Bouwmans AEP et al. – Neurologists' intuition and clinical judgment alone are not accurate for detection of depression or cognitive impairment in patients with recent–onset parkinsonian symptoms because of low sensitivity despite of high specificity.
Methods- Two experienced neurologists took the history and examined 104 patients with a recent-onset parkinsonian disorder, and assessed the presence of depression and cognitive impairment.
- On the same day, all patients underwent a Hamilton Depression Rating Scale test, and a Scales for Outcomes in Parkinson's Disease-Cognition-test (SCOPA-COG).
- The sensitivity of the neurologists for the topic depression was poor: 33.3%.
- However, the specificity varied from 90.8 to 94.7%.
- The patients' sensitivity was higher, although the specificity was lower.
- On the topic CI, the sensitivity of the neurologists was again low, in a range from 30.4 up to 34.8%: however the specificity was high, with 92.9%.
- The patients' sensitivity and specificity were both lower, compared to the number of the neurologists.
