Focusing in COVID-19 patients, is known that SARS-CoV-2 infection affects both the peripheral and the central nervous systems and is associated with a broad spectrum of neurological syndromes. Although rates of psychiatric morbidity associated with COVID-19-related brain dysfunction remain unknown, early reports suggest that non-critical SARS-CoV-2 patients suffer from attention deficits, processing speed difficulties and anomia after overcoming the disease

Acute obesogenic diet administration in mice impaired recognition memory due to defective production of the neurosteroid precursor pregnenolone in the hypothalamus. Genetic interference with pregnenolone synthesis by Star deletion in hypothalamic POMC, but not AgRP neurons, deteriorated recognition memory independently of metabolic disturbances.

Juvenile fibromyalgia (JFM) is a prevalent chronic pain condition affecting children and adolescents worldwide during a critical period of brain development. To date, no published studies have addressed the pathophysiology of JFM. Here we characterize gray matter volume (GMV) alterations in JFM patients for the first time and investigate their functional and clinical relevance

Brain atrophy and cognitive impairment in neurodegenerative diseases are influenced by sex. We aimed to investigate sex differences in brain atrophy and cognition in de novo Parkinson's disease (PD) patients

The aim of this study was to evaluate the differences in clinical presentation according to the use of cannabis (cannabis users vs non-users) among patients presenting a FEP (non-affective vs affective psychosis), to investigate the impact of CR and cannabis use on several outcomes and to explore the potentially mediatory role played by CR in the relationship between cognitive domains or clinical status and functionality, depending on the use of cannabis.
