Investigating the link between smell deficits and cognitive symptoms in schizophrenia

Project 2

NIH-funded research Johns Hopkins University · NIH-11072025

This study is looking at how problems with smell might affect thinking and feelings in people with schizophrenia, especially during their teenage years and early adulthood, and it involves some smell tests and activities to help us learn more about this connection.

What this research studies

This research explores how changes in the sense of smell may affect cognitive functions and negative symptoms in individuals with schizophrenia. By examining the olfactory system and its connections to brain regions involved in motivation and social cognition, the study aims to understand how olfactory deficits correlate with symptoms like anhedonia and avolition. The research will involve assessing olfactory sensory neurons and their impact on the prefrontal cortex, particularly during critical developmental periods in adolescence and young adulthood. Patients may undergo behavioral assessments and olfactory tests to contribute to this understanding.

Who could benefit from this research

Good fit: Ideal candidates for participation are individuals diagnosed with schizophrenia, particularly those experiencing negative symptoms and cognitive deficits.

Not a fit: Patients without a diagnosis of schizophrenia or those who do not exhibit olfactory deficits may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to new insights into treating cognitive and negative symptoms in schizophrenia, potentially improving quality of life for patients.

How similar studies have performed: Previous research has indicated a correlation between olfactory deficits and cognitive symptoms in schizophrenia, suggesting that this approach may yield valuable insights.
