Active clinical trials for "Schizophrenia"

Memantine as an add-on therapy to clozapine may improve schizophrenia negative symptoms and cognitive functioning.

We propose to establish a database characterizing the presence or absence of comorbid PTSD in veterans with schizophrenia or schizoaffective disorder (SAD) receiving services at the Durham VA Medical Center. In addition to the evaluation of PTSD symptoms in veterans with schizophrenia or SAD, this database will facilitate the investigation of a number of additional specific research questions relevant to veterans with psychotic disorders.

Flunarizine is a calcium channel blocker traditionally used for the treatment of vertigo and migraine. It also has the mechanism of action associated with antipsychotic activity (D2 receptor blockade), but has never been tested as such. The investigators hypothesis is that flunarizine can be an atypical antipsychotic.

This study will investigate adjunctive pregnenolone for patients with schizophrenia and schizoaffective disorder.

Cognitive Remediation Therapy (CRT) can enhance cognitive performance in patients with schizophrenia improving clinical outcome. However, the neurobiological mechanism underlying cognitive improvement is not well understood. The aim of this study is to investigate functional connectivity patterns before and after the neurocognitive rehabilitation therapy, especially in fronto-temporal circuitry.

This is a six week, double blind,placebo controlled study for patients with schizophrenia or schizoaffective disorder treated with an atypical antipsychotic for at least two months. Subjects will be randomized to take armodafinil (Nuvigil) or placebo along with their current antipsychotic and tested at baseline and week 6 for differences in memory, attention and problem-solving ability. Changes in weight during the six week study will also be tracked.

Huperzine is a natural plant product with procognitive properties in patients with Alzheimer's disease. Cognitive difficulties hamper functioning in schizophrenia as well. The present study will investigate whether huperzine improves cognition and functioning in patients with schizophrenia.

The purpose of this study is to compare retrospective hospitalization rates of schizophrenic patients treated with oral antipsychotics to prospective hospitalization rates of these patients treated with IM depot aripiprazole.

This study is testing the hypothesis that Entacapone added to ongoing antipsychotic treatment can be beneficial in schizophrenic patients with negative symptoms.

The study will provide an empirical basis for a pharmacological treatment option. An open-label, randomized, multi-centre parallel group design is used. An intensified clinical management (CM), which allows needs-based psychological crisis intervention, is compared to a combination of such a CM and the atypical neuroleptic amisulpride. The central hypothesis is that the combination of a clinical management with an atypical neuroleptic is the superior treatment.
