Dehydration Influences Mood and Cognition: A Plausible Hypothesis?

Dehydration Influences Mood and Cognition: A Plausible Hypothesis?

The hypothesis was considered that a low fluid intake disrupts cognition and mood. Most research has been carried out on young fit adults, who typically have exercised, often in heat. The results of these studies are inconsistent, preventing any conclusion. Even if the findings had been consistent, confounding variables such as fatigue and increased temperature make it unwise to extrapolate the...

Dehydration and Cognition in Geriatrics: A Hydromolecular Hypothesis

Dehydration is one of the ten most frequent diagnoses responsible for the hospital admission of elderly in the United States. It is associated with increased mortality, morbidity and an estimated cost of 1.14 billion per year (Xiao et al., 2004; Schlanger et al., 2010; Pretorius et al., 2013; Frangeskou et al., 2015). Older individuals are predisposed to dehydration encephalopathy as a result o...

Affective Influences on Cognition Mood Congruence, Mood Dependence, and Mood Effects on Processing Strategies

The interplay between feeling and thinking has been a subject of scholarly discussion and spirited debate since antiquity. The last few decades have witnessed a mounting interest in the impact of affective or mood states on learning, memory, decision making, and allied cognitive processes. Much of this interest has initially focused on two phenomena: mood-congruent cognition —the observation th...

Dioxins and endometriosis: a plausible hypothesis.

A potential connection exists between exposure to organochlorine chemicals and the increasing prevalence of endometriosis. Evidence shows that dioxin (2,3,7,8-tetrachlorodibenzo-p-dioxin) can increase the incidence and severity of the disease in monkeys and can promote the growth or survival of endometrial tissue implanted into rodents in a surgically induced model of endometriosis. The mechani...
