Name common etiologies of dysphagia in adults and their implications for management.

• A. Stroke; neurodegenerative diseases (ALS, MS, PD); head and neck cancer and treatment effects; TBI; myasthenia gravis; management ranges from compensatory strategies to rehabilitative therapy and nutrition support, guided by etiology and prognosis.
• B. GERD alone; requires no therapy.
• C. Only structural lesions.
• D. Pediatric conditions only.

Answer: (A)

The main idea is that adult dysphagia arises from a wide range of causes, and how we manage it depends on the exact etiology and prognosis. In adults, neurogenic problems from stroke or progressive neurodegenerative diseases (ALS, MS, Parkinson’s) can disrupt the coordination and strength of the swallow, so management often combines compensatory strategies (such as postural adjustments, timing of swallows, and texture-modified foods) with rehabilitative therapy when possible, plus nutrition support if safety is a concern. Cancer of the head and neck and the effects of its treatment can alter anatomy, sensation, and muscle function, leading to different swallowing difficulties that may require texture modification, swallow therapy, or feeding support. Traumatic brain injury adds another layer of motor control disruption, while autoimmune or neuromuscular disorders (like myasthenia gravis) can cause variable swallow weakness, guiding a mix of medical and swallowing interventions. Because the underlying cause shapes both prognosis and the best therapeutic approach, a comprehensive assessment that identifies the etiology is essential for tailoring treatment.

Other possibilities don’t capture this breadth. For example, swallowing problems aren’t explained by a single condition like GERD alone, and many patients require active therapy or nutrition support. Dysphagia is not limited to structural lesions, and adults are not best understood through pediatric conditions only.
