We've known that viral infections can be associated with neurological disorders for years. Some of the most common neuro-related diseases caused by viral infections include measles, meningitis, post-infectious encephalomyelitis, subacute sclerosing panencephalitis, chickenpox and polio.
People who have had pneumococcal meningitis often suffer neurological damage ranging from deafness to severe brain damage. Immunizations are available for certain strains of the pneumococcal bacteria. Meningococcal meningitis is caused by the bacterium Neisseria meningitides and is very contagious.
Infections, such as meningitis, encephalitis, polio, and epidural abscess. Structural disorders, such as brain or spinal cord injury, Bell's palsy, cervical spondylosis, carpal tunnel syndrome, brain or spinal cord tumors, peripheral neuropathy, and Guillain-Barré syndrome.
1. Headache. Headaches are one of the most common neurological disorders—and there are a variety of different kinds of headaches, such as migraines, cluster headaches, and tension headaches.
The common causes of bacterial meningitis in the United States include Streptococcus pneumoniae, Neisseria meningitidis, group B Streptococcus spp., Listeria monocytogenes, and Haemophilus influenzae.
headache – which is often severe, located in a single section of the head and cannot be relieved with painkillers. changes in mental state – such as confusion or irritability. problems with nerve function – such as muscle weakness, slurred speech or paralysis on one side of the body. a high temperature.
The commonest causes of acute viral meningitis are enteroviruses and mumps virus. Encephalitis is a clinical syndrome in which, in addition to fever, headache and stiff neck, there is paralysis, seizures or other evidence of parenchymal disease of the brain.
A cerebral abscess is an infection in your brain. It is a medical emergency that requires treatment right away. Symptoms can include headache, fever, changes in consciousness, confusion, neck stiffness, vomiting, seizures, weakness, trouble moving, and changes in vision.
Neurological effects of systemic inflammation
Systemic inflammation can lead to immune responses in the brain that show up in many ways. People may experience cognitive symptoms such as memory lapses or confusion. Other common symptoms, known as “sickness behavior,” may include: Depression.
The most common causes of non-neonatal bacterial meningitis are Neisseria meningitidis, Streptococcus pneumoniae, and Haemophilus influenzae. All three of these bacterial pathogens are spread from person to person by respiratory secretions.
A CT of the brain may be performed to assess the brain for tumors and other lesions, injuries, intracranial bleeding, structural anomalies (e.g., hydrocephalus , infections, brain function or other conditions), particularly when another type of examination (e.g., X-rays or a physical exam) are inconclusive.
Currently, most of the brain and spinal infections are diagnosed with the use of magnetic resonance imaging (MRI).
Among the most common are epilepsy, Alzheimer's, and stroke.
Neurological disorders are central and peripheral nervous system diseases, that is, they occur in the brain, spine, and multiple nerves that connect both.
Chemical and metabolic testing of the blood can indicate some muscle disorders, protein or fat-related disorders that affect the brain and inborn errors of metabolism. Blood tests can monitor levels of therapeutic drugs used to treat epilepsy and other neurological disorders.
Physical signs of neurological problems may include partial or complete paralysis, muscle weakness, seizures, unexplained pain, or numbness. Spasticity is when muscles become tense and rigid and your reflexes may be exaggerated. This can affect the way you walk, move, or even speak.
You routinely wake up with a headache. Your headaches are accompanied by other neurological symptoms, such as vision changes, dizziness, nausea or even seizures (if you start vomiting or lose consciousness, go to the emergency room right away).
Sepsis and septic shock can result from an infection anywhere in the body, such as pneumonia, influenza, or urinary tract infections. Bacterial infections are the most common cause of sepsis. Worldwide, one-third of people who develop sepsis die.
