White matter correlates of impulsive behavior in healthy individuals: A diffusion magnetic resonance imaging study.

Aim: To explore white matter (WM) tracts linked to impulsivity using the diffusion magnetic resonance imaging (DMRI) connectometry method.

Methods: We analyzed 218 healthy participants from the Leipzig Study for Mind-Body-Emotion Interactions database. Impulsivity correlations with DMRI-derived WM changes were assessed using Urgency-Premeditation-Perseverance-Sensation (UPPS) Impulsive Behavior Scale subscales: lack of perseverance (PE), lack of premeditation (PM), sensation seeking (SS), and negative urgency.

Depression is associated with the nonmotor symptoms of Parkinson's disease: A comparative analysis.

Background And Aims: The nonmotor symptoms (NMS) of Parkinson's disease (PD) and their potential role in early diagnosis are recent debates. Herein, we aimed to investigate the association between depression and NMS of PD including sleep disorders, hyposexuality, hyposmia, constipation, and orthostatic hypotension.

Methods: A total of 93 PD patients with depression and 67 PD patients without depression were included in the study, and NMS were compared between the two groups.

Anti N-Methyl-D-Aspartate (NMDA) receptor encephalitis: from psychosis to cognitive impairment.

In this study, while presenting a clinical case with early psychiatric manifestations, we emphasized the need to pay attention to neurological diagnoses such as Anti N-Methyl-D-Aspartate Receptor (NMDAR) encephalitis at the time of manifestation of these common symptoms.
