Aphantasia: When Your Mind's Eye Sees Nothing

Sassy Smith, a 56-year-old therapist, lives with aphantasia, the inability to create mental images, and a related condition called severely deficient autobiographical memory (SDAM). This means she cannot visualize her childhood, her wedding day, or even the faces of loved ones when they are not present. Smith discovered these conditions in 2019, which helped her understand lifelong difficulties with memory recall and social recognition. She notes that if she doesn't see people regularly, she may stop recognizing them.

Research published in the journal Cortex, utilizing ultra-high-field functional MRI at the Paris Brain Institute, has shed light on the neurological underpinnings of aphantasia. The study observed less communication between key brain areas responsible for memory and visual processing in individuals with aphantasia, despite these areas activating. Professor Adam Zeman, a neurologist at Exeter University who coined the term 'aphantasia,' believes these conditions are cognitive differences related to how the brain is 'wired' rather than impairments. He suggests a genetic predisposition is likely, though cases resulting from head injuries or strokes are also documented.
