Severe injuries can also cause lasting effects that vary — including memory loss, paralysis, seizures, and lasting behavioral or cognitive changes — depending on the areas of the brain affected. But in those cases, unconsciousness is a symptom of the injury, not a cause of long term deficits.

The length of medically induced coma varies depending on the situation and how long it takes to achieve the desired outcome. It may be only 12 hours, or it can last for several weeks; in one case, the patient was kept in a coma for 6 months.

Radiation to the brain can also have side effects that show up later – usually from 6 months to many years after treatment ends. These delayed effects can include serious problems such as memory loss, stroke-like symptoms, and poor brain function.

Some people experience a mild headache following an injection into the muscles in the forehead. It can last a few hours to a few days. According to a 2001 study, about 1 percent of patients may experience severe headaches that can last for two weeks to one month before slowly disappearing.

In coma, which typically is present for the first one to two weeks after brain injury, patients are not awake or aware, meaning that they do not open their eyes, have only reflex responses and are unaware of those around them. If a coma lasts more than two or three weeks, it evolves into the vegetative state.
