Myasthenia gravis (MG) is an autoimmune neuromuscular disorder that affects voluntary muscles. Common symptoms can include a drooping eyelid, blurred or double vision, slurred speech, difficulty chewing and swallowing, weakness in the arms and legs, chronic muscle fatigue and difficulty breathing. The weakness tends to increase with continued activity and can be improved with periods of rest.
Neurological complications: numbness, pain, weakness, Bell's palsy (paralysis of the facial muscles), visual disturbances, and meningitis symptoms such as fever, stiff neck, and severe headache. Other problems, which may not appear until weeks, months, or years after a tick bite, include decreased concentration, irritability, memory and sleep disorders, and nerve damage
