Hypermobile Ehlers–Danlos syndrome (hEDS) can lead to complex neurological symptoms that impact daily function and quality of life. In this article, you’ll learn about the neurological complications associated with hEDS, including craniocervical instability, Chiari malformation, MCAS-related symptoms, and other nerve-related concerns.

If you are experiencing headaches, dizziness, nerve pain, or cognitive changes related to hEDS, a specialized neurological evaluation is essential. Contact New York Neurology Associates today to schedule a comprehensive assessment and receive coordinated, multidisciplinary care tailored to your needs.

What is Hypermobile Ehlers–Danlos Syndrome?

Hypermobile Ehlers–Danlos syndrome (hEDS) is a connective tissue disorder that affects the structure and stability of the body’s joints, blood vessels, and skin. It can cause joint hypermobility and musculoskeletal pain. In addition, many patients experience neurological complications related to the effects of connective tissue fragility on the nervous system.

Understanding Neurological Involvement in hEDS

Because connective tissue provides structural support for the brain, spinal cord, and peripheral nerves, its laxity can lead to mechanical instability, nerve compression, and altered circulation. These effects can produce symptoms such as:

  • Chronic headaches or migraines
  • Neck pain and neurological sensitivity to movement
  • Tingling, numbness, or limb weakness
  • Dizziness, brain fog, and fatigue
  • Visual disturbances or balance problems
 

Many of these symptoms overlap with other disorders, making expert neurological evaluation essential for accurate diagnosis and targeted treatment.

Craniocervical Instability (CCI) and Chiari Malformation

Craniocervical instability (CCI) occurs when lax ligaments at the junction between the skull and cervical spine allow excessive motion that can compress the brainstem, spinal cord, or cranial nerves.

Common symptoms include:

  • Severe headaches, particularly at the base of the skull
  • Dizziness or balance difficulties
  • Nausea or visual changes
  • Neck pain and weakness
  • Fatigue or “brain fog”
 

Some hEDS patients may also develop Chiari malformation, in which a portion of the brain (the cerebellum) extends downward into the spinal canal, further aggravating pressure on surrounding nerves and cerebrospinal fluid flow.

We assist patients in obtaining appropriate imaging to detect this condition and assist by referring them to qualified specialists, including neurosurgeons, when appropriate.

Mast Cell Activation Syndrome (MCAS) and Neurological Symptoms

Mast Cell Activation Syndrome (MCAS)—frequently seen alongside hEDS—can influence the nervous system through inflammation and histamine release. Patients may experience:

  • Headaches and brain fog
  • Flushing, hives, or temperature sensitivity
  • Gastrointestinal disturbances
  • Tachycardia or lightheadedness
  • Worsening fatigue during allergic or inflammatory flares
 

We collaborate with allergy and immunology specialists to help patients identify triggers, manage inflammation, and stabilize symptoms through individualized care plans.

Other Neurological Concerns in hEDS

Patients with hEDS may also experience:

Diagnostic Approach

We offer advanced diagnostic testing and collaboration with other specialties to ensure a thorough assessment:

  • Neurological and musculoskeletal examination
  • MRI and dynamic imaging for CCI, Chiari, or tethered cord
  • Nerve conduction studies (NCS) and EMG for neuropathy
  • Autonomic testing for associated dysautonomia or POTS
  • Referral coordination with neurosurgery, immunology, and rehabilitation medicine

Individualized Treatment Plans

Treatment for neurological complications of hEDS may include:

  • Physical therapy to strengthen stabilizing muscles and protect joints
  • Pain management strategies, including nerve blocks or medication, where appropriate
  • Medication and diet modifications to manage MCAS and inflammation
  • Orthotic or bracing support for CCI and spinal instability
  • Collaborative surgical evaluation when noninvasive measures are insufficient
 

Our goal is to improve stability, relieve pain, and enhance each patient’s overall quality of life through personalized, evidence-based neurological care.

Patient Resources and Education

We encourage patients to explore reputable resources for education and community support:
