Parkinson’s disease non-motor symptom scales include Non-Motor Symptom Evaluation Scale, Olfactory Decrease Scale, and Parkinson’s Disease Sleep Scale. 1. Non-motor Symptom Evaluation Scale: This scale can be used as a screening tool for Parkinson’s disease before consultation by self-assessing the patient’s non-motor manifestations for one month, such as dizziness, sleep, mood, etc. It can assess the severity and efficacy of the disease. 2. Olfactory hyperalgesia scale: olfactory disturbances can appear before motor disturbances, and the use of this scale has early diagnostic value. 3. Parkinson’s Disease Sleep Scale: Parkinson’s disease sleep disorders are categorized into nighttime and daytime sleep disorders, and the severity of the disease can be assessed by evaluating the sleep disorders. In addition, the Parkinson’s disease non-motor symptom scales also include Hamilton depression scale, Beck depression scale, Parkinson’s disease cognitive function assessment scale, etc., which can assess the patient’s psychological state and cognitive ability. Appropriate use of the scales can help doctors to assess the patient’s status and intervene in a timely manner for related symptoms, which can not only improve the patient’s quality of life, but also reduce the social burden of the family. If patients experience similar symptoms, it is recommended that they seek medical attention in a timely manner to avoid delays.
