Sleep Disorder

Background: Sleep disturbances may increase risks of Alzheimer's disease (AD) and other dementias. Benign prostatic hyperplasia (BPH) is usually associated with lower urinary tract symptoms, including nocturia, and thereby disturbed sleep. We examined if men with BPH are at increased risk of AD and all-cause dementia. Methods: In a Danish nationwide cohort (1996–2016), we identified 297,026 men with BPH, defined by inpatient or outpatient hospital diagnosis or by BPH-related surgical or medical treatment, and 1,107,176 men from the general population matched by birth year.
Neuropathic pain (NeuP) arises due to injury of the somatosensory nervous system and is both common and disabling, rendering an urgent need for non-addictive, effective new therapies. Given the high evolutionary conservation of pain, investigative approaches from Drosophila mutagenesis to human Mendelian genetics have aided our understanding of the maladaptive plasticity underlying NeuP. Successes include the identification of ion channel variants causing hyper-excitability and the importance of neuro-immune signaling.
