Synopsis

Covers the whole plot, including the ending.

Left Neglected explores the disorienting experience of hemispatial neglect, a neurological condition where the brain ignores half of reality after a stroke. The book illustrates how this deficit changes one's perception of self, family, and the world, forcing a re-evaluation of control, success, and what a 'normal' life means. It looks at the unseen work of recovery and caregiving, showing the brain's ability to adapt and find meaning after loss. Ultimately, it advocates for embracing a 'new normal' shaped by trauma and rehabilitation.
