Research Abstract
My research is focused on sleep, sleep disorders (especially sleep related breathing disorders and movement disorders), psychotropic drugs effect on sleep and wakefulness, sleep disorders affecting cardiovascular diseases and neuromuscular diseases. Below are the examples of research projects I have carried out and/or ongoing:
- Sleep related breathing disorders (SRBD) in medical ICU patients
- Sleep position preference in patients with untreated OSA versus non-OSA patients
- Prominent positional OSA in patients with stroke
- Periodic limb movement (PLM) in patients with leg paresis/plegia
- Role of serotonin in profound hypoxemia/hypoventilation
- PLM in patients taking serotonergic agents
- SRBD pattern in patients with neuromuscular disease
- Severe sleepiness in patients with myotonic dystrophy
- OSA in wake-up stroke
- Efficacy comparison of various sleep aids
- Effects of sleep aids on OSA
- Central sleep apnea pattern in acute stroke
- Patient characteristics in augmentation of restless legs syndrome (RLS)
- Effect of sleep intervention on neurocognitive outcomes of Alzheimer Disease patients
