Headache Pain: Stroke Or Something Else?

Experiencing a sharp, sudden headache can be a symptom of a stroke, although it could be caused by something else. Strokes occur when blood flow to the brain is interrupted, and this interruption is what causes the headache. There are two types of strokes: ischemic strokes, which happen when an artery that supplies blood to the brain is blocked, and hemorrhagic strokes, which happen when an artery in the brain bursts. Both types of strokes can cause sudden, severe headaches, and people often describe a stroke-related headache as the worst headache of their life.

A sudden, severe headache is a symptom of a stroke

A stroke is a medical emergency that happens when blood flow to the brain is interrupted. Strokes can cause sudden and intense headaches, and seeking immediate medical attention is crucial. While not all severe headaches indicate a stroke, it is important to be aware of the warning signs and take prompt action.

Strokes are classified into two main types: ischemic stroke and hemorrhagic stroke. An ischemic stroke occurs when an artery supplying blood to the brain becomes blocked, leading to brain cell death. On the other hand, a hemorrhagic stroke happens when an artery in the brain bursts, resulting in bleeding into the brain. Both types of strokes can lead to severe headaches.

During a stroke, the location of the headache pain can vary depending on the site of the stroke. For instance, a blocked carotid artery, the major artery in the neck that supplies blood to the brain, may cause a headache in the forehead. On the other hand, a stroke in the vertebrobasilar system, which supplies blood to the back of the brain, can trigger a headache at the back of the head.

It can be challenging to distinguish a stroke-related headache from a migraine or other types of headaches. However, there are some key differences to note. A stroke-related headache typically comes on suddenly and intensely, with pain that is severe, steady, and fast-hitting. In contrast, a migraine headache often has a gradual onset and is characterised by throbbing pain, along with sensory symptoms like tingling skin or seeing flashes of light.

It is important to remember that a sudden, severe headache can be a symptom of other serious medical conditions as well. Therefore, if you or someone you know experiences a severe headache, especially if accompanied by other stroke symptoms such as weakness, numbness, dizziness, or slurred speech, it is crucial to call emergency services immediately.

Additionally, a "mini stroke" or transient ischemic attack (TIA) can also cause stroke-like symptoms, including severe headaches. While the symptoms of a TIA may subside within a short period, it is still crucial to seek immediate medical attention as it can be a warning sign of an impending full-blown stroke.

Other stroke symptoms include facial drooping, slurred speech, dizziness, and blurred vision

A stroke is a medical emergency that occurs when the blood supply to the brain is interrupted or blocked. This can be due to an artery in the brain bursting or becoming blocked, causing brain cell death. As such, it is important to act fast if you think someone is having a stroke. Knowing the signs and symptoms and acting quickly can improve a person's chances of survival and reduce the level of disability that may result from a stroke.

One of the most common symptoms of a stroke is a sudden and severe headache. This is often accompanied by other classic stroke symptoms, including:

• Facial drooping on one side of the face
• Slurred speech or difficulty speaking
• Dizziness or loss of balance
• Blurred vision or other vision problems

The acronym FAST is often used to help people recognise the signs of a stroke:

• F: Facial drooping
• A: Arm weakness
• S: Speech difficulty
• T: Time to call emergency services

If you or someone you know is experiencing these symptoms, it is important to call emergency services immediately. Do not wait to see if the symptoms go away, as early treatment is vital to improve the chances of survival and reduce potential disabilities.

Ischemic strokes occur when an artery supplying blood to the brain is blocked

A stroke is a medical emergency that happens when blood flow to the brain is interrupted. Ischemic strokes, which account for about 87% of all strokes, occur when an artery supplying blood to the brain is blocked. This blockage causes brain cell death as the brain is deprived of oxygen and nutrients.

Ischemic strokes are primarily caused by atherosclerosis, or fatty deposits (plaques) that line the vessel walls. These fatty deposits can cause two types of obstruction: cerebral thrombosis and cerebral embolism. Cerebral thrombosis occurs when a blood clot, or thrombus, develops at the site of fatty plaque within a blood vessel supplying blood to the brain. On the other hand, cerebral embolism is caused by a blood clot that forms in the heart or large arteries of the upper chest or neck and then travels through the bloodstream to the brain's blood vessels. Atrial fibrillation, an irregular heartbeat, is a significant cause of cerebral embolism.

Ischemic strokes can be further classified into thrombotic strokes and embolic strokes. Thrombotic strokes are caused by blood clots that develop in the blood vessels inside the brain and are commonly seen in older individuals with high cholesterol, atherosclerosis, or diabetes. Embolic strokes, on the other hand, are caused by blood clots or plaque debris that originate elsewhere in the body and travel to the blood vessels in the brain. Heart disease, heart surgery, and atrial fibrillation are often associated with embolic strokes.

