The overall goal of this research is to elucidate how environmental, healthcare, and patient-level factors and patients' level of perceived control impact sleep duration and quality in hospitalized older patients and to assess whether better in-hospital sleep is associated with improved physical activity and health outcomes.
We hypothesize that environment, healthcare disruptions and patient symptoms will be significantly associated with objective and subjective sleep duration and sleep quality in hospitalized older patients.
We also hypothesize that a high level of perceived control will be associated with improved sleep duration and quality in hospitalized older patients.
We further hypothesize that shorter sleep duration and quality in hospitalized older adults will be associated with adverse health outcomes, namely higher blood pressure and blood sugar.
This research can lead to a better understanding of the effects of inpatient sleep on health outcomes for hospitalized older patients and can help inform the design and evaluation of interventions designed to improve sleep in hospitalized older patients. This work can also form the foundation for understanding the longer term health effects of inpatient sleep loss for older patients that are potentially modifiable.

To our knowledge, the influence of sleep deprivation on hearing levels has yet to be assessed in animals. Therefore, we evaluated whether auditory function was affected by sleep deprivation in rats.
To investigate the cumulative effect of 5 consecutive nights of partial sleep deprivation on a panel of cerebrospinal fluid (CSF) biomarkers in healthy adults.
REM sleep is essential for learning and memory processes, particularly emotional learning. Manipulations of REM sleep impair learning and memory and sleep architecture is often altered following a lea...
The state of being deprived of sleep under experimental conditions, due to life events, or from a wide variety of pathophysiologic causes such as medication effect, chronic illness, psychiatric illness, or sleep disorder.
Excessive periodic leg movements during sleep that cause micro-arousals and interfere with the maintenance of sleep. This condition induces a state of relative sleep deprivation which manifests as excessive daytime hypersomnolence. The movements are characterized by repetitive contractions of the tibialis anterior muscle, extension of the toe, and intermittent flexion of the hip, knee and ankle. (Adams et al., Principles of Neurology, 6th ed, p387)
A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES. (From Adams et al., Principles of Neurology, 6th ed, p395)
Periods of sleep manifested by changes in EEG activity and certain behavioral correlates; includes Stage 1: sleep onset, drowsy sleep; Stage 2: light sleep; Stages 3 and 4: delta sleep, light sleep, deep sleep, telencephalic sleep.
Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)
