If the cause of the coma can be successfully treated, the person may eventually awaken with no permanent damage.They are likely to be confused at first, but then they usually remember what happened before the coma, and be able to continue their life. Typically, some rehabilitation therapy is necessary.If brain damage has occurred, long-term impairment may result. If the person awakens, they may need to relearn basic skills, and they may not remember what happened.However, with support, such as physical and occupational therapy, many people can enjoy a good quality of life.

In some cases, the person will not wake up.


In 2015, neurologists published findings showing that there may be a way to predict when patients will awaken from a coma. During a coma, specific patterns of neuronal communication appear to be disrupted.Using functional MRI (fMRI) tests, the scientists noticed that patients who retained a particular strength of neuronal communication were more likely to recoverTrusted Source from a coma.This could mean that fMRI might be able to predict a person’s likelihood of recovery. Another study carried out in 2015 found evidenceTrusted Source that voices of family members and loved ones could help improve responsiveness in people during a coma. After 15 patients who underwent either familiar auditory sensory training (FAST) or placebo silence, fMRI scans show improvements in the brains of those who experienced FAST.
