Hemispatial Neglect (and Autosomatagnosia)
Published in Alexander R. Toftness, Incredible Consequences of Brain Injury, 2023
As a start, asomatognosia is the general feeling of nothingness surrounding physical parts, in other words, a lack of awareness of one's own body. If you've ever had the feeling that a part of your body has stopped existing—maybe you laid on top of your arm for too long and no longer know where it is located thanks to a complete feeling of numbness—you've had temporary asomatognosia. Asomatognosia and neglect often happen in the same person at the same time, but this is not always true—either one is possible without the occurrence of the other (Jenkinson et al., 2018). It gets even more complicated, because there are at least two subtypes of asomatognosia.

Explanation: Asomatognosia, which is the lack of awareness of the condition of all or part of the body, occurs usually when there is an inherent insult to the nondominant parietal lobe of the body. Other associated signs and symptoms that might occur due to an insult to the dominant parietal lobe include dysgraphesthesia and Wernicke’s or Broca’s aphasia.
The behavioral presentation of an individual with a disordered sense of self

Numerous case studies associated with “disorders of the self” have been presented in the literature and, most thoroughly in The Lost Self (1). These disorders are associated with a diminished sense of self that involve denial of characteristics and attributes of the “self.” Of note, these disorders of the self are generally associated with impairments in the right hemisphere, and particularly the right inferior parietal lobe which is considered to be part of an “association” area (1–4). To date disorders of the self have primarily been conceptualized as disorders of “self-awareness” that involve the inability of individuals to be aware of (or the tendency to deny) personal characteristics (i.e., physical, psychological, social). Examples include such diverse disorders as anosognosia (i.e., unawareness of impairments; 5), alexithymia (i.e., inability to identify emotions; 6), asomatognosia (i.e., denial of body parts as belonging to the self; 1), mirror misidentification disorder (i.e., inability to recognize one’s own reflection; 7), Capgras’ syndrome (i.e., belief that family members are imposters; 8, 9), and schizophrenia (i.e., lack of recognition of internal thoughts as belonging to the self; 10).
