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.

Diffusion tensor MR imaging of white matter integrity in HIV-positive patients with planning deficit.

Introduction: The aim of this study was to evaluate whether normal controls and human immunodeficiency virus (HIV) patients with and without planning deficits differ on white matter integrity.

Methods: A total of 34 HIV-positive patients with planning deficits were compared with 13 HIV-positive patients without planning deficits and 19 gender-, age-, and education-matched control subjects. Diffusion tensor imaging (DTI) was performed along 30 noncolinear directions in a 1.
