Clinical Trial Summary

This is a randomized, double-blind, placebo-controlled clinical trial; that will evaluate the effectiveness of the use of transcranial pulse stimulation in people living with Alzheimer's disease, coming from the Institute of Psychiatry (IPQ) of the Hospital das Clinicas, Faculty of Medicine, University of São Paulo, and the Institute of Physical Medicine and Rehabilitation (IMREA) at the Hospital das Clínicas, Faculty of Medicine, University of São Paulo.

Participants will be classified according to the stage of Alzheimer's disease, determined by a psychiatrist and neuropsychologists. A total of 50 volunteers will be randomized blindly. In addition to evaluating the clinical course and imaging examination, the use of scales that assess functional and cognitive disability will be used for the recruitment of volunteers. Volunteers will be randomized into two study groups, and will receive the intervention that will consist of ten sessions, held twice a week. The Storz Neurolith™ equipment (Storz Medical, Tagerwillen, Switzerland) will be used to administer transcranial pulse stimulation.

Intervention

Other:
• Transcranial pulse stimulation (TPS)
Clinical treatment consists in ten sessions of neuronavigation system guided halocranial application of 6000 focused sound wave pulses, with energy flux density of 0.25 mJ/mm2, depth of focus of 5 cm and useful energy between 4 to 6 cm, frequency of 4 Hz, total energy applied will be 50 Joules, for it will be used the Storz Neurolith™ equipment.
