Postoperative patterns of improvement of symptoms and degrees of satisfaction in families of patients after operations for definite idiopathic normal pressure hydrocephalus: a long-term follow-up study

To clarify the patterns of improvement of pre- and post-operative symptoms and family satisfaction in patients with definite idiopathic normal pressure hydrocephalus (iNPN) who responded well to shunt intervention. The subjects included 40 patients definitively diagnosed with iNPH and who were follo...

Description
Summary:	To clarify the patterns of improvement of pre- and post-operative symptoms and family satisfaction in patients with definite idiopathic normal pressure hydrocephalus (iNPN) who responded well to shunt intervention. The subjects included 40 patients definitively diagnosed with iNPH and who were followed up for one year or longer (age, 61-85; male-to-female ratio, 18: 22). The study focused on (1) preoperative clinical symptoms, (2) improvements in symptoms at 1, 3, 5, and 12 months after surgery, and the satisfaction of the families based on medical results of the Zarit caregiver burden interview, and infomation through questionnaires to medical personnel. (1) The major symptoms were gait disturbance (G, n=38), dementia (D, n=10), and urinary incontinence (U, n=23). G and D appeared as initial symptoms in 30 and 10 cases, respectively. (2) The rates of postoperative improvement at 1, 3, 5, and 12 months were 94.7%, 94.7%, 97.4%, and 94.7% for G, 43.8%, 62.5%, 71.9%, and 84.4% for D, and 78.3%, 86.96%, 86.96%, and 91.3% for U, respectively. G and U cases improved during the postoperative early stage, and D improved gradually from after the third postoperative month. The family satisfaction before surgery and at 1, 3, 5, and 12 months after surgery was 72.5 +/- 12.8, 68.1 +/- 15.4, 55.7 +/- 9.6, 52.9 +/- 11.4, and 47.3 +/- 7.9 points, respectively. The rate of improvement in satisfaction was higher for D. The satisfaction of the medical personnel was 88 percent (+) at 1 month and tended to remain high for 12 months. (1) Preoperative gait disturbance is a major initial symptom in definitively diagnosed iNPN. (2) Postoperative improvement of G and U is obtained at an early stage. In contrast, D tends to improve gradually from after the third postoperative month. The family satisfaction increases as the symptom of D improve. The satisfaction of the medical personnel tends to remain high after the first postoperative month. This study investigated the results of quantitative analyses of the patients symptoms.
