- The relative importance of motor, perceptual, and some cognitive functions for self-care ability was analyzed in a representative sample of 109 subjects within 2 weeks of acute stroke. Forty-nine patients (45%) were dependent or partly dependent in self-care. Profound motor dysfunction was present in 39%, low-order perceptual deficits in 10%, high-order perceptual deficits in 60%, and disorientation in time and space in 13% of the patients. There was a significant covariation between motor function and self-care ability and between low-order perception and orientation function. Low-order and high-order perception covaried only weakly. Discriminant analyses showed that the actual level of self-care proficiency could be correctly predicted in 70% of the cases by the 4 indexes of motor function, low-order perception, high-order perception, and orientation. The dominating predictor was motor function, and the next highest was high-order perception. When a program for early training is designed with the aim to alleviate long-term self-care disability after stroke, correct assessment of motor and perceptual functions in the individual stroke patient is essential.

- Using the dexamethasone suppression test, we studied the activity of the hypothalamicpituitary-adrenal axis within the first week after onset in 62 patients with acute ischemic stroke. Compared with two control groups (one comprising 25 elderly patients with various acute medical disorders and the other comprising 33 80-year-old volunteers), stroke patients had higher postdexamethasone cortisol levels (p=0.08 and /?=0.001, respectively). By multiple regression analysis, high postdexamethasone cortisol levels in the stroke patients were significantly associated with proximity of the lesion to the frontal pole of the brain (p=0.008) and with disorientation (p=0.03), whereas no association with major depression was seen. Many stroke patients are exposed to hypercortisolism, which may have negative consequences upon organ functions. The extent to which dexamethasone administration suppresses cortisol levels seems to be determined mainly by the site of brain lesion and cannot be used as an indicator of major depression early after stroke.
