  • Aspergillosis: Infection with a fungus called Aspergillus.
  • Bacterial meningitis: Bacterial meningitis is a form of meningitis caused by bacteria that normally lives in the mouth and throat. When the immune system is unable to supress this bacteria, it travels to the cerebrospinal spinal fluid in the brain. From there it affects the membranes surrounding the brain.
  • Brain conditions: Medical conditions that affect the brain
  • Cryptococcal Meningitis: Cryptococcal meningitis is an infection of the meninges (the membranes covering the brain and spinal cord), caused by the fungus Cryptococcus neoformans.
  • Eastern equine encephalitis: Is a mosquito born virus that occurs in the eastern united states and causes disease in humans, horses and some birds
  • Encephalitis: Dangerous infection of the brain
  • Encephalitis, California serogroup viral: A mosquito borne viral illness
  • Epilepsy: Brain condition causing seizures or spasms.
  • Fever: Elevation of the body temperature above the normal 37 degrees celsius
  • Fungal meningitis: Fungal meningitis is an infection that causes swelling and irritation of the tissue around the brain and spinal cord. It usually strikes people whose weakened immune systems can't fight off infection. The disease is not common. but it can be very serious.
  • Granulomatous amebic encephalitis: Brain/CNS infection from Acanthamoeba bacteria
  • Head Conditions: Conditions that affect the head
  • Headache: In medicine a headache or cephalalgia is a symptom of a number of different conditions of the head and sometimes neck. Some of the causes are benign while others are medical emergencies. It ranks among the most common pain complaints
  • Hydrocephalus: A rare condition where the normal flow of cerebrospinal fluid is impaired by dilated brain ventricles which causes the fluid to accumulate in the skull and hence result in increased brain pressure.
  • Inflammatory conditions that may be pathogenic or non-pathogenic: Medical conditions causing inflammation, whether due to a pathogen (e.g. bacteria, virus), or a systemic or other cause.
  • Japanese encephalitis: A form of encephalitis caused by a flavivirus (Japanese B encephalitis virus - JBEV) and transmitted by mosquito bites. Most cases are mild and asymptomatic but severe cases can lead to death.
  • Labrynthitis: Inner ear condition affecting various ear structures
  • Lymphocytic Choriomeningitis: Rodent-borne viral disease often causing meningitis or encephalitis
  • Meninges cancer: A disorder where a cancerous malignancy is found in the meninges of the brain
  • Meningioma: A slow-growing tumor of the meninges that is not cancerous. Symptoms are determined by the size and location of the tumor.
  • Meningitis: Dangerous infection of the membranes surrounding the brain.
  • Meningococcal disease: Dangerous bacterial infection causing meningitis or bacteremia.
  • Murray Valley encephalitis: Severe viral form of encephalitis in Australia
  • Nausea: The queasy feeling of nausea and often also vomiting.
  • Nervous system conditions: Diseases affecting the nerves and the nervous system.
  • Papilledema: Swelling of the head of the optic nerve (optic disk) due to increased intracranial pressure.
  • Pneumococcal meningitis: Pneumococcal meningitis is an inflammation or infection of the membranes covering the brain and spinal cord caused by Streptococcus pneumoniae (also called pneumococcus).
  • Rabies: An infectious disease that can affect any mammal including humans and is transmitted through the saliva of an infected animal. The infectious agent is the Neurotropic lyssavirus which affects the salivary gland and also causes neurological symptoms.
  • Rasmussen's Encephalitis: Rare possibly-autoimmune brain condition.
  • Simian B virus infection: A type of herpesvirus which occurs in monkeys but can be transmitted to humans through bites or through contact with infected monkey tissue as in a laboratory situation. The virus infects the brain (encephalitis) and the surrounding membrane (meningitis).
  • Sinusitis: Sinusitis is an inflammation of the paranasal sinuses.
  • St. Louis encephalitis: Mosquito-borne type of brain infection (encephalitis)
  • Stiff neck: Reduced mobility of the neck
  • Subacute Sclerosing Panencephalitis: A progressive neurological disorder involving inflammation of the brain caused by a complication of the measles virus. It can occur up to 10 years after the initial measles virus and may be due to a defective immune response to the virus or a reactivation of the virus.
  • TORCH Syndrome: Infection of a fetus by any of a group of infectious agents which have been transmitted from the mother through the placenta. The infections include toxoplasmosis, rubella, cytomegalovirus, herpes virus, hepatitis and syphilis. The severity and nature of symptoms is determined by the type of infection.
  • Viral meningitis: Viral meningitis refers to meningitis caused by a viral infection
  • Vomiting: Vomiting or retching symptoms.
  • Western equine encephalitis: An infectious disease caused by an arbovirus (Alphavirus - Togaviraidae) and transmitted by infected mosquitoes. The infection primarily attacks that central nervous system and severity can range from asymptomatic to severe complications and even death in rare cases.
