Achiria, also referred to as "Simple Allochiria", is a neurological disorder in which a patient is unable to recognise or perceive one side of their body.^[1] It is oftentimes associated with dyschiria, also known as a form of unilateral neglect or hemispatial neglect. The term achiria is seldom used in modern scientific literature.

Psychologists in the past defined dyschiria as the inability of patients to distinguish the side of which a given stimulus is generated from. There are three forms of dyschiria: achiria, allochiria and synchiria, of which achiria is considered to be the primary stage.^[2]

Patients with achiria would have deficits in sensory, motor and introspective areas of consciousness. The symptoms are associated with hysteria, spinal lesions and unilateral neglect syndrome. In Greek terminology, "chiria" or "χεiρ" means hand, while the "a-" prefix means "without" or "not".^[3][4] However, in actual clinical practice, achiria is also referred to the inability to localize stimuli from other parts of the body.
