Hematoma is blood: Concussion refers to the constellation of symptoms after a head injury. This can include amnesia, headache, memory problems, blurred or double vision. Hematoma refers to structural damage that can be visualized by cat scan in the brain. A subdural hematoma is a specific blood clot that is between the lining(dura) of the brain and the brain. It is best detected by ct scan of the head.

Definitions: Concussion: "head injury resulting in loss of consciousness, loss or memory, or combination of both." hematoma: a localized area of bleeding within the brain, and can be above the outer covering, an "epidural hematoma", or below the dura, a "subdural hematoma". Hematoma can occur in absence of concussion. Mri films invariably reveal presence of such bleeding.

CT should be adequate and appropriate. MRI usually not necessary.

Bleeding vs.concussi: A hematoma represents a collection of blood. It may be in the brain, or outside the brain between the membranes covering the brain or outside the brain between the brain and the skull. A concussion reprents a change in mental status, and represents mt least a mild brain injury. Most recover fully from a single concussion, but some can be quite serious.

Absolutely: Especially in older patients, many subdural hematomas show little to no symptoms depending on size of the hematoma, location, and how old it is.
