Study: NCT05647473

Intervention type: BEHAVIORAL
Group type: EXPERIMENTAL
Intervention: Routine treatment
Description: Participants will be educated on ways to avoid induced hypotensive states, such as avoiding prolonged standing, standing after exercise, being nervous, eating several carbohydrate-rich foods, drinking alcohol, and being in a warm environment (such as a sauna). Participants will be encouraged in a comfortable home environment, such as a sit-down bath. If there are no contraindications, they are advised to increase their salt intake to approximately 10 grams per day and adjust their fluid intake to 2-3 liters per day. They will also be encouraged to perform lower-body strength training and moderate, non-strenuous activities. Seriously ill patients will be proposed to raise the head of their bed during sleep, wear tight clothing, eat small meals, and reduce alcohol intake.Concomitant treatment with cholinesterase inhibitors, memantine, or both was allowed.
