Difficulty swallowing (dysphagia) means it takes more time and effort to move food or liquid from your mouth to your stomach. Dysphagia may also be associated with pain. In some cases, swallowing may be impossible.

Is dysphagia a neurogenic disorder?

Neurogenic dysphagia is characterized by problems with neural control of swallowing caused by various neurological diseases. The most common cause of neurogenic dysphagia development is a stroke [9, 10, 15, 16].

What is neurogenic oropharyngeal dysphagia?

Neurogenic oropharyngeal dysphagia is manifested mainly in the form of prolonged masticatory time,oral transit time, increased number of swallows required for each bolus, cricopharyngeal spasms and aspiration.

Which part of the brain is responsible for swallowing?

The medulla oblongata controls breathing, blood pressure, heart rhythms and swallowing. Messages from the cortex to the spinal cord and nerves that branch from the spinal cord are sent through the pons and the brainstem.

Is swallowing neurological?

Swallowing is complex process involving the coordinated interactions of a network of nerves and muscles, and a number of neurologic conditions can interfere with this process, causing disordered swallowing (dysphagia).

What causes delayed swallow?

A delayed pharyngeal swallow is an example of a disturbance in the sensory system, whereas reduced tongue control with premature spillage of material into the pharynx is an example of a disturbance in the motor system. Depending on the neurologic disorder, cognition may also be impacted.

What is a swallowing specialist called?

A Speech-Language Pathologist (SLP) is an expert in assessing swallowing disorders and establishing a treatment plan to improve the swallow. Your doctor or the SLP may recommend having a Modified Barium Swallow (MBS) evaluation where your swallow is viewed under x-ray to see how food or liquid is moving.
