Understanding Conversion Disorder: When Anxiety Manifests as Neurological Symptoms

Dr. Tracey Marks elucidates Conversion Disorder, also known as Functional Neurologic Symptom Disorder, as a condition where individuals experience medically unexplained neurological symptoms believed to stem from psychological factors. These symptoms are distinctive because they lack physiological support from diagnostic tests, such as a normal electroencephalogram (EEG) in cases of pseudoseizures, and often present in ways that contradict typical neurological patterns. For instance, individuals with pseudoseizures might convulse bilaterally while remaining conscious, a physiological impossibility for true generalized seizures. The podcast stresses the involuntary nature of these symptoms, noting that they affect approximately 5% of patients seeking neurological care.

The episode traces the historical roots of the term "conversion disorder" to Sigmund Freud's psychoanalytic theory, which posited that unconscious psychological conflicts are transformed into physical representations. While contemporary psychiatry has evolved beyond a strict Freudian framework, the core concept of psychological distress manifesting somatically remains pertinent. A detailed case study of a patient named "Judy" vividly illustrates this phenomenon. Judy developed a complex array of neurological symptoms, including tremors, weakness, and numbness, following an accident involving her baby, compounded by guilt, anxiety, and marital discord, despite a thorough and normal medical workup.

From a practical standpoint, the podcast highlights the diagnostic complexity and the necessity of a holistic treatment approach. Judy's initial treatment with an antidepressant provided only partial relief for her mood and anxiety. Significant improvement occurred with intensive psychotherapy, which enabled her to connect her physical symptoms to her deep-seated guilt, fear, and unresolved emotional conflicts. The discussion emphasizes the efficacy of hypnotherapy, which ultimately helped Judy gain control over her symptoms, suggesting its potential as a valuable therapeutic modality. Additionally, treating co-occurring conditions like depression and anxiety is noted as a crucial step that can often alleviate conversion symptoms.

Conversion disorder encompasses a broad spectrum of symptoms, categorized into eight distinct types, including weakness or paralysis, abnormal movements, swallowing or speech problems, sensory loss, special sensory disturbances, and attacks or seizures, often presenting as mixed symptoms, as exemplified by Judy's case. The condition can manifest episodically or persist over time, and individuals may also experience dissociative episodes. This comprehensive analysis underscores the profound mind-body connection and the critical role of psychological factors in physical health, advocating for integrated mental health care that addresses both the somatic and psychological dimensions of such intricate disorders.

"Conversion disorder is also called functional neurologic symptom disorder. And this is where you could have medically unexplained neurological symptoms."

"The symptoms are thought to have a psychological basis because not only are they not supported by any tests, they usually have a little something off about them, such that they don't really match up with the way the disorder normally presents."

"a rule of thumb that cannot be broken is that once abnormal electrical activity crosses the midline and goes to from one side of the brain to the other, you lose consciousness. That's a physiological fact."

"But often people with pseudoseizures will convulse on both sides of their body while they're still awake."

"pseudo seizure symptoms are involuntary. People are not intentionally producing symptoms."

"The idea is that with conversion disorder, pseudo neurological symptoms arise when your mind converts unconscious psychological conflict into a physical representation of that conflict."

"Judy converted all of those unacceptable thoughts into physical symptoms that looked like a seizure and brain damage."

"Seeing these connections helped Judy see that her anxiety and worries were causing the symptoms, but the symptoms still didn't go away completely."

"It wasn't until she had some hypnotherapy that she was able to get control of the symptoms they mostly resolved, except for occasional times when she gets stressed out and have a mild hand tremor."

"Depression and anxiety commonly occur with conversion disorder. And sometimes treating the depression or anxiety can help the physical symptoms go away."
