Psychiatry lacks the objective clinical tests routinely used in other specializations. Novel computerized methods to characterize complex behaviors such as speech could be identify and predict psychiatric illness individuals.In this proof-of-principle study, our aim was test automated analyses combined with Machine Learning later psychosis onset youths at high-risk (CHR) for psychosis.Thirty-four CHR (11 females) had baseline interviews were assessed quarterly up 2.5 years; five transitioned...
Background Psychosis has various causes, including mania and schizophrenia. Since the differential diagnosis of psychosis is exclusively based on subjective assessments oral interviews with patients, an objective quantification speech disturbances that characterize schizophrenia in order. In principle, such could be achieved by analysis graphs. A graph represents a network nodes connected edges; graphs, correspond to words edges semantic grammatical relationships. Methodology/Principal...
In chronic psychotic patients, word graph analysis shows potential as complementary psychiatric assessment. This relies mostly on connectedness, a structural feature of speech that is anti-correlated with negative symptoms. Here we aimed to verify whether disorganization during the first clinical contact, measured by can correctly classify symptoms and schizophrenia diagnosis 6 months in advance. Positive syndrome scale scores memory reports were collected from 21 patients undergoing contact...
Early psychiatry investigated dreams to understand psychopathologies. Contemporary psychiatry, which neglects dreams, has been criticized for lack of objectivity. In search quantitative insight into the structure psychotic speech, we speech graph attributes (SGA) in patients with schizophrenia, bipolar disorder type I, and non-psychotic controls as they reported waking dream contents. Schizophrenic subjects spoke reduced connectivity, tight correlation negative cognitive symptoms measured by...
Semantic verbal fluency test is an important cognitive measure, broadly used in the neuropsychological assessment of elderly, however its standards scores are less informative than what this task can provide. Graph theory represents a promising tool to understand variety states and study presents graph analysis data generated by semantic health elderly (NC), patients with Mild Cognitive Impairment – subtypes amnestic (aMCI) multiple domain (a+mdMCI) - Alzheimer's disease (AD). The groups...
The current global threat brought on by the Covid-19 pandemic has led to widespread social isolation, posing new challenges in dealing with metal suffering related distancing, and quickly learning habits intended prevent contagion. Neuroscience psychology agree that dreaming helps people cope negative emotions learn from experience, but can effectively reveal mental changes behavior? To address this question, we applied natural language processing tools study 239 dream reports 67...
Abstract This workshop summary on natural language processing (NLP) markers for psychosis and other psychiatric disorders presents some of the clinical research issues that NLP might address activities needed to move in direction. We propose optimal development would occur context efforts map out underlying mechanisms disorders. In this workshop, we identified challenges be addressed developing implementing markers-based Clinical Decision Support Systems (CDSSs) practice, especially with...
Abstract Background Language anomalies are a hallmark feature of schizophrenia-spectrum disorders (SSD). Here, we used network analysis to examine possible differences in syntactic relations between patients with SSD and healthy controls. Moreover, assessed their relationship sociodemographic factors, psychotic symptoms, cognitive functioning, evaluated whether the quantification measures has diagnostic value. Study Design Using semi-structured interview, collected speech samples from 63 Per...
Selecting an appropriate book is crucial for fostering reading habits in children. While children exhibit varying levels of complexity when generating oral narratives, the question arises: do children's books also differ narrative complexity? This study explores dynamics literary texts used schools, focusing on how their evolves across different grade levels. Using Word-Recurrence Graph Analysis, we examined a dataset 1,627 spanning 13 years education. The findings reveal significant...
ABSTRACT To explore the relationship between memory and early school performance, we used graph theory to investigate reports from 76 children aged 6–8 years. The comprised autobiographical memories of events days years past, novel images reported immediately after encoding. We also measured intelligence quotient ( IQ ) mind ToM ). Reading Mathematics were assessed before classes began (December 2013), around time report collection (June 2014), at end academic year 2014). correlated...
Discourse varies widely with age, level of education, and psychiatric state. Word graphs have been recently shown to provide behavioral markers formal thought disorders in psychosis (e.g., disorganized flow ideas) track literacy acquisition children typical development. Here we report that a graph-theoretical computational analysis verbal reports from subjects spanning 6 decades age 2 education reveals asymptotic changes over time depend more on than age. In subjects, short-range recurrence...
Dreaming and psychosis share important features, such as intrinsic senseperceptions independent of external stimulation, a general lack criticism that is associated with reduced frontal cerebral activity. Awareness dreaming while dream happening defines lucid (LD), state in which the prefrontal cortex more active than during regular dreaming. For this reason, LD has been proposed to be potentially therapeutic for psychotic patients. According view, patients would expected report less...
Dream reports collected after rapid eye movement sleep (REM) awakenings are, on average, longer, more vivid, bizarre, emotional and story-like compared to those non-REM. However, a comparison of the word-to-word structural organization dream is lacking, traditional measures that distinguish REM non-REM dreaming may be confounded by report length. This problem amenable analysis as non-semantic directed word graphs, which provide assessment oral reports, while controlling for individual...
Mirror invariance is a visual mechanism that enables prompt recognition of mirror images. This capacity emerges early in human development, useful to recognize objects, faces, and places from both left right perspectives, also present primates, pigeons, cephalopods. Notwithstanding, the same has been suspected be source specific difficulty for relatively recent invention—reading—by creating confusion between letters (e.g., b-d Latin alphabet). Using an ecologically valid school-based design,...
Laboratory evidence of a positive effect sleep on declarative memory consolidation suggests that naps can be used to boost school learning in scalable, low-cost manner. The few direct investigations this hypothesis have so far upheld it, but departed from the naturalistic setting by testing non-curricular contents presented experimenters instead teachers. Furthermore, nap and non-nap groups were composed different children. Here we assessed post-class retention Science History curricular...
