A stroke headache location varies but is often sudden, severe, and can be in the back of the head (posterior circulation stroke), forehead/face (carotid artery issues), or generalized, especially with bleeding strokes (hemorrhagic), sometimes described as a "thunderclap" headache affecting the whole head. While common with bleeding strokes, headaches can also signal ischemic strokes, appearing suddenly with other neurological signs like numbness or speech trouble, and always require emergency care.
If in doubt, seek immediate medical attention. Migraine symptoms include a throbbing headache on one side of the head or behind an eye, pain on one side of the body, nausea and vomiting, and sensitivity to light and sound. Stroke symptoms typically include slurred speech, balance issues and a sudden headache.
Standard headaches can cause nausea and neck pain. But a ruptured brain aneurysm can also include symptoms such as loss of consciousness, stroke-like weakness on one side of the face or body, confusion, speech problems or even seizures. Recent bad headaches.
However, there are some other possible symptoms that you should watch out for too: A sudden, severe headache. Sudden dizziness, loss of balance or coordination. Loss of vision or changes to your vision in one or both eyes, which usually happens suddenly.
Check for signs of a stroke
Even without obvious symptoms, silent strokes raise the risk of future strokes and can lead to cognitive decline or vascular dementia. Key warning signs include sudden mood changes, memory issues, balance problems, and cognitive difficulties — but only MRI or CT scans can confirm a silent stroke.
To treat an ischemic stroke, blood flow must quickly be restored to the brain. This may be done with: Emergency IV medicine. An IV medicine that can break up a clot has to be given within 4.5 hours from when symptoms began.
Trouble speaking or understanding. Problems with vision, such as dimness or loss of vision in one or both eyes. Dizziness or problems with balance or coordination. Problems with movement or walking.
“If it ruptures, what it feels like is the worst headache of life, worse than anything you've ever had, like a hammer hitting the back of the head,” says Dr. Patel. Along with a headache, symptoms of a brain aneurysm rupture also include: Confusion or loss of consciousness.
Posterior circulation stroke affects around 20% of all ischemic strokes and can potentially be identified by evaluating or assessing the “Five D's”: Dizziness, drowsiness, dysarthria, diplopia, and dysphagia.
Seek emergency care if:
You experience major side effects to medication, such as severe drowsiness, sedation or nausea and vomiting. The nature, frequency or severity of the headache changes, or the pain feels different from pain associated with previous headaches.
We review the following red flags: (1) systemic symptoms including fever; (2) neoplasm history; (3) neurologic deficit (including decreased consciousness); (4) sudden or abrupt onset; (5) older age (onset after 65 years); (6) pattern change or recent onset of new headache; (7) positional headache; (8) precipitated by ...
If you have a larger aneurysm, you may get symptoms such as: a headache. pain above or around your eye. changes in your vision, such as double vision.
The initial headache duration varied from 1 to 4 days in the 3 studies in which it was reported. Similarly, few studies examined headache persistence during follow-up (on average >3 months) as defined by ICHD-3, with a wide prevalence of persistent headache ranging from 1% to 23%.
A headache becomes serious and requires urgent medical attention if it's sudden and severe (a "thunderclap headache"), the "worst ever," occurs after a head injury, or comes with symptoms like fever, stiff neck, confusion, weakness, numbness, vision changes, seizures, or trouble speaking, as these can signal serious conditions like bleeding, infection, or a tumor. Seek immediate care for new or changing headaches, especially if over 50, accompanied by neurological signs, or preventing normal activities.
The symptoms of hemiplegic migraine – temporary weakness on one side of the body can often be mistaken for a stroke or TIA. Symptoms of migraine with brainstem aura, such as tingling in the hands and feet, dizziness, speech problems and visual disturbances in both eyes can also be mistaken for stroke or TIA.
A pre-stroke headache, often a "thunderclap headache," feels like the sudden, explosive "worst headache of your life," peaking in seconds, potentially with nausea, vomiting, stiff neck, confusion, or vision changes, signaling a medical emergency like a hemorrhagic stroke or TIA (mini-stroke). It's distinct from a gradual migraine, often appearing out of nowhere and accompanied by neurological symptoms like weakness or numbness on one side, difficulty speaking, or balance loss, requiring immediate medical attention (call 911/emergency services).
You may experience warning headaches (called sentinel headaches) from a tiny aneurysm leak days or weeks before a significant rupture.
Can you have a brain bleed and not know it? Yes. It is important to know the subtle signs and symptoms of a small or early brain hemorrhage. Time is your best chance to avoid further neurological damage to the brain.
Look for these signs and symptoms if you think you or someone you know is having a stroke: Sudden trouble speaking and understanding what others are saying. Paralysis or numbness of the face, arm or leg on one side of the body. Problems seeing in one or both eyes, trouble walking, and a loss of balance.
It is estimated that 40-50% of all acute ischemic strokes (AIS) occur in the morning hours.
Not everyone gets a headache before a stroke, but if you have a severe headache, or one that is different from headaches you usually have, it may be a sign of an impending stroke.
Staff in the emergency department will administer acute stroke medications to try to stop a stroke while it is happening. Ischemic stroke, the most common type of stroke, is treated with the 'clot-busting' drug known as tPA.
In the past, the most critical time after a stroke was often referred to as the “stroke window”, “stroke golden hour” or “stroke golden window”. Today, diagnostic imaging tests – which we'll discuss more below – help us determine tissue damage and which treatments may be most effective.
The FAST acronym (Face, Arms, Speech, Time) is a test to quickly identify the three most common signs of stroke.
