More frequent nightmares may precede some autoimmune diseases

An increased frequency of nightmares and hallucinations may precede the onset of certain autoimmune diseases such as lupus, says a study published in the journal eClinicalMedicine. The team surveyed 676 people with lupus and 400 physicians, as well as in-depth interviews with a smaller group. Of the patients who experienced hallucinations, 61% of those with lupus and 34% of those with other rheumatic autoimmune diseases reported having more disturbing nightmares before the hallucinations. Paying more attention to these neuropsychiatric symptoms could provide an ‘early warning system’ for earlier clinical intervention, say the authors.

Reaction: study in mice associates punctuated sleep deprivation with antidepressant mechanisms

Researchers at Northwestern University in the United States have studied the effect of a temporary decrease in sleep on the mood of mice. According to their results, the animals became more hyperactive and hypersexual for a few hours. In addition, the occasional lack of sleep had an antidepressant effect that lasted for a few days and is explained by an increase in the release of dopamine. The results are published in the journal Neuron.
