For people with brain tumors, radiation can be an effective treatment because chemotherapy is often less effective due to the blood–brain barrier. [ citation needed ] Unfortunately for some patients, as time passes, people who received radiation therapy may begin experiencing deficits in their learning, memory, and spatial information ...

Acute and late radiation damage to the central nervous system (CNS) may lead to changes in motor function and behavior or neurological disorders. Radiation and synergistic effects of radiation with other space flight factors may affect neural tissues, which in turn may lead to changes in function or behavior. Data specific to the spaceflight ...
Temporal lobe necrosis is a late-stage and serious complication usually occurring in persons who have undergone radiation treatment for nasopharyngeal carcinoma (NPC). It is rather rare and occurs in 4-30% of patients who receive radiation treatment for NPC. Many patients who experience temporal lobe necrosis are asymptomatic.
Radiation necrosis Radiation necrosis is the death of healthy tissue near the irradiated site. It is a type of coagulative necrosis that occurs because the radiation directly or indirectly damages blood vessels in the area, which reduces the blood supply to the remaining healthy tissue, causing it to die by ischemia, similar to what happens in ...
Acute necrotizing encephalopathy (ANE) or sometimes necrotizing encephalitis or infection-induced acute encephalopathy (IIAE) is a rare type of brain disease (encephalopathy) that occurs following a viral infection. [4] Most commonly, it develops secondary to infection with influenza A, influenza B, and the human herpes virus 6. ANE can be ...
Osteoradionecrosis (ORN) is a serious complication of radiation therapy in cancer treatment where radiated bone becomes necrotic and exposed. [1] ORN occurs most commonly in the mouth during the treatment of head and neck cancer, and can arise over 5 years after radiation. [2]
