Bipolar disorder

Bipolar disorder often begins with an episode of major depression before cycling into mania — a pattern that makes it one of the most complex and misunderstood mental health conditions to treat. In many patients, bipolar depression doesn’t respond well to standard medical care, leaving individuals caught in a relentless cycle of emotional extremes with no stable ground beneath them.

For those who have tried mood stabilizers, antidepressants, and conventional therapy without lasting relief, the frustration is not just emotional it is exhausting. Research shows that a significant portion of patients with bipolar disorder experience inadequate response to first-line treatments, underscoring the urgent need for alternative, evidence-based options.

Dr. Gino Ang and the team at the Ketamine Center of Connecticut specialize in ketamine infusions that safely and effectively treat bipolar depression, including cases that have not responded to traditional medications. To find out if you’re a good candidate for ketamine treatment, schedule an appointment at our Milford or Westport office today.

As symptoms lift, many patients describe…

Mood stabilization beginning, depressive episodes lifting, racing thoughts slowing, sleep regulation improving, energy balancing out, and clarity and focus returning. Improvement is measured with clinically validated rating scales, so progress is tracked rather than assumed.

How ketamine may help

By working on the glutamate system rather than serotonin, ketamine may offer rapid relief from the depressive phase — used as an add-on to your existing plan, never as a replacement for it. Treatment is delivered as a precise sub-anesthetic dose by a board-certified anesthesiologist, with hospital-grade Caretaker® monitoring throughout. We review your full medication list to build a safe plan, and we never recommend stopping prescribed care.

What treatment looks like

The standard protocol is a series of 6 infusions over about 12 days, each in a private room with dim lighting, music, and a clinician beside you the whole time. Most mood infusions take about 40–60 minutes, and many patients move to occasional as-needed booster infusions afterward to maintain results. Because ketamine is used adjunctively for bipolar depression, it always works alongside your existing care — never instead of it.

What many patients experience as symptoms begin to lift

The extreme highs and lows that once felt uncontrollable may soften significantly. Many patients describe a growing sense of emotional steadiness — not flat or numb, but balanced in a way they haven’t felt in years.

Feelings of heaviness, hopelessness, and emptiness often reduce quickly following ketamine infusion providing the kind of rapid relief that traditional antidepressants, which can take weeks, are unable to deliver at this speed.


The mental overactivity, restlessness, and intrusive thought patterns associated with bipolar disorder become easier to manage. Patients report a quieting of the mental noise that makes daily life so exhausting.

More consistent, restorative rest becomes possible as spiraling and intrusive thoughts begin to quiet. Improved sleep is one of the most commonly reported early benefits of ketamine therapy in bipolar patients.

Less exhaustion during depressive phases and less agitation during elevated states. Patients describe a more even, sustainable level of energy one that allows them to re-engage with work, relationships, and daily responsibilities.

Decision-making, concentration, and daily functioning often feel steadier and more reliable. Cognitive improvements are frequently reported as one of the most meaningful outcomes of treatment for patients with bipolar disorder.

Frequently Asked Questions

Bipolar disorder, also called manic depression, is a neurological condition that causes shifts in your energy, mood, and activity levels. Patients with bipolar disorder go through identifiable cycles of low mood (depression) and high-energy (mania).

The symptoms of mania include:
  • High activity level
  • Insomnia
  • Racing thoughts
  • Rapid speech
  • Feeling irritable
  • Risky behaviors (reckless driving, substance abuse, sexual encounters)
  • You may also experience hypomania, which means you have the same symptoms but they’re milder than full-blown mania.
Bipolar depression has the same symptoms as major depressive disorder. You may experience:
  • Low energy levels
  • Feelings of sadness and hopelessness
  • Loss of interest in activities
  • Changes in your sleep habits
  • Difficulty concentrating
  • Changes in your eating habits
  • Thoughts of suicide
Many patients with bipolar disorder go through depression before they experience a mood swing to mania or hypomania. Throughout their lifetime, they may spend more time depressed than having manic or hypomanic episodes.
Bipolar disorder is a lifelong condition that should be treated by a professional team of psychologists and psychiatrists. Treatment includes a combination of medications, such as mood stabilizers, atypical antipsychotics, and antidepressants, together with psychotherapy.
Antidepressants usually aren’t the first line of treatment for bipolar depression, however, due to concerns that they may exacerbate the disease. Ketamine is a safe and effective alternative to antidepressant medications.
Ketamine is highly effective for major depressive disorder and recommended as adjunctive therapy for patients with bipolar depression, especially when their depression doesn’t respond to psychiatric medications.
When the anesthesiologists at Ketamine Center of Connecticut administer intravenous (IV) ketamine, the medication improves nerve connections in your brain and has a direct effect on brain chemicals. Ketamine balances glutamate, and this, in turn, improves symptoms of bipolar depression.
Patients who respond to IV ketamine often experience symptom improvement within several hours. If you respond positively to your first two ketamine treatments, you’ll have a series of six total infusions. A series of treatments produces long-lasting results so you’ll only need occasional maintenance treatment.
