What is neurotoxicity? 

https://www.ninds.nih.gov/health-information/disorders/neurotoxicity

#

Neurotoxicity occurs when the exposure to natural or manmade toxic substances (neurotoxicants) alters the normal activity of the nervous system. This can eventually disrupt or even kill neurons (nerve cells) which are important for transmitting and processing signals in the brain and other parts of the nervous system.

Neurotoxicity can result from exposure to substances used in chemotherapy, radiation treatment, drug therapies, and organ transplants, as well as exposure to heavy metals such as lead and mercury, certain foods and food additives, pesticides, industrial and/or cleaning solvents, cosmetics, and some naturally occurring substances. Symptoms, which may appear immediately after exposure or be delayed, may include:

• Limb weakness or numbness

• Loss of memory, vision, and/or intellect

• Headache

• Cognitive and behavioral problems

• Sexual dysfunction

Individuals with certain disorders may be especially vulnerable to neurotoxicants.

Treatment involves eliminating or reducing exposure to the toxic substance, followed by symptomatic and supportive therapy. The outlook depends upon the length and degree of exposure and the severity of neurological injury. Many individuals recover completely after treatment. Some individuals may survive but not fully recover. In other instances, exposure to neurotoxicants can be fatal.

什麼是神經毒性？

當接觸天然或人造有毒物質（神經毒物）改變神經系統的正常活動時，就會發生神經毒性。這最終會破壞甚至殺死神經元（神經細胞），神經元對於大腦和神經系統其他部分的訊號傳遞和處理非常重要。

神經毒性可能是由於接觸化療、放射治療、藥物治療和器官移植中使用的物質，以及接觸鉛和汞等重金屬、某些食品和食品添加劑、殺蟲劑、工業和/或清潔溶劑、化妝品而引起的。 ，以及一些天然存在的物質。症狀可能在接觸後立即出現或延遲出現，可能包括：

四肢無力或麻木

喪失記憶、視力和/或智力

頭痛

認知和行為問題

性功能障礙

患有某些疾病的人可能特別容易受到神經毒物的影響。

治療包括消除或減少接觸有毒物質，然後進行症狀和支持性治療。前景取決於暴露的時間和程度以及神經損傷的嚴重程度。許多人在治療後完全康復。有些人可能會倖存，但無法完全康復。在其他情況下，接觸神經毒物可能是致命的。
