What areas of the brain are affected in a stroke?

Here are the major areas of the brain that can be affected by stroke:

• Frontal Lobe Stroke. Almost one third of the cerebrum is comprised of the frontal lobe.
• Parietal Lobe Stroke.
• Temporal Lobe Stroke.
• Occipital Lobe Stroke.
• Brain Stem Stroke.
• Cerebellar Stroke.
• Thalamic Stroke.
• Basal Ganglia Stroke.

What part of the brain is most affected by stroke?

A stroke can affect any part of the brain. When one of the main arteries that provides blood to the brain becomes blocked, an ischemic stroke can result, which means that the impaired region of the brain no longer functions as it should. The largest region of the brain is called the cerebral cortex.

What is the most common stroke location?

Middle Cerebral Artery (MCA) Infarction The middle cerebral artery (MCA) is the most common artery involved in stroke. It supplies a large area of the lateral surface of the brain and part of the basal ganglia and the internal capsule via four segments (M1, M2, M3, and M4).

What does a stroke on right side of brain affect?

Right Brain If the stroke occurs in the right side of the brain, the left side of the body will be affected, producing some or all of the following: Paralysis on the left side of the body. Vision problems. Quick, inquisitive behavioral style.

What are the symptoms of a frontal lobe stroke?

Here are some of the most common symptoms of frontal lobe stroke:

• Hemiparesis or hemiplegia. This involves weakness or paralysis on one side of the body, usually the opposite side of the stroke.
• Speech difficulties.
• Dysphagia.
• Ataxia.
• Incontinence.
• Impaired spatial reasoning.
• Vascular dementia.
• Behavior changes.

What does left brain stroke affect?

Left Brain If the stroke occurs in the left side of the brain, the right side of the body will be affected, producing some or all of the following: Paralysis on the right side of the body. Speech/language problems. Slow, cautious behavioral style.

What does a stroke feel like in your head?

For instance, some individuals may feel pain in their head due to a headache. Others may not feel any physical sensations but may struggle to speak, which can lead to emotions of panic and confusion.

Is left or right-sided stroke more common?

Introduction. Several hospital-based studies have reported that left-sided strokes are more frequent than right-sided strokes. A predilection for the left side may be explained by characteristics of the atherosclerotic plaque in the left carotid artery or by anatomy.

What are the symptoms of a right brain stroke?

Symptoms

• Muscle weakness on the left side of the body.
• Vision problems, including problems seeing from the left side of each eye.
• Hearing problems.
• Sensory changes on the left side of the body.
• Problems with depth perception or directions.
• Problems with balance.
• A feeling of spinning when a person is still.
• Memory problems.

Is a right side stroke worse than a left side?

In our study, clinical ischemic strokes and TIAs were more frequently left-sided than right-sided. This was different from the distribution of infarcts on MRI. This suggests that left-sided strokes are recognized better or perceived as more severe, whereas right-sided strokes are missed.

What are three symptoms of frontal lobe damage?

Some potential symptoms of frontal lobe damage can include:

• loss of movement, either partial (paresis) or complete (paralysis), on the opposite side of the body.
• difficulty performing tasks that require a sequence of movements.
• trouble with speech or language (aphasia)
• poor planning or organization.

What is a temporal lobe stroke?

Temporal lobe strokes are caused when a blood vessel in the temporal lobe becomes clogged (ischemic stroke), or bursts in this area (hemorrhagic stroke). Blood is rich in oxygen, which fuels cellular activity. When the brain doesn’t receive a sufficient supply of blood, those brain cells start to die.

Where is a stroke headache located?

Stroke-Related Headaches Oftentimes, the area affected by the headache is directly related to where the stroke occurs. For example, a blocked carotid artery can cause a headache on the forehead, while a blockage towards the back of the brain can cause a headache towards the back of the head.

What side of face is affected by stroke?

Face drooping is one of the most common signs of a stroke. One side of the face may become numb or weak. This symptom may be more noticeable when the patient smiles. A lopsided grin could indicate that the muscles on one side of the face have been affected.

Which part of the head is most vulnerable?

We find that head angular acceleration and brain tissue strain resulting from an input force can vary by orders of magnitude based on impact location on the skull, with the mandible as the most vulnerable region.

How many areas of the brain are affected by stroke?

There are 9 major areas of the brain that can be affected by stroke. Each area of the brain controls different functions, and everyone’s brain is wired a bit differently. Therefore, the effects of a stroke greatly vary from person to person.

What are the symptoms of a stroke?

A stroke might affect control of the muscles in your mouth and throat, making it difficult for you to talk clearly, swallow or eat. You also may have difficulty with language, including speaking or understanding speech, reading, or writing. Memory loss or thinking difficulties. Many people who have had strokes experience some memory loss.

What happens to the brain after a stroke?

Depending on the area of the brain affected by stroke, this damage will cause changes in certain sensory, motor, or cognitive functions. Although it’s impossible to revive dead brain cells, recovery is possible through neuroplasticity. This process allows healthy parts of the brain to take over the functions damaged by stroke.

Where can I find information about stroke in the US?

Public health officials and other health professionals can find up-to-date facts, statistics, maps, and other information related to stroke in these reports and resources: Centers for Disease Control and Prevention, National Center for Health Statistics. Multiple Cause of Death 1999–2019. CDC WONDER Online Database website.
