Dysgeusia Diagnosis and Management

Neurological Disorders

• Miller-Fisher Syndrome and polyneuritis cranialis can present with dysgeusia 1
• Neurological conditions like stroke, Parkinson's disease, and dementia may be associated with taste disturbances 2

Infectious and Inflammatory Causes

• COVID-19 infection frequently presents with dysgeusia, often associated with anosmia 1, 3, 4, 5

Diagnostic Testing Approach

• If neurological causes are suspected, cranial nerve assessment and potentially brain imaging 2
• In cases with concurrent dysphagia, videofluoroscopy or modified barium swallow may be indicated 6
• For suspected COVID-19, appropriate testing should be performed, especially with concurrent anosmia 1, 3, 4

Important Clinical Pearls

• Silent aspiration can occur in patients with dysphagia and associated dysgeusia, requiring careful evaluation 7
