Nervous System Dysregulation Test: Hyperarousal, Hypoarousal, Recovery
A self-assessment that takes the popular idea of a "dysregulated nervous system" and gives it an honest, specific test: your pattern across hyperarousal (revved up), hypoarousal (shut down), and how quickly you recover after stress. We also explain plainly what the science does and doesn't support.

Nervous System Dysregulation Test is a free, confidential 24-question self-assessment, educational screener, not a diagnostic test. It takes about 6 minutes, runs entirely in your browser, and gives you a plain-language score across 3 interpretation bands plus an optional in-depth report. It is an educational screening, not a diagnosis.
Three patterns behind the popular term "dysregulated"
"Nervous system dysregulation" is everywhere online, often without a clear definition. This test breaks the idea into three concrete patterns: running hot (hyperarousal), running low or shut down (hypoarousal), and how quickly you settle again after stress (recovery).
Hyperarousal
Signs of running "revved up": a racing heart, being easily startled, irritability, restlessness, and trouble sleeping because your body won't settle.
Hypoarousal
Signs of running low or shut down: numbness, heavy fatigue, mental fog, and going quiet or blank under stress instead of reacting.
Recovery
How quickly, or slowly, your body and mind settle back down once a stressful moment has actually passed.

How scoring works
Answers are scored 0–96 in total. Your result falls into one of 3 bands:
| Score | Band | What it suggests |
|---|---|---|
| 0–31 | Mostly regulated | Your answers show few signs of the hyperarousal, hypoarousal, or slow-recovery patterns this checklist tracks: your reactions to stress and how quickly you settle both look steady. |
| 32–63 | Often activated | Your answers show a pattern of running hot, shut down, or slow to recover more than you'd like, without it fully taking over your life yet. |
| 64–96 | Frequently dysregulated | Your answers show a pattern of running hot, shut down, or slow to recover often enough that it's likely affecting your daily life. |
How the Score Is Calculated
This test has 24 original statements, eight for each of three patterns: hyperarousal, hypoarousal, and recovery. Each is rated from 0 (never) to 4 (almost always) based on the past month, so each pattern can total up to 32 points, for a combined score from 0 to 96. Hyperarousal and hypoarousal can seem like opposites, running hot versus running low, but many people show real signs of both at different times, sometimes even within the same day, which is why they're scored and shown separately rather than canceled out against each other.
The recovery subscale is scored the same way but asks a different question: not how intense your reactions are, but how long it takes your system to settle back down once a stressful moment has passed. Two people with similar hyperarousal scores can have very different recovery scores, and recovery speed is often the more useful thing to track over time as you work on regulation.
"Dysregulation" Isn't a Diagnosis: What the Term Actually Maps To
"Nervous system dysregulation" is a popular wellness term. It is not a clinical diagnosis: it does not appear in the DSM-5-TR or in the ICD-11, it has no diagnostic criteria, and there is no validated instrument that measures it as its own condition, this test included. That doesn't mean the underlying experience isn't real; it usually maps to well-studied clinical concepts like the hyperarousal criteria in PTSD (American Psychiatric Association, 2022), general stress-response physiology, and, for some people, symptoms of anxiety or a trauma-related condition. Treat this test as a symptom checklist for self-reflection, a way to name a pattern in your own words, not as evidence of a diagnosable condition. It points you toward the more specific, validated screeners where a pattern here looks like it might be part of something like PTSD or anxiety.
It's also worth knowing that some of the specific claims floating around online about the vagus nerve and "polyvagal theory", which many popular nervous-system content creators build on, are genuinely and increasingly contested within the scientific community. Stephen Porges proposed the theory in detail (Porges, 2007), and it has been influential in trauma-informed therapy circles, but physiologist Paul Grossman and colleagues published a detailed critique in 2023 arguing several of its core physiological claims aren't well supported by the anatomical and cardiovascular evidence (Grossman, 2023). That critique has since hardened: in 2026, Grossman and 38 other researchers published a joint expert evaluation concluding plainly that "the polyvagal theory is untenable" (Grossman et al., 2026), and Porges published a scholarly response defending the theory the same year (Porges, 2026). Reasonable experts still disagree. You don't need to resolve that debate to find a regulation practice useful; you should just know that some of the specific mechanisms cited online are far more contested than they're usually presented as, and that this page describes your pattern in plain language rather than leaning on any single, disputed mechanism.
How This Overlaps With Stress, PTSD, and Anxiety
A dysregulated-feeling nervous system rarely shows up alone. It commonly overlaps with high general stress, with PTSD and complex trauma, where hyperarousal is a core diagnostic feature, and with anxiety disorders, where the body's threat-detection system runs more sensitively than the situation calls for. If your hyperarousal score is your highest, our Anxiety Test (/tests/anxiety) or PTSD Test (/tests/ptsd) may describe your experience more precisely. If your hypoarousal and freeze-like patterns stood out, our Trauma Response Test (/tests/trauma-response) looks specifically at fight, flight, freeze, and fawn patterns, which often sit right alongside this.
Chronic overall strain, regardless of the specific pattern, is also worth checking against our Burnout Test (/tests/burnout) and Stress Level Test (/tests/stress-level), since sustained stress is one of the most common everyday causes of a nervous system that doesn't settle easily.
What Actually Helps Regulate the Nervous System
Regardless of the scientific debate over the exact mechanism, a consistent set of practices shows up across the research on stress-response regulation: slow, extended exhale breathing, regular physical movement, consistent sleep and daylight exposure, safe social connection, and, for many people, structured approaches like cognitive behavioral therapy or somatic therapy. None of these require you to fully understand or agree with any particular theory of how the vagus nerve works; they're supported by broader evidence on stress physiology and nervous system regulation independent of that debate.
If patterns here feel severe, longstanding, or connected to a trauma history, working with a clinician who specializes in trauma or anxiety will get you further than self-directed practice alone. Our stress management tool (/tools/stress-management) is a good place to start building a regulation practice today.
Methodology & sources
The 24 items in this test are original, written to describe three concrete, observable patterns commonly grouped under the popular term "nervous system dysregulation": hyperarousal, hypoarousal, and recovery speed. "Nervous system dysregulation" is not a diagnosis in the DSM-5-TR or the ICD-11, has no diagnostic criteria, and has no validated instrument behind it. This test is a symptom checklist for self-reflection, not a clinical scale: its items map loosely onto the hyperarousal criteria used in PTSD diagnosis (American Psychiatric Association, 2022) and onto general stress-response research, rather than reproducing any single validated psychometric instrument.
We deliberately included an honest discussion of contested science, because a lot of popular content about the nervous system presents polyvagal theory as settled fact. Stephen Porges's polyvagal theory (Porges, 2007) has been genuinely influential in trauma-informed care. Paul Grossman published a detailed physiological critique in 2023, and in 2026 he and 38 other researchers published a joint expert evaluation concluding that the theory "is untenable" (Grossman et al., 2026); Porges published a scholarly response the same year defending the theory (Porges, 2026). This test does not take a side in that live scientific debate; it describes your pattern using accessible, non-diagnostic language and points you toward validated, specific screeners where your results suggest a closer look is warranted.

