Using Glialia for Treating Persistent Perceptual Postural Dizziness

Официальное название

Use of the Glialia Supplement in the Treatment of Persistent Perceptual Postural Imbalance: A Triple-Blind, Randomized, Placebo-Controlled Pilot Clinical Trial

Обзор

This pilot study will involve 30 participants recruited from the Santa Lucia Foundation IRCCS, including 20 patients diagnosed with Persistent Perceptual Postural Dizziness (PPPD), and might or might not have previously contracted Sars Cov2 infection. They who will be randomly assigned to receive either the Glialia supplement or placebo. Additionally, 10 control participants who have recovered from COVID-19 will receive Glialia to help assess the influence of previous COVID-19 infection on neuroinflammation levels. The study aims to compare baseline neuroinflammation levels between PPPD patients and controls, measure changes in neuroinflammation in all groups after treatment and to determine if the reduction in neuroinflammation is more significant in the Glialia group compared to the placebo group. The trial will be conducted in a triple-blind manner, ensuring that neither participants nor researchers know the treatment assignments. Each participant will receive sachets to be taken daily for 60 days, with the study providing both the Glialia supplement and placebo at no cost.

Вмешательства

• Другое Glialia
  Participants in the PPPD-Glialia group will receive the Glialia supplement, which contains 700 mg of Palmitoylethanolamide (umPEA) along with 70 mg of additional supportive ingredients. Each participant will be instructed to take two soluble sachets daily for a total duration of 60 days. This group aims to evaluate the effects of Glialia on PPPD, with outcomes assessed for neuroinflammation, mental clarity, quality of life, balance, and gait quality.
• Другое Placebo
  Participants assigned to the PPPD-Placebo group will receive a placebo that is designed to be indistinguishable from the Glialia supplement in terms of appearance and packaging. They will also take two soluble sachets daily for 60 days. The purpose of this group is to serve as a control to evaluate the effects of the Glialia supplement by comparing the outcomes with those of the PPPD-Glialia group. The same assessments for neuroinflammation, mental clarity, quality of life, balance, and gait qua
• Другое Control
  Individuals in the Control Group will receive the same Glialia supplement as the PPPD-Glialia group, containing 700 mg of Palmitoylethanolamide (umPEA) and 70 mg of supportive ingredients. They will also take two soluble sachets daily for 60 days. The primary goal for this group is to assess how the Glialia supplement affects neuroinflammation and related outcomes in individuals who have recovered from COVID-19 but do not have PPPD. This comparison will help clarify the potential effects of Glia
