What is meant by encephalomalacia and gliosis?
Leukoencephalomalacia refers to encephalomalacia of the white matter. Areas of encephalomalacia are often surrounded by a rim of gliosis, which is the proliferation or hypertrophy of glial cells in response to injury.
What is occipital gliosis?
Parieto-occipital (PO) gliosis is a common sequela following perinatal asphyxia and neonatal hypoglycaemia. Though the location of cerebral lesions in patients with neonatal hypoglycaemia and perinatal asphyxia is not different, subtle differences may be observed (Barkovich, 2005).
What is occipital encephalomalacia?
Encephalomalacia refers to softening of the brain’s tissue due to hemorrhage or inflammation. It is one of the most serious types of brain injury. It can affect specific parts of the brain, or can be more widespread, and encephalomalacia can lead to complete dysfunction of the part of the brain that is affected.
What causes occipital encephalomalacia?
The causes of encephalomalacia are different types of trauma to the brain, a cerebral hemorrhage, or a cerebral ischemia. Most times when we encounter encephalomalacia, it was caused by some type of birth injury, either during the labor and delivery of a child, or the treatment shortly thereafter.
What are the symptoms of gliosis?
Gliosis occurs when your body creates more or larger glial cells (cells that support nerve cells). These new glial cells can cause scars in your brain that impact how your body works….Symptoms may include:
- Memory loss or impairment.
- Personality changes.
- Trouble with cognitive function.
Is encephalomalacia considered brain damage?
Encephalomalacia, a serious form of brain damage, is a softening of brain tissue that is caused by an injury or inflammation. The cerebral softening sometimes occurs in one part of the brain and then spreads to adjacent areas.
What does gliosis mean?
Gliosis, also called astrocytic gliosis or astrocytosis, is a common term that refers to the reactive astrocytic response to a brain injury or insult. Almost all brain lesions have a component of gliosis, even with different glial pathologies.
