Background and Purpose: Neuropsychiatric symptoms (NPS) such as anxiety, depression, and delusions affect up to 90% of all patients with Alzheimer’s disease (AD). NPS is associated with significant caregiver burden and patient distress. Given the severe burden of NPS in AD, it is critical to know potential modifiable risk factors of NPS in AD. This study explores the association between hypertension and NPS in patients with drug-naive AD.
Methods : We reviewed medical records of 149 patients with AD with (n=80) and without (n=69) hypertension. NPS were assessed using the Korean version of Neuropsychiatric Inventory (K-NPI). Affective, psychotic, and behavior symptom clusters were assessed separately.
Results : The total score of K-NPI was not significantly different between patients with AD with and without hypertension. Among K-NPI domains, scores of depression/dysphoria (p=0.045), anxiety (p=0.022), and apathy/indifference (p=0.037) were significantly higher in patients with AD with hypertension. Systolic blood pressure (BP) was associated with higher total K-NPI and affective symptom cluster scores. Diastolic BP was associated with affective symptom cluster scores.
Conclusions : Results suggest that hypertension increases risk of specific NPS in patients with AD. Among NPS, hypertension was associated with affective symptom cluster.
