Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this study was to clarify whether neck cooling can be used to non-invasively lower brain temperature in healthy adults.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Healthy adults were randomized to undergo an intervention in which either cold or body-temperature water was circulated through an adhesive wrap applied to the front of their necks, overlying the carotid arteries, for 120 minutes. After their first intervention, subjects crossed over (i.e., cold went to body-temperature, and vice-versa) on a separate day. Brain temperature was measured in one-minute intervals using MR thermometry.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cold circulated water

Cold water circulated through an adhesive wrap applied to the front of the neck.

Group Type EXPERIMENTAL

Cold circulated water

Intervention Type DEVICE

Cold water was circulated through an adhesive wrap applied to the front of the neck, overlying the carotid arteries, for 120 minutes. MR thermometry was used to measure core brain temperature in 1-minute intervals throughout the intervention. On a different day, subjects crossed over and repeated the intervention in the other study arm (i.e., cold went to body-temperature, and vice-versa).

Body-temperature circulated water

Body-temperature water circulated through an adhesive wrap applied to the front of the neck.

Group Type ACTIVE_COMPARATOR

Body-temperature circulated water

Intervention Type DEVICE

Body-temperature water was circulated through an adhesive wrap applied to the front of the neck, overlying the carotid arteries, for 120 minutes. MR thermometry was used to measure core brain temperature in 1-minute intervals throughout the intervention. On a different day, subjects crossed over and repeated the intervention in the other study arm (i.e., cold went to body-temperature, and vice-versa).
