What causes pontine hemorrhage?
What causes pontine hemorrhage?
Pontine hemorrhage is usually caused by uncontrolled systemic hypertension, resulting in a sudden loss of consciousness, quadriparesis, and pinpoint pupils.
What is an ipsilateral stroke?
In conclusion, ipsilateral hemiparesis can develop as a result of a new stroke after a previous stroke on the opposite side. The mechanism involved is thought to be functional reorganization of the ipsilateral hemisphere.
What is medullary hemorrhage?
The medulla oblongata is a rare site of parenchymal hemorrhage, and the clinical features, optimal treatment, and prognosis of this condition are not well known. Parenchymal hemorrhage of the medulla has been attributed to anticoagulant therapy,1 vascular malformation, 2,3 or a caudal extension of a pontine hemorrhage.
What is the meaning of 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). Enlarge.
Is pontine hemorrhage a stroke?
A stroke occurs when the supply of blood to the brain is compromised by either a clogged artery (called an ischemic stroke) or burst artery (called a hemorrhagic stroke). When stroke happens in the pons, which is the upper section of the brain stem, it’s called a pontine stroke.
What is ipsilateral weakness?
We defined ipsilateral weakness as paresis ipsilateral to the side of the cerebral ischemic or hemorrhagic event with an acute presentation. Patients who had remote infarcts with new neurological weakness were also included.
Are stroke symptoms contralateral or ipsilateral?
A stroke in this vascular distribution often results in contralateral paralysis or weakness (hemiparesis/hemiplegia), sensory loss and visual field loss (homonymous hemianopsia) (Adams, 1997). Middle cerebral artery involvement is very common while anterior cerebral artery strokes are less common (Teasell, 1998).
What causes UMN signs?
Causes
- Lou Gehrig’s disease (amyotrophic lateral sclerosis, or ALS)
- Primary lateral sclerosis (PLS)
- Traumatic brain injury.
- Spinal cord injury.
- Multiple sclerosis.
- Stroke.
- Huntington’s disease.
Where is pontine in the brain?
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 is a brain hemorrhage?
A brain hemorrhage is a type of stroke. It’s caused by an artery in the brain bursting and causing localized bleeding in the surrounding tissues. This bleeding kills brain cells.
What happens if you have a hematoma on your brain?
Hematomas can result in excess pressure and/or swelling of the brain, and in the worst cases can lead to death. Symptoms Related to Brain Bleeds. Symptoms and signs of brain bleeding vary depending on the extent of the tissue affected, the extent of the bleeding, and the location of the bleeding.
What is intracerebral and intraventricular hemorrhage?
Intracerebral hemorrhage: This bleeding occurs in the lobes, pons and cerebellum of the brain (bleeding anywhere within the brain tissue itself including the brainstem). Intraventricular hemorrhage: This bleeding occurs in the brain’s ventricles, which are specific areas of the brain (cavities) where cerebrospinal fluid is produced.
How can I minimize my risk for a brain hemorrhage?
Because the majority of brain hemorrhages are associated with specific risk factors, you can minimize your risk in the following ways: Treat high blood pressure. Studies show that 80% of cerebral hemorrhage patients have a history of high blood pressure.
