You walk into a room and forget why you’re there. You read the same sentence three times before it sinks in. You used to multitask without thinking, and now even a simple work email takes twice as long to write. If this sounds familiar, you’ve probably already searched “brain fog causes” more than once — and you’ve probably been told it’s stress, poor sleep, or just getting older.
Those things can absolutely play a role. But there’s a structure at the top of your spine that rarely makes the list, even though it sits at the literal crossroads of blood flow, nerve signaling, and brainstem function: the atlas vertebra, also known as C1. At Desoto Upper Cervical in Southaven, MS, Dr. David Hall and Dr. Troy Reistroffer specialize in identifying and correcting misalignments in exactly this area — and many of their patients are surprised to learn how closely their mental clarity is tied to what’s happening in their upper neck.

What’s Actually Happening in Your Brain When You’re “Foggy”?
Brain fog isn’t a diagnosis on its own — it’s a cluster of symptoms: sluggish thinking, trouble concentrating, word-finding difficulty, and a general sense that your mental “signal” is weak. Underneath those symptoms, three things typically need to be working well: steady blood flow to the brain, clear communication along the brainstem, and a nervous system that isn’t stuck in overdrive. When any of these get disrupted, the brain simply doesn’t have what it needs to fire efficiently, and fog sets in.
Why the Top of Your Neck Matters So Much
Here’s the part most people never learn: the vertebral arteries, which supply a significant portion of blood to your brain, don’t travel in a straight line down your neck. They weave through small bony tunnels in your cervical vertebrae and make a sharp turn right around the atlas before entering the skull. This is one of the most architecturally complex and vulnerable points in the entire vascular system.
The atlas also surrounds and protects the brainstem, the structure responsible for regulating heart rate, breathing, alertness, and the balance between your sympathetic (“fight or flight”) and parasympathetic (“rest and digest”) nervous systems. When the atlas shifts out of its normal position, even by a few millimeters, it can create tension on these arteries and irritation to the brainstem and surrounding nerve tissue. The result can be a sympathetic nervous system that runs in a chronically elevated state, which research has linked to reduced cerebral blood flow and the kind of mental sluggishness patients describe as brain fog.
None of this requires a dramatic injury. Years of forward head posture, a fender-bender you barely remember, an old sports injury, or simply how you slept for two decades can all gradually shift the atlas out of alignment without ever causing obvious neck pain.
How Dr. Hall and Dr. Reistroffer Locate and Correct the Misalignment
This is where upper cervical chiropractic differs meaningfully from general chiropractic care. Rather than adjusting the entire spine, Dr. Hall and Dr. Reistroffer focus exclusively on precisely measuring and correcting the alignment of the atlas using two specialized techniques: Atlas Orthogonal and Orthospinology.
Atlas Orthogonal uses detailed, precision imaging to calculate the exact angle, direction, and degree of misalignment, then delivers a gentle, sound-wave-based correction with no twisting, popping, or forceful manipulation. Orthospinology follows a similar diagnostic philosophy, using careful postural and structural analysis to identify how the atlas is sitting in relation to the rest of the spine and skull, then applies a precise, low-force correction designed to hold over time. Both approaches share the same underlying logic: the atlas is the master joint of the spine, and restoring its proper position can reduce the mechanical stress placed on the arteries, nerves, and brainstem structures running through that area.
What a Visit for Brain Fog Actually Looks Like
If you come into the Southaven office describing brain fog, the visit isn’t going to feel like a typical chiropractic appointment. Dr. Hall or Dr. Reistroffer will start with a detailed history, paying close attention to when your symptoms started and whether they coincide with any past head or neck trauma, even minor ones. From there, precise imaging is used to measure exactly how your atlas is positioned relative to your skull and the rest of your cervical spine.
If a misalignment is identified, the correction itself is quick, gentle, and doesn’t involve the cracking or twisting people associate with general spinal adjustments. Many patients are genuinely surprised by how subtle it feels. What follows tends to be more important than the correction itself: your body needs time to stabilize around the new position, which is why follow-up visits are spaced out to monitor your progress rather than repeated every few days.
