作者的母亲在九年前被诊断患帕金森病，早期症状的存在时间更长[1]。到2017年，母亲的病情已进展至中期阶段[1]。作者两年前从上海移居悉尼，每年回访两次[1]。在与母亲的一次纸牌游戏中，作者发现了意想不到的现象：玩牌期间，母亲的手部稳定性、目光聚焦和心智敏锐度明显改善[1]。
游戏过程中，父亲试图暗中给母亲好牌，但母亲拒绝了这种帮助，这是她多年来首次表现出拒绝协助的意愿[1]。然而，这种改善并非持久。作者访问结束后，父亲告诉她，母亲参与纸牌游戏的频率已经下降，能够保持专注的时间也随之缩短[1]。这段经历表明，熟悉的活动虽然无法根治帕金森病，但能够在特定时刻穿透疾病的影响，暂时唤回患者的认知能力和个性特征[1]。
A woman diagnosed with Parkinson's disease nine years ago experienced a remarkable, albeit temporary, improvement in her cognitive and physical abilities when engaging in a familiar activity with her family.[1] The author, who relocated from Shanghai to Sydney two years ago and visits twice per year, observed that during card games, their mother's hand stability, focus, and mental sharpness noticeably improved.[1] The mother's condition had progressed to the mid-stage by 2017.[1]
During one of these card sessions, the mother demonstrated an unexpected independence when her husband attempted to slip her favorable cards—she refused the assistance, marking one of the first times in years she had rejected help.[1] However, the gains proved fleeting. After the author's visit concluded, their father reported that the mother's engagement with card games had diminished, with her ability to concentrate for sustained periods declining.[1]
