The researchers showed, for the first time, that striatal dysfunction was effective in distinguishing schizophrenia patients and that such dysfunction was also responsible for poorer antipsychotic response. This may be an important tool for objectively diagnosing and treatment response rather than the current approach, which primarily relies on the “softer” endpoint of patient behavior.
From the article:
The researchers showed, for the first time, that striatal dysfunction was effective in distinguishing schizophrenia patients and that such dysfunction was also responsible for poorer antipsychotic response.
Based on the newly developed biomarker, the researchers extended their research to other neuropsychiatric disorders. They showed that individuals with bipolar disorder also showed striatal dysfunction that overlapped with the dysfunction associated with schizophrenia.
