Parietal lobe syndrome

Parietal lobe syndrome occurs when the postcentral gyrus is affected, when someesthetic functions are impaired. Among the most common causes that lead to the development of the syndrome are ischemic vascular events, expansive processes and brain atrophy ( Alzheimer's ).

Symptoms

 * Astereognosia – inability to recognize objects by touch.
 * Topagnosia – inability to localize sensitive stimuli.
 * Autotopagnosia – inability to recognize parts of one's own body.
 * Agraphestehsia – inability to identify numbers and letters that are written on the skin by gentle scratching.
 * Alexia, agraphia, conduction aphasia in dominant hemisphere lesions.
 * Anosognosia, neglect syndrome in a disorder of the non-dominant hemisphere.
 * In addition, it may arise:
 * apraxia,
 * contralateral disturbance of vibration and position senseation with a relatively small disturbance of pain and heat sensation
 * contralateral hemianopsia in a lesion of the deep parts of the white matter of the parietal lobe,
 * bilateral negative blink reflex,
 * nystagmus in the direction away from the lesion
