Lack of repercussions of sleep apnea syndrome on recovery and attention disorders at the subacute stage after stroke: a study of 45 patients.

INTRODUCTION: Sleep apnea syndrome (SAS) frequently occurs after a stroke. Its association with a poor prognosis is open to discussion. OBJECTIVE: To study, in a physical and rehabilitation medicine (PRM) unit, the possible repercussions of SAS on neurological and functional recovery as well as attentional abilities following a stroke. PATIENTS AND METHODS: Forty-five patients, all of whom had recently had a stroke without previously documented SAS, were screened using the ApneaLink(®) system. An apnea-hypopnea index (AHI) score ≥10 was considered as indicative of SAS. The NIHSS, Fugl-Meyer (FM) and Functional Independence Measure (FIM) Scales were applied on admission and at two months as means of assessing neurological and functional recovery, which was expressed by the difference between the first and the second scores (delta FM, delta NIHSS, delta FIM). The Battery Attention William Lennox (BAWL) Test was given once in order to evaluate attention disorders. SAS severity was categorized according to the AHI. We compared the groups formed (mild, moderate and severe) using the same method. RESULTS: Twenty-eight patients (62.2%) presented AHI ≥ 10. Stroke characteristics were comparable in the SAS+ and the SAS- groups, with average post-stroke time lapse of 26 days, initial average FIM score of 71.2 points ± 26.3 and initial average NIHSS score of 8.9 ± 4.9. The demographic characteristics of the two groups were likewise comparable with the exception of age, as the SAS+ group was pronouncedly older (65.4 vs. 53.5 years). As for delta FIM, which evaluated functional recovery, it averaged 31.8 ± 20.6. Cases of SAS were found to be mild (37.1%), moderate (28.6%) or severe (34.3%). No significant difference was observed on admission or at 2 months as regards the clinical scales or the BAWL test between the two groups or according to severity, except for the NIHSS score at 2 months in the severe sub-group. DISCUSSION AND CONCLUSION: This study did not demonstrate the supposed repercussions of SAS on the recovery or attentional abilities of post-stroke patients. The tests were maybe given too early; they should take place at a lengthier time interval after the stroke, and also to be more complete.

Do patients have any special medical or rehabilitation difficulties after a craniectomy for malignant cerebral infarction during their hospitalization in a physical medicine and rehabilitation department?

OBJECTIVES: To observe whether medical complications, the evolution of neurological disorders and dependence and/or the discharge destinations are different for patients treated by craniectomy for malignant cerebral infarction in the middle cerebral artery compared to patients treated medically for severe or malignant cerebral infarction in the same cerebral territory, during their hospitalization in a physical medicine and rehabilitation department. PATIENTS AND METHODS: This retrospective study compared patients treated by craniectomy for malignant cerebral infarction in the middle cerebral artery and patients treated medically for severe or malignant cerebral infarction in the same cerebral territory. Patients were paired according to age, lesion side and hospitalization period. RESULTS: Twelve patients treated by craniectomy (age 43+/-10.44) were paired with 12 patients treated medically (age 49+/-7.66). The two groups were comparable in terms of general undesirable medical events. The medical events related to craniectomy are described. The evolution of patient deficiencies, the length of the hospital stay (194+/-118.93 days vs 152+/-94.64 days), the Functional Independence Measure at discharge (87+/-21.28 vs 95+/-22.19) and the number of direct home discharges (7 vs 9) did not significantly differ between groups. DISCUSSION AND CONCLUSION: No more medical problems were observed in the patients treated by craniectomy than in the patients treated medically, except for the medical events specifically related to craniectomy, which extended the hospital stay but had no major repercussions.
