SYNGAP-1 Mutation And Catatonia: A Case Series and Systematic Review.

Hyperactive catatonia is often unrecognized in pediatric patients due to its clinical heterogeneity, though it is often seen in children with neurodevelopmental disabilities, especially autism spectrum disorder (ASD). Emerging evidence implicates hyperactive catatonia in more cases of self-injury and aggression in ASD than previously thought. The study seeks to describe cases of hyperactive catatonia in SYNGAP-1 mutation and examine existing literature for symptomatic overlap between previously-described clinical and behavioral phenotypes of individuals with SYNGAP-1 mutations and catatonia.

Preliminary comparative study of cortical thickness in HIV-infected patients with and without working memory deficit.

Purpose: Changes in cerebral cortical regions occur in HIV-infected patients, even in those with mild neurocognitive disorders. Working memory / attention is one of the most affected cognitive domain in these patients, worsening their quality of life. Our objective was to assess whether cortical thickness differs between HIV-infected patients with and without working memory deficit.

Persistence of the craniopharyngeal canal.

Craniopharyngeal canal persistence is a congenital abnormality characterized by a bone canal extending from the nasopharynx to the pituitary fossa. Ascension of microorganisms through the channel can occur, triggering meningitis.
