is bleeding between the inside of the skull and the outer covering of the brain (called the dura).
Often caused by a skull fracture during adolescence or childhood.
This can also happen because of a rupture of a blood vessel or artery.
Rapid bleeding causes a collection of blood (hematoma) that presses on the brain.
The pressure inside the head (intracranial pressure, ICP) increases quickly.
This pressure may result in more brain injury

Collection of blood on the outside of brain.
Usually caused by severe head injuries.
The bleeding and pressure on the brain can be life threatening.
Some subdural Hematomas resolve themselves, others require surgery to drain.

A weakness in a blood vessel in the brain that balloons and fills with blood.
Area of a blood vessel gets worn out from constant flow of blood and buldges.
Sometimes you won't even notice that there's an aneurysm as they can resolve on their own.
A ruptured brain aneurysm can be life-threatening
in rare cases, aneurysms can grow big, leak, or explode.
Brain Hemorrhage

Type of stroke caused by an artery bursting. This causes localized bleeding in surrounding tissues. This kills Brain cells.
hemorrhages are also called cerebral hemorrhages, intracranial hemorrhages, or intracerebral hemorrhages. They account for about 13% of strokes.
When blood from trauma irritates brain tissues, it causes swelling. This is known as cerebral edema. The pooled blood collects into a mass called a hematoma.
These conditions increase pressure on nearby brain tissue, and that reduces vital blood flow and kills brain cells.
slowly expanding with blood.
Rapidly expanding with blood.
Brain Trauma Definition
An object that penetrates brain tissue, such as a bullet or shattered piece of skull, also can cause traumatic brain injury. Mild traumatic brain injury may affect your brain cells temporarily. More-serious traumatic brain injury can result in bruising, torn tissues, bleeding and other physical damage to the brain.
The bleeding in a subdural hematoma is under the skull and outside the brain
Brain injuries are very serious and while some of these things may resolve on their own, it is important to see a doctor if you think something is wrong inside your brain. Screening can save lives.
You cannot tell if you have a brain aneurysm until it ruptures.
Signs an aneurysm has ruptured are...
.
-Sudden very severe headache
-Nausea and vomiting
-stiff neck
-blurred and or double vision
-sensitivity to light
-seizure
-drooping eyelids
-loss of consciousness
-Confusion

In head injuries with sudden, severe bleeding causing a subdural hematoma, a person may lose consciousness and become comatose immediately.
A person may appear normal for days after a head injury, but slowly become confused and then unconscious several days later.
This results from a slower rate of bleeding, causing a slowly enlarging subdural hematoma.
In very slow-growing subdural hematomas, there may be no noticeable symptoms for more than two weeks after the bleeding starts.
