Neuropsychological Assessment in Elderly Men with Benign Prostatic Hyperplasia Treated with Dutasteride

Background and Objective
Benign prostatic hyperplasia (BPH) is a common disease found in elderly men and 5α-reductase (5α-R) inhibitors are a commonly used treatment option. 5α-reduced steroids are compounds that play a role in several functions across different organs and systems. In the adult brain, 5α-R accounts for neuroactive steroid production. Whether neuropsychological impairment could be due to dutasteride treatment, a 5α-R inhibitor affecting the production of dihydrotestosterone (DHT), is still unknown. The aim of our study was to investigate neuropsychological features in men receiving dutasteride.
The Mini Mental State Examination (MMSE), the Clock Drawing Test (CDT), the Frontal Assessment Battery (FAB), the Hamilton Anxiety Rating Scale (HAM-A), the Beck Depression Inventory second edition (BDI-II) and the Short Form-12 (SF-12) questionnaire were administered in order to explore both cognitive impairment and psychological features.
In a sample of BPH patients (n = 40; mean age 71.4 ± 7.4 years), men receiving dutasteride showed no significant differences during the neuropsychological assessment in comparison with an age-matched control group, consisting of BPH men not receiving dutasteride (p < 0.05). No significant associations were recorded between treatment duration and any of the administered tests.
This is the first study investigating the neuropsychological features in dutasteride users. Our preliminary data are consistent with the safety of dutasteride under a mental profile.
