Parietal lobe syndrome

From WikiLectures

Parietal lobe syndrome occurs when the postcentral gyrus is affected , when someesthetic functions are impaired [1].  Among the most common causes that lead to the development of the syndrome are ischemic vascular events, expansive processes and brain atrophy ( Alzheimer's ). [2]

Symptoms[1][edit | edit source]

  • 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, [2]
  • bilateral negative blink reflex, [2]
  • nystagmus in the direction away from the lesion [2]
