Thirty cases of amyotrophic lateral sclerosis patients were recruited from the neurology department of Ruijin Hospital, the pain department and the encephalopathy center of Luwan Branch of Ruijin Hospital. After the informed consent was signed, they were divided into a trial group and a control group. Each group contains 15 cases. The patients in the control group was treated with edaravone dissolved in saline during hospitalization, while the patients in the trial group was treated with edaravone, scopolamine, atropine and dexmedetomidine. Both groups of subjects were treated for 7 days within 3 weeks, followed by a buffer period of 3 weeks for observation, which was one treatment course. The total treatment protocol contains 3 treatment courses (or 18 weeks). Patients with amyotrophic lateral sclerosis were evaluated before treatment and 6, 12, 18, 24, 36, 48 weeks after treatment. The observations include whether the functional scores of patients with amyotrophic lateral sclerosis, Norris amyotrophic lateral sclerosis score, amyotrophic lateral sclerosis self-score, forced expiratory volume in one second, partial pressure of oxygen and maximum displacement of the hyoid were superior to those before treatment, and whether the partial pressure of carbon dioxide was inferior to those before treatment. Study hypothesis: Cholinergic receptor blocking therapy for amyotrophic lateral sclerosis is safe and effective in improving motor function and delaying disease progression in patients with amyotrophic lateral sclerosis.

Cerebral blood flow measurement, which is applied to patients with cerebrovascular-related diseases, provides useful information about hemodynamic status. There was a method using Doppler ultrasound and phase contrast (PC) MRI, but it was not widely used in clinical practice due to limitations in reproducibility between examiners, complexity of procedure, and time-intensive protocol. We intend to measure cerebral blood flow through the signal-intensity gradient (SIG) technique using Time-of-Flight (TOF) of brain magnetic resonance imaging, which can compensate for the shortcomings of the existing research methods. In addition, by analyzing the correlation with the previous methods, Doppler ultrasound and PC MRI, we will evaluate the effectiveness of our new method.
