Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-55 with a diagnosis of schizophrenia, schizoaffective disorder, or bipolar disorder type I who are stable in their outpatient treatment.

Probably not a fit

Patients with a recent history of substance use disorder or those with certain neurological conditions may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to investigate the effects of transcranial magnetic stimulation (TMS) on cognitive performance in individuals with psychotic disorders such as schizophrenia, schizoaffective disorder, and bipolar disorder. Participants will perform cognitive tasks and undergo brain scans before and after receiving different forms of TMS to assess changes in processing speed and brain activity. The study seeks to determine if cognitive impairments in these disorders can be modified non-invasively, providing insights into potential new interventions for improving quality of life. TMS is already FDA-approved for other psychiatric conditions, making this approach a promising avenue for treatment.

Why it matters

Potential benefit: If successful, this study could lead to new non-invasive treatments that improve cognitive function in patients with psychotic disorders.

How similar studies have gone: While TMS has been successfully used for other psychiatric disorders, this specific application for cognitive enhancement in psychosis is relatively novel and has not been extensively tested.

  * History of fainting spells of unknown or undetermined etiology that might constitute seizures
  * History of multiple seizures or diagnosis of epilepsy
  * Any progressive (e.g., neurodegenerative) neurological disorder such as multiple sclerosis or Parkinson's disease
