Journal ArticleDOI

Glutamatergic dysfunction in OCD.

TL;DR: This study provides preliminary evidence implicating glutamatergic excess in the pathophysiology of OCD, which needs to be further explored by studies from other centers involving larger sample sets from different age groups.
Journal ArticleDOI

Risperidone in the treatment of acute mania: double-blind, placebo-controlled study.

TL;DR: In patients with severe manic symptoms, risperidone produced significant improvements in YMRS scores as early as week 1 and substantial changes at end-point and treatment was well tolerated.
Journal ArticleDOI

Acute and continuation risperidone monotherapy in bipolar mania: a 3-week placebo-controlled trial followed by a 9-week double-blind trial of risperidone and haloperidol

TL;DR: It is concluded that risperidone monotherapy was an effective and well-tolerated treatment for bipolar mania and that efficacy was maintained over the long term.
Journal ArticleDOI

Anti-brain autoantibodies and altered excitatory neurotransmitters in obsessive-compulsive disorder.

TL;DR: Preliminary evidence that autoantibodies against BG and thalamus may cause OCD by modulating excitatory neurotransmission is provided, and CSF glutamate and glycine levels were significantly higher in OCD patients compared with controls, and multivariate analysis of variance showed that CSF glycine Levels were higher in those OCD patients who had autoantibia compared with those without.
Journal ArticleDOI

CSF amine metabolites in depression

TL;DR: The amine metabolites, namely homovanillic acid (HVA) and 5-hydroxy indoleacetic acid (5-HIAA) were measured in cerebrospinal fluid (CSF) of depressives and controls and correlated positively with monoamine oxidase activity and adenosine deaminase activity.
