CH 5 right hemisphere deficits, attentional, and neuropsychiatric deficits following right-hemisphere damage

Attentional Deficits

Hemispatial and hemibody neglects, sustained and selective attention deficits, Neglect

Neglect

Inability to attend to sensory stimuli

Inability to attend to sensory stimuli from one side of their body

hemibody neglect

Inability to attend to sensory stimuli from one side of the environment

hemispatial neglect

Mild cases of hemispatial neglect may be known as

extinction

In severe cases of neglect

individuals may be unable to recognize the existence of the neglected world via vision, auditory, and olfactory information

Side unattended to or unrecognized is

the side of the body/environment that is contralateral to the lesioned hemisphere

Asomatagnosia

When the individual is unable to perceive their own body parts as being part of themselves, not hemibody neglect

Asomatagnosia paired with somatophrenia

the delusion that the body part belongs to someone else; can have intact motor function but unutilized

Selective and Sustained Attention

Necessary for attending, processing, and understanding, language, important social cues, and social interactions

Neuropsychiatric Disorders importance

understand and recognize disorders that may present alongside and interact with deficits and disorders that more highly concern SLPs

Neuropsychiatric Disorders

Anosognosia, Depression, Capgras Delusion, Fregoli delusion, Visual hallucinations, Paranoid hallucinations

Anosognosia

An individual's inability to recognize/realize they have deficits

Depression

Common in any population following disease, surgery, stroke, or trauma

Capgras delusion
