Will ketamine overdose cause brain damage?
Recent research suggests that there may be another result of ketamine overdose, that being brain damage. Ketamine overdose can cause vision impairment and memory loss. In order to understand how ketamine overdose may cause brain damage, it is first necessary to understand the correlation between the dose of ketamine used and its effects.
How does ketamine work?
The analgesic effects of ketamine work by prevention of central sensitization in certain neurons as well as by the inhibition on the synthesis of nitric oxide. Ketamine can also cause cardiovascular changes and bronchodilation (dilation of the airways in the lungs due to the relaxation of surrounding smooth muscle).
