Exploring how a neurotransmitter affects memory problems in older adults with schizophrenia

Determining the relationship between NAAG and memory deficits in schizophrenia in mid- to late- life

NIH-funded research Johns Hopkins University · NIH-11129119

This study is looking at how a substance called NAAG might help improve memory problems in older adults with schizophrenia, and it aims to find ways to boost NAAG levels to support better brain function and memory.

What this research studies

This research investigates the role of N-acetyl-aspartyl-glutamate (NAAG) in memory deficits experienced by older adults with schizophrenia. By focusing on the relationship between NAAG levels and cognitive function, the study aims to understand how increasing NAAG through the inhibition of a specific enzyme could improve memory symptoms. The research will utilize both animal models and human data to explore the effects of NAAG modulation on brain function and memory performance. This could lead to new therapeutic strategies for enhancing cognitive abilities in this patient population.

Who could benefit from this research

Good fit: Ideal candidates for this research are older adults diagnosed with schizophrenia who are experiencing cognitive deficits.

Not a fit: Patients who are not diagnosed with schizophrenia or who are younger than 21 years old may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved memory function and quality of life for older adults suffering from schizophrenia.

How similar studies have performed: Previous research has shown promising results in animal models regarding the modulation of NAAG and its effects on memory, but human data is limited and this approach is relatively novel.
