What is asomatognosia?
A lack of interest in or recognition of one or more parts of one’s own body
What is anosognosia?
Denial of one’s illness
What are some effects of damage to the parietal lobe?
Somatosensory agnosias, apraxia, contralateral neglect, Gerstmann’s syndrome
What is apraxia?
Inability to perform purposeful, skilled movements not due to motor, sensory, or language impairment
What is contralateral neglect also known as?
Unilateral neglect and hemispatial neglect
What type of apraxia involves an inability to make precise, coordinated movements?
Limb-kinetic apraxia
What is ideomotor apraxia?

What typically causes contralateral neglect?
Damage to the right (nondominant) parietal lobe
What are the symptoms of Gerstmann’s syndrome?
