A Parietal lobe lesion presented with Sensory seizures, motor deficits' visual disorders, no touch perception on opposite side and on simultaneous bilateral touch. This is associated with
(A) Unilateral parietal lobe dysfunction Unilateral parietal lobe dysfunction (Right or left)Dominant (left) parietal lobe dysfunction (in most right- handed and some left handed patients)Non-dominant (right) parietal lobe dysfunctionBilateral parietal lobe dysfunction* Sensory deficits (asterognosis, agraphesthesia, sensory seizures)* Motor deficits (mild hemiparesis)* Visual disorders (homonymous hemianopia, inferior quadrantanopia, visual inattention)* Contralateral neglect (more obvious for right sided lesions)* Constructional and dressing apraxia* Language disorders (aphasia, alexia)* Gertsmann syndrome (dyscalculia, dysgraphia, finger agnosia, right-left confusion)* Apraxia* Hemispatial neglect* Sensory and visual inattention* Constructional and dressing apraxia (greater severity for right sided lesions)* Visuospatial disorientation* Balint syndrome (optic ataxia, oculomotor apraxia, simultanagnosia)# Symptoms & Signs of Parietal lobe dysfunction: Paroxysmal localized paraesthesia (tingling sensations/'pins and needles'), affecting the contralateral side of the body. Also known as sensory seizures. Sensory deficits to the contralateral side can occur, leading to astereognosis, agraphesthesia, loss of proprioception, vibration and fine touch. Primary sensory modalities may return after a short time, however discrimination between sensations may not. Mild hemiparesis could also occur.
