This condition is frequently accompanied by the feeling of being disempowered about ones body part. Background: In addition to instances of asomatognosia in which patients deny ownership of a specific part, this condition is also associated with the following: anosognosia (unawareness or denial of illness), anosodiaphoria (indifference to illness), autopagnosia (inability to localize and name body parts), and asymbolia for pain (absence of typical reactions to pain). and transmitted securely.
