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]
