Unilateral spatial neglect due to right frontal lobe haematoma.

Unilateral spatial neglect due to right frontal lobe haematoma.

Two patients with unilateral spatial neglect caused by right frontal lobe lesions underwent cerebral blood flow studies. A 54-year-old, right-handed woman developed left hemiplegia and frontal lobe neglect associated with cerebral haemorrhage after surgical excision of a frontal tumour. A 66-year-old, right-handed woman developed a haemorrhage in the right frontal lobe caused by rupture of an a...

Preserved leftward movement in left unilateral spatial neglect due to frontal lesions.

Three patients with left unilateral spatial neglect after predominantly frontal lobe lesions were asked to extend a horizontal line leftwards to double its original length. In this line extension task, they readily executed movements in or towards the contralesional left space. They performed the task in the left and right hemispaces as well as in the midline. The mean extension lengths did not...

Ipsilateral hyperschematia without spatial neglect after right frontal lesion.

The disorder is described as a size distortion involving the side of space. We report the case of a woman with an ipsilateral hyperschematia without neglect after a right frontal lesion. The patient has exhibited a disproportionate enlargement of the right-hand side of objects and added more left-sided petals to the drawn daisy. This pathologic behavior is independent from spatial neglect and f...

Swan Unilateral Spatial Neglect

Right unilateral spatial neglect of the left brain-damaged patients.

Right unilateral spatial neglect (USN) was investigated on three left brain-damaged patients suffering from the right homonymous hemianopsia and hemiplegia. A test battery consisted of visuo-constructive praxis; 1) putting blocks into a box, 2) bisecting a horizontal line, 3) figure drawing, 4) drawing of a dial plate and 5) copying drawing. The investigation revealed that USN of left brain-dam...
