Understanding Functional Movement Disorder: FAQs and Insights

Common Questions About Functional Movement Disorder

Functional movement disorder (FMD) involves abnormal involuntary movements such as jerking, tics, or tremors affecting limbs or the head. Unlike other movement disorders caused by brain or nerve damage, FMD arises from issues within nervous system functioning itself. Diagnosing FMD remains challenging, as standard tests often show no abnormalities, leading some to believe symptoms are imagined. However, these symptoms are real and persistent. Alternative terms include psychogenic movement disorder, nonorganic disorder, or conversion disorder. Explore the types, symptoms, diagnosis, and treatment options below.

There are several types of FMD, each with distinct features:

Functional Tremor – Representing nearly half of all FMD cases, this involves rhythmic muscle contractions causing oscillatory movements which can occur at rest or during activity, potentially spreading to other areas.

Functional Dystonia – Characterized by involuntary, repetitive muscle spasms and twisting movements, often patterned or tremulous.

Functional Myoclonus – Causes sudden, brief muscle jerks, often triggered by startling stimuli or sensory input.

Functional Parkinsonism – Less common, presenting with slow movements, tremors, speech issues, and gait disturbances, sometimes coexisting with Parkinson’s disease but distinct in origin.

Symptoms to Watch For

Weakness or paralysis in limbs

Numbness, tingling, muscle spasms, fatigue, head or limb pain

Sleep disturbances, poor concentration, slurred speech, blurred vision, feelings of unreality (derealization)

Gait problems and balance issues, often leading to falls

Seizure-like attacks that are non-epileptic

Emotional effects such as frustration, anxiety, and depression

Diagnosing FMD

Diagnosis involves detailed neurological and personal history, as FMD symptoms resemble other disorders.

Neurophysiological expertise and specialized tests, like electrodiagnostics or SPECT scans, aid in confirming FMD and ruling out organic causes.

Understanding neuroanatomy and neurophysiology is crucial for accurate diagnosis.

Available Treatments

Multidisciplinary approaches, primarily physical therapy, aim to restore movement and functionality.

Additional therapies include occupational therapy, psychotherapy, cognitive behavioral therapy, medications, and innovative methods like hypnosis or magnetic stimulation.

While prognosis can be challenging, these interventions often lead to symptomatic improvements.
