Symptoms of brain stroke

What is cerebral venous sinus thrombosis? Cerebral venous sinus thrombosis (CVST) occurs when a blood clot forms in the brain’s venous sinuses. This prevents blood from draining out of the brain. As a result, blood cells may break and leak blood into the brain tissues, forminga hemorrhage. This chain of events is part of a stroke that can occur in adults and children. It can occur even in newborns and babies in the womb. A stroke can damage the brain and central nervous system. A stroke is serious and requires immediate medical attention. This condition may also be called cerebral sinovenous thrombosis. What causes cerebral venous sinus thrombosis? CVST is a rare form of stroke. It affects about 5 people in 1 million each year.The risk for this kind of stroke in newborns is greatest during the firstmonth. Overall, about 3 out of 300,000 children and teens up to age 18 will have a stroke. What are the risk factors for cerebral venous sinus thrombosis? Children and adults have different risk factors for CVST. Risk factors for children and infants include: • Problems with the way their blood forms clots • Sickle cell anemia • Chronic hemolytic anemia • Beta-thalassemia major • Heart disease — either congenital (you're born with it) or acquired (you develop it) • Iron deficiency • Certain infections • Dehydration • Head injury • For newborns, a mother who had certain infections or a history of infertility Risk factors for adults include: • Pregnancy and the first few weeks aft...

The brainstem is the region of the brain that physically and functionally connects higher-level brain activity with the rest of the body. It is also the control center for several life-sustaining functions, such as breathing and heart regulation. The brainstem is located deep in the brain and extends down towards the back of the head, right where the skull and the spine meet. • Weakness or sensory deficits may occur on the side of the body opposite the damaged side of the brainstem. • Double vision can result, because control of eye movements is located in the brainstem. When one eye is not able to move as well as the other normal eye, the lack of symmetric movement produces the perception of two images. Uneven pupils are also associated with brainstem stroke. • • Uneven facial and mouth muscle strength may cause one of the eyelids to droop or one side of the mouth to sag. It can also cause difficulty with swallowing or slurred speech, or may make the tongue point to one side. • Weakness of the shoulders can manifest as an inability to evenly shrug the shoulders. • • Webers syndrome: Webers syndrome is a midbrain stroke that causes weakness of the opposite side of the body combined with eyelid weakness and weakness of eye movements on the same side. • Locked-in syndrome: Locked in syndrome is a stroke that affects the • Wallenberg syndrome: Also called lateral medullary syndrome, Wallenberg syndrome characteristically causes sensory deficit of the face on the same side as ...

A stroke occurs when blood flow to the brain is limited, causing damage to brain cells. There are warning signs that indicate a person is experiencing a stroke, but these occur suddenly. When the brain does not get blood, the brain A person should call 911 immediately if someone they are with experiences any symptoms of stroke — especially if they occur suddenly.

However, some people may experience a Unlike a stroke, a TIA People who have already experienced a stroke also have a Therefore, while stroke symptoms occur suddenly, a person may consider a TIA or previous stroke as early warning signs of future stroke. Many organizations, such as the • Face drooping: One side of a person’s face may droop, and if someone asks them to smile, they may not be able to. • Arm weakness: A person may not be able to raise both arms — one of their arms may drift downward when they try. • Speech difficulty: A person’s speech may become slurred or unusual. • Time to call 911: Someone should call 911 immediately if they notice any of the symptoms above in themselves or others. Signs of a stroke can • numbness or weakness in the face, leg, or arm on one side • an unusually severe • slurred speech • • difficulty seeing or • l...
