Symptoms of chronic subdural hematomas are usually delayed more than three weeks after injury. [1] If the bleeds are large enough to put pressure on the brain, signs of increased intracranial pressure or brain damage will be present. [3] Other symptoms of subdural hematoma can include any combination of the following: [7]
A subdural hygroma (SDG) is a collection of cerebrospinal fluid (CSF), without blood, located under the dural membrane of the brain. Most subdural hygromas are believed to be derived from chronic subdural hematomas. They are commonly seen in elderly people after minor trauma but can also be seen in children following infection or trauma.
Subdural hemorrhage (SDH) results from tearing of the bridging veins in the subdural space between the dura and arachnoid mater. It can cross the suture lines, but not across dural reflections such as falx cerebri or tentorium cerebelli. [4] Therefore, subdural hematoma always limited to one side of the brain. [3]
Intracerebral hemorrhages is a severe condition requiring prompt medical attention. Treatment goals include lifesaving interventions, supportive measures, and control of symptoms. Treatment depends on the location, extent, and cause of the bleeding. Often, treatment can reverse the damage that has been done.
Since the skull does not decrease in size with the brain, there is significant space between the two when this occurs which puts the elderly at a higher risk of a subdural hematoma after sustaining a closed head injury. [9] The reduction of brain size can lead to issues with eyesight, cognition and hearing. [11]

Symptoms of IVH are similar to other intracerebral hemorrhages and include sudden onset of headache, nausea and vomiting, together with an alteration of the mental state and/or level of consciousness. [6] Focal neurological signs are either minimal or absent, but focal and/or generalized seizures may occur. [6]
Epidural hematomas may occur in combination with subdural hematomas, or either may occur alone. [10] CT scans reveal subdural or epidural hematomas in 20% of unconscious people. [ 15 ] In the hallmark of epidural hematoma, people may regain consciousness and appear completely normal during what is called a lucid interval , only to descend ...
