Radiation-induced brain edema (RIBE) is a potentially life-threatening complication of brain tissue radiation and is characterized radiation necrosis, endothelial cell dysfunction, increased capillary permeability, and breakdown of the blood–brain barrier. [13] Symptoms include headache, seizure, psychomotor slowing, irritability, and focal ...
However, these treatments do produce side effects; most often including nausea, the breakdown of the immune system, and fatigue. Hair loss can occur from both chemotherapy and radiation, but usually grows back after chemotherapy has ceased. Steroids such as Decadron may be required to treat swelling in the brain. Decadron can lead to weight ...
Symptoms of a brainstem stroke frequently include sudden vertigo and ataxia, with or without weakness. Brainstem stroke can also cause diplopia, slurred speech and decreased level of consciousness. A more serious outcome is locked-in syndrome. [citation needed]
In PRES related to medications, there may be an interval of weeks to months between the initiation of the treatment and the development of PRES. [1] [3] After a hematopoietic stem cell transplantation (bone marrow transplant) the risk of PRES is approximately 8%, whereas the risk is lower (0.4-6%) after a solid organ transplant. [3]
Severely raised ICP, if caused by a unilateral space-occupying lesion (e.g. a hematoma) can result in midline shift, a dangerous sequela in which the brain moves toward one side as the result of massive swelling in a cerebral hemisphere. Midline shift can compress the ventricles and lead to hydrocephalus. [21]
Lack of CSF pressure and volume can allow the brain to sag and descend through the foramen magnum (large opening) of the occipital bone, at the base of the skull. The lower portion of the brain is believed to stretch or impact one or more cranial nerve complexes, thereby causing a variety of sensory symptoms. Nerves that can be affected and ...
The symptoms depend on the cause of the blockage, the person's age, and how much brain tissue has been damaged by the swelling. [11] In infants with hydrocephalus, CSF builds up in the central nervous system (CNS), causing the fontanelle (soft spot) to bulge and the head to be larger than expected. Early symptoms may also include: [11]
High-altitude cerebral edema (HACE) is a medical condition in which the brain swells with fluid because of the physiological effects of traveling to a high altitude. It generally appears in patients who have acute mountain sickness and involves disorientation, lethargy, and nausea among other symptoms. It occurs when the body fails to ...
