In the January issue of Brain A journal of Neurology, Dr. Hans-Otto Karnath and his team at University of Tübingen Germany investigate The anatomy underlying acute versus chronic spatial neglect: a longitudinal study
Acute brain imaging (acquired on average 6.2 days post-injury) was used to evaluate neglect symptoms at the initial (mean 12.4 days post-stroke) and the chronic (mean 491 days) phase of the stroke. Chronic neglect was found in about one-third of the patients with acute neglect.
The team’s findings infer that individuals who experience spatial neglect in the initial phase of the stroke yet do not have injury to cortical including the superior and middle temporal gyri and sub-cortical including basal ganglia and inferior occipitofrontal fasciculus/extreme are likely to recover, and thus have a favorable prognosis.

The HandTutor system has virtual tasks that purposely draw the patient’s attention to the right and left side of the screen during exercise practice. This gives the patient augmented feedback and stimulation in these areas of the screen.
