Risk of late radiation necrosis more than 5 years after stereotactic radiosurgery.

Objective: Radiation necrosis (RN) is a well-recognized late complication most commonly occurring within 2 years of stereotactic radiosurgery (SRS); however, late RN (LRN), RN occurring or recurring > 5 years after SRS, has been poorly described. This study analyzes the incidence of and risk factors for LRN occurring > 5 years after SRS.

Methods: This retrospective analysis included patients treated with linear accelerator-based SRS for tumors or arteriovenous malformations with > 5 years of clinical and serial MRI follow-up.

Assistive technology: Visual mapping combined with mobile software can enhance quality of life and ability to carry out activities of daily living in individuals with impaired memory.

Background: There is growing evidence that assistive digital technology can enhance quality of life (QOL) for individuals with various forms of cognitive impairment, including dementia.

Objective: Assess whether the use of a visual mapping software program to manage activities of daily living would have a positive impact on QOL scores and on cognitive scores in a group of dementia residents in an adult living community.

Methods: We compared quality-of-life scores and cognitive function scores before and after using the assistive technology for three months.
