Dysphagia has many possible causes and happens most frequently in older adults. Any condition that weakens or damages the muscles and nerves used for swallowing may cause dysphagia. For example, people with diseases of the nervous system, such as cerebral palsy or Parkinsonâs disease, often have problems swallowing.
Stroke and Dysphagia. A stroke occurs when the blood supply to part of your brain is interrupted or severely reduced, depriving brain tissue of oxygen and nutrients. Within minutes, brain cells begin to die. Stroke can affect the areas of the brain that control the muscles of chewing. This causes difficulty generating a mass of food that is soft and small enough to be swallowed. Indirectly, this leads to dysphagia. This is why for many people, jaw exercises can dramatically improve the ability to swallow.
