Neuropsychiatric symptoms and executive dysfunction are highly prevalent in advanced Parkinson's disease (PD), particularly among institutionalized patients, yet evidence for structured rehabilitation in this population remains limited. We conducted a 3-month longitudinal pilot study in nine institutionalized patients with clinically established idiopathic PD according to Movement Disorder Society criteria. Participants received a weekly 45-min composite music-based recreational program incorporating stretching, perioral and pharyngeal exercises, and singing with coordinated movements. Mood was assessed using the Profile of Mood States 2 (POMS-2), and executive function was evaluated using the Frontal Assessment Battery (FAB) at baseline and post-intervention. Significant improvements were observed in POMS-2 subdomains of anger-hostility (p = 0.014), while Total Mood Disturbance and other subdomains showed a trend toward improvement. Executive function did not significantly improve at the group level (p = 0.240); however, change in FAB was significantly correlated with change in Total Mood Disturbance (r = 0.677, p = 0.023). These findings suggest that a feasible music-based recreational program may modulate negative mood states in institutionalized patients with advanced PD and highlight a potential relationship between affective and executive changes warranting further investigation.
