Neurologic conditions
Uncommonly, neurologic conditions including autonomic dysreflexia, posttraumatic syringomyelia, stroke, and autonomic neuropathy may cause increased sweating and may lead to night sweats.
Infections
Tuberculosis is the infection most commonly associated with night sweats. But bacterial infections, such as endocarditis (inflammation of the heart valves), osteomyelitis (inflammation in the bones), and abscesses can cause night sweats. Night sweats are also a symptom of HIV infection.
