“…Indeed, the evidence suggests that eliminating water from the body will constrain brain functions and decrease cognitive performance, and that there is no positive or direct relationship between enriched learning and water consumption (Rato et al, ). Excessive liquid consumption may even be harmful, leading in some cases to hyponatremia or water poisoning (e.g., Boetzkes et al, ; Miyamoto et al, ).…”

Understanding preservice teachers' misconceptions regarding the brain and neuroscience (neuromyths) can provide information that helps teachers to apply neuroscience knowledge in an educational context. The objective of this study was to investigate these misconceptions. Following preliminary research, a questionnaire comprising 59 challenging assertions in two categories (education and neuromyths) was developed as a data collection tool. The findings identify preservice teachers' neuromyths, which were found to vary by teaching area.

“…A case of water intoxication secondary to administration of hypotonic fluids in oral rehydration in an infant with gastroenteritis was reported 7. Some cases of water intoxication in children treated with desmopressin due to nocturnal enuresis, with or without concomitant drugs as an anticholinergic were also described 8…”

The authors report a case of a 15-year-old girl with hypopituitarism due to pituitary stalk interruption syndrome diagnosed in the neonatal period. The patient was admitted to the emergency room with impaired consciousness and hypoglycaemia. The day before, she increased her water intake to about 1.5 L to perform a pelvic ultrasound. In the following hours, she developed vomiting and food refusal. Blood analysis revealed hypoglycaemia, hyponatraemia, decreased serum osmolality and normal urinary density. Hyponatraemia and adrenal crisis were managed with a gradual but slow resolution of consciousness and electrolytic balance. This case describes an episode of iatrogenic water intoxication in a patient under desmopressin treatment. Although uncommon, dilutional hyponatraemia is the main complication of desmopressin treatment. We reinforce the importance of patients and caregivers' long-life education for the potential complications of an increase in fluid intake in patients treated with desmopressin.
