Details and patient eligibility

About

The purpose of the project is to assess the efficacy of parietal transcranial magnetic stimulation in misophonia. N=60 participants will undergo two transcranial magnetic stimulation sessions: one inhibitory and another excitatory. During both sessions, the parietal region will be stimulated. Participants will perform computerized tasks immediately before and after the stimulation, while EEG, heart rate, and skin temperature will be recorded. These recordings will be used to assess if TMS can be used to improve tolerance to misophonia triggers.

Enrollment: 60 estimated patients

Sex: All

Ages: 18 to 55 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Hypersensitive to presence of a specific sound, which may be accompanied by irritation, anger/outbursts, or fear.
• Must be between the ages of 18 - 55.
• Must be fluent in English since the study's instructions, surveys, and tasks will be in English.

Exclusion criteria

• Axis I Psychiatric condition, past or present, as defined in DSM-V.
• Disability or medical condition that prohibits completion of study. Participants must be able to complete all study procedures to ensure optimal conditions for data analysis.
• Central Nervous System (CNS) disease, such as history of brain abnormalities (e.g., neoplasms, subarachnoid cysts), cerebrovascular disease, infectious disease (e.g., abscess), or other neurological diseases, history of head trauma (defined as loss of consciousness>3 min), or history of seizures without a resolved etiology. CNS disease and drugs that act in the peripheral or central nervous system are likely to have effects on patterns of neural activity.
• Recent or regular use of psychotropic medication (e.g., amitriptyline for migraines).
• Recent use of drugs of abuse.
• Presence of any mental implants in the head.
• Pregnant or lactating.
