[Long-term cognitive and functional status in survivors of an aneurysmal subarachnoid hemorrhage: Analysis of a retrospective cohort].

OBJECTIVE

Little data is available on long-term functional and cognitive outcomes in patients with aneurysmal subarachnoid hemorrhage (ASH). The main objective of this study was to assess cognition, functional state, mood disorders, and quality of life in patients with SAH at least six months following the ASH.

PATIENTS AND METHODS

Cross-sectional study of 40 patients (aged 58.2 [SD 9.9] years) with ASH, discharged from a Neurologic Rehabilitation unit between January 2010 and July 2017.

MAIN OUTCOME VARIABLES

functional status (Barthel index), cognition (Pfeiffer questionnaire), depression (Hamilton scale), and health-related quality of life (European Quality of Life-5 Dimensions [EQ-5D]), as well as type and duration of therapeutic rehabilitation procedures after discharge.

RESULTS

From 35 patients with cognitive disorders, only 12 received cognitive therapy at hospital discharge. In the long-term follow-up, cognitive impairment persisted in 22 patients. When compared with those without cognitive impairment, they presented significantly worse mean differences in the Barthel index (15.5 [95% CI: 1.2-29.7]), Hamilton scale (-0.8 [95% CI: -1.27 to -0.37]), and EQ-5D (27.6 [95% CI: 12.4-19]).

CONCLUSION

The prevalence of long-term cognitive impairments in survivors of a SAH episode is high, and their presence is associated with worse functional status, more depression and worse quality of life. The low percentage of subjects who received cognitive therapies through their recovery process and the clinical implications observed, support the need of including neuropsychological therapies in the rehabilitation programs after an SAH event.
