    Functional Neurological Disorder (FND)

    If you are experiencing symptoms like tremors, weakness, or seizures—yet your MRIs and EEGs come back 'normal'—you are likely dealing with Functional Neurological Disorder. We specialize in bridging the gap between physical symptoms and brain-network function.

    Targeted Diagnosis: Understanding the "Software" of the Brain

    FND is often described as a "software" problem rather than a "hardware" problem. The structure of the brain is intact, but there is a disruption in how the brain sends and receives signals.

    Functional Movement Disorders

    Includes persistent tremors, dystonia (posturing), or gait abnormalities that may change with distraction.

    Functional Limb Weakness

    A real experience of paralysis or weakness that does not follow traditional nerve-pathway damage but is detectable through clinical signs like 'Hoover's Sign.'

    Non-Epileptic Seizures

    Episodes that look like epilepsy but are caused by the brain's response to internal or external triggers rather than electrical 'storms.'

    Sensory & Cognitive Symptoms

    Numbness, tingling, 'brain fog,' or vision changes that fluctuate in intensity.

    Precision Treatments: The Three-Pillar Recovery Roadmap

    Because FND involves the brain's signaling pathways, treatment focuses on "retraining" the nervous system. Dr. Karmazin utilizes a multi-disciplinary approach.

    Diagnostic Clarity & Education

    Understanding Your Condition

    • Validation: Moving away from 'it's all in your head' to 'your brain's signaling is misfiring'
    • Symptom Mapping: Identifying the 'loops' in the nervous system that keep symptoms active

    Neuro-Modulatory Strategies

    Stabilizing the Nervous System

    • Symptom Management: Targeted medications to address pain, anxiety, or sleep disturbances
    • Neuromodulation Education: Non-invasive tools to help 'reset' sensory-motor pathways

    Physical Interventions

    Rewiring the Path

    • FND-Specific Physical Therapy: 'Retraining' the brain through movement with distraction and relearning automatic patterns
    • Speech & Occupational Therapy: For functional speech changes or difficulties with daily tasks
    • Lifestyle Stabilization: Regulated breathing, pacing, and stress-reduction techniques

    The Private Practice Advantage: Virtual FND Care

    Patients with FND often face "medical gaslighting" in large hospital systems. In Dr. Karmazin's private practice, you receive the time and specialized attention required to treat this complex condition.

    Personalized Attention

    A board-certified neurologist who understands FND is a physical, biological condition.

    Direct Observation

    Virtual visits allow Dr. Karmazin to see your symptoms in your natural, low-stress environment.

    Long-Term Coordination

    We don't just diagnose; we manage your care team (PTs, therapists) over the long term.

    Virtual Accessibility

    Avoid the stress of travel, which is a common trigger for functional symptom flares.

    Need Workplace Accommodations?

    Dr. Karmazin provides ADA accommodation letters, FMLA certification, and disability documentation for patients with this condition.
