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 ...
The brain damage caused by radiation depends on where the brain tumor is located, the amount of radiation used, and the duration of the treatment. Radiosurgery can also lead to tissue damage that results in about 1 in 20 patients requiring a second operation to remove the damaged tissue. [27] [28]
While DNA damage happens frequently and naturally in the cell from endogenous sources, clustered damage is a unique effect of radiation exposure. [41] Clustered damage takes longer to repair than isolated breakages, and is less likely to be repaired at all. [42] Larger radiation doses are more prone to cause tighter clustering of damage, and ...
Experts explain if cell phones cause brain cancer. After a WHO-commissioned report, oncologists weigh in on cell phone radiation’s effects on the human body.
Radiation poisoning, also called "radiation sickness" or a "creeping dose", is a form of damage to organ tissue due to excessive exposure to ionizing radiation. The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period, though this also has occurred with long-term exposure to low-level radiation.
The new British research is the first to reveal striking differences in areas of the brain based on scans taken before and after a coronavirus infection. Even mild COVID-19 is linked to brain ...
A third type of tissue in the brain is the vasculature which exhibits a comparable vulnerability for radiation damage to that found elsewhere in the body. [38] Radiation-induced damage to oligodendrocytes and endothelial cells of the vasculature accounts for major aspects of the pathogenesis of brain damage that can occur after high doses of ...
How Covid infection affects the brain: Even mild cases of Covid-19 are associated with subtle tissue damage and accelerated losses in brain volume, study shows.
