Lance-Adams Syndrome: Symptoms, Classification, Diagnosis & Recovery

Diagnosing Lance-Adams Syndrome can be difficult due to the symptoms being similar to those of other movement disorders like epilepsy, Parkinson's disease, or cerebellar ataxia. A comprehensive neurologic evaluation and targeted diagnostic tests can help distinguish LAS from different conditions.

• Clinical History and Neurologic Examination: The physician initiates the evaluation with a complete medical history, noting any recent cardiac arrest, hypoxic event, or resuscitation for acute oxygen loss. The neurologic examination will evaluate muscle control, reflexes, and the individual’s coordination and shaking.
• Electroencephalography (EEG): An EEG provides a record of the electrical activity of the brain and is pertinent for ruling out epileptic seizures, which may also involve jerking. EEG in people with LAS may show cortical hyperexcitability without evidence of epileptiform discharges.
• Magnetic Resonance Imaging (MRI) and Computed Tomography (CT): MRI scans of patients with LAS may show hypoxic damage to specific brain structures, including the thalamus and cerebellum. CT scans help exclude structural brain lesions in an acute emergency setting.
• Electromyography (EMG): EMG evaluates the electrical activity of the muscle and helps identify the site and pattern of myoclonus.
• Neuropsychological Testing: Neuropsychological testing, focused on cognitive abilities such as memory, attention, and problem-solving, can be used to determine whether hypoxia has affected higher-level brain functioning.
• Laboratory and Metabolic Testing: Laboratory tests for serum electrolytes, liver and kidney function, or medication effects may help rule out an alternative cause of the myoclonus.

At MediRehab, our approach to managing Lance-Adams Syndrome focuses on relieving symptoms, improving mobility, and enhancing quality of life. While there is currently no cure for Lance-Adam’s Syndrome, a combination of medications, advanced therapies, and rehabilitation can help patients lead active and independent lives.

• Drug Treatment
  • Medications play a significant role in the management of Lance–Adams Syndrome.
  • Typically, drugs stabilise brain activation and support neurotransmitter function and muscle coordination. The combination and dosage of medications are unique to each patient, depending on symptom severity and/or response.
  • Medications are often used for long periods and require regular medical follow-up to ensure efficacy and limit the potential for side effects, including drowsiness, fatigue, or imbalance.
• Physical and Occupational Therapies: Rehabilitation seeks to retrain the muscles and brain to work in a coordinated way.
  • Physical Therapy: Patients will engage in strengthening, stretching, gait, and balance exercises to improve coordination and reduce stiffness.
  • Occupational Therapy: Patients also work closely with occupational therapists to relearn the process of completing daily activities such as dressing, eating, and even writing.
  • Constraint-Induced Movement Therapy: Patients are encouraged to use the affected limb in spontaneous ways, ultimately aimed at rebuilding neuroplasticity and regaining control.
• Speech and Swallowing Therapy: If facial or throat muscles are involved, speech-language pathologists support the production of speech sounds, ensure speech clarity, and improve swallowing function. Techniques may include breath control exercises, articulation practice, and/or adjustments in posture when talking or eating.
• Neurorehabilitation and Cognitive Therapy: Neurorehabilitation combines use of biofeedback, sensory retraining, and brain stimulation strategies to facilitate the brain's reorganisation of motor pathways. Cognitive behavioural therapy (CBT) can also help manage anxiety, frustration, or depression related to chronic symptoms.
• Advanced Therapies
  • Deep Brain Stimulation (DBS): Electrodes placed in specific areas of the brain work to regulate abnormal signals and control the myoclonus.
  • Transcranial Magnetic Stimulation (TMS): A noninvasive approach to stimulating brain areas associated with motor control.

At MediRehab, every Lance-Adam’s Syndrome recovery plan is designed with compassion, precision, and long-term care in mind, helping patients manage symptoms effectively and live life with confidence and dignity.

Recovery from Lance–Adams Syndrome is gradual and requires patience, commitment, and ongoing support from the rehabilitation team.

• Early Phase (First Few Weeks): The goal is stabilisation, controlling myoclonus, preventing contractures, and recovering basic motor control. Physical therapy begins gradually, with assisted movements and muscle re-education exercises.
• Intermediate Phase (1–3 months): Patients begin walking with support, perform self-care, and work on endurance. Pharmacotherapy is adjusted as needed to control tremors. Occupational therapy becomes an essential component to restore independence.
• Longer Term Recovery (3–12 months): Rehabilitation increases in intensity or frequency. Patients begin to exhibit voluntary movements, speak more clearly, and usually return to regular activities to some extent. Psychological therapy is available and appropriate to continue managing adjustment issues.

By the end of recovery, patients have varying amounts of time left. Still, it is not unusual for significant improvement to occur within 6–12 months with ongoing therapy and medication. Even with some residual tremor, a functional lifestyle frequently returns.
