A right-handed 37-year-old woman presented with right hemiparesis predominantly affecting the lower limb. MRI revealed the left anterior cerebral artery territory infarction (Picture 1). After complete recovery from the hemiparesis, she noticed that she would forget where her right arm was after drawing a curtain and when she moved away from the bed she had left her right leg on it. She habitually laid her right arm on her chest. Line cancellation, flower drawing, and line bisection tests were

There was no parkinsonism. Motor neglect is an underutilization of one side and presents lack of spontaneous "placing reaction", insufficient reaction to assume cor-rect posture, lack of automatic withdrawal reaction to painful stimulation, and hypometria. Her micrographia could have resulted from hypometria in line drawing. The authors state that they have no Conflict of Interest (COI). References 1. Laplane D, Degos JD. Motor neglect.
