  2. Radiation-induced cognitive decline - Wikipedia

    en.wikipedia.org/wiki/Radiation-induced...

    Radiation of 100 mGy to the head at infancy resulted in the beginning appearance of statistically significant cognitive-deficits in one Swedish/radiation-therapy follow-up study. [5] Radiation of 1300-1500mGy to the head at childhood was similarly found to be roughly the threshold dose for the beginning increase in statistically significant ...

  3. Chronic radiation syndrome - Wikipedia

    en.wikipedia.org/wiki/Chronic_radiation_syndrome

    Dose rates high enough to cause the acute form (> ~0.1 Gy/h) are fatal long before onset of the chronic form. The lower threshold for chronic radiation syndrome is between 0.7 and 1.5 Gy , at dose rates above 0.1 Gy/yr. [ 3 ] This condition is primarily known from the Kyshtym disaster , where 66 cases were diagnosed.

  4. Osteoradionecrosis - Wikipedia

    en.wikipedia.org/wiki/Osteoradionecrosis

    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]

  5. Brain injury - Wikipedia

    en.wikipedia.org/wiki/Brain_injury

    Radiation and chemotherapy can lead to brain tissue damage by disrupting or stopping blood flow to the affected areas of the brain. This damage can cause long term effects such as but not limited to; memory loss, confusion, and loss of cognitive function. The brain damage caused by radiation depends on where the brain tumor is located, the ...

  6. Acute radiation syndrome - Wikipedia

    en.wikipedia.org/wiki/Acute_radiation_syndrome

    Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months.

  7. Radiation therapy - Wikipedia

    en.wikipedia.org/wiki/Radiation_therapy

    Most side effects are predictable and expected. Side effects from radiation are usually limited to the area of the patient's body that is under treatment. Side effects are dose-dependent; for example, higher doses of head and neck radiation can be associated with cardiovascular complications, thyroid dysfunction, and pituitary axis dysfunction ...

  8. Radiation damage - Wikipedia

    en.wikipedia.org/wiki/Radiation_damage

    Radiation damage is the effect of ionizing radiation on physical objects including non-living structural materials. It can be either detrimental or beneficial for materials. Radiobiology is the study of the action of ionizing radiation on living things, including the health effects of radiation in humans.

  9. Ataxia - Wikipedia

    en.wikipedia.org/wiki/Ataxia

    Ataxia (from Greek α- [a negative prefix] + -τάξις [order] = "lack of order") is a neurological sign consisting of lack of voluntary coordination of muscle movements that can include gait abnormality, speech changes, and abnormalities in eye movements, that indicates dysfunction of parts of the nervous system that coordinate movement, such as the cerebellum.