It’s worth being direct about something here: upper cervical care isn’t a guaranteed fix for brain fog, and it isn’t meant to replace medical evaluation. Brain fog can stem from sleep disorders, thyroid issues, nutritional deficiencies, medication side effects, and a long list of other causes that fall outside the scope of chiropractic care. What Dr. Hall and Dr. Reistroffer offer is a thorough evaluation of one specific, often-overlooked contributing factor — a misaligned atlas — and a correction strategy if that factor is found to be present.
Is an Upper Cervical Evaluation Worth Considering for You?
You don’t need to have neck pain to have an upper cervical issue contributing to brain fog. In fact, many patients are surprised that their neck feels completely fine. Consider scheduling an evaluation if you experience any of the following:
- Persistent mental fogginess, sluggish thinking, or trouble concentrating that hasn’t improved with sleep, hydration, or stress management
- A history of whiplash, concussion, car accidents, or repeated minor head/neck impacts (even years ago)
- Brain fog that tends to worsen with poor posture, long periods at a desk, or looking down at a phone
- Co-occurring symptoms like dizziness, neck stiffness, headaches, or a feeling of pressure at the base of the skull
- Normal lab work and imaging from your medical doctor, but symptoms that persist anyway
- A general sense that something structural feels “off,” even without sharp pain
If several of these sound familiar, it may be worth having your upper cervical alignment evaluated alongside whatever else your medical team is exploring. Patients dealing with related symptoms like dizziness sometimes find it helpful to first read about the connection between vertigo and upper cervical misalignment, since the underlying mechanics often overlap with brain fog.
Frequently Asked Questions
Can a misaligned neck really cause brain fog?
It can be a contributing factor. The atlas vertebra sits directly around the brainstem and the vertebral arteries that supply blood to the brain, so a misalignment here can interfere with blood flow and nervous system regulation, both of which play a role in mental clarity. It’s rarely the only cause, but it’s one that’s frequently overlooked.
How is upper cervical chiropractic different from a regular chiropractic adjustment?
General chiropractic care typically addresses the spine broadly and may involve adjustments throughout the back and neck. Upper cervical chiropractic, using techniques like Atlas Orthogonal and Orthospinology, focuses precisely on the atlas (C1) using detailed imaging to calculate an exact, low-force correction rather than a generalized adjustment.
How many visits before I might notice a difference in mental clarity?
This varies significantly from person to person. Some patients notice subtle changes within the first few weeks, while others need more time for their nervous system to stabilize around the correction. Dr. Hall and Dr. Reistroffer will track your progress with follow-up imaging and symptom check-ins so you can see objective changes over time.
Is Atlas Orthogonal or Orthospinology better for brain fog symptoms?
Both techniques are built around the same goal: precisely correcting atlas misalignment with a gentle, low-force approach. Which one is used often comes down to your specific anatomy and what the imaging reveals. Dr. Hall and Dr. Reistroffer will determine the most appropriate approach during your evaluation.
Can children or teens experience brain fog from neck misalignment?
Yes. Falls, sports collisions, and even birth trauma can shift a child’s atlas out of alignment well before symptoms like difficulty concentrating show up. If a child or teen in your family struggles with focus alongside a history of head or neck impacts, an evaluation can help rule this in or out.
Should I see a medical doctor before trying upper cervical chiropractic for brain fog?
It’s a good idea to keep your medical provider in the loop, especially if your brain fog is new, severe, or accompanied by other concerning symptoms. Upper cervical chiropractic works well as a complementary part of your care, not a replacement for ruling out medical causes like thyroid dysfunction, sleep apnea, or medication side effects.
Does insurance cover an upper cervical evaluation?
Coverage varies by provider and plan. The Southaven office can review your specific benefits with you before your first visit so there are no surprises.
