Background: Although the chance of surviving an aneurysmal subarachnoid haemorrhage (aSAH) has increased steadily, disturbed sleep and persistent psychological complaints are frequently experienced post-ictus. To date, however, few studies have sought to determine whether physiological parameters, such as objectively measured sleep and cortisol secretion, interrelate significantly with low sleep quality and psychological complaints such as depression. Furthermore, there is little evidence as to whether post-ictal complaints differ between aSAH patients and other groups who have experienced stressful medical intervention.
Methods: Data on objective and subjective sleep, sleep-related dysfunctional cognitions, psychological functioning and cortisol secretion were collected from 15 patients who had undergone medical intervention for aSAH. Data were also collected from a group of 16 individuals who had undergone surgery for a meningioma and a third group made up of 17 healthy participants.
Results: aSAH patients and meningioma patients had significantly poorer subjective sleep than healthy controls and reported more sleep-related dysfunctional cognitions and hypochondriacal beliefs. They also had a significantly higher morning cortisol response. Finally, a non-significant trend was found showing that aSAH patients and meningioma patients reported poorer psychological functioning than healthy controls.
Conclusion: Following treatment, aSAH patients and meningioma patients experience poorer subjective sleep and some differences in objectively measured sleep, which might be attributable to increased sleep-related dysfunctional cognitions and poorer overall psychological functioning. Differences in cortisol production were also observed, suggesting that some physiological imbalances are still present post-ictus.
