Main Symptoms of Cerebral Hemorrhage

A cerebral hemorrhage—often called a “bleeding stroke”—happens when a blood vessel in the brain bursts and spills blood into the surrounding tissue. Brain cells are damaged by the pressure of the clot and by the loss of normal blood flow. Symptoms usually start without warning and get worse within minutes to hours. The classic first sign is a sudden, severe headache that most people describe as the worst they have ever felt. Nausea and vomiting often follow. Weakness or numbness on one side of the body is common: the face may droop, the arm may drift downward, or the leg... Learn more

Main Symptoms of Moyamoya Disease

Moyamoya disease is a rare condition in which the large arteries at the base of the brain slowly narrow, forcing tiny backup vessels to develop. These smaller vessels look like a “puff of smoke” on imaging, but they cannot carry enough blood, so the brain is starved of oxygen. Symptoms often start in childhood or early adulthood and can build up gradually or appear suddenly. The earliest warning is usually repeated transient ischemic attacks (TIAs)—brief episodes of weakness, numbness, or trouble speaking that resolve within minutes to hours. Children may complain of a sudden weak arm or leg, slurred speech,... Learn more

Main Symptoms of Brachial Plexus Injury

A brachial plexus injury is damage to the bundle of nerves that travel from the neck into the arm. These nerves control shoulder, elbow, wrist, and hand movement, so even a mild stretch can cause noticeable problems. Symptoms depend on where and how badly the nerves are pulled, torn, or compressed. The most common first sign is sudden weakness or a “dead” feeling in the arm right after an accident—like a car crash, football tackle, or hard fall. The arm may hang limp at the side, and lifting the shoulder or bending the elbow feels impossible. Sharp burning pain often... Learn more

Main Symptoms of Cerebral Infarction

Cerebral infarction is the medical name for what most people call an “ischemic stroke.” It happens when a clot or other blockage shuts off blood flow to part of the brain. The signs can pop up without warning and usually reach their worst within minutes to a few hours. The classic warning is sudden weakness or numbness on one side of the body. One side of the face may droop, the arm may drift downward, or the leg may feel heavy or “dead.” Speech often becomes slurred or garbled; some people can’t find the right words or understand simple sentences....

Main Symptoms of Cerebral Thrombosis

Cerebral thrombosis is a type of stroke that happens when a blood clot blocks an artery in the brain. The signs usually start without warning and get worse over minutes to hours. Knowing what to look for can help you act fast and limit brain damage. The most common first clue is sudden numbness or weakness on one side of the body—face, arm, or leg. Your smile may droop, or you may not be able to lift one hand. Speech can become slurred or jumbled; some people lose the ability to speak at all. Vision may blur or disappear in... Learn more
