What causes a pontine stroke?
In rare instances, a stroke involving the pons , typically called a pontine stroke , maybe the result of an injury to an artery caused by sudden head or neck trauma.
What is a pontine?
Listen to pronunciation. (PON-teen) Having to do with the pons (part of the central nervous system, located at the base of the brain, between the medulla oblongata and the midbrain).
What happens if there is damage to the pons?
Harvey explained it in this way: “ If injury in one side of the pons causes weakness on the opposite side of the body and facial and eye movement weakness on the same side of the body, then when stroke hits both sides of the pons , you’re going to get weakness on both sides of the body, paralysis on both sides of the
What does the Pontine control?
The pons is involved in many autonomic and sensory functions including arousal, respiratory processes, fine motor control , equilibrium, muscle tone, and the Circadian cycle (specifically regulating sleep).
What’s a pontine stroke?
A pontine cerebrovascular accident (also known as a pontine CVA or pontine stroke ) is a type of ischemic stroke that affects the pons region of the brain stem. A pontine stroke can be particularly devastating and may lead to paralysis and the rare condition known as Locked-in Syndrome (LiS).
Can you recover from central pontine Myelinolysis?
Outlook for Central Pontine Myelinolysis CPM was originally believed to have a mortality rate of 50 percent, but early diagnosis has improved the outlook. Although some people still die as a result of the damage sustained, many people with CPM are able to recover .
What is the Pons responsible for?
The pons contains nuclei that relay signals from the forebrain to the cerebellum, along with nuclei that deal primarily with sleep, respiration, swallowing, bladder control, hearing, equilibrium, taste, eye movement, facial expressions, facial sensation, and posture.
What happens if the midbrain is damaged?
Damage to the midbrain can result in a wide variety of movement disorders, difficulty with vision and hearing, and trouble with memory. Because the midbrain houses the hypothalamus, it also plays a major role in automatic body functions.
What part of the brain is the Pontine?
The pons is a portion of the brain stem, located above the medulla oblongata and below the midbrain.
What would be affected by a brain injury in the pons?
If pons is damaged , it may cause loss of all muscle function except for eye movement.
Can a person live with brain stem damage?
What happens when you damage your brain stem . When an accident causes brain stem damage , the affects can be devastating. In fact, destruction of the midbrain, pons, or medulla oblongata causes “ brain death”, and the unfortunate victim of the injury cannot survive .
What behaviors would be affected if the brain stem was damaged?
A brain stem injury can cause dizziness or lack of motor function, with more severe cases resulting in paralysis, coma, or death. Treatment can be extremely expensive, and many victims are unable to work while coping with a brain stem injury.
How does the Pons affect sleep?
The brain stem (especially the pons and medulla) also plays a special role in REM sleep ; it sends signals to relax muscles essential for body posture and limb movements, so that we don’t act out our dreams.
What side of the brain controls sleep?
Neurons in a part of the hypothalamus called the ventrolateral preoptic nucleus (VLPO) connect directly to the many arousal-promoting centers. Rather than stimulating activity in these areas, signals from VLPO neurons inhibit their activity. By shutting down the arousal centers, the VLPO promotes sleep .
What is the pons in psychology?
Pons : n. a structure on the brain stem that lies above the medulla and regulates sleep, arousal, consciousness, and sensory processes. Pons is Latin for bridge. It consists of nerve fibers that connect the cerebrum and the cerebellum, and bridges sensory information between the left and right hemispheres of the brain.
