Signs and symptoms

Common signs and symptoms that may indicate this condition.

Warning signs - seek immediate care

!

Seizures

Sudden, uncontrolled electrical disturbances in the brain causing convulsions or loss of consciousness.

Seek emergency care immediately for any seizure lasting more than 5 minutes or if it's the first occurrence.

!

Altered mental status

Confusion, disorientation, or changes in consciousness ranging from mild to severe.

Seek emergency care immediately for sudden confusion, hallucinations, or unresponsiveness.

Chronic fatigue

(neurologic)

Persistent tiredness and lack of energy that does not improve with rest, often interfering with daily activities.

Frequency: 70-80% of patients

Headache

(neurologic)

Recurrent headaches ranging from mild to moderate intensity, often described as dull or pressure-like.

Frequency: 50-60% of patients

Nausea

(gastrointestinal)

Feeling of sickness with an urge to vomit, which may occur intermittently or after meals.

Frequency: 40-50% of patients

Skin rash

(dermatologic)

Frequency: 20-30% of patients

Difficulty concentrating

(neurologic)

Trouble focusing attention or maintaining mental clarity, often affecting work or school performance.

Frequency: 45-55% of patients

Low blood pressure

(cardiovascular)

Blood pressure reading below normal range, potentially causing dizziness or lightheadedness when standing.

Frequency: 15-25% of patients

Muscle weakness

(constitutional)

Reduced muscle strength making it difficult to perform physical activities that were previously easy.

Frequency: 35-45% of patients
