<unk>  (as known as<unk> ic aseptic meningitis or<unk>  neurosyphilis) is a chronic form of<unk>  infection that affects the central nervous system. Treponema pallidum, a spirochate bacterium, is the main cause of<unk> , which spreads drastically throughout the body and can infect all its systems if not treated appropriately. Treponema pallidum is the main cause of the onset of<unk>  and other treponemal diseases, and it consists of a cytoplasmic and outer membrane that can cause a diverse array of diseases in the central nervous system and brain. Early symptomatic neurosyphilis (or acute<unk> ic meningitis or neurorecurrence) is the onset of<unk> . The symptoms arise as a result of inflamed meninges, which eventually lead up to signs of meningitis. Treponema pallidum invades the nervous system within three to eighteen months after the primary infection. The initial series of events is asymptomatic meningitis, which can remain in the human body system and produce more damage within the body. Every form of neurosyphilis has meningitis as a component; however, every case differs in severity. The individual is infected with<unk>  through a gram negative bacteria that only humans can obtain.<unk>  has four stages of infection, which are primary, secondary, latent, and tertiary. If<unk>  is not treated, the disease can affect various other systems in the body, including the brain, heart, and vessels. The infection of the heart and vessels leads to meningovascular<unk> , which is usually presented during the secondary stage of<unk> . If<unk>  is prolonged, it can affect the nervous system, which is known as neurosyphilis.<unk>  is a component of neurosyphilis, which usually occurs in the tertiary stage of<unk> .
