Akathisia: More Than Restlessness – An Underrecognised Mental Health Crisis

Akathisia is one of the most distressing medication-induced conditions encountered in mental health care, yet it remains widely under-recognised and frequently misunderstood.

Derived from the Greek a-kathízein, meaning "to be unable to sit," akathisia is commonly described as a movement disorder characterised by an overwhelming sense of inner restlessness and an irresistible urge to move. However, this definition barely scratches the surface.

For many people, akathisia is not simply an inability to sit still—it is an intense neurological and psychological state that can completely overwhelm a person's ability to function.

What is akathisia?

Akathisia is most commonly associated with medications that affect dopamine pathways within the brain, particularly antipsychotic medications, although it may also occur with antidepressants (particularly SSRIs and SNRIs), anti-nausea medications, mood stabilisers, medication withdrawal, or changes in dosage.

Researchers believe the condition results from disruption to complex neurotransmitter systems involving dopamine, serotonin, noradrenaline and GABA, although the exact mechanisms are still not fully understood.

The hallmark feature is subjective inner restlessness—an unbearable internal sensation that often drives repetitive movement such as pacing, rocking, shifting weight, crossing and uncrossing the legs, or an inability to remain seated.

Importantly, the physical movements are only one part of the condition.

Many individuals experience:

• relentless internal agitation

• racing thoughts

• intrusive thoughts that feel frightening and completely out of character

• intense anxiety or terror

• profound irritability or rage

• an inability to relax, even when physically exhausted

• severe insomnia and fragmented sleep

• difficulty concentrating or processing information

• overwhelming feelings of dread or impending doom.

  
  

These experiences are not signs of personal weakness or "failing to cope." They are symptoms of a profoundly dysregulated nervous system.

Why is akathisia often missed?

One of the greatest challenges is that akathisia can closely resemble worsening anxiety, panic disorder, agitation, mania, or relapse of an underlying psychiatric illness.

As a result, individuals may be told they are simply anxious or that their mental illness is worsening, when in fact they are experiencing a serious adverse reaction to medication.

This can create a devastating cycle.

If akathisia is not recognised, additional medications may be prescribed or doses increased in an attempt to manage what appears to be escalating psychiatric symptoms. While these decisions are made with the intention of helping, they may inadvertently worsen the underlying akathisia if the condition itself has not been identified.

Greater awareness among prescribers, mental health professionals, emergency departments and families is essential.

The Human Experience

Imagine living an ordinary life and then, within days or weeks, feeling as though your own body has become uninhabitable.

You are exhausted, yet incapable of resting.

Your thoughts race relentlessly. Intrusive thoughts appear that bear little resemblance to your values or personality. Every fibre of your body feels activated, as though an internal alarm has become permanently switched on.

Many people describe wanting to "crawl out of their skin." Others speak of overwhelming dread, relentless panic, unbearable agitation or an inexplicable rage that never subsides.

Sleep, once a place of refuge, no longer offers relief. The boundary between wakefulness and rest becomes fractured. Days blur together as the nervous system remains locked in a state of relentless activation.

Activities that once felt ordinary—driving, shopping, being alone, or even leaving the house—may become impossible. Some individuals develop agoraphobic or monophobic symptoms, not because these conditions existed previously, but because nowhere feels safe when the source of danger appears to come from within.

For some, the suffering becomes so profound that suicidal thoughts emerge—not because they wish to die, but because they desperately want the torment to end. This is why akathisia should always be regarded as a medical and psychiatric emergency requiring prompt assessment.

The Cost of Not Being Believed

As human beings, we are wired to seek safety through connection.

During times of overwhelming distress, we need attunement, validation and compassionate care.

Sadly, many people living with akathisia describe a very different experience. They report feeling dismissed, misunderstood or having their symptoms attributed solely to anxiety or their underlying mental health condition. When a person's experience is repeatedly questioned or minimised, the isolation can become almost as painful as the condition itself.

Listening carefully, recognising the possibility of akathisia, and taking a person's experience seriously can profoundly influence both assessment and recovery.

Recovery Is Possible

Despite the severity of akathisia, recovery is possible.

The most important step is recognising the condition early and seeking prompt review by the prescribing clinician. Treatment varies according to the individual and may involve careful adjustment of medication and other evidence-based medical interventions. Medication should never be stopped abruptly without medical supervision.

Recovery often takes time.

For many people, the nervous system has endured weeks or months of relentless activation. During this period, reducing unnecessary stimulation, prioritising restorative rest, maintaining connection with trusted people, and engaging in gentle nervous system regulation and somatic practices may help support recovery alongside appropriate medical care.

Perhaps equally important is hope.

The nervous system possesses an extraordinary capacity to heal. Although recovery may not be linear, many people gradually regain their sense of calm, safety and trust in themselves.

Why This Matters

This article is not intended to create fear around psychiatric medication. Psychiatric medications have transformed—and continue to save—the lives of millions of people.

Rather, it is a call for greater awareness.

Every medication carries potential benefits and risks. While akathisia is relatively uncommon, its consequences can be profound if it is not recognised.

Earlier recognition. Better education. Careful listening. Compassionate assessment.

These are not simply good clinical practices—they have the potential to reduce unnecessary suffering and, in some cases, save lives.

The conversation around mental health must include not only the conditions we treat, but also the rare yet serious adverse effects of the treatments we prescribe. People experiencing akathisia deserve to be heard, understood and treated with the urgency and compassion this condition demands.

The information presented in this article is drawn from current psychiatric literature, clinical guidelines, and peer-reviewed research on akathisia. It is intended to increase awareness and understanding and should not replace individual medical advice.
