Who could benefit from this research

Could help

Ideal candidates are adults diagnosed with first-episode or chronic schizophrenia who can tolerate MRI scanning, and healthy adults may be recruited as comparison participants.

Less likely to help

People without schizophrenia or those who cannot have MRI scans (for example, due to implanted devices, severe claustrophobia, or inability to lie still) are unlikely to be eligible or benefit directly from participation.

What this research studies

You would come to McLean Hospital for brain scans that use high-field magnetic resonance spectroscopy while you do a short working memory task. The team will compare people with first-episode schizophrenia, people with chronic schizophrenia, and healthy volunteers to see how lactate and other energy markers change during the task. Researchers will link those metabolic signals to thinking performance and to medication history. The goal is to understand whether a shift toward glycolysis (higher lactate) during cognitive effort relates to the memory and thinking problems people experience.

Why it matters

Potential benefit: If successful, this could clarify energy-based causes of cognitive problems in schizophrenia and point toward new treatment approaches targeting brain metabolism.

How similar studies have gone: Prior resting-state MRS studies found higher lactate in chronic schizophrenia, but measuring dynamic lactate during cognitive tasks with functional MRS is relatively new and less tested.
