a neurological syndrome manifested by a combination of several cognitive impairments, most often occurring when the left parietal lobe of the brain is damaged. The main symptoms of the syndrome are:
Autotopagnosia – impairment of the ability to correctly identify and localize parts of one’s own body (for example, the patient cannot indicate where the right hand or left foot is). Finger agnosia – inability to distinguish between fingers on the hands, sometimes the patient cannot indicate which finger is on which hand. Graphic agnosia – impairment of the ability to draw or copy geometric shapes and other images. Agraphia – loss of the ability to write when preservation of motor functions. Gerstmann syndrome often occurs when the angular gyrus (gyrus angularis) in the left hemisphere of the brain is affected, which is associated with impaired connections between the visual, motor and tactile cortex.
