Abstract

Orientation is an indicator of general intellectual function and is defined as the ability to report time, place, and personal data. Our knowledge of orientation in acute stroke is sparse. We examined the frequency of impaired orientation in acute stroke, its determinants, and recovery in 653 consecutive patients with acute stroke who were not unconscious and who were without severe aphasia. Prospective assessments of orientation and stroke severity were done by the Scandinavian Neurologic Stroke Scale at the time of acute admission and hereafter weekly until the end of rehabilitation. Impaired orientation was found in 23% of the patients on acute admission and in 12% of the survivors after completed rehabilitation. A stationary level of orientation was achieved by 80% of the patients within 2 weeks and by 95% within 6 weeks. A multiple linear regression analysis found neurological score (B = 0.027, SE(B) = 0.003), age (B = -0.013, SE(B) = 0.003), and comorbidity (B = -0.023, SE(B) = 0.078), but not sex, prior stroke, handedness, or side of stroke lesion to be significant independent determinants of orientation score on acute admission. Lesions involving the anterior and medial thalamus and/or any of the cerebral lobes were ass...Continue Reading

Auditory Perception

Auditory perception is the ability to receive and interpret information attained by the ears. Here is the latest research on factors and underlying mechanisms that influence auditory perception.

Aphasia

Aphasia affects the ability to process language, including formulation and comprehension of language and speech, as well as the ability to read or write. Here is the latest research on aphasia.
