Hemispatial neglect can have a wide range in terms of what the patient neglects. The first range of neglect, commonly referred to as "egocentric" neglect, is found in patients who neglect their own body or personal space. [19] These patients tend to neglect the opposite side of their lesion, based on the midline of the body, head, or retina. [20]
Psychologists formerly characterized dyschiric patients to be unable to discriminate or report external stimuli. This left the patients incapable of orienting sensory responses in their extrapersonal and personal space. Patients with dyschiria are unable to distinguish one side of their body in general, or specific segments of the body.
Hemimotor neglect or simply motor neglect is a neuropsychological condition that occurs after damage to one hemisphere of the brain, characterized by a failure of spontaneous use of upper and lower limbs on one side of body. It occurs in the absence of paralysis, pyramidal syndromes, extrapyramidal symptoms, strength and primary sensory deficit ...
Patients with a right hemisphere lesion show left sided neglect in other modalities and fail to respond to the left contralateral nostril, thus the representational theory is supported. It was suggested that since the olfactory sensory pathways to the cerebral hemispheres were not crossed, a neglect should have occurred on the right side if a ...
In visual allochiria, objects situated on one side of the visual field are perceived in the contralateral visual field. [15] In one of the two cases ever recorded, the visual impression received by the right open eye was regularly referred to the left eye, and the patient maintained that she perceived the impression with the left eye that in fact was shut.
Evidence indicates that damage to the right hemisphere often results from a stroke or pre-existing hemispatial neglect, or inattention to the left visual field (Antoniello, 2016) (Keenan, 2004). Individuals who suffer from somatoparaphrenia, a specific form of asomatognosia, ignore or deny ownership of a body part contralateral to the brain ...
Bálint's syndrome symptoms can be quite debilitating since they impact visuospatial skills, visual scanning and attentional mechanisms. [8] Since it represents impairment of both visual and language functions, it is a significant disability that can affect the patient's safety—even in one's own home environment, and can render the person incapable of maintaining employment.

Patients with this form of aphasia may present with a contiguity disorder in which they have difficulty combining linguistic elements. For dynamic aphasia, this is most apparent when the patient is asked to sequence at the sentence level whereas for other aphasias contiguity disorder can be seen at the phoneme or word level.
