Which of the following assessment tools is specifically designed to evaluate EPS?

The Simpson-Angus EPS Scale is specifically designed to evaluate Extrapyramidal Symptoms (EPS), which are drug-induced movement disorders commonly associated with the use of antipsychotic medications. This scale provides a systematic way to assess the severity of various EPS, including symptoms such as rigidity, tremor, and bradykinesia.

It is essential for clinicians to accurately identify and measure EPS since these symptoms can significantly affect a patient's quality of life and may require modifications in their treatment plan. The scale's focus on distinct motor symptoms makes it a targeted tool for this purpose, facilitating the appropriate response to these side effects in patients, particularly those on antipsychotic therapy.

In contrast, other assessment tools listed serve broader purposes. The Clinical Global Impression (CGI) is more general and evaluates overall severity of mental illness and treatment effect but does not focus on EPS specifically. The Positive and Negative Symptoms Scale (PANSS) is designed for general assessment of schizophrenia symptoms and looks at positive and negative symptoms, not exclusively EPS. Similarly, the Brief Psychiatric Rating Scale (BPRS) evaluates various psychiatric symptoms but does not specifically target EPS. Thus, the specificity and design of the Simpson-Angus EPS Scale distinguish it as the correct choice
