“…Previous data suggests that these patients may show a higher frequency of certain symptoms such as agitation, myoclonus, abulia, and alogia. Some distinct neuroinflammatory syndromes have been identified in patients presenting with delirium associated with the virus, namely, autoimmune encephalitis, Acute Disseminated Encephalomyelitis (ADEM) and stroke showing its potential for CNS involvement. …”

“…Our study focused on the impact of cognitive deficit and severity of negative symptoms (i.e., the experiential domain (avolition, asociality, and anhedonia) and the expressive domain (blunted affect and alogia)) to explore psychosocial functioning in schizophrenia. …”

“…Either BNSS Motivation and Pleasure (MAP) and Emotional Expressivity (EE) or BNSS five-factor (Anhedonia, Asociality, Avolition, Blunted Affect, Alogia) were examined with PANSS factors and demographics in logistic regression with employment status and working full-time as outcome variables. …”

“…Increasing evidence supports the superiority of a five-factor model (alogia, blunted affect, anhedonia, avolition, and asociality as defined by the NMIH-MATRICS Consensus); however, previous data primarily used the Brief Negative Symptoms Scale (BNSS). …”

“…Preliminary evidence highlighted: a correlation between social cognition and negative symptoms, in particular with the “expressive deficit” domain; a positive correlation between the severity of negative symptoms and that of neurocognitive deficits (in particular with the “processing speed” domain); an association of verbal working memory deficits with alogia and anhedonia. CONCLUSIONS: The study of the relationship between negative symptoms, neurocognitive deficits and social cognition could contribute to the understanding of the aetiology of psychotic disorders and therefore to the identification of therapies for the improvement of overall functioning and quality of life. …”

“…On admission, the patient experienced psychotic symptoms, including delusions and auditory hallucinations, in addition to negative symptoms, such as affective flattening, alogia, avolition and asociality. He was then started on 12 mg of Haloperidol and 200 mg of Chlorpromazine with a white blood cells count (WBC) of 5.98 x 10(9)/L and absolute neutrophil count (ANC) of 2.52 x 10(9)/L (WBC reference range: 4.0-10.0 x 10(9) /L; ANC reference range: 1.5-7.0 x 10(9) /L). …”

“…The participating experts/countries most frequently reported the following five negative symptoms: avolition, blunted affect, alogia, asociality, and anhedonia. Several experts also considered other symptoms as belonging to the negative symptom domain, such as a decrease in energy level and changes in personality. …”
