What does a stroke in the pons affect?

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).

What happens when the pons is damaged?

Pons also relays sensory information and signals governing sleep patterns. If pons is damaged, it may cause loss of all muscle function except for eye movement.

What is paramedian pontine infarction?

Conclusions: Paramedian pontine infarcts, which are usually due to thrombosis of perforating arteries, presented with a faciobrachial dominant hemiparesis with dysarthria, somatosensory disturbance, and horizontal gaze abnormalities.

What does the pons area of the brain control?

The pons, while involved in the regulation of functions carried out by the cranial nerves it houses, works together with the medulla oblongata to serve an especially critical role in generating the respiratory rhythm of breathing. Active functioning of the pons may also be fundamental to rapid eye movement (REM) sleep.

What does the pons control?

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 are the 3 functions of the pons?

The pons powers the functions of the head and face The brainstem is made up of three sections, and carries vital information to the body. The pons relays information about motor function, sensation, eye movement, hearing, taste, and more.

How does the pons regulate sleep?

Are there any reports of paramedian pontine infarctions?

Background and Purpose There have been few reports of pontine syndromes secondary to paramedian pontine infarctions. To clarify the clinicotopographical correlation and prognosis of paramedian pontine infarct syndromes, we analyzed the clinical signs and their association with MRI findings.

What are the side effects of a pontine stroke?

Side Effects of Pontine Stroke. 1 Impaired breathing (and required life support) 2 Loss of consciousness (coma) 3 Locked-in syndrome (the entire body becomes paralyzed except for the eyes) 4 Visual and hearing disturbances. 5 Changes in sensation. 6 Weakness in the limbs. 7 Swallowing and speech difficulty.

How many patients have acute isolated pontine infarct?

In all patients CT, MRI and magnetic resonance angiography (MRA) were performed during the hospitalization. On clinico-radiological analysis … We sought clinical and radiological findings of 150 consecutive patients with acute isolated pontine infarct who were admitted to our Stroke Unit over 6 years.

What are the symptoms of a stroke in the pons?

Strokes that occur in the pons can cause a variety of serious symptoms, despite the small area of damage involved. Some of the symptoms of a pontine stroke include a combination of the following: Balance difficulty. Vertigo (spinning sensation) Dizziness. Double vision. Loss of coordination.
