Outcome Measures

Primary Outcomes (5)

  • Changes in Perfusion (Pre and Post Intervention)

    Compare brain function as measured with arterial spin labelling, functional near infrared spectroscopy pre and post intervention

    PRE = ~1 week before first intervention verses POST 1 = Immediately after 1st intervention/ POST 2 = after 6 weeks of TILS treatment

  • Changes in Resting State fMRI (Pre and Post Intervention)

    Compare brain function as measured with resting state fMRI pre and post intervention

    PRE = ~1 week before first intervention verses POST 1 = Immediately after 1st intervention/ POST 2 = after 6 weeks of TILS treatment

  • Changes in Resting State functional near-infrared spectroscopy (Pre and Post Intervention)

    Compare brain function as measured with near-infrared spectroscopy pre and post intervention

    PRE = ~1 week before first intervention verses POST 1 = Immediately after 1st intervention/ POST 2 = after 6 weeks of TILS treatment

  • Changes in task-based fMRI (Pre and Post Intervention): cognitive task with emotional distractors

    Compare brain function as measured with near-infrared spectroscopy pre and post

    PRE = ~1 week before first intervention verses POST 1 = Immediately after 1st intervention/ POST 2 = after 6 weeks of TILS treatment

  • Changes in task-based fMRI (Pre and Post Intervention): monetary reward and punishment

    Compare brain function as measured with near-infrared spectroscopy pre and post

    RE = ~1 week before first intervention verses POST 1 = Immediately after 1st intervention/ POST 2 = after 6 weeks of TILS treatment

Secondary Outcomes (1)

  • Changes in Composite Score of Cognitive Function

    PRE = ~ 1 week before first intervention verses POST after 6 weeks of intervention

Study Arms (1)

Intervention: Transcranial Infrared Laser Stimulation (TILS)

EXPERIMENTAL

Participants receive 10 minutes of TILS treatment to the right prefrontal cortex once a week for 6 weeks. TILS will use an FDA-cleared 1064-nm laser (CG-5000, Cell Gen Therapeutics, LLC, Dallas, TX). The irradiance will be 0.25 W/cm2, and fluence, 60 J/cm2.

Device: Transcranial infrared laser stimulation

Interventions

non-invasive, non-pharmacologic photobiomodulation device

Intervention: Transcranial Infrared Laser Stimulation (TILS)

Eligibility Criteria

Age18 Years - 78 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Able to read, speak, and understand English.
  • DSM-5 primary diagnosis of Bipolar Disorder type 1 or 2, by structured clinical interview (SCID-5).
  • Montgomery-Asberg Depression Rating Scale score ≤ 12.
  • Young Mania Rating Scale score ≤ 7.
  • On at least one anti-mania agent at a therapeutic dose for 6 weeks.
  • On stable doses of any standing psychotropics for 6 weeks.
  • Any standing benzodiazepine to a maximum dose equivalent to 22.5 mg oxazepam or 7.5 mg diazepam per day.

You may not qualify if:

  • Unable/unwilling to give informed consent.
  • Diagnosed with current primary psychotic disorder (rather than bipolar disorder).
  • Diagnosed with current manic/hypomanic or depressive episode.
  • Moderate to severe substance use disorder within the past 6 months (except nicotine, caffeine, cannabis).
  • Clinically defined major neurological disorder; including, but not limited to, seizure disorder and history of loss of consciousness due to head injury for greater than 10 minutes, or documented evidence of brain injury.
  • Active suicidal intent/plan as detected on screening assessments, or in the investigator's opinion is likely to attempt suicide within the next 6 months.
  • Clinically significant unstable medical condition.
  • If female: pregnant, not using medically acceptable birth control, or currently breastfeeding.
  • Other conditions judged by the investigator that could prevent the participant from completing the study (such as but not limited to, significant physical disability (e.g., hearing/visual deficits) to perform a neutral memory task and/or neuropsychological test battery).
