Parietal signs at the bedside - apraxia
	• Apraxia – inability to conceptualize or mimic a movement, even though the patient can make the necessary movements – patients with parietal lesions cannot mimic how to use a toothbrush but they can use one.  They cannot orient their hands or set a grip in a movement. • Constructional apraxia - they cannot duplicate block designs, and have great difficulty copying drawings. • Optic ataxia – difficulty reaching to objects in space or finding them with saccades.
