【 要旨 】 透析患者では,不眠,抑うつ症状などの精神症状を起こしやすく,QOL低下や死亡率の増加の一因となっている.原因は多彩で,腎不全・透析に関係する要因,むずむず脚症候群などの身体的要因に加え,心理社会的ストレス因子などさまざまな要因があり,これらの病態が重複して症状に関与している.治療は,内服加療の前に,生活環境や睡眠習慣の改善などの非薬物療法を積極的に行うべきである.高齢化が進んでいる透析患者では,薬剤蓄積により予期せぬ副作用を生じる可能性が高く,多剤併用は避けるべきである.向精神薬を使用する際には症状に応じて選択し,過剰投与にならないよう注意して使用することが重要である.

[ Summary ] Sleep disorders and depression are prevalent in maintenance dialysis patients and have been associated with decreased quality of life and increased morbidity and mortality. The reasons for the high prevalence of these disorders in patients on dialysis include potential intrinsic and environmental causes, such as kidney failure, dialysis, restless legs syndrome, psychosocial stress factors, and so on. These factors may overlap and cause refractory psychological symptoms. Although there is no consensus on a specific treatment for sleep disorders or depression in dialysis patients, it is recommended that non-pharmacologic approaches, such as improvement in sleeping habits and living environment, be used as a first-line approach. The average age of dialysis patients is increasing ; therefore, unexpected side effects of the drugs are likely to occur. Thus, multidrug combinations should be avoided. Psychotropic drugs and drug dosage should be selected based upon the patients' condition, to ensure the patient is not exposed to excess drug concentration.
