Ketamine Therapy for Depression

When antidepressants and talking therapy haven’t been enough, KAP offers a different way in — combining a fast-acting medicine with the psychological work needed to make change stick.

Understanding Your Experience

Professional guidance in psychological care

If you’re reading this, there’s a good chance you’ve already tried more than one antidepressant, sat through months of CBT or counselling, and are still waking up under the same weight.

Roughly a third of people diagnosed with depression don’t reach full remission even after trying two or more antidepressants at an adequate dose — this is what’s clinically defined as treatment-resistant depression (TRD).

If that’s where you are, you’re not failing treatment — the treatment is failing to reach the part of the illness it needs to.

How KAP Works

The KAP Process

Ketamine creates a window of heightened neuroplasticity. Psychotherapy is what you walk through it with.

Rapid Neurochemical Shift

Ketamine acts on the glutamate system — not serotonin — rapidly increasing neural connectivity within hours rather than weeks.

Window of Plasticity

A short window opens where the brain is measurably more receptive to forming new patterns, loosening entrenched beliefs and cognitive rigidity.

Psychotherapy Integration

Structured therapeutic work — IFS, somatic approaches, integrative talking therapy — meets the brain in this receptive state to embed lasting change.

The Treatment Journey

What to Expect

A structured four-stage process, from first assessment to ongoing integration.

Assessment

A thorough medical and psychological screening with the clinical team and your therapist — to confirm KAP is appropriate and safe for you.

Preparation

You're guided through the process, setting intentions and building a trusting therapeutic relationship before treatment begins.

KAP Sessions

Four medically supervised treatment sessions delivered alongside professional support over the course of a month.

integration

Four integration sessions focused on processing and applying the insights from each KAP session to daily life change.

The Science

How Ketamine Works for Depression

Ketamine’s effects are neurological, structural, and psychological. Understanding what happens in the brain explains why conventional antidepressants often fall short.

Care approach

The Default Mode Network & Rumination

In depression, the DMN becomes chronically overactive — this is the neurological basis of the loop of negative, self-focused thought. Ketamine temporarily reduces this hyperactivity in a way no conventional antidepressant reliably achieves. Patients often describe a sudden loosening of that internal grip.

Glutamate, NMDA Receptors & Synaptic Renewal

By temporarily blocking NMDA receptors, ketamine triggers a rapid surge in glutamate that strengthens synaptic connections in key mood-regulating circuits — particularly in the prefrontal cortex. Effects are measurable within hours, unlike SSRIs which take weeks.

BDNF & Neural Regeneration

Chronic depression reduces levels of BDNF — a protein essential for neuron survival. Ketamine rapidly increases BDNF expression, triggering growth of new dendrites and synaptic connections. This supports durable change at the level of the brain’s physical architecture.

The Psychotherapy Window

The neurobiological effects converge to create a window of heightened neuroplasticity lasting hours to days post-session. During this window, entrenched negative schemas become more accessible. This is when KAP’s integration session does its most important work.

How quickly does ketamine work for depression?
Unlike conventional antidepressants, ketamine’s effects can often be felt within hours to days of the first session. Many patients report a noticeable shift in mood before a standard antidepressant would even begin to take hold.
The neuroplasticity window opened by ketamine typically lasts hours to days, which is why the integration psychotherapy in those days following the medicine session is so important. The therapeutic work done during this window supports longer-term and more durable change.
KAP is delivered under full medical supervision by a prescribing doctor and a qualified psychotherapist. All patients undergo a thorough medical and psychological assessment before any treatment begins. It is not suitable for everyone, which is why careful screening is part of the process.
Ketamine produces a dissociative, non-ordinary state — not recreational intoxication. You will be supported throughout by a trained therapist and in a medically supervised setting. Most patients describe the experience as unusual but manageable, and often meaningful.
The standard programme includes four KAP (medicine) sessions and four integration (therapy) sessions over the course of a month, alongside an initial assessment and preparation phase. Your team will discuss what’s appropriate in your individual assessment.
