Global aphantasia is a complete absence of voluntary imagery across every sense, sometimes called total aphantasia. It can be congenital or acquired.
Ten years after aphantasia was named, Adam Zeman argues it likely has several subtypes and that most abilities are spared, with memory for one's own past differing most. He urges an open mind in this young field.

Researchers define aphantasia as the absence of voluntary sensory imagery, often extending beyond vision to other modalities. This formal definition establishes a standardized framework for classifying multisensory and global imagery deficits.

Researchers propose defining aphantasia as the absence or reduction of voluntary sensory imagery across any modality. This unified terminology avoids a proliferation of new terms while acknowledging that imagery deficits can be specific or multisensory.
