Patients with<unk>  have an impaired sense of touch<unk> , 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. It is oftentimes associated with dyschiria, also known as a form of unilateral neglect or hemispatial neglect. The term<unk>  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:<unk> , allochiria and synchiria, of which<unk>  is considered to be the primary stage. Patients suffering from<unk>  would suffer deficits in sensory, motor and introspective areas of consciousness. The symptoms are associated with hysteria, spinal lesions and unilateral neglect syndrome. In Greek terminology,<unk> ” or “χεiρ” means hand, while the "a-" prefix means "without" or "not". However, in actual clinical practice,<unk>  is also referred to the inability to localize stimuli from other parts of the body.
