BACKGROUND/AIMS: Patients with idiopathic normal pressure hydrocephalus (iNPH) are often given shunt operations to reduce the triad symptoms (cognitive impairment, gait disturbance and urinary disturbance). We examined whether they also reduce caregiver burden.
The personal strain (PS) and role strain (RS) factors, which are related to the stress and constraints, respectively, on the caregivers of 81 iNPH patients were evaluated with the Zarit burden interview (ZBI) and each of the triad symptoms was evaluated with the iNPH grading scale (iNPHGS) before and 1 year after the shunt operation.
Each of the iNPHGS scores, the total ZBI score and PS factor significantly improved after the shunt operation, but the RS factor did not. The improvement of cognitive impairment was the major factor in reducing caregiver burden.
Shunt operations reduced the caregiver burden of iNPH patients.
背景/目的：特发性正常压力脑积水（iNPH）患者常接受分流手术以减轻三联征症状（认知障碍、步态障碍和尿失禁）。我们研究了分流手术是否也能减轻照料者的负担。
采用 Zarit 负担量表（ZBI）评估 81 例 iNPH 患者的照料者的个人负担（PS）和角色负担（RS）因素，这两个因素分别与照料者的压力和限制有关。在分流手术前和手术后 1 年，采用 iNPH 分级量表（iNPHGS）评估每个三联征症状。
分流手术后，iNPHGS 评分、ZBI 总分和 PS 因子均显著改善，但 RS 因子无改善。认知障碍的改善是减轻照料者负担的主要因素。
分流手术减轻了 iNPH 患者照料者的负担。
