Brief Summary
To assess the effects of daily LFMS treatments for those suffering from affective or anxiety symptoms. We hypothesize a reduction in affective and or anxiety symptoms after active treatment over the period of one week, with improvement through the following week.

Interventions
The Low Field Magnetic Stimulation (LFMS) procedure is an application of a series of electromagnetic pulses to the brain. The field and timing parameters of the LFMS pulses, such as pulse timing, duration, frequency, and electric and magnetic field distribution and direction are different from other neurostimulation methods. LFMS electromagnetic fields are significantly weaker (\< 100x) than those used in ECT and rTMS.
Eligibility Criteria
You may qualify if:
- Subjects will be accepted into the study upon written referral by a McLean clinician or outside psychiatrist.
- Subjects will be men or women over the age of 18.
- Subjects must have failed at least one FDA approved treatment before enrolling in this study.
- Subjects must be capable of providing informed consent.
- Subjects must have either a Hamilton Depression Rating Scale (HDRS) score \> 14 indicating moderate depression or Hamilton Anxiety Rating Scale (HARS) score \> 18 indicating moderate anxiety.
You may not qualify if:
- Dangerous or active suicidal ideation.
- Pregnant or planning on becoming pregnant.
- Recent history (within 3 days) of ECT or TMS treatment.
- Substance abuse (cannot meet DSM criteria for substance abuse, no significant drug abuse within last 3 months, no history of dependence in last year, no drug use within last month, other than marijuana use).
- Current psychosis.
- Contraindications for MRI: Presence of a pacemaker, neurostimulator, or metal in head or neck.
- "Do Not Resuscitate" order in place (to avoid risk in the case of non-study-related accidents).
