Akathisia is one of the most distressing yet underrecognized side effects of psychiatric and neurological medications. Characterized by an unbearable sense of inner restlessness and a compelling need to move, akathisia can feel like being trapped inside your own body. For individuals already managing conditions like depression, anxiety, or psychosis, the addition of akathisia can make treatment feel worse than the condition it was meant to address.
Despite its prevalence, akathisia is frequently misdiagnosed or dismissed—often mistaken for worsening anxiety, agitation, or noncompliance with treatment. Learning to recognize the symptoms, understand the causes, and advocate for proper management can make the difference between abandoning treatment entirely and finding a path forward that actually works.
What Is Akathisia?
Akathisia is a movement disorder most commonly triggered by medications that affect dopamine activity in the brain. The name comes from the Greek word meaning “inability to sit still,” and individuals who experience it describe an overwhelming internal urge to move that no amount of movement fully relieves. It is not simply restlessness or fidgeting—it is a deeply uncomfortable sensation that can provoke severe psychological distress.
The condition exists on a spectrum. Some people experience mild discomfort that is manageable with adjustments, while others develop acute akathisia so severe it leads to panic, emotional breakdown, or suicidal ideation. This wide range of severity is part of why akathisia is so frequently underdiagnosed. Clinicians who are not specifically looking for it may attribute the symptoms to the patient’s underlying psychiatric condition rather than to the medication itself.
What Causes Akathisia?
Akathisia is primarily a medication-induced condition, though it can occasionally occur in other contexts. The medications most commonly associated with akathisia affect the brain’s dopamine pathways, disrupting the balance between movement, reward, and emotional regulation.
Common medication triggers include:
- Antipsychotics: Both first-generation and second-generation antipsychotics are the most frequent cause, with drugs like haloperidol, aripiprazole and risperidone carrying significant risk
- Antidepressants SSRIs and SNRIs including sertraline, fluoxetine and venlafaxine can trigger akathisia, particularly during initiation or dose changes
- Anti-nausea medications: Metoclopramide and prochlorperazine act on dopamine receptors and are known triggers
- Mood stabilizers: Lithium and certain anticonvulsants have been associated with akathisia in some patients
- Stimulant medications: Drugs used for ADHD can occasionally produce akathisia-like restlessness
- Medication withdrawal: Abrupt discontinuation of benzodiazepines, opioids or certain psychiatric medications can trigger withdrawal-related akathisia
Types and Stages of Akathisia
Akathisia is not a single experience. It presents in distinct forms depending on timing, duration, and underlying cause. Understanding these variations is critical for accurate diagnosis and effective treatment.
| Type of Akathisia | When It Occurs | Key Characteristics |
| Acute akathisia | Within days to weeks of starting or increasing a medication | Sudden onset of restlessness, pacing, inability to sit still, intense inner agitation |
| Tardive akathisia | After months or years of sustained medication use | Develops gradually, may persist even after the medication is discontinued |
| Withdrawal akathisia | Following dose reduction or discontinuation of a medication | Emerges during tapering, often confused with relapse of the original condition |
| Chronic akathisia | Persists beyond three months regardless of medication changes | Ongoing distress that may require long-term management strategies |
| Pseudoakathisia | Presents with observable motor restlessness but without subjective inner distress | Patient exhibits repetitive movements but does not report the internal sensation of agitation |
How Akathisia Affects Mental Health
The psychological burden of akathisia extends far beyond physical discomfort. Because the restlessness is internal and difficult to articulate, many patients feel dismissed or misunderstood by clinicians and loved ones. This disconnect between the severity of the experience and the response it receives can amplify feelings of isolation, frustration, and hopelessness.
Akathisia has been directly linked to an increased risk of suicidal ideation, particularly in the early weeks of antidepressant or antipsychotic treatment. The sensation of being unable to escape one’s own body creates a unique form of psychological torment that can overwhelm existing coping resources. Patients who were previously stable may suddenly experience emotional volatility, panic, or a desperate urge to stop all medication without medical guidance.
