New Zealand violinist Jenny (Jennifer) Banks dies aged 42 following a period of illness with dementia, multiple outlets report. She was diagnosed with behavioural variant frontotemporal dementia in 2020, according to NZ Herald. Stuff describes Banks as internationally acclaimed and notes that her career is cut short by the condition. Reports say Banks performed around the world, establishing a reputation as a professional violinist before her illness affected her ability to continue working. Both sources frame her death as occurring after a dementia battle and do not attribute the cause beyond the dementia condition described. The accounts also agree on her age at death and the general timeline beginning with the 2020 diagnosis.
