Gerstmann’s syndrome

= lesions affecting the dominant (usually left) parietal lobe (CVA / space occupying lesion etc.)

Clinical features are:

• Acalculia (when asked to do serial 7s)
• Agraphia
• Left-right disorientation
• Finger agnosia (the inability to recognize, name or appropriately move fingers)

And non-specific parietal-lobe findings, that can occur when either lobe is involved:

• lower quadrantic hemianopia
• astereognosis
