How do neurological diseases occur?

The nervous system is one of the most important systems in the human body. The nerves are responsible for the body's various stress responses. Only a healthy nervous system can enable people to carry out various actions smoothly in life. The nervous system is also easily affected and damaged. The resulting diseases are called neurological diseases. Let’s take a look at how neurological diseases arise.

Infect

Neurological disorders can occur from a variety of causes. The causes of many neurological diseases remain unclear.

Including bacterial infections, such as purulent meningitis and brain abscesses, caused by various purulent bacteria; viral infections, such as epidemic encephalitis caused by Japanese encephalitis virus, epidemic chest pain caused by type B Kukusaki virus, poliomyelitis caused by poliovirus, kuru or slow virus infection, and subacute sclerosing panencephalitis may be caused by mutant strains of measles virus;

Infections caused by parasitic infections, such as cerebral malaria, cerebral paragonimiasis, and cerebral cysticercosis; fungal infections, such as Candida albicans and cryptococcal meningitis; Leptospira can also cause meningoencephalitis. Epilepsy is caused in part by local scarring of the brain and brain infections.

Poisoning

Including metal poisoning, such as lead poisoning can cause peripheral motor nerve paralysis, lead encephalopathy, mercury, arsenic, and thallium poisoning also affect the nervous system; organic poisoning, such as alcohol poisoning, barbiturate poisoning can inhibit the central nervous system, organophosphorus poisoning causes overexcitement of choleretic nerves; bacterial toxin poisoning, such as botulism poisoning can cause cranial nerve paralysis and limb weakness, diphtheria toxin can cause nerve paralysis, tetanus toxin can cause systemic skeletal muscle rigidity and spasm; animal poisons (toxins contained in coelenterates, shellfish, poisonous mosquitoes, spiders, pufferfish, etc.) can also cause neurological symptoms (muscle weakness, paralysis, convulsions, ataxia, etc.).
