect the neural tissue.he conclusions may not extend to cases of comatose patients who have suffered major brain damage, he said. The newly discovered coma state is characterized by electrical waves called Nu-complexes that are unlike other waveforms generated by the brain during known coma states, sleep or wakefulness.
