Symptoms of Stroke

Stroke is caused by an interrupted blood supply to a portion of the brain and can cause a variety of symptoms and signs. The most common ones are hard to miss, but many people discount the symptoms without realizing how serious they are.

Strokes are treatable, so it is important to be able to recognize a stroke, so that you can get the right emergency treatment. If you see or experience any of the following symptoms and signs of a stroke, it's important to get immediate medical help, as a stroke is an emergency.

Frequent Symptoms

Recognizing the symptoms of a stroke can save a life. The symptoms of a stroke can be remembered by the acronym FAST:

  • Facial drooping
  • Arm weakness
  • Speech difficulties
  • Time to call emergency services

Face Weakness

Weakness in face muscles as a symptom of stroke manifests as drooping of one eyelid or sagging of one side of the face. Sometimes one side of the face appears to be flat and the mouth may curve down. The tongue may also be affected, with the inability to move the tongue to one side of the mouth.

Arm or Leg Weakness

A weakness of the arm, the leg, or both is a common stroke symptom. When a stroke causes physical weakness of the extremities, it typically affects only one side of the body.

You may notice partial weakness, which means that you do not have full strength, or complete weakness where you cannot move the limb all. Arm weakness may cause you to drop items or may make you unable to reach for objects. Sometimes mild leg weakness can cause you to lean toward one side, while severe leg weakness can make you fall down.

Slurred Speech

Slurred speech may be more noticeable to others than to the person who is having a stroke. Frequently, slurred speech is associated with drooling and is often related to facial weakness.

Falling

Leg weakness can result in falling—a startling event that may cause injury. Therefore, if you notice someone fall down and there is any chance that he or she can't get up without assistance, or suffered a head bump, it is really important to call for help.

Loss of Vision

Visual loss from a stroke can manifest in a number of different ways that cut off vision in only half of one eye or in one-half of both eyes, often referred to as hemianopsia.

If you suddenly experience vision loss, you need to get help even if you can see a little bit or if you can see out of the sides of your eyes. Hemianopsia is painless, but it is disturbing and may cause you to blink your eyes as you try to figure out what is going on with your vision.

Language Problems

Sudden language problems are among the hallmark symptoms of stroke. Aphasia, a deficit in language, may manifest as trouble producing fluent or coherent words and phrases, trouble understanding written or spoken language, or a combination of any of these problems.

Severe Headache

A stroke does not always cause a headache, but a severe headache can signal a stroke, particularly a hemorrhagic stroke. A sudden, severe headache that is different than your usual headaches may be a symptom of a stroke, particularly if there are other associated symptoms such as visual changes or weakness. These tips can help you sort out when you need to worry about headaches.

Confusion

A stroke can cause confusion due to the effect it has on the brain. Sudden confusion, disorientation, or forgetfulness may be a symptom of stroke or another medical emergency.

Dizziness

Dizziness, a sense of instability, or wobbliness are all possible symptoms of stroke. If you experience a sense that you cannot hold yourself up or that you or your surroundings are spinning, it is important to get medical attention.

Rare Symptoms

Less common symptoms of a stroke include:

Incontinence

Bladder and bowel control requires a sophisticated interaction between several regions of the brain. Sudden incontinence is not typically the first symptom of a stroke, but it may be the first noticeable indication of a stroke in some instances.

Numbness, Tingling or Sensory Loss

Sensory problems such as tingling or numbness, or the inability to feel your face, arm, or leg may be the first symptom of a stroke. Typically, a stroke causes more prominent concerns, but sudden sensory problems, while less common, can be the first symptoms that appear.

Strange Sensations

Unusual sensations may be the first symptoms of stroke. Overall, skin burning or crawling sensations are typically signs of neuropathy, not a stroke. However, neuropathy develops slowly over time. Sudden disturbing sensations are concerning and may signal a stroke.

Change in Vision

Most of the time, visual changes signifying a stroke fall into the category of visual field cuts. However, there are some other visual change patterns as well, including loss of vision in only one eye and loss of color vision.

Hiccups

One of the less common and intriguing symptoms of stroke, persistent hiccups, can be the most noticeable and bothersome symptom of a small stroke in the brainstem. The other symptoms of this type of brainstem stroke, called Wallenberg syndrome, include face and limb weakness, and sensory deficits.

Coordination Problems

A stroke does not usually target coordination. However, an uncommon stroke called a cerebellar stroke may produce coordination problems that are more prominent than weakness or other symptoms.

Cognitive Deficits

A stroke can interfere with concentration, memory, and learning. A deficit in thinking skills and dementia-like symptoms are usually more long-term effects of a stroke, rather than symptoms of a new one.

However, a new stroke can cause sudden cognitive problems, particularly if silent strokes have already had a quiet impact on brain reserve.

Complications

Stroke is treatable in the first few hours after stroke symptoms begin. Emergency stroke treatment requires a trained medical team that can act quickly to administer powerful medications that can reduce or reverse the obstruction of blood flow before it causes permanent brain damage.

Long-term effects of stroke can include:

  • Weakness of one side of the body
  • Weakness of one side of the face; a droopy eyelid
  • Vision loss or partial vision loss
  • Double vision or blurred vision
  • Slurred speech
  • Trouble understanding words or trouble with language
  • Balance and coordination problems
  • Loss of sensation of one side of the body or face
  • Lack of awareness of your surroundings or of your own body
  • Difficulty with problem-solving
  • Dizziness, headaches, and pain
  • Urinary incontinence

Recovery after a stroke can take time for the brain to heal before assessing any permanent damage that has occurred. Many stroke patients undergo physical or occupational therapy to regain skills they may have lost as a result of the stroke.

When To Go To The Hospital

If you experience or witness someone with any of the symptoms of a stroke, call emergency services and get to a hospital.

Stroke is treatable in the first few hours after stroke symptoms begin.

Emergency stroke treatment requires a trained medical team that can act quickly to administer powerful medications that can reduce or reverse the obstruction of blood flow and prevent permanent brain damage.

After a stroke, symptoms typically stabilize and often improve. However, new symptoms such as seizures, spasticity, muscle atrophy, depression, and swallowing problems may develop.

A Word From Verywell

It's important to know the signs and symptoms and signs of a stroke in the event you may experience one or witness someone who is having one. If you suspect that you may be having a stroke, get medical help right away. The sooner care is received, the better the outcome typically is.
