Distressing dreams in childhood and risk of cognitive impairment or Parkinson's disease in adulthood: a national birth cohort study.

Background: Distressing dreams in middle-aged and older adults have been associated with an increased risk of developing cognitive impairment (including dementia) and Parkinson's disease (PD). Whether distressing dreams in younger people might be associated with an increased risk of developing these conditions is unknown. This study investigated the association between distressing dreams in childhood and the risk of developing cognitive impairment or PD by age 50.

Distressing dreams, cognitive decline, and risk of dementia: A prospective study of three population-based cohorts.

Background: Distressing dreams are associated with faster cognitive decline and increased dementia risk in people with Parkinson's disease (PD). Whether distressing dreams might be associated with cognitive decline and dementia in people without PD is unknown. This study investigated the association between self-reported distressing dream frequency and the risk of cognitive decline and incident dementia in community-dwelling men and women without cognitive impairment or PD.

Association of sleep abnormalities in older adults with risk of developing Parkinson's disease.

Study Objectives: Parkinson's disease (PD) is associated with abnormalities of sleep macro- and microstructure as measured using polysomnography (PSG). Whether these abnormalities precede the development of PD is unknown. This study investigated the association between PSG measured sleep abnormalities in older adults and the risk of incident PD.

Religiosity and Risk of Parkinson's Disease in England and the USA.

Parkinson's disease (PD) is associated with low religiosity cross-sectionally. Whether low religiosity might be associated with an increased risk for developing PD is unknown. This study investigated whether low religiosity in adulthood is associated with increased risk for developing PD.

Dream Content Predicts Motor and Cognitive Decline in Parkinson's Disease.

Background: Dream content alterations in Parkinson's disease (PD) are associated with motor and cognitive dysfunction cross-sectionally. Although recent studies suggest abnormal dream content in PD might also predict cognitive decline, the relationship between dream content and motor decline in PD remains unknown.

Objective: To investigate whether abnormal dream content in PD predicts both motor and cognitive decline.

Adherence to wakefulness promoting medication in patients with narcolepsy.

Objective: Narcolepsy management usually requires lifelong pharmacotherapy. However, we know little about adherence to prescribed treatment in narcolepsy. We assessed adherence to wakefulness-promoting agents in narcolepsy patients.

Awakening Ptosis: A Clinical Review.

A rare condition characterized by a transient inability to open one or both eyes upon awakening from sleep was first described in 1897. Although less than a handful of papers have been written about this condition since its initial description, a well-defined clinical entity emerges from the available literature. This article reviews the history and clinical features of this unusual condition.

Did René Descartes Have Exploding Head Syndrome?

René Descartes (1596-1650), "the Father of Modern Philosophy" and advocate of mind-body dualism, had three successive dreams on November 10, 1619 that changed the trajectory of his life and the trajectory of human thought. Descartes' influential dreams have been of interest to a number of commentators including the famous neurologist and psychoanalyst Sigmund Freud. Descartes' second dream in particular, in which he heard a loud noise in his head before seeing a bright flash of light upon awakening, has been discussed extensively.
