Hemorrhagic strokes are particularly dangerous, as they may go undetected. For example, someone who forcefully hits his head may simply ice his wound and not seek medical treatment, unaware that blood is leaking into his brain from a ruptured vessel. When blood leaks into the brain, the blood gathers and begins to compress the brain tissue. At the same time, the damaged vessel does not deliver blood as it normally does. Since the brain cannot function without a steady supply of blood oxygen and nutrients, the brain begins to die and may cease functioning. Hemorrhagic strokes can result in impaired movement, speech, cognitive ability, and physical functioning and may even cause death.

Certain risk factors may increase one's likelihood for developing a hemorrhagic stroke:

• High blood pressure
• Bleeding disorders (such as hemophilia)
• Blood vessel abnormalities
• Brain tumor
• Liver disease
• Drug abuse

There are two types of hemorrhagic stroke: intracranial hemorrhage stroke and subarachnoid hemorrhage stroke. Intracranial hemorrhages cause bleeding inside of the brain, while subarachnoid hemorrhages happen when bleeding occurs in the region between the brain membrane and the brain. Both types of hemorrhagic strokes require immediate medical treatment, which can prevent severe and life-threatening brain damage. Signs of hemorrhagic stroke include:

• Fever
• Disorientation or confusion
• Difficulty speaking
• Difficulty walking
• Impaired vision
• Weakness in the face, legs, or arms
• Severe headaches

When someone suspected of having a stroke reaches the hospital, the patient will usually receive a CT or other scan that provides an image of the brain. The scan results can reveal clotted or leaking blood in the brain. Physical exams, neurological exams, and blood tests may also be used to check for blood clotting and sugar. Treatment generally begins immediately if a stroke is detected.

Hemorrhagic strokes are treated with blood-saving medication and surgery. For a hemorrhagic stroke caused by an aneurysm (blood vessel bulges) rupture, surgery might be performed to stem the bleeding. Another treatment is endovascular coiling, where a catheter (thin, hollow needle) is used to place a platinum wire coil at the spot of the aneurysm. The coil blocks bleeding and prevents the aneurysm from continuing to leak blood. A similar technique is stent-assisted coiling, which adds a stent (small wire-meshed tube) into the blood vessel to block the leaking opening of the aneurysm. These procedures are usually combined with blood-thickening medications. Blood transfusions may be administered if substantial blood loss has occurred.

Hemorrhagic stroke patients who may have lost some essential functions while the blood flow to their brains was obstructed may receive post-stroke rehabilitation to rebuild their physical and mental abilities. Some restorative treatments include occupational, physical, and speech therapy. Patients may also receive care from a neurologist, who can develop individual treatment plans, and rehabilitation psychologists who may help patients with their emotional, behavioral, and cognitive recovery. Some stroke patients require lengthy rehabilitation and may never fully regain function, while others may recover more quickly. While the fastest recovery improvements are usually seen in the first three or four months, rehabilitation from hemorrhagic stroke can last for years.

If someone begins to show signs of hemorrhagic stroke, contact emergency services and call 9-1-1 immediately, since blood flow must be restored as soon as possible to avoid significant brain damage. If an ambulance takes the person to the hospital, paramedics can initiate hemorrhagic stroke treatment as soon as the patient enters the ambulance, allowing for more prompt medical intervention and care.

There are two main types of stroke: ischemic stroke and hemorrhagic stroke. Ischemic stroke occurs more commonly and is when a blood vessel in the brain becomes blocked. Blockages are caused by blood clots and built-up plaque (deposits of fat and cholesterol), which leads to atherosclerosis, a condition where the blood vessels narrow and harden. The resultant restricted blood flow may lead to an ischemic stroke by blocking essential oxygen to the brain, causing the heart to exert more effort to pump blood.

Hemorrhagic stroke occurs when a blood vessel in or around the brain ruptures. The burst vessel leaks blood into surrounding brain tissue, causing irreparable brain damage.

Hemorrhagic strokes are less common and may occur from head injuries, brain aneurysms, brain tumors, and bleeding disorders, amongst other conditions.

Both ischemic and hemorrhagic strokes require immediate medical treatment. Medical intervention can prevent severe and life-threatening brain damage. Signs of stroke include:

-Disorientation or confusion

-Difficulty speaking

-Difficulty walking

-Impaired vision

-Weakness in the face, legs, or arms

-Severe headaches

The scan results can reveal clotted or leaking blood in the brain. Physical exams, neurological exams, and blood tests may also be used to check for blood clotting and sugar. Treatment begins generally immediately if a stroke is detected.

Medical treatment for ischemic strokes includes a thrombolytic medicine which breaks up and disperses blood clots. This medicine can greatly improve stroke recovery and long-term health. However, the thrombolytic medicine must be administered as soon as possible to achieve these results. Other treatments for ischemic strokes are blood thinners and thrombectomy, a surgical procedure to remove a blood clot in the brain. Thrombectomy is performed by inserting a catheter (thin needle) into the artery to reach the blood clot and mechanically remove it. With the clot removed, normal blood flow to the brain resumes. Thrombectomy is typically performed at most six hours after a patient shows signs of a stroke.

Hemorrhagic strokes are treated with blood-saving medication and surgery. For a hemorrhagic stroke caused by the rupture of an aneurysm (blood vessel bulges), surgery to stem the bleeding aneurysm and vessel may be used. One surgical technique is stent-assisted coiling, which adds a stent (small wire-meshed tube) into the blood vessel to block the leaking opening of the aneurysm. A non-surgical procedure is endovascular coiling, where a catheter (thin, hollow needle) places a platinum wire coil at the spot of the aneurysm. The coil blocks bleeding and prevents the aneurysm from continuing to leak blood. These procedures are usually combined with blood-thickening medications. Blood transfusions may be administered if substantial blood loss has occurred.