The condition also undermines treatment adherence. When the medication prescribed to help feels like it is making everything worse, patients understandably lose trust in the treatment process. This often leads to abrupt discontinuation, which carries its own risks, including rebound symptoms and withdrawal syndromes.
How Akathisia Is Diagnosed and Treated
Diagnosis relies primarily on clinical observation and patient self-report, as there is no definitive lab test for akathisia. The Barnes Akathisia Rating Scale is the most widely used assessment tool, evaluating both objective restlessness and the patient’s subjective experience of inner distress.
Treatment approaches depend on the type and severity of akathisia. The table below outlines the most common management strategies.
| Treatment Strategy | How It Works | Best Suited For |
| Dose reduction | Lowering the dose of the triggering medication to reduce dopamine-related side effects | Acute akathisia with a clearly identified medication cause |
| Medication switch | Replacing the triggering drug with an alternative that carries lower akathisia risk | Patients who need continued psychiatric treatment but cannot tolerate current medication |
| Beta-blockers (propr | Reduces the physical sensation of restlessness by calming the autonomic nervous system | Acute and chronic akathisia, particularly when anxiety is prominent |
| Benzodiazepines | Provides short-term relief from agitation and inner restlessness | Severe acute episodes requiring immediate symptom management |
| Anticholinergic medications | Addresses movement-related symptoms by balancing dopamine and acetylcholine activity | Akathisia co-occurring with other extrapyramidal side effects |
Advocating for Yourself When You Suspect Akathisia
One of the greatest challenges with akathisia is that patients often lack the language to describe what they are feeling, and providers may not ask the right questions. If you suspect you are experiencing akathisia, being specific about your symptoms is essential. Describing the sensation as an internal restlessness that is separate from anxiety, noting when it began in relation to medication changes and communicating its impact on daily functioning can help your provider make an accurate assessment.
Keeping a symptom journal that tracks medication changes alongside restlessness levels, sleep quality, and emotional state provides concrete data that supports diagnosis. You have the right to ask questions about side effect profiles before starting any new medication and to request adjustments when something does not feel right.

FAQs
- What Does Akathisia Feel Like?
Akathisia is most often described as an intense inner restlessness that makes it impossible to feel comfortable in any position. Unlike ordinary restlessness, the sensation comes from inside the body and is not fully relieved by movement. Many patients describe it as feeling trapped, electrically charged, or driven to pace without knowing why.
- Can Antidepressants Cause Akathisia?
Yes, antidepressants—particularly SSRIs and SNRIs—are known to cause akathisia, especially during the first weeks of treatment or after a dosage increase. Medications like sertraline, fluoxetine, and venlafaxine are among the most commonly reported triggers. If restlessness develops shortly after starting or adjusting an antidepressant, it is important to report it to your prescriber immediately.
- Is Akathisia the Same as Anxiety?
Akathisia and anxiety share overlapping symptoms but are distinct conditions. Anxiety is typically driven by worried thoughts and fear, while akathisia is a physically driven sensation of restlessness that occurs independently of anxious thinking. Misdiagnosing akathisia as anxiety can lead to dose increases in the very medication causing the problem, which is why accurate differentiation is critical.
- How Long Does Akathisia Last?
The duration depends on the type. Acute akathisia often resolves within days to weeks once the triggering medication is adjusted or discontinued. Tardive and chronic forms can persist for months or longer and may require ongoing management. Withdrawal akathisia typically improves as the body stabilizes after medication discontinuation, though the timeline varies by individual.
- Can Akathisia Be Permanent?
In most cases akathisia is reversible with appropriate medication changes and management. However, tardive akathisia—which develops after prolonged medication use—can be more persistent and difficult to treat. Early recognition and intervention significantly improve outcomes, which is why reporting symptoms to a provider as soon as they appear is essential.