Nervous System Dysregulation Test FAQ
What does 'nervous system dysregulation' actually mean?
It's a popular, non-clinical term for a nervous system that has trouble settling back to a calm baseline, whether that shows up as running "revved up" (hyperarousal), running low or shut down (hypoarousal), or taking a long time to recover after stress. It isn't a formal diagnosis, but the underlying experience often maps to well-studied concepts like PTSD hyperarousal or general stress physiology.
Is polyvagal theory scientifically accepted?
It's influential, especially in trauma-informed therapy, but genuinely and increasingly contested among researchers. Stephen Porges proposed it in detail in 2007, physiologist Paul Grossman published a substantial critique in 2023, and in 2026 Grossman and 38 other researchers published a joint expert evaluation concluding that the theory "is untenable"; Porges published a scholarly response defending it the same year. Reasonable experts disagree, which is part of why we describe this test's results in plain, accessible language rather than citing specific polyvagal mechanisms as settled fact.
Can I be both hyperaroused and hypoaroused?
Yes, and many people are, sometimes shifting between the two within the same day or even the same difficult conversation. That's part of why this test scores them as two separate patterns rather than opposite ends of one scale.
Is this test a diagnosis?
No. It's an educational screening tool for self-reflection, not a diagnosis. "Nervous system dysregulation" is not a condition in the DSM-5-TR or the ICD-11, has no diagnostic criteria, and has no validated instrument; think of this as a symptom checklist, not a clinical scale. If your pattern looks like it overlaps with PTSD, anxiety, or another condition, this page links to the more specific, validated tests for that.
What actually helps a dysregulated-feeling nervous system?
Slow exhale-focused breathing, regular movement, consistent sleep, safe social connection, and, for many people, structured therapy like CBT or somatic therapy. These are supported by broader stress-physiology research independent of any single theory of how the mechanism works.
