Abstract

BACKGROUND

The objective of this study was to evaluate whether the sensation of thirst differs between patients with progressive supranuclear palsy (PSP), multiple system atrophy with predominant parkinsonism (MSA-P), and Parkinson's disease (PD).

METHODS

We administered a standardized thirst questionnaire to age-, sex-, and stage-matched patients with probable PSP, PD, and MSA-P and healthy controls (HC), n = 15/group. In an independent cohort (n = 10/group), we provoked thirst by infusing hypertonic NaCl in age-, sex-, and stage-matched patients with PSP, PD, and MSA-P and recorded plasma osmolality and thirst (visual analog scale).

RESULTS

On questioning, 73% of PSP patients reported a reduced sensation of thirst (hypodipsia) compared with previous years (HC, 0%; PD, 7%; MSA-P, 7%; P < .0001). On NaCl infusion, PSP patients reported significantly lower thirst than did PD and MSA-P patients for all times from 20 to 95 minutes (P < .05). The thirst score at 25 minutes discriminated individual PSP patients well from PD and MSA-P patients.

CONCLUSIONS

Hypodipsia appears helpful in differentiating PSP from PD and MSA-P.

摘要

背景

本研究旨在评估进展性核上性麻痹（PSP）、以帕金森病为主的多系统萎缩（MSA-P）和帕金森病（PD）患者的口渴感是否存在差异。

方法

我们对年龄、性别和分期匹配的可能 PSP、PD 和 MSA-P 患者以及健康对照者（HC）进行了标准化口渴问卷评估，每组 n = 15。在独立队列中（n = 10/组），我们通过输注高渗 NaCl 来诱发口渴，并记录血浆渗透压和口渴感（视觉模拟评分）。

结果

在询问时，73%的 PSP 患者报告口渴感降低（渴感减退），与前几年相比（HC，0%；PD，7%；MSA-P，7%；P <.0001）。在输注 NaCl 时，PSP 患者在 20 至 95 分钟的所有时间点报告的口渴感明显低于 PD 和 MSA-P 患者（P <.05）。25 分钟时的口渴评分能够很好地区分 PSP 患者与 PD 和 MSA-P 患者。