The urgent treatment for ischemic stroke is clot removal, which can be achieved through medication and mechanical procedures. Medication with alteplase IV r-tPA, also known as tissue plasminogen activator, can dissolve the clot and improve blood flow to the affected area of the brain. Mechanical thrombectomy involves using a wire-cage device called a stent retriever to remove the clot. This procedure is typically performed within six hours of the onset of acute stroke symptoms but can be extended up to 24 hours if imaging shows undamaged brain tissue.

Hemorrhagic strokes happen when an artery in the brain bursts, causing bleeding

A hemorrhagic stroke is a life-threatening condition that occurs when a weakened blood vessel in the brain ruptures and bleeds into the surrounding brain tissue. This can happen in one of two ways: intracerebral hemorrhage, which is bleeding inside the brain, or subarachnoid hemorrhage, which is bleeding into the subarachnoid space between the brain and its outer covering layer. Hemorrhagic strokes are severe and can deteriorate quickly, so immediate medical attention is crucial to prevent permanent brain damage or death.

The rupture of a blood vessel in the brain can cause a sudden interruption of blood flow to that area, resulting in severe headaches. These "thunderclap" headaches are intense and sudden, like the sound of a thunderclap. They are often described as the worst headache of a person's life and are a key warning sign of a stroke. The location of the headache pain depends on where the stroke is occurring. For example, a blocked carotid artery can cause a headache in the forehead, while a blockage at the back of the brain may result in pain at the back of the head.

In addition to severe headaches, hemorrhagic strokes can present with other classic stroke symptoms, such as facial drooping, slurred speech, and weakness or numbness on one side of the body. It is important to recognize these signs and act quickly by calling emergency services, as the outcome of a hemorrhagic stroke depends on how fast the person receives treatment.

The high mortality rate associated with hemorrhagic strokes is due to the rapid expansion of the hemorrhage, which causes a sudden deterioration of consciousness and neurological dysfunction. The accumulated blood puts pressure on the surrounding brain tissue, damaging or destroying it. This compression can lead to permanent brain damage and even death if not treated promptly.

To diagnose a hemorrhagic stroke, healthcare providers will often use a combination of neurological examinations, diagnostic imaging, and other tests, such as blood tests and electrocardiograms. The most common initial investigation is a computerized tomography (CT) scan, which is considered the "gold standard" for detecting acute hemorrhage.

The treatment of hemorrhagic strokes focuses on reducing bleeding and lowering blood pressure to prevent further damage and promote healing. In some cases, surgery may be necessary to remove accumulated blood and relieve pressure on the brain. Early diagnosis and treatment are crucial for improving outcomes and preventing long-term effects of the condition.

Migraines and stroke-related headaches have overlapping symptoms, but migraines cause sensations like auras and tingling skin

While a sudden, sharp headache can be a symptom of a stroke, it is important to note that migraines and stroke-related headaches share some overlapping symptoms. However, migraines can cause unique sensations like auras, flashing lights, and tingling skin.

A stroke occurs when there is an interruption in blood flow to the brain, and it can be of two types: ischemic stroke and hemorrhagic stroke. Ischemic stroke happens when an artery supplying blood to the brain gets blocked, leading to brain cell death. On the other hand, a hemorrhagic stroke occurs when an artery in the brain bursts, resulting in bleeding into the brain. In both types of strokes, a sudden and intense headache can be one of the symptoms.

Migraines, on the other hand, are severe headaches that can cause throbbing pain, often on just one side of the head. They are often accompanied by nausea, vomiting, and extreme sensitivity to light or sound. One of the distinguishing features of migraines is the presence of auras, which are a set of symptoms that precede the migraine itself. These can include flashing lights, tingling sensations in the face or hands, difficulty concentrating, and extreme sensitivity to light or sound.

While there are some overlapping symptoms between migraines and stroke-related headaches, such as disorientation, a general feeling of being unwell, changes in vision, and vertigo, the key difference lies in the sensations produced. Migraines are more likely to cause sensations like auras and tingling skin, while stroke-related headaches often result in a loss of sensations, such as loss of vision or feeling. Additionally, migraines are typically triggered by recognisable factors, and the pain gradually worsens, whereas strokes can happen randomly and cause sudden, severe pain.

In rare cases, a migrainous stroke can occur, where an ischemic stroke happens alongside a migraine with aura. This accounts for only 0.8% of all strokes and primarily affects women aged 45 and younger.
