In a hemispheric stroke, facial weakness is ipsilateral to the motor weakness due to the organization of the brain's motor pathways. The facial muscles are primarily controlled by the facial nerve (cranial nerve VII), which receives input from both hemispheres of the brain. However, the upper part of the face (forehead) is bilaterally innervated, while the lower part of the face is primarily controlled by the contralateral hemisphere. Thus, when there is a stroke affecting one hemisphere, the lower facial muscles on the same side are weakened, resulting in ipsilateral facial weakness alongside contralateral limb weakness.
What else can I help you with?
Signs and symptoms of a stroke can include?
facial drooping, slurred speech, and unilateral muscle weakness.
Is the pupillary light reflex contralateral or ipsilateral?
The patellar reflex is ipsilateral. If the stimulus is applied to left knee cap, the left knee responds. On the other hand, if the right knee were to respond to a left knee stimulus, the response would be considered contralateral.
Why is there muscle weakness after a stroke?
When there is apparent muscular weakness after a diagnosed stroke, the problem typically is not with the muscle, but with interruption of the neural pathways that access the muscle in question. As the stroke has killed off some of the neural connections to that muscle or muscles, weakness will appear until (and if) a sort of "re-routing" occurs and neural pathways are established once more.
What is an acute stroke?
An acute stroke is a sudden onset of impaired blood flow to the brain, leading to brain cell damage. It requires immediate medical attention to minimize brain injury and potential long-term disability. Symptoms can include facial drooping, arm weakness, and speech difficulty.
A patient has had a stroke and has a right-sided weakness which side should you assist from?
Behind them
What does the acronym FAST stand for to know if you are having a stroke?
F is facial weakness. Ask the casualty to smile, both sides should move together. A is arm weakness. Ask the casualty to raise both arms, if one or both are not moveable seek medical aid S is speech. Is the casualty able to make coherent speech. T is time. If one or more of these symptoms are present the casualty must get medical aid within 2 hours and the effects of the stroke may be reversible.
Is it possible to identify possible stroke symptoms in conjunction with a person's lifestyle?
While lifestyle factors can contribute to an increased risk of stroke, the symptoms of a stroke are primarily related to sudden changes in neurological function, such as facial drooping, arm weakness, and speech difficulties. Identifying these symptoms promptly is crucial for timely medical intervention and better outcomes in stroke management.
What are heat stroke symptoms?
The main symptoms of heat stroke are nausea, vomiting, dizziness, weakness, fatigue and headaches. If you suspect heat stroke, you should cool and hydrate the victim and seek medical attention.

What are some of the early warnings of a stroke?
Many people do not know the signs of an oncoming stroke. They can be sudden weakness, trouble speaking, and loss of vision. If you think you are having a stroke seek medical help immediately.
What does FAST stand for?
Act fast. Also; Face - check the facial expression is normal as sometimes a stroke victim may loose control of facial muscles. Arms- ask the person to see if they can hold out their arms, check for weakness Speech - see if they can say a simple sentence Time- if any of the above is not normal, time to call 999. The quicker, the better. With more time lost, you will loose more of that person.
