How Are Brain Contusions Different from Brain Concussions? Head trauma can damage brain tissue in more than one way. Two types of brain injury are contusion and concussion, but--contrary to popular belief--one is not just a worse version of the other.Keywords:

Surgical and non-surgical treatments of proven effectiveness are available for this pinched-nerve condition.Keywords:

Instead, physicians use a sequential process heavily influenced by an understanding of probability.Keywords:

However, rigorous evidence of their benefit is scant.Keywords:

Strokes that involve bleeding within the brain are more likely to disable and kill their victims, and are less treatable, than those that involve blocked blood vessels.Keywords:

They must be identified and removed in order to minimize brain damage.Keywords:

Humpty could easily have been referring to words used by patients to describe their symptoms.Keywords:

It can be confused with other conditions. Symptom-relieving, but not curative, treatment is available.Keywords:

However, used unwisely, they can cause more harm than good.Keywords:
