Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Shortness of Breath
Difficulty breathing or feeling breathless, which may indicate brainstem involvement affecting respiratory control centers.
Seek immediate emergency care for sudden or severe difficulty breathing, as this can be life-threatening.
Dizziness
(neurologic)Feeling of lightheadedness, unsteadiness, or sensation of spinning (vertigo) due to brainstem involvement affecting vestibular pathways.
Frequency: 70-80% of patients
Difficulty Walking
(neurologic)Impaired coordination and balance (ataxia) making walking unsteady or requiring assistance.
Frequency: 65-75% of patients
Headache
(neurologic)Persistent or recurrent head pain, often described as dull, pressure-like, or throbbing in nature.
Frequency: 40-60% of patients
Difficulty Swallowing
(neurologic)Trouble swallowing (dysphagia) due to impaired function of cranial nerves controlling throat muscles.
Frequency: 35-50% of patients
Blurred or Double Vision
(neurologic)Visual disturbances including blurred vision, double vision, or difficulty focusing due to cranial nerve involvement.
Frequency: 30-45% of patients
Nausea
(gastrointestinal)Feeling of sickness with an urge to vomit, often associated with vestibular dysfunction in the brainstem.
Frequency: 25-40% of patients
Fatigue
(constitutional)Persistent tiredness, lack of energy, or feeling overly tired even after rest.
Frequency: 40-55% of patients
Slurred Speech
(neurologic)Speech that sounds unclear, slow, or difficult to understand due to impaired coordination of speech muscles.
Frequency: 30-45% of patients
Facial Numbness
(neurologic)Reduced sensation or tingling on one or both sides of the face due to cranial nerve involvement.
Frequency: 10-20% of patients
