Staging systems in bipolar disorder: an International Society for Bipolar Disorders Task Force Report
2014
Objective: We discuss the rationale behind staging systems described specifically for bipolar disorders. Current applications, future directions and research gaps in clinical staging models for bipolar disorders are outlined. Method: We reviewed the literature pertaining to bipolar disorders, focusing on the first episode onwards. We systematically searched data on staging models for bipolar disorders and allied studies that could inform the concept of staging. Results: We report on several dimensions that are relevant to staging concepts in bipolar disorder. We consider whether staging offers a refinement to current diagnoses by reviewing clinical studies of treatment and functioning and t…
Education and long-term outcomes in first episode psychosis: 10-year follow-up study of the PAFIP cohort
2021
[Background] Lower levels of education have been associated with the development of psychosis. Investigating educational achievement in the first episode of psychosis (FEP) patients may shed light on the origins of the alterations and on the variability of outcomes in psychotic disorders.
The challenge of forgetting: Neurobiological mechanisms of auditory directed forgetting
2017
Directed forgetting (DF) is considered an adaptive mechanism to cope with unwanted memories. Understanding it is crucial to develop treatments for disorders in which thought control is an issue. With an item-method DF paradigm in an auditory form, the underlying neurocognitive processes that support auditory DF were investigated. Subjects were asked to perform multi-modal encoding of word-stimuli before knowing whether to remember or forget each word. Using functional magnetic resonance imaging, we found that DF is subserved by a right frontal-parietal-cingulate network. Both qualitative and quantitative analyses of the activation of this network show converging evidence suggesting that DF …
Rhetoric, Neurocognitive Poetics, and the Aesthetics of Adaptation
2017
Rhetorical effects in speech and writing have a great strategic importance in achieving the communicative end of being persuasive: they are key in the exertion of power through language. Persuasion occurs by cognitive-affective stimulation, relying on specific psychosomatic perceptual patterns which are used on all levels of speech reception in cultural and political contexts. This makes rhetorically conspicuous texts efficient as stimulus material for empirical research into neurocognitive modeling of how poetic texts are read. Adaptations as revisitations of prior works share with the rhetorical repertoire of repetition similar cognitive-affective properties, because both function via rec…
Is processing speed a valid neurocognitive endophenotype in bipolar disorder? Evidence from a longitudinal, family study.
2021
[Background] Substantial evidence supports the existence of neurocognitive endophenotypes in bipolar disorder (BD), but very few longitudinal studies have included unaffected relatives. In a 5-year, follow-up, family study, we have recently suggested that deficits in manual motor speed and visual memory could be endophenotype candidates for BD. We aimed to explore whether this also applies to processing speed.
Transdiagnostic neurocognitive deficits in patients with type 2 diabetes mellitus, major depressive disorder, bipolar disorder, and schizophrenia: A …
2021
AbstractBackgroundImpairments in neurocognition are critical factors in patients with major depressive disorder (MDD), bipolar disorder (BD), and schizophrenia (SZ), and also in those with somatic diseases such as type 2 diabetes mellitus (T2DM). Intriguingly, these severe mental illnesses are associated with an increased co-occurrence of diabetes (direct comorbidity). This study sought to investigate the neurocognition and social functioning across T2DM, MDD, BD, and SZ using a transdiagnostic and longitudinal approach.MethodsA total of 165 subjects, including 30 with SZ, 42 with BD, 35 with MDD, 30 with T2DM, and 28 healthy controls (HC), were assessed twice at a 1-year interval using a c…
Infant brain responses associated with reading-related skills before school and at school age
2011
Summary Introduction In Jyvaskyla Longitudinal Study of Dyslexia, we have investigated neurocognitive processes related to phonology and other risk factors of later reading problems. Here we review studies in which we have investigated whether dyslexic children with familial risk background would show atypical auditory/speech processing at birth, at six months and later before school and at school age as measured by brain event-related potentials (ERPs), and how infant ERPs are related to later pre-reading cognitive skills and literacy outcome. Patients and methods One half of the children came from families with at least one dyslexic parent (the at-risk group), while the other half belonge…
Metabolic, Affective and Neurocognitive Characterization of Metabolic Syndrome Patients with and without Food Addiction. Implications for Weight Prog…
2021
According to the food addiction (FA) model, the consumption of certain types of food could be potentially addictive and can lead to changes in intake regulation. We aimed to describe metabolic parameters, dietary characteristics, and affective and neurocognitive vulnerabilities of individuals with and without FA, and to explore its influences on weight loss progression. The sample included 448 adults (55-75 years) with overweight/obesity and metabolic syndrome from the PREDIMED-Plus cognition sub-study. Cognitive and psychopathological assessments, as well as dietary, biochemical, and metabolic measurements, were assessed at baseline. Weight progression was evaluated after a 3-year follow u…
The effect of hypoglycaemia on neurocognitive outcome in children and adolescents with transient or persistent congenital hyperinsulinism.
2018
To examine the hypoglycaemic effect on neurodevelopmental outcome in patients with transient and persistent congenital hyperinsulinism (CHI) born in the 21A cohort of 117 patients (66 males, 51 females) with CHI aged 5 to 16 years (mean age 8y 11mo, SD 2y 7mo) were selected from a Finnish nationwide registry to examine all the patients with similar methods. Neurodevelopment was first evaluated retrospectively. The 83 patients with no risk factors for neurological impairment other than hypoglycaemia were recruited and 44 participated (24 males, 20 females; mean age 9y 7mo, SD 3y 1mo) in neuropsychological assessment with the Wechsler Intelligence Scale for Children, Fourth Edition and the Fi…
Redefining the MED13L syndrome
2015
Congenital cardiac and neurodevelopmental deficits have been recently linked to the mediator complex subunit 13-like protein MED13L, a subunit of the CDK8-associated mediator complex that functions in transcriptional regulation through DNA-binding transcription factors and RNA polymerase II. Heterozygous MED13L variants cause transposition of the great arteries and intellectual disability (ID). Here, we report eight patients with predominantly novel MED13L variants who lack such complex congenital heart malformations. Rather, they depict a syndromic form of ID characterized by facial dysmorphism, ID, speech impairment, motor developmental delay with muscular hypotonia and behavioral difficu…
