(neurologic)Diagnosis and tests
How this condition is diagnosed and what test results mean.
Initial screening tests
Standard diagnostic workup
Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Disease-modifying pharmacotherapy
Riluzole or other approved agents that may modestly slow disease progression by reducing glutamate excitotoxicity. Treatment aims to preserve motor function and extend survival.
Medication management with follow-up
Active treatment with regular monitoring by a healthcare provider is recommended.
Motor function preservation program
Specialized physical therapy focusing on maintaining muscle strength, joint mobility, and preventing contractures. Exercise programs are tailored to preserve function while avoiding overexertion.
Additional treatment options
Symptom management medications
Pharmacological management of symptoms including muscle cramps, spasticity, fatigue, and pseudobulbar affect using appropriate agents as needed.
medicationPsychological support and counseling
Mental health support including counseling, support groups, and when indicated, pharmacological treatment for depression and anxiety associated with chronic progressive illness.
psychologicalRespiratory support planning
Proactive planning for respiratory involvement including pulmonary function monitoring, cough assist devices, and timely discussion of non-invasive ventilation options.
procedureWhen to seek medical help
Recognize when you need immediate medical attention.
See a doctor within 24 hours
Moderate to severe symptoms that may indicate worsening of this condition. Prompt medical evaluation is recommended.
Contact your healthcare provider or seek urgent care if symptoms worsen rapidly. Go to the emergency department for life-threatening symptoms.
