Abstract

Objectives: In Parkinson´s disease, researchers are becoming increasingly aware of the need to include the assessment of behavioural and psychological symptoms as important outcome measures in clinical trials. Besides, clinicians are starting to recognise the need to identify and manage these symptoms in addition to the motor ones. Our objective is to explore the presence of neuropsychiatric symptoms in geriatric patients with Parkinson and the associated distress in their caregivers.
Methods: 100 patients with PD ageing 75 years old or more (50 PD without dementia and 50 PD Dementia (PDD) were assessed using the 10-item Neuropsychiatric Inventory-questionnaire (NPI-Q), and the NPI Caregiver Distress Scale (NPI-D).
Results: The mean total NPI score was 12.9. At least one neuropsychiatric symptom was present in more than 80% of participants. Within PDD patients about 89% suffered at least one NPI symptom, 70% suffered at least 2 symptoms and one of those symptoms had an intensity scoring 4 of higher in more than 50%. Numbers in PD patients without dementia were significantly lower, though more than 50% of patients had at least 2 symptoms. The most frequent symptom was depression, followed by apathy, anxiety, depression and hallucinations. Antiparkinsonian agents can exacerbate psychotic symptoms. Nearly 60% of caregivers reported suffering a moderate to severe level of stress due to these symptoms. Symptoms causing more stress were agitation/aggression followed by hallucinations and irritability/lability.
Conclusions: Neuropsychiatric symptoms are frequent in geriatric patients with PD –specially in patients with PDD– and lead to moderate to severe caregiver distress.
