Prognosis for<unk>  patients is poor.<unk>  symptoms can include progressive difficulty with talking and swallowing. Patients can also exhibit reduced gag reflexes, weak palatal movements, fasciculations, and weak movement of the facial muscles and tongue. In advanced cases of<unk> , the patient may be unable to protrude their tongue or manipulate food in their mouth. Patients with early cases of<unk>  have difficulty with pronunciations, particularly lateral consonants (linguals) and velars, and may show problems with drooling saliva. If the corticobulbar tract is affected a pseudobulbar affect with emotional changes may occur. Because<unk>  patients have such difficulty swallowing, food and saliva can be inhaled into the lungs. This can cause gagging and choking, and it increases the risk of pneumonia. Death, which is often from pneumonia, usually occurs 1 to 3 years after the start of the disorder. About twenty-five percent of patients with<unk>  eventually develop the widespread symptoms common to ALS.
