Introduction

Positive feedback from a mental health treatment program that uses treatment adjuncts inspired researchers to assess the potential role of the Apollo Neuro device in mental health outcomes.

Objectives

To assess the impact of the Apollo Neuro device on anxiety levels in a ketamine-assisted therapy treatment program, comparing those using the device with those not using the device.

Methods

This is a quantitative study where the primary outcome measure was the change in Generalized Anxiety Disorder 7-item (GAD-7) scores, calculated as the difference between pre-GAD-7 and post-GAD-7 scores between patients with and without the Apollo Neuro device. Data cleaning was performed to handle missing values and non-numeric entries. Propensity score matching was used to match participants from the “Apollo” and “Control” groups based on demographic and baseline GAD-7 scores. An independent sample t-test was conducted to compare the mean change in GAD-7 scores between the two groups.

Results

Shapiro test did not suggest non-normality of GAD-7 change over the duration of the treatment program. Without pre-balancing of age/sex/pre-gad-7, an independent Welch Two Sample t-test was conducted to compare the mean change in GAD-7 scores between the two groups. There was no significant difference (p=.57).

Conclusions

Despite limitations of randomization and diversified participant groups, GAD-7 score analysis revealed median reduction in anxiety symptoms both with and without the Apollo Neuro device. Future research should further explore the effectiveness of the Apollo Neuro device in reducing anxiety symptoms, ideally through randomized controlled trials with larger and more diverse participant samples.
